  • Getting a Script Error Every Time I Click a Link

    - by Flip4Life
    I have everything working perfectly on my site, but for some reason, I get an error message in console whenever I click a link anywhere on my site. The error has to do with this line of coding here: jQuery(function($){ $('.navbar a, .scroll a, .smoothscroll a').bind('click',function(event){ var $anchor = $(this); $('html, body').stop().animate({ scrollTop: $($anchor.attr('href')).offset().top }, 850,'easeInOutExpo'); event.preventDefault(); }); }); And the error I am getting is this: "SCRIPT5007: Unable to get value of the property 'top': object is null or undefined custom.min.js, line 6 character 197" The exact code it is highlighting is this part of the above code: $('html, body').stop().animate({ scrollTop: $($anchor.attr('href')).offset().top }, 850,'easeInOutExpo') All I know is that when I remove the above code, my scroll-to links stop working on pages such as these: http://www.northtownsremodeling.com/things-to-know.php You can see the popup error happen and stay in the console easily by going to a page with a filter like this: http://www.northtownsremodeling.com/bathroom/ And clicking one of the filter buttons. Ultimately, I am trying to make it so my scroll-to setting still works, but not have that error come up anymore. I made this script a long time ago, and I'm really confused as to what could be causing this error when everything is functioning perfectly otherwise? Thanks!

  • Looping through array values using JQuery and show them on separate lines

    - by user3192948
    I'm building a simple shopping cart where visitors can select a few items they want, click on the "Next" button, and see the confirmation list of things they just selected. I would like to have the confirmation list shown on each line for each item selected. HTML selection <div id="c_b"> <input type="checkbox" value="razor brand new razor that everyone loves, price at $.99" checked> <input type="checkbox" value="soap used soap for a nice public shower, good for your homies, price at $.99" checked> <input type="checkbox" value="manpacks ultimate choice, all in 1, price at $99"> </div> <button type='button' id='confirm'>Next</button> HTML confirmation list <div id='confirmation_list' style='display:none;'> <h2>You have selected item 1</h2> <h2>Your have selected item 2 </h2> </div> JS $(function(){ $('#confirm').click(function(){ var val = []; $(':checkbox:checked').each(function(i){ val[i] = $(this).val(); }); }); }); I ultimately want to replace the words 'Your have selected item 2' in h2s with the values selected from each check box. With the code above I'm able to collect the values of each checkbox into an array val, but having difficulty looping through and displaying them. Any advice would be appreciated.

  • Can't push to git hub

    - by John
    I just completed chapter one of the Ruby on Rails Tutorial by Hartl. Posted about one minor hitch previously. Now I started chapter two. I swear I did everything by the book, but now when I try: git push -u origin master I get the following messages after entering my passphrase: ERROR: repository not found fatal: could not read from remote repository Please make sure you have the correct access rights and that the repository exists. When I down loaded heroku tools I think it installed a second version of ruby on my machine. In any case I now have two version listed under All Programs. Could this have screwed thing up? The two versions are Ruby 1.9.2-p290 and 1.9.3-p327. Also when I open the command prompt using 1.9.2 there is a wierd thing at the top before I do anything: 'C:\Program' is not recognized as an internal or external command, operable program or batch file. This is then followed by the normal prompt on the next line. I'm wondering if the use of my public keys have some how gotten screwed up. Any help would be appreciated.

  • Accessing global variables in a flash[:notice]

    - by Trip
    This is deals_controller.rb. And it works like this, except two things. Not sure how to call Deal.count to add in my flash[:notice] . I get the hunch that its not calling something global. I need that contional statement back, as I'm pretty sure its responsible for actually adding the new @deal . So I assume my syntax is off. Do note, I added an extra 'end' when I uncomment this block. def create -# This will use the disclaimer_ids submitted from the check boxes in the view -# to add/delete deal.disclaimers entries to matched the list of checked boxes. @deal = Deal.new(params[:deal]) -# <------I Need this commented out IF statement back ------- -#if @deal.valid? && @organization.deals << @deal flash[:notice] = 'Your promotion is published! You may find it in the number 1 position of our #{deal.count} previously posted promotions. To see your promotion, click here."' respond_to do |format| format.html { redirect_to organization_deals_path(@organization) } format.js -# I Need this IF Statement Back! -#else -#@disclaimers = Disclaimer.all -#render :action = 'new' end end Thanks!

  • Alert Box Methods

    - by Vecta
    I just need a little advice on what may be the best method for handling my situation. I'm in need of placing three buttons in the sidebar of the website I maintain. The website is massive and hard to handle. Currently, it's all HTML files (there are over 10,000 of them believe it or not). We're transitioning to a database website so I don't want to make any sweeping changes that are site-wide, as they may just be scrapped in our re-design process in coming months. However, these buttons are for an application process. When you click on them, an alert box will need to pop up to give you a bit of information and they either allow you to cancel the action or proceed. The buttons are currently located in the left nav which is included on every page of the website. Would it be possible to accomplish this using JS or jQuery? I'd be unable to easily add scripts into the tags on all of the applicable pages, but I'd like to avoid the browser driven "http://www...Says: blah blah" message if possible. Any insight is greatly appreciated! Thank you!

    I have a simple question about running some JS in a form i am trying to make it so that if a user selects an option (entry_12) in a drop down list, that the next form fields are not required (entry_11 entry_13 entry_11) those are the IDs for the fields any thoughts? im not sure where to start on this i have searched all over google and cannot find an instance of this. im trying to make it so if a user selects 'check' out of this list <div class="ss-item ss-item-required ss-select"><div class="ss-form-entry"><label class="ss-q-title" for="entry_12">Card Type <span class="ss-required-asterisk">*</span></label> <label class="ss-q-help" for="entry_12"></label> <select name="entry.12.single" id="entry_12"><option value="Check">Check</option> <option value="Mastercard">Mastercard</option> <option value="Visa">Visa</option> <option value="Amex">Amex</option> <option value="Discover">Discover</option></select></div></div></div> that the next fields (cvc code, exp date, cc number) arent required as they are if they had chosen CC

  • Generating dynamic data using Javascript

    - by methuselah
    Given that I have an array of alphabetical characters: var qwerty = [['q', 'w', 'e', 'r', 't', 'y', 'u', 'i', 'o', 'p'], ['a', 's', 'd', 'f', 'g', 'h', 'j', 'k', 'l'], ['z', 'x', 'c', 'v', 'b', 'n', 'm']]; How would I present them in three rows like on a conventional keyboard using JS without resorting to something like this: <input type='button' value='Q' id='bt1'/> <input type='button' value='W' id='bt2'/> <input type='button' value='E' id='bt3'/> <input type='button' value='R' id='bt4'/> <input type='button' value='T' id='bt5'/> <input type='button' value='Y' id='bt5'/> <input type='button' value='U' id='bt7'/> <input type='button' value='I' id='bt8'/> <input type='button' value='O' id='bt9'/> <input type='button' value='P' id='bt10'/> <br> <input type='button' value='A' id='bt11'/> <input type='button' value='S' id='bt12'/> <input type='button' value='D' id='bt13'/> <input type='button' value='F' id='bt14'/> <input type='button' value='G' id='bt15'/> <input type='button' value='H' id='bt16'/> <input type='button' value='J' id='bt17'/> <input type='button' value='K' id='bt18'/> <input type='button' value='L' id='bt19'/> <br /> ...

  • Highlight active form with CSS?

    - by 2unco
    <!doctype html> <html lang="en"> <head> <meta charset="utf-8"/> <style> form:focus{ background:red; } </style> <title>Home, sweet home</title> </head> <body> <form> <input type="text"/> <input type="submit"/> </form> <form> <input type="text"/> <input type="submit"/> </form> <form> <input type="text"/> <input type="submit"/> </form> </body> </html> This obviously doesn't work, as is why I'm asking the question. How can I get the form which has one if it's inputs as the focus to highlight? That is, I want to be able to apply styles to the active FORM, not the active INPUT - is that doable without JS or something?

  • Keeping a web app project organized?

    - by user246114
    Hi, I'm writing a web app, using jsp to create the page content. I need a pretty good amount of javascript to make the app work. Does anyone have any recommendations on how to structure my project, such that it doesn't become a mess? This is a broad question, but the basic problem is that I'm insert javascript code directly into my jsp content. Then I might have some external js files. Ids and such are strewn between multiple files. I'm not really sure what a best practice is for keeping this type of project organized. Do you always keep your javascript in separate files? There has to be a few hooks in the jsp pages though for them, right? I tried using GWT because I'm really a c/java developer, and I was hoping it would help keep my project more organized (definitely helps) - but GWT is a pain to use with jsp, it really wants you to do all UI generation client side after the page is done loading, doesn't work for what I need to do. Again, broad question, any tips would be great, Thanks

  • jQuery validation plugin: valid() does not work with remote validation ?

    - by a-dilla
    I got started by following this awesome tutorial, but wanted to do the validation on on keyup and place my errors somewhere else. The remote validation shows its own error message at the appropriate times, making me think I had it working. But if I ask specifically if a field with remote validation is valid, it says no, actually, its not. In application.js I have this... $("#new_user").validate({ rules: { "user[login]": {required: true, minlength: 3, remote: "/live_validations/check_login"}, }, messages: { "user[login]": {required: " ", minlength: " ", remote: " "}, } }); $("#user_login").keyup(function(){ if($(this).valid()){ $(this).siblings(".feedback").html("0"); }else{ $(this).siblings(".feedback").html("1"); } }) And then this in the rails app... def check_login @user = User.find_by_login(params[:user][:login]) respond_to do |format| format.json { render :json => @user ? "false" : "true" } end end I think that my problem might have everything to do with this ticket over at jQuery, and tried to implement that code, but, being new to jQuery, it's all a bit over my head. When I say bit, I mean way way. Any ideas to fix it, or a new way to look at it, would be a big help.

  • Radiobutton validation.

    - by _sh
    The question is on the client side validation using java script. Significant parts of the program related to the question are given below.. ... <form name="results" action="" method="post"> ... <input type="radio" name="id" value="<%= id_edit %>" /> <!-- Don't bother about id_edit --> .... <input type="button" name="Edit" value="Edit" onclick="invoke(0)"><input type="button" name="Delete" value="Delete" onclick="return invoke(1)"> .... The script, function invoke(btn) { if(btn == 0) document.results.action="gev.do"; if(btn == 1) document.results.action="del.do"; document.results.submit(); } What basically i do is, depending on the selection of button, i pass a value to the servlet, either for updation or deletion. My question is, how can i validate the radiobutton, ie, i can any one help me out writing the js to validate if any one of the radio button is selected. All my efforts are in vein and i now use server side validation.

  • C# Basic Multi-Threading Question: Call Method on Thread A from Thread B (Thread B started from Thre

    - by Nick
    What is the best way to accomplish this: The main thread (Thread A) creates two other threads (Thread B and Thread C). Threads B and C do heavy disk I/O and eventually need to pass in resources they created to Thread A to then call a method in an external DLL file which requires the thread that created it to be called correctly so only Thread A can call it. The only other time I ever used threads was in a Windows Forms application, and the invoke methods were just what I needed. This program does not use Windows Forms, and as such there are no Control.Invoke methods to use. I have noticed in my testing that if a variable is created in Thread A, I have no trouble accessing and modifying it from Thread B/C which seems very wrong to me. With Winforms, I was sure it threw errors for trying to access things created on other threads. I know it is unsafe to change things from multiple threads, but I really hoped .NET would forbid it altogether to ensure safe coding. Does .NET do this, and I am just missing the boat, or does it only do it with WinForm apps? Since it does seemingly allow this, do I do something like an OS would do, create a flag and monitor it from Thread A to see if it changes. If it does, then call the method. Doesnt the event handler essentially do this, so could an event be used somehow called on the main thread?

  • Doing a DELETE request from <a> tag without constructing forms?

    - by Mike Trpcic
    Is there any way to force an <a href> to do a delete request when clicked instead of a regular GET? The "Rails" way is to dynamically generate a <form> tag that adds the appropriate params so that it gets routed to the right place, however I'm not too fond of that much DOM manipulation for such a simple task. I thought about going the route of something like: $("a.delete").click(function(){ var do_refresh = false; $.ajax({ type: "DELETE", url: "my/path/to/delete", success: function(){ do_refresh = true; }, failure: function(){ alert("There is an error"); } }); return do_return; //If this is false, no refresh would happen. If it //is true, it will do a page refresh. }); I'm not sure if the above AJAX stuff will work, as it's just theoretical. Is there any way to go about this? Note: Please don't recommend that I use the rails :method => :delete on link_to, as I'm trying to get away from using the rails helpers in many senses as they pollute your DOM with obtrusive javascript. I'd like this solution to be put in an external JS file and be included as needed.

  • Get real height of div plus css generated content (if possible)

    - by qp2wd
    I'm trying to use javascript to give three divs a negative top position equal to their height. I've got it working, sort of (thanks to help from here!) but instead of calculating the height of each div and calculating the top position accordingly, each div is being assigned a negative top position of -367px: <script type="text/javascript"> $(document).ready(function() { //Get height of footer popup var pHeight = $('footer ul li > ul').outerHeight(); //Calculate new top position based on footer popup height var nHeight = pHeight + "px"; $('footer ul li > ul').css({ //Change top position to equal height of footer popup 'top' : "-" + nHeight }); }); </script> I've tried this using .height, .outerheight, and even .getheight which someone mentioned on the Jquery documentation for .height. I also tried using an each statement, though it didn't seem to work; I may have written it incorrectly. In addition (if possible), I'd like the negative position to take into account the height of a content being generated using the css :after psuedo-property, though I can always manually add that in to the calculation if javascript has no way to access that. EDIT: Added a test page link. It's the bottom divs I'm trying to target with JS, but if anyone has an idea regarding how to fix the problem with the top divs I'd be much obliged as well. http://www.qualityprinters2.com/test/float-tab-test.html

  • How to get jquery to append output immediately after each ajax call in a loop

    - by david_nash
    I'd like to append to an element and have it update immediately. console.log() shows the data as expected but append() does nothing until the for loop has finished and then writes it all at once. index.html: ... <body> <p>Page loaded.</p> <p>Data:</p> <div id="Data"></div> </body> test.js: $(document).ready(function() { for( var i=0; i<5; i++ ) { $.ajax({ async: false, url: 'server.php', success: function(r) { console.log(r); //this works $('#Data').append(r); //this happens all at once } }); } }); server.php: <?php sleep(1); echo time()."<br />"; ?> The page doesn't even render until after the for loop is complete. Shouldn't it at least render the HTML first before running the javascript?

  • Aborting $.post() / responsive search results

    - by Emphram Stavanger
    I have the following kludgey code; HTML <input type="search" id="search_box" /> <div id="search_results"></div> JS var search_timeout, search_xhr; $("#search_box").bind("textchange", function(){ clearTimeout(search_timeout); search_xhr.abort(); search_term = $(this).val(); search_results = $("#search_results"); if(search_term == "") { if(search_results.is(":visible")) search_results.stop().hide("blind", 200); } else { if(search_results.is(":hidden")) search_results.stop().show("blind", 200); } search_timeout = setTimeout(function () { search_xhr = $.post("search.php", { q: search_term }, function(data){ search_results.html(data); }); }, 100); }); (uses the textchange plugin by Zurb) The problem I had with my original more simple code was that it was horribly unresponsive. Results would appear seconds later, especially when typed slower, or when Backspace was used, etc. I made all this, and the situation isn't much better. Requests pile up. My original intention is to use .abort() to cancel out whatever previous request is still running as the textchange event is fired again (as per 446594). This doesn't work, as I get repeated errors like this in console; Uncaught TypeError: Cannot call method 'abort' of undefined How can I make .abort() work in my case? Furthermore, is this approach the best way to fetch 'realtime' search results? Much like Facebook's search bar, which gives results as the user types, and seems to be very quick on its feet.

  • Designing an email system to guarantee delivery

    - by GlenH7
    We are looking to expand our use of email for notification purposes. We understand it will generate more inbox volume, but we are being selective about which events we fire notification on in order to keep the signal-to-noise ratio high. The big question we are struggling with is designing a system that guarantees that the email was delivered. If an email isn't delivered, we will consider that an exception event that needs to be investigated. In reality, I say almost guarantees because there aren't any true guarantees with email. We're just looking for a practical solution to making sure the email got there and experiences others have had with the various approaches to guaranteeing delivery. For the TL;DR crowd - how do we go about designing a system to guarantee delivery of emails? What techniques should we consider so we know the emails were delivered? Our biggest area of concern is what techniques to use so that we know when a message is sent out that it either lands in an inbox or it failed and we need to do something else. Additional requirements: We're not at the stage of including an escalation response, but we'll want that in the future or so we think. Most notifications will be internal to our enterprise, but we will have some notifications being sent to external clients. Some of our application is in a hosted environment. We haven't determined if those servers can access our corporate email servers for relaying or if they'll be acting as their own mail servers. Base design / modules (at the moment): A module to assign tracking identification A module to send out emails A module to receive delivery notification (perhaps this is the same as the email module) A module that checks sent messages against delivery notification and alerts on undelivered email. Some references: Atwood: Send some email Email Tracking Some approaches: Request a response (aka read-receipt or Message Disposition Notification). Seems prone to failure since we have cross-compatibility issues due to differing mail servers and software. Return receipt (aka Delivery Status Notification). Not sure if all mail servers honor this request or not Require an action and therefore prove reply. Seems burdensome to force the recipients to perform an additional task not related to resolving the issue. And no, we haven't come up with a way of linking getting the issue fixed to whether or not the email was received. Force a click-through / Other site sign-in. Similar to requiring some sort of action, this seems like an additional burden and will annoy the users. On the other hand, it seems the most likely to guarantee someone received the notification. Hidden image tracking. Not all email providers automatically load the image, and how would we associate the image(s) with the email tracking ID? Outsource delivery. This gets us out of the email business, but goes back to how to guarantee the out-sourcer's receipt and subsequent delivery to the end recipient. As a related concern, there will be an n:n relationship between issue notification and recipients. The 1 issue : n recipients subset isn't as much of a concern although if we had a delivery failure we would want to investigate and fix the core issue. Of bigger concern is n issues : 1 recipient, and we're specifically concerned in making sure that all n issues were received by the recipient. How does forum software or issue tracking software handle this requirement? If a tracking identifier is used, Where is it placed in the email? In the Subject, or the Body?

  • SQLAuthority News – Wireless Router Security and Attached Devices – Complex Password

    - by pinaldave
    In the last four days (April 21-24), I have received calls from friends who told me that they have got strange emails from me. To my surprise, I did not send them any emails. I was not worried until my wife complained that she was not able to find one of the very important folders containing our daughter’s photo that is located in our shared drive. This was alarming in my par, so I started a search around my computer’s folders. Again, please note that I am by no means a security expert. I checked my entire computer with virus and spyware, and strangely, there I found nothing. I tried to think what can cause this happening. I suddenly realized that there was a power outage in my area for about two hours during the days I have mentioned. Back then, my wireless router needed to be reset, and so I did. I had set up my WPA-PSK [TKIP] + WPA2-PSK [AES] very well. My key was very simple ( ‘SQLAuthority1′), and I never thought of changing it. (It is now replaced with a very complex one). While checking the Attached Devices, I found out that there was another very strange computer name and IP attached to my network. And so as soon as I found out that there is strange device attached to my computer, I shutdown my local network. Afterwards, I reconfigured my wireless router with a more complex security key. Since I created the complex password, I noticed that the user is no more connecting to my machine. Subsequently, I figured out that I can also set up Access Control List. I added my networked computer to that list as well. When I tried to connect from an external laptop which was not in the list but with a valid security key, I was not able to access the network, neither able to connect to it. I wasn’t also able to connect using a remote desktop, so I think it was good. If you have received any nasty emails from me (from my gmail account) during the afore-mentioned days, I want to apologize. I am already paying for my negligence of not putting a complex password; by way of losing the important photos of my daughter. I have already checked with my client, whose password I saved in SSMS, so there was no issue at all. In fact, I have decided to never leave any saved password of production server in my SSMS. Here is the tip SQL SERVER – Clear Drop Down List of Recent Connection From SQL Server Management Studio to clean them. I think after doing all this, I am feeling safe right now. However, I believe that safety is an illusion of many times. I need your help and advice if there is anymore I can do to stop unauthorized access. I am seeking advice and help through your comments.

  • DevConnections Slides and Samples Posted

    - by Rick Strahl
    I’ve posted the slides and samples to my DevConnections Sessions for anyone interested. I had a lot of fun with my sessions this time around mainly because the sessions picked were a little off the beaten track (well, the handlers/modules and e-commerce sessions anyway). For those of you that attended I hope you found the sessions useful. For the rest of you – you can check out the slides and samples if you like. Here’s what was covered: Introduction to jQuery with ASP.NET This session covered mostly the client side of jQuery demonstrated on a small sample page with a variety of incrementally built up examples of selection and page manipulation. This session also introduces some of the basics of AJAX communication talking to ASP.NET. When I do this session it never turns out exactly the same way and this time around the examples were on the more basic side and purely done with hands on demonstrations rather than walk throughs of more complex examples. Alas this session always feels like it needs another half an hour to get through the full sortiment of functionality. The slides and samples cover a wider variety of topics and there are many examples that demonstrate more advanced operations like interacting with WCF REST services, using client templating and building rich client only windowed interfaces. Download Low Level ASP.NET: Handlers and Modules This session was a look at the ASP.NET pipeline and it discusses some of the ASP.NET base architecture and key components from HttpRuntime on up through the various modules and handlers that make up the ASP.NET/IIS pipeline. This session is fun as there are a number of cool examples that demonstrate the power and flexibility of ASP.NET, but some of the examples were external and interfacing with other technologies so they’re not actually included in the downloadable samples. However, there are still a few cool ones in there – there’s an image resizing handler, an image overlay module that stamps images with Sample if loaded from a certain folder, an OpenID authentication module (which failed during the demo due to the crappy internet connection at DevConnections this year :-}), Response filtering using a generic filter stream component, a generic error handler and a few others. The slides cover a lot of the ASP.NET pipeline flow and various HttpRuntime components. Download Electronic Payment Processing in ASP.NET Applications This session covered the business end and integration of electronic credit card processing and PayPal. A good part of this session deals with what’s involved in payment processing, getting signed up and who you have to deal with for your merchant account. We then took a look at integration of credit card processing via some generic components provided with the session that allow processing using a unified class interface with specific implementations for several of the most common gateway providers including Authorize.NET, PayFlowPro, LinkPoint, BluePay etc. We also briefly looked at PayPal Classic implementation which provides a quick and cheap if not quite as professional mechanism for taking payments online. The samples provide the Credit Card processing wrappers for the various gateway providers as well as a PayPal helper class to generate the PayPal redirect urls as well as helper code for dealing with IPN callbacks. Download Hope some of you will find the material useful. Enjoy.© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET
