  • jquery image fading with tabs

    - by StealthRT
    Hey all, i am trying my best to figure out how to go about doing this: I have 2 tabs. When the page loads tab1 is selected automatically. This shows the tab as 1.0 transparency while tab2 stays at 0.7. Once the user clicks on tab2, tab1 goes to 0.7 transparency and tab2 goes to 1.0. However, i can not seem to get it to do that! Here is my code: <script type="text/javascript"> function checkTab(theTab) { $('#tab1').fadeTo(250, 0.70); $('#tab2').fadeTo(250, 0.70); if ($("#tabActive").val() == theTab) { $(theTab).fadeTo(250, 1); } } $(document).ready(function() { $('#tab1').hover(function() {$(this).fadeTo(250, 1)}, function() {checkTab('#tab1')}); $('#tab2').hover(function() {$(this).fadeTo(250, 1)}, function() {checkTab('#tab2')}); $('#tab2').fadeTo(250, 0.70); $('#tabActive').val('tab1'); }); </script> <li class="stats"><img src="images/Stats.png" name="nav1" width="70" height="52" id="tab1" onclick="$('#tabActive').val('tab1');" /></li> <li class="cal"><img src="images/cal.png" name="nav1" width="70" height="52" id="tab2" onclick="$('#tabActive').val('tab2');" /></li> <input name="tabActive" id="tabActive" type="text" /> Any help would be great! :) David

  • I am looking for an actual functional web browser control for .NET, maybe a C++ library

    - by Joshua
    I am trying to emulate a web browser in order to execute JavaScript code and then parse the DOM. The System.Windows.Forms.WebBrowser object does not give me the functionality I need. It let's me set the headers, but you cannot set the proxy or clear cookies. Well you can, but it is not ideal and messes with IE's settings. I've been extending the WebBrowser control pinvoking native windows functions so far, but it is really one hack on top of another. I can mess with the proxy and also clear cookies and such, but this control has its issues as I mentioned. I found something called WebKit .NET (http://webkitdotnet.sourceforge.net/), but I don't see support for setting proxies or cookie manipulation. Can someone recommend a c++/.NET/whatever library to do this: Basically tell me what I need to do to get an interface to similar this in .NET: // this should probably pause the current thread for the max timeout, // throw an exception on failure or return null w/e, VAGUELY similar to this string WebBrowserEmu::FetchBrowserParsedHtml(Uri url, WebProxy p, int timeoutSeconds, byte[] headers, byte[] postdata); void WebBrowserEmu::ClearCookies(); I am not responsible for my actions.

  • properly format postal address with line breaks [google maps]

    - by munchybunch
    Using V3 of the google maps API, is there any reliable way to format addresses with the line break? By this, I mean something like 1600 Amphitheatre Parkway Mountain View, CA 94043 should be formatted as 1600 Amphitheatre Parkway Mountain View, CA 94043 Looking through the response object from geocoding, there is an address_components array that has, for the above address, 8 components (not all of the components are used for the address): 0: Object long_name: "1600" short_name: "1600" types: Array[1] 0: "street_number" length: 1 1: Object long_name: "Amphitheatre Pkwy" short_name: "Amphitheatre Pkwy" types: Array[1] 0: "route" length: 1 2: Object long_name: "Mountain View" short_name: "Mountain View" types: Array[2] 0: "locality" 1: "political" length: 2 3: Object long_name: "San Jose" short_name: "San Jose" types: Array[2] 0: "administrative_area_level_3" 1: "political" length: 2 4: Object long_name: "Santa Clara" short_name: "Santa Clara" types: Array[2] 0: "administrative_area_level_2" 1: "political" length: 2 5: Object long_name: "California" short_name: "CA" types: Array[2] 0: "administrative_area_level_1" 1: "political" length: 2 6: Object long_name: "United States" short_name: "US" types: Array[2] 0: "country" 1: "political" length: 2 7: Object long_name: "94043" short_name: "94043" types: Array[1] 0: "postal_code" length: 1 I was thinking that you could just combine parts that you want, like sprintf("%s %s<br />%s, %s %s", array[0].short_name, array[1].short_name, array[2].short_name, array[5].short_name, array[7].short_name) [edit]I just realized that sprintf isn't defined by default in JavaScript, so just a concatenation would do I guess.[/edit] But that seems awfully unreliable. Does anyone know the details on the structure of address_components, and if it's reliably similar like that for street addresses in the US? If I wanted to, I guess I could look for the proper types (street_number,route, etc) as well. I'd love it if anyone had a better way than what I"m doing here...

  • Hide a single content block from search engines?

    - by jonas
    A header is automatically added on top of each content URL, but its not relevant for search and messing up the all the results beeing the first line of every page (in the code its the last line but visually its the first, which google is able to notice) Solution1: You could put the header (content to exculde from google searches) in an iframe with a static url domain.com/header.html and a <meta name="robots" content="noindex" /> ? - are there takeoffs of this solution? Solution2: You could deliver it conditionally by apache mod rewrite, php or javascript -takeoff(?): google does not like it? will google ever try pages with a standard users's useragent and compare? -takeoff: The hidden content will be missing in the google cache version as well... example: add-header.php: <?php $path = $_GET['path']; echo file_get_contents($_SERVER["DOCUMENT_ROOT"].$path); ?> apache virtual host config: RewriteCond %{HTTP_USER_AGENT} !.*spider.* [NC] RewriteCond %{HTTP_USER_AGENT} !Yahoo.* [NC] RewriteCond %{HTTP_USER_AGENT} !Bing.* [NC] RewriteCond %{HTTP_USER_AGENT} !Yandex.* [NC] RewriteCond %{HTTP_USER_AGENT} !Baidu.* [NC] RewriteCond %{HTTP_USER_AGENT} !.*bot.* [NC] RewriteCond %{SCRIPT_FILENAME} \.htm$ [NC,OR] RewriteCond %{SCRIPT_FILENAME} \.html$ [NC,OR] RewriteCond %{SCRIPT_FILENAME} \.php$ [NC] RewriteRule ^(.*)$ /var/www/add-header.php?path=%1 [L]

  • How can I get the main thread to sleep while waiting for a delgate to be called?

    - by Erik B
    Consider a class with these methods: - (id) initWithFrame: (CGRect) frame { if (!(self = [super init])) return nil; webView = [[UIWebView alloc] initWithFrame:frame]; [webView setDelegate:self]; lock = [[NSConditionLock alloc] initWithCondition:LOCK_WAIT]; return self; } - (void) setHTML: (NSString *) html { [lock lockWhenCondition:LOCK_WAIT]; [webView loadHTMLString:html baseURL:nil]; [lock unlock]; } - (void)webViewDidFinishLoad:(UIWebView *)aWebView { [lock lockWhenCondition:LOCK_WAIT]; // Locking to be able to unlock and change the condition. [lock unlockWithCondition:LOCK_GO]; } - (NSString *) stringByEvaluatingJavaScriptFromString: (NSString *) jsCommand { [lock lockWhenCondition:LOCK_GO]; return [webView stringByEvaluatingJavaScriptFromString:jsCommand]; [lock unlock]; } Let's call this class SynchronousUIWebView. From the main thread I execute: webView = [[SynchronousUIWebView alloc] initWithFrame:frame]; [webView setHTML:html]; [webView stringByEvaluatingJavaScriptFromString:jsCommand]; The problem seems to be that the delegate is not called until I leave the current call stack, which I don't since I'm waiting for the delegate call to happen, aka deadlock. To me it seems like the delegate call is pushed to a queue that is called when the current call is done. So the question is can I modify this behavior? Note: The reason this is needed is that I can't execute the JavaScript until the HTML has loaded.

  • Help with jQuery Validation plugin and a form that uses 'panels'

    - by alex
    I have a form that works in 'sections' that I will refer to as 'panels'. By default, the form is listed out on the page, one panel after the other. However, with JavaScript, it puts the panels into one panel viewer, and displays them one after the other (with prev/next buttons). Example Form Workflow Panel 1: User Details - Panel 2: User Location - Panel 3: User Info - Panel 4: Confirm Details I am using the jQuery Validation plugin. My problem is, I have set up all the rules for all the inputs in the first 3 panels, and I'd like to be able to only validate a subset of them per panel. Example, when pushing 'next panel' after completing name & email (in the 1st, user details panel), I'd like to do a validation only on that panel first, and then get a boolean response (if the 1st panel validated), and if true, then proceed to the next panel. I've played around with a bit of the config, but unfortunately could not get it to work as I wanted. This is my first project with this plugin so I'm quite new to it! Is there a way to add rules dynamically to the plugin? i.e. not on $('form').validate(options) ? What I'd like to do, is call the validate() on the form, with all the error messages, and then on the 'next panel' code, do a switch case to determine which rules to add, and then call a validate() myself.

  • How to bind to another event after ajax call in jquery

    - by robert
    Hi, I'm creating a graph using flot javascript library. I have enabled clickable event and the div is binded to plotclick event. So, when a datapoint is clicked, an ajax call is made and the result is used to replace the current div. After this i need to bind the div to a new event. I tried to call bind, but it is still bound to old callback. When i call unbind and bind, the new callback is not called. var handleTeacherClick = function( event, pos, item ) { if( typeof item != "undefined" && item ) { var user_id = jQuery( 'input[name="id' + item.datapoint[0] + '"]' ).val(); jQuery.ajax({ type: 'POST', url: BASEPATH + 'index.php/ajax/home/latest', data: { "user_id": user_id }, dataType: 'json', success: function ( result ) { jQuery.plot(jQuery('#stats_prog'), result.progress_data, result.progress_options); jQuery.plot(jQuery('#stats_perf'), result.performance_data, result.performance_options); jQuery('.stats_title'). html('<span class="stats_title">'+ ' >> Chapter '+Math.ceil(item.datapoint[0])+'</span>'); jQuery('#stats_prog')./*unbind("plotclick").*/ bind('plotclick', statClickHandler ); jQuery('#stats_perf')./*unbind("plotclick"). */ bind( 'plotclick', statClickHandler ); }, }); } }

  • jeditable table cell

    - by user666262
    Hi all, I am having an issue when using jeditable to edit a cell in a table. The project is the MVC 2 web application and the table has been put on the standard about page. How do i tell the script to call a specific method in the controller ? because it is currently just loading the entire page into the cell. This is the javascript: $(document).ready(function () { $('.editable').editable('http://localhost:2196/Home/About', { type: 'text', cancel: 'Cancel', event: 'dblclick', submit: 'OK', tooltip: 'double Click to edit...' }); }); This is the table : <% foreach (DataTableEditable.Models.Company item in (IEnumerable<DataTableEditable.Models.Company>)Model) {%> <tr id="<%= Html.Encode(item.ID) %>"> <td class="editable"><%= Html.Encode(item.Name) %> </td> <td><%= Html.Encode(item.Address) %> </td> <td><%= Html.Encode(item.Town) %> </td> </tr> <% }%> Thanks lots John

  • Does cout need to be terminated with a semicolon ?

    - by Philippe Harewood
    I am reading Bjarne Stroustrup's Programming : Principles and Practice Using C++ In the drill section for Chapter 2 it talks about various ways to look at typing errors when compiling the hello_world program #include "std_lib_facilities.h" int main() //C++ programs start by executing the function main { cout << "Hello, World!\n", // output "Hello, World!" keep_window_open(); // wait for a character to be entered return 0; } In particular this section asks: Think of at least five more errors you might have made typing in your program (e.g. forget keep_window_open(), leave the Caps Lock key on while typing a word, or type a comma instead of a semicolon) and try each to see what happens when you try to compile and run those versions. For the cout line, you can see that there is a comma instead of a semicolon. This compiles and runs (for me). Is it making an assumption ( like in the javascript question: Why use semicolon? ) that the statement has been terminated ? Because when I try for keep_terminal_open(); the compiler informs me of the semicolon exclusion.

  • How can I run Ruby specs and/or tests in MacVim without locking up MacVim?

    - by Henry
    About 6 months ago I switched from TextMate to MacVim for all of my development work, which primarily consists of coding in Ruby, Ruby on Rails and JavaScript. With TextMate, whenever I needed to run a spec or a test, I could just command+R on the test or spec file and another window would open and the results would be displayed with the 'pretty' format applied. If the spec or test was a lengthy one, I could just continue working with the codebase since the test/spec was running in a separate process/window. After the test ran, I could click through the results directly to the corresponding line in the spec file. Tim Pope's excellent rails.vim plugin comes very close to emulating this behavior within the MacVim environment. Running :Rake when the current buffer is a test or spec runs the file then splits the buffer to display the results. You can navigate through the results and key through to the corresponding spot in the file. The problem with the rails.vim approach is that it locks up the MacVim window while the test runs. This can be an issue with big apps that might have a lot of setup/teardown built into the tests. Also, the visual red/green html results that TextMate displays (via --format pretty, I'm assuming) is a bit easier to scan than the split window. This guy came close about 18 mos ago: http://cassiomarques.wordpress.com/2009/01/09/running-rspec-files-from-vim-showing-the-results-in-firefox/ The script he has worked with a bit of hacking, but the tests still ran within MacVim and locked up the current window. Any ideas on how to fully replicate the TextMate behavior described above in MacVim? Thanks!

  • Any solution to IE8 bug rendering error when hiding elements?

    - by Magnar
    Bug: when hiding an element with JavaScript in IE8, the margin of still-visible other elements on the side is ignored. This bug has been introduced with IE8, since it works as expected in IE6+7 (and other browsers). <html> <head> <style> #a, #b, #c, #d {background: #ccf; padding: 4px; margin-bottom: 8px;} </style> </head> <body> <div id="a">a</div> <div id="b">b</div> <div id="c">c</div> <div id="d">d</div> <script> setTimeout(function () { document.getElementById("b").style.display = "none"; }, 1000); </script> </body> </html> When running this code, notice how a and c have a margin of 8 between them in normal browsers, but a margin of 0 in IE8. Remove the padding, and IE8 behaves like normal. Remove the timeout and IE8 behaves like normal. A border behaves the same way. I've been working with IE-bugs the last 10 years, but this has me stumped. The solution for now is to wrap the divs, and apply the margin to the outer element and other styles to the inner. But that's reminicent of horrible IE6-workarounds. Any better solutions?

  • asp.net mvc ajax helper/post additional data w/o jquery.

    - by Jopache
    I would like to use the ajax helper to create ajax requests that send additional, dynamic data with the post (for example, get the last element with class = blogCommentDateTime and send the value of that last one to the controller which will return only blog comments after it). I have successfully done so with the help of jQuery Form plugin like so: $(document).ready(function () { $("#addCommentForm").submit(function () { var lastCommentDate = $(".CommentDateHidden:last").val(); var lastCommentData = { lastCommentDateTicks: lastCommentDate }; var formSubmitParams = { data: lastCommentData, success: AddCommentResponseHandler } $("#addCommentForm").ajaxSubmit(formSubmitParams); return false; }); This form was created with html.beginform() method. I am wondering if there is an easy way to do this using the ajax.beginform() helper? When I try to use the same code but replace html.beginform() with ajax.beginform(), when i try to submit the form, I am issuing 2 posts (which is understandable, one being taken care of by the helper, the other one by me with the JS above. I can't create 2 requests, so this option is out) I tried getting rid of the return false and changing ajaxSubmit() to ajaxForm() so that it would only "prepare" the form, and this leads in only one post, but it does not include the extra parameter that I defined, so this is worthless as well. I then tried keeping the ajaxForm() but calling that whenever the submit button on the form gets clicked rather than when the form gets submitted (I guess this is almost the same thing) and that results in 2 posts also. The biggest reason I am asking this question is that I have run in to some issues with the javascript above and using mvc validation provided by the mvc framework (which i will set up another question for) and would like to know this so I can dive further in to my validation issue.

  • Anchor as a Submit button

    - by griegs
    I have an MVC 2 application that has the following on it; <% using( Html.BeginForm("Results","Quote", FormMethod.Post, new { name="Results" })){ %> <% Html.RenderPartial("Needs", Model.needs); %> <div class="But green" style=""> <a href="." onclick="javascript:document.Results.submit();">Go</a> </div> <input type="submit" /> <%} %> Pressing the Submit button or the anchor both post back to the right ActionResult. However, when in the controller I return View(stuff..) only the Submit button will come back to the page. When the call finishes from pressing the anchor, I go to an error page informing me that the resource cannot be found. I suspect it has something to do with href="." but am unsure what to set it to.

  • HTML Submit button vs AJAX based Post (ASP.NET MVC)

    - by Graham
    I'm after some design advice. I'm working on an application with a fellow developer. I'm from the Webforms world and he's done a lot with jQuery and AJAX stuff. We're collaborating on a new ASP.MVC 1.0 app. He's done some pretty amazing stuff that I'm just getting my head around, and used some 3rd party tools etc. for datagrids etc. but... He rarely uses Submit buttons whereas I use them most of the time. He uses a button but then attaches Javascript to it that calls an MVC action which returns a JSON object. He then parses the object to update the datagrid. I'm not sure how he deals with server-side validation - I think he adds a message property to the JSON object. A sample scenario would be to "Save" a new record that then gets added to the gridview. The user doesn't see a postback as such, so he uses jQuery to disable the UI whilst the controller action is running. TBH, it looks pretty cool. However, the way I'd do it would be to use a Submit button to postback, let the ModelBinder populate a typed model class, parse that in my controller Action method, update the model (and apply any validation against the model), update it with the new record, then send it back to be rendered by the View. Unlike him, I don't return a JSON object, I let the View (and datagrid) bind to the new model data. Both solutions "work" but we're obviously taking the application down different paths so one of us has to re-work our code... and we don't mind whose has to be done. What I'd prefer though is that we adopt the "industry-standard" way of doing this. I'm unsure as to whether my WebForms background is influencing the fact that his way just "doesn't feel right", in that a "submit" is meant to submit data to the server. Any advice at all please - many thanks.

  • regular expression for emails NOT ending with replace script

    - by corroded
    I'm currently modifying my regex for this: http://stackoverflow.com/questions/2782031/extracting-email-addresses-in-an-html-block-in-ruby-rails basically, im making another obfuscator that uses ROT13 by parsing a block of text for all links that contain a mailto referrer(using hpricot). One use case this doesn't catch is that if the user just typed in an email address(without turning it into a link via tinymce) So here's the basic flow of my method: 1. parse a block of text for all tags with href="mailto:..." 2. replace each tag with a javascript function that changes this into ROT13 (using this script: http://unixmonkey.net/?p=20) 3. once all links are obfuscated, pass the resulting block of text into another function that parses for all emails(this one has an email regex that reverses the email address and then adds a span to that email - to reverse it back) step 3 is supposed to clean the block of text for remaining emails that AREN'T in a href tags(meaning it wasn't parsed by hpricot). Problem with this is that the emails that were converted to ROT13 are still found by my regex. What i want to catch are just emails that WEREN'T CONVERTED to ROT13. How do i do this? well all emails the WERE CONVERTED have a trailing "'.replace" in them. meaning, i need to get all emails WITHOUT that string. so far i have this regex: /\b([A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}('.replace))\b/i but this gets all the emails with the trailing '.replace i want to get the opposite and I'm currently stumped with this. any help from regex gurus out there? MORE INFO: Here's the regex + the block of text im parsing: http://www.rubular.com/r/NqXIHrNqjI as you can see, the first two 'email addresses' are already obfuscated using ROT13. I need a regex that gets the emails [email protected] and [email protected]

  • JAX-RS --- How to return JSON and HTTP Status code together?

    - by masato-san
    I'm writing REST web app (Netbean6.9, JAX-RS, Toplink-essential) and trying to return JSON and Http status code. I have code ready and working just to return JSON when HTTP GET Method is called from client. Code snippet @Path("get/id") @GET @Produces("application/json") public M_?? getMachineToUpdate(@PathParam("id") String id) { //some code to return JSON . . return myJson But I also want to return HTTP status code (500, 200, 204 etc) along with returning JSON. I tried using HttpServletResponse object, response.sendError("error message", 500); But this made browser to think it's real 500 so output web page was regular Http 500 error page. What I want to is just to return status code so that my Javascript on client side can handle some logic depending on what HTTP status code is returned. (maybe just to display the error code and message on html page.) Is it possible to do so? or should HTTP status code not be used for such thing?

  • The perfect web UI framework (with Microsoft stack?) - architecture question?

    - by Igorek
    I'm looking for suggestions for the following issue, and I realize there is really not going to be a perfect answer to my question: I have a UI built in WinForms.NET (v4.0 framework) with WCF back-end and EF4 model objects, that I am looking to port to the web. UI is not huge and is not super complex and is structured well. But it is not a super simple system either. I am looking to pick a technology stack for the web-frontend that will target desktop & partially mobile platforms, provide a good development platform to build on, and facilitate code reuse across UI and back-end tiers... I would rather avoid: custom coding of UI-centric scripts, because they are hard to debug, non-compiled, usually a maintenance nightmare, almost always start to contain business logic, and duplicate some of the logic that back-end tiers have (especially validation) custom-coding for Desktop Web and Mobile Web UI's separately (although I realize that mobile web UI will likely contain fewer of data-entry screens and more reporting screens) non-.NET technology stacks I would love to: target the reporting capabilities of the system toward mobile web browsers not have to write a single line of script (javascript, jquery, etc.) utilize a good collection of controls that produces an elegant UI use .NET for everything The way I see it right now, I need to re-write this app in Silverlight, utilize a 3rd party UI framework like Telerik, and re-do the reports UI again for mobile platforms separately. However, I'm rather concerned about the shelf-life of Silverlight and the needed to deploy a different architecture to deal with mobile platform. Is there an ASP.NET/MVC/Ajax architecture/framework/library that would allow me to get at the power of .NET and without painful (imho) client-side scripting, while providing a decent user experience Thank you

  • OnSubmit does work right in the Validation plugin in jQuery

    - by novellino
    Hello, I an quite new to jQuery and I have a problem while trying to create a form. I am using the Validation plugin for validate the email (one the form's field). When I click the Submit button I want to call my own function because I want to save the data in an XML file. This is my button: (as I understood the plugin uses "submit" for understand the button) <input type="submit" name="submit" class="submit" id="submit_btn" value="Send"/> and here is the script for the validation: <script type="text/javascript"> $(document).ready(function() { //this is my form $("#contactForm").validate(); /*save the valid data in the xml*/ $(".submit").click(function() { var email = $("input#email").val(); var subject = $("input#subject").val(); var message = $("textarea#message").val(); if (email == "" || !$("#contactForm").valid()) { return false; } var dataString = 'email='+ email + '&subject=' + subject + '&message=' + message; //alert("DATA: " +dataString); $.ajax({ type: "POST", url: "SaveData.jsp", data: dataString, success: function(data){} }); return false; }); }); In general it works ok but I have two basic problems. When I click the button in the beginning having all the form empty, I get no message for the field required. Also when the data are valid and I am doing the submit, the form does not become clear after the submit. If I deleted this script code, these actions are working properly but I can not save the data! Does anyone know what is wrong? Thanks a lot!

  • How best to associate code with events in jQuery?

    - by Ned Batchelder
    Suppose I have a <select> element on my HTML page, and I want to run some Javascript when the selection is changed. I'm using jQuery. I have two ways to associate the code with the element. Method 1: jQuery .change() <select id='the_select'> <option value='opt1'>One</option> <option value='opt2'>Two</option> </select> <script> $('#the_select').change(function() { alert('Changed!'); }); </script> Method 2: onChange attribute <select id='the_select' onchange='selectChanged();'> <option value='opt1'>One</option> <option value='opt2'>Two</option> </select> <script> function selectChanged() { alert('Changed!'); } </script> I understand the different modularity here: for example, method 1 keeps code references out of the HTML, but method 2 doesn't need to mention HTML ids in the code. What I don't understand is: are there operational differences between these two that would make me prefer one over the other? For example, are there edge-case browsers where one of these works and the other doesn't? Is the integration with jQuery better for either? Does the late-binding of the code to the event make a difference in the behavior of the page? Which do you pick and why?

  • jQuery AJAX with two domains

    - by Andrew Burns
    OK here is the situation: I have an externally hosted CMS which works great for 99% of our needs. However on the more advanced things I inject my own CSS+JS and do magic. The problem I am running into is loading a simple HTML page from jQuery.ajax() calls. It appears to work in the sense that no warnings or errors are thrown; however in my success handler (which IS ran), the response is blank! I have been scratching my head for the whole morning trying to figure this out and the only thing I can think of is that is has something to do with the cross domain issue (even though it appears to work). Injected JavaScript: $(document).ready(function() { doui(); }); function doui() { $.ajax({ url: 'http://apps.natronacounty-wy.gov/css/feecalc/ui.htm', cache: false, success: ajax_createUI, charset: "utf-8", error: function(e) { alert(e); } }); } function ajax_createUI(data, textStatus) { alert(data); $("#ajax-content").html(data); } My ajax_createUI() success handler is called and textStatus is "success"; however data is empty. This JS file resides @ http://apps.natronacounty-wy.gov/css/js/feecalc.js however the CMS website (which gets the JS injected into it) resides @ http://www.natronacounty-wy.gov/ Am I just being stupid or is it a bug that it looks like it should be working but isn't?

  • ASP MVC Controller Method not always called from $.getJSON request

    - by johnvpetersen
    I have a controller method that returns a jSON object and in one calling situation, it works and in another calling situation, it does not work. When the URL in my browser is this: http://localhost:65247/Client -- it works. But, when my url looks like this: http://localhost:65247/Client/UserAdmin?id=6 -- it DOES NOT work In a nutshell, clients have users. From within the client, I wish to work on a specific user (this is the UserAdmin view). In this case, the client id is 6. From within the UserAdmin view that was launched with Id=6, I then wish to select a user from a dropdown. The idea was to use javascript and $.getJSON to fetch data for the specific user so as not to have to refresh the entire page. I use this approach in other parts of the app. The only difference I can see is with the URL in the browser. It would appear the presence of parameters via the '?' is futzing things up a bit. Any ideas?? Thanks in advance. John

  • jQuery weirdness. Div becomes attached to chained element markup?

    - by Scott B
    I've got a div in my app that is displayed each time my theme options panel is "saved". The markup is... <form method="post"> <?php if ( $_REQUEST['saved']) { ?> <div id="message" class="updated fade"><p>Sweet! The settings were saved :)</p></div> <script type="text/javascript"> $('#message').delay(3000).fadeOut(3000);</script> <?php }?> This has the effect of showing the div (which is absolutely positioned to overlay the interface). I'm also using jQuery to fade the message offscreen after 3 seconds. This works fine, however, when I add a bit of script to my jQuery chain (see the commented out block below), the message div is only visible when the jPicker popup appears. $(function() { $("#carousel").jCarouselLite ( { btnNext: ".next", btnPrev: ".prev", visible: 6, speed: 700 } ); $('#carousel').show(); $('#myTheme').change ( function() { var myImage = $('#myTheme :selected').text(); $('.selectedImage img').attr('src','../wp-content/themes/myTheme/styles/'+myImage+'/screenshot.jpg'); } ); $('#carousel ul li').click ( function(e) { var myOption = $(this).children('img').attr('title'); $("#myTheme option[value='"+myOption+"']").attr('selected', 'selected'); $("#myTheme").css('backgroundColor', '#A9A9A9').animate({backgroundColor: "#ffffff"}, 'slow'); } ); $('#carousel ul li').hover ( function(e) { var img_src = $(this).children('img').attr('src'); $('.selectedImage img').attr('src',img_src); } ,function() { $('.selectedImage img').attr('src', '<?php echo $selectedThumb; ?>'); } ); /* $('#myTheme_sidebar_color').jPicker ( {}, function(color) { $(this).val(color.get_Hex()); }, function(color) { $(this).val(color.get_Hex()); } ); */ });
