  • Adding links to this PHP statement

    - by poindexter
    Here is a PHP statement that basically sets off a javascript image slider. Only problem is I can't figure out how to get each individual image to a link to a different page. Any tips or suggestions? I appreciate it! <?php jsbrotate('height=316&width=924&imgdisp=4&imgfade=2&images=/wp-content/uploads/image_1_linked.png|/wp-content/uploads/image_2.png|/wp-content/uploads/image_3.png|/wp-content/uploads/image_4.png|/wp-content/uploads/image_5.png'); ?>

  • Build a Sitemap but webpages don't use links

    - by THX1138.6
    Folks I am trying to build a sitemap (we need one badly) for a huge multi-page web app. Technically its not much more than a collection of php/MySQL web forms that use javascript instead of traditional linkage to access the many pages. >td width="100" align="center" ONMOUSEOVER="this.className='bgover'" ONMOUSEOUT="this.className='bgout'" onclick="location.href='../main.php'">Main Page</td> Above is code sample of how the links are currently managed. I know I can search through the various pages, nearly a 1000, and find these "location.href" variables and that will help me a sitemap for each section. But maybe there is an easier way? WE use Trac and SVN so perhaps I am going about this the wrong way? Any advice would be appreciated.

  • any ideas for avoiding duplicate code in C# and javascript

    - by ooo
    i have an asp.net mvc website where i build up most of the page using C# for example building up html tables given a set of data from my viewmodel i also have a lot of javascript that then dynamcially modifies these tables (add row for example). the javascript code to add a new row looks extremely similar to my "rendering" code i have in C# that is used to build up the html table in the first place. Every time i change the c# code to a add a new field, i have to remember to go back to the javascript code to do the same. is there a better way here?

  • Preloading images in HTML, is there a more modern way?

    - by John
    I have an image loaded by JS on a mouse event. It's a fairly big image so I want to make sure it gets pre-loaded. I reemmber some old techniques from years ago and found this example: <SCRIPT LANGUAGE = JAVASCRIPT> if (document.images) { img1 = new Image(); img2 = new Image(); img1.src = "imageName1.gif"; img2.src = "imageName2.gif" } </SCRIPT> I wondered if this is still good/relevant, or maybe browsers automatically detect unused images and preload them anyway? Note my page has to support IE6, so I might still need older techniques anyway, but I'm still interested if more modern browsers have a better way?

  • How to stop a Timer-X timer (jQuery)

    - by Damien K.
    I'm using Timer-X's timerDelayCall function in order to have a repeating rotator on my page, which starts automatically as the page loads: jQuery.timerDelayCall({ interval: 2000, repeat: true, callback: function(timer) { ... (my rotator logic here) } } }); The problem is that I'm trying to make a function that includes stopping that timer: function signUp() { ... (timer stop code here) } The documentation stats that timer.stop() does that, but however I format it, I get errors about it not being declared. I have tried every variation I can think of, such as: timer.stop(); jQuery.timer.stop(); $(document).timer.stop(); jQuery.timerDelayCall({ callback: function(timer) { timer.stop() } }); I'm sure I'm missing something simple - I come from a PHP background yet I'm new to javascript - but can't see what it is exactly. Help is much appreciated!

  • Bind event to shape on canvas

    - by Ben Shelock
    How can I bind an event to a shape drawn on a canvas? I presumed this would work but I get an error. <html> <head> <script type="application/javascript"> function draw() { var canvas = document.getElementById("canvas"); var ctx = canvas.getContext("2d"); ctx.fillStyle = "rgb(200,0,0)"; var rec = ctx.fillRect (0, 0, 55, 50); rec.onclick = function(){ alert('something'); } } </script> </head> <body onLoad="draw()"> <canvas id="canvas" width="300" height="300"></canvas> </body> </html>

  • .click() callback references local variable from the calling method instead of copying by value

    - by Eric Freese
    The following jQuery Javascript code is included on an otherwise empty page. $(function() { for (var i = 0; i < 10; i++) { element = $('<div>' + i + '</div>'); element.click(function() { alert(i); }); $('body').append(element); } }); The desired behavior is that this code should generate 10 div elements numbered from 0 to 9. When you click on a div element, an alert popup will show the number of the div element you clicked on (i.e. if a user clicks on the div element labeled '4', the alert popup should show the number 4). The alert popup instead shows the number 10 regardless of which div element is clicked on. How can I modify this code to make it behave in the desired way?

  • jQuery pagination go to page on input value change

    - by JV10
    I'm creating some pagination for my website, and want to use an input-element to navigate between pages. Like the following example: The input would require the "return" key to be hit for the script to trigger. If the value entered is not within range and alert would trigger. e.g. If there was 32 pages, "Please enter a value between 1 and 32" Can this be done using jQuery or javascript, by detecting the value change within the range of pages and redirecting to that page? I'm trying to create the same device on Getty Images: http://www.gettyimages.com.au/Search/Search.aspx?contractUrl=2&language=en-US&family=creative&p=ball&assetType=image&clarification=ball%3A60847

  • What's the best way to debug AJAX to PHP calls?

    - by Jascha
    I'm having a miserable time debugging one small function on my new project. Essentially I'm having a user log out via an AJAX call to my log out script on my server called "userfFunctions.php" I'm using AJAX so that I don't have the headache of writing more regex to match my mod_rewrites. Anyway, every so often, it seems as though my Post data just flat out dies and since the PHP is running behind the scenes, I feel like I have no way of finding out where the data flow is being disrupted. BTW This function works 19 hrs of the day. Here is the javascript function: function logOut(){ var data = new Object; data.log_out = true; $.ajax({ type: 'POST', url: 'http://www.mydomain.com/User_Validator', //<-- redirects to userFunctions.php data: data, success: function(data) { alert(data); // <-- a response is triggered but with no response data! } }); } the php side: if(isset($_POST['log_out'])){ echo 'alert this!'; } here is my awesome response:

  • Form variable does not refresh with ajax call

    - by ChrisOPeterson
    I'm building a simple email sending form and wanted to make it with ajax. The form submits correctly the first time but if you make any subsequent changes to the text in the form and then submit again then jquery does not pick up on the changes and posts the old data. Whats going on? <script type="text/javascript"> var $j = jQuery.noConflict(); $j(document).ready(function() { var submit_url = "mail_submit.php"; var send_email = $j("#sendemail"); send_email.click(function() { var form = $j("#post"); $j.post(submit_url, form.serialize(), function(data) { alert(data); }); }); });

  • display text when image on-click/hide text when different image click

    - by Jonah1289
    Hi I have created the following effects on the images seen here http://techavid.com/design/test3.html . You see when you hover and then click on each image, they go from grey to color. When you click on one - the others go grey and the one clicked remains color. That's cool, but now I need the text 1st: Sun for example to display and hide along with its graphic button. The word "Sun," is a link that needs to link out to a URL so it has to be separated from the image effect code. What jquery or javascript code do I need to do this? thanks, jonah p.s. How do i properly post the code I have now. I tried to paste code in "enter code here," but received errors - thnx

  • .net MVC, dealing with json and Areas

    - by JoseMarmolejos
    When not using areas dealing with the url for the JsonResults from the clientside is not much of a pain, usually you can get away with hardcoding the url into your json calls and get away with it. Problem arises when you have different areas and you don't want to update all your links when you move a controller (and its views) from one area to the other. I'm not very satisfied with the way I'm handling this scenario by having this chunk of code inside every view: <script type="text/javascript"> var ControllerActions = { JsonSearch: '<%= Url.Action("JsonSearch") %>/', JsonDelete: '<%= Url.Action("JsonDelete") %>/', Edit: '<%= Url.Action("Edit") %>/', Delete: '<%= Url.Action("Delete") %>/' } </script> While it does work no matter where I place the views/controllers I wonder if there's a more elegant to do this.

  • How to normalize SVG path data (cross browser)?

    - by Timo
    I have tried to find a way to implement cross browser path normalizer. There IS a native way which is described here and functional example is here, but it works only in newest Opera (but not in IE, FF, Safari, Chrome). The native way uses pathElm.normalizedPathSegList and it converts all relative coordinates to absolute ones and represents all path segment types as a following subset of types: M,L,C,z. I have found only one javascript code and jsfiddled functional example of it, but it works only in IE and FF. Chrome gives "Uncaught Error: INDEX_SIZE_ERR: DOM Exception 1". How this could be fixed to work also in Opera, Safari and Chrome or is there any other way for normalizing SVG paths?

  • Perform function on form submit

    - by flight643
    Hopefully this is a pretty simple question! I've got the code working in jQuery to listen for a specific form on a page to be submitted and perform an alert when it is.. I.e.: The form itself doesn't have a name so I am targetting the form within a specific form ID. $("#content form").submit(function() { alert("lorem ipsum dolor?"); }); What would be the syntax for performing this in javascript alone without using jquery? For example, I have this code (below) and just am unsure of how to listen for the form to be submitted to perform an action.. var submitform = document.getElementById("content").getElementsByTagName("form"); Thanks!

  • jQuery sanitizing comments and linkifying URLs

    - by iWasRobbed
    In terms of jQuery (or Javascript), what happens behind the scenes when a person posts a comment on Facebook, Twitter, or a blog? For instance, do they sanitize the text first, and then pattern match URL's into an actual link? Are there other items of concern that the client-side should check in addition to doing some checks on the backend? I have found a few regex's for turning URL's into links, but I'm not sure if there are better solutions. I'm trying to wrap my head around the problem, but I'm having a difficult time knowing where to start. Any guidance you can provide is greatly appreciated!

    I'm working on a contest where users vote for contestants. Each contestant will have a bio. I was wondering what would be the best way to approach this? Should I do this in php or javascript? Should I use a database to collect data? Should I use sqlite3? If I use sqlite3 how do i install that on my mac? I'm very new to all this but I'm a quick learner. Thanks for any advice.

  • Malware on a client's website - Ideas?

    - by Jeriko
    We recently got a call from one of our clients, complaining that their site has some "strange looking code" at the bottom of the page. We checked out the source code, and discovered that about 800 bytes of malicious javascript code had been appended to the templates/master file, after the </html> tag. I won't post said code because it looked particularly nasty. As far as I can tell, there would be no way for this file to be edited in any way, unless someone had direct access to the server and/or FTP login details. The actual file itself has been modified, so that rules out any kind of SQL attack. Besides a person physically gaining credentials and hand-modifying this file, would there be any other logical explaination for what happened? Has anyone else had experience with something like this happening?

  • Looking for a specific kind of WEB framework, no malarkey please

    - by Hello you all men
    We do maintenence on a number of systems. I'm finally in a place where I'm teh fucking boss for once, and have to design a large system that will have a long maintenance contract. There's a couple of tasks I find myself always repeating: 1) similar tasks for users with JS and those without 2) similar things for contents and rss/atom feeds, etc. To combat these I will need appropriate handling of assets (think JS files, CSS, themes/templates, etc.), excellent auth/user systems, javascript/ajax forethought, appropriate model setups. Codeigniter fails on many of these. Basically, with enough time I could build this system with Zend, but I'm curious what else is out there as Zend is also kind of a heavy-weight. We need something that is Rapid but maintainable, CodeIgniter is not maintainable. We will have a lot of AJAX APIs in place for the design team to play with. At first I thought jQuery was cool, but now I'm looking at Dojo.

  • [Ext.tree.TreePanel] getNodeById does not work

  • How to implement a book preview (2 page spread) without using Flash?

    - by littlejim84
    I'm looking into a solution for work, where you have a two page spread of the book to preview. Either side of this, you can hover in the corner to create a pseudo-flip and then click the mouse button to actually turn the page. I know there is many Flash solutions out there, but in this case we cannot use it... So we are looking for a possible solution that can work across all major browsers (yes, including IE6)... I looked a few canvas solutions, but with Google's canvas extension for IE, these will terribly slow. So was thinking about an SVG/VML solution, like Raphael Javascript library. This could be good, but then trying to look into how to code this, without examples, could be a challenge with the time constraint. Is there a solution out there that fits (or almost fits) this problem?

  • Image Replacement (JS/JQuery) working in IE but not FF

    - by Sunburnt Ginger
    I have tried multiple solutions for replacing broken images (both JS & jQuery) and all work perfectly with IE but not in FF, is there a reason for this? Are images handled differently in FF that may cause this? JQuery Example: $("img").error(function(){ $(this).unbind("error").attr("src", "nopic.jpg"); }); Javascript Example: (triggered by onError event in img tag) function noimage(img){ img.onerror=""; img.src="nopic.jpg"; return true; } Both of these examples work perfectly in IE but not at all in FF. What gives? Thanks in advance!
