  • How do I stop a jquery animation based on CSS values?

    - by kevn
    So, I have two divs: #div1 and #div2. I want '#div2' to disappear when '#div1' has the CSS value: top = 0px. Here is the CSS: #div1 { top: 0px; } #div2 { display: block; } if ( $('#div1').css('top') == '0px' ) { $("#div2").hide(); } else { $("div2").fadeIn(); } $("div2").click(function(){ $("#div1").animate({top:"+=315px"}, "slow"); }); The problem I am running into is that I'm changing that CSS value (for #div1) via Javascript and for this reason, my js doesn't acknowledge the change and doesn't make the div disappear (I think). Is there any way to make #div2 disappear when #div1's CSS property top = 0 and reappear whenever it is changed? Or is there a better way to implement this?

  • Debugging PHP in Aptana 2.0

    - by Nick Lowman
    I'm a real newbie when it comes to PHP debugging so forgive my stupidity. I have a simple html form that submits to a PHP script and I want to debug that script and see what's being sent from the form. My Aptana has two two PHP interpreters installed; Zend Debugger on port 10001 and XDebug on 9000 I have the Firefox Aptana Addon installed I have my HTML page on the following url, running locally; http://3i/latest.html In the IDE I open the PHP script and add some breakpoints, I then open the latest.html and I click on the debug button. It launches the HTML page in a local webserver running at; http://127.0.0.1:8000/3i/latest.html I then fill out the form and submit at which point the debugger tells me the JS Debugger has terminated but it doesn't stop at my break points. I've had a good read around and I can't find anything which helps me, which makes me think it's something pretty easy and I'm being a bit dumb.

  • server side of adsense

    - by dole
    Hi there Google ask you to add a javascript code to your page and it will generate the links. The script has some id which are sent to the server, but I don't know how. <script type="text/javascript"><!-- google_ad_client = "ca-pub-1234567890123456"; /* snipet_name */ google_ad_slot = "123456789"; google_ad_width = 728; google_ad_height = 90; //--></script><script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script> I'm curious to know how the client and slot ids are send to the server. Javascript is client side and I wish to know how those parameters are sent to the server in order to query a db and to return the links. A link, sample, explanation related to PHP will work great for me. TY

  • running code when two events have triggered

    - by Evert
    This is mostly a language-agnostic question. If I'm waiting for two events to complete (say, two IO events or http requests), what is the best pattern to deal with this. One thing I can think of is the following (pseudo js example). request1.onComplete = function() { req1Completed = true; eventsCompleted(); } request2.onComplete = function() { req2Completed = true; eventsCompleted(); } eventsCompleted = function() { if (!req1Completed || !req2Completed) return; // do stuff } Is this the most effective pattern, or are there more elegant ways to solve this issue?

  • Why call iframe from javascript

    - by sammville
    I want to know why some ad codes or embed codes don't directly give you iframe code to embed on your site instead they give a javascript code which links to another javascript file on their server. The file on their server calls the iframe which serves the content. Why is this done and what are the benefits of this method. Example: this is the code issued by amazon: <script type="text/javascript" src="http://www.assoc-amazon.co.uk/s/ads.js"></script> Which opens another javascript file that calls the iframe.

  • requireJS : How to structure Javascript for an entire site?

    - by pagewil
    I have 3000+ lines of javascript that I need to get into a sensible/maintainable structure. I have chosen to use requireJS as it has been recommend to me by a few people. I have a bunch of variables that are used throughout the application and need to be available everywhere. I also have a bunch of functions that need to be available everywhere. Apart from these two dependencies most of the code can be divided off into their own modules. I am having trouble understanding how to manage my main variables so that if one module of code makes changes to the variables the rest of the JS modules will see that change. I think I need to see a few examples that demonstrate how requireJS is intended to work on a larger scale that the examples in the documentation. If anyone is an experienced requireJS user I would love the hear your tips!

  • Process AJAX response with long runing tasks

    - by mpz
    I have long time task in controller action. I use delayed job for it. (Also in heroku it is good practice for perfomance - dyno must work for small time in each request) But my client need result of it work and users can wait on that task. It is more clear: no any addition models or records in it, simple view and js... I think about such way: On client run AJAX with very long timeout (5 min for example) Client make request to server as usual On controller in action1 def start_work (with delay work setup) i need NO any response to client After work performs (delay job finished) i need run new action2 with response to client Client recieve response after about 1-5 min It is possible?

  • How to write a program that mimics Fiddler by using tcpdump or from scratch?

    - by ????
    When Fiddler is not on Mac OS X or Ubuntu, and if we don't install/use Wireshark or any other more heavy duty tools, what is a way to use tcpdump so that 1) It can print out GET /foo/bar HTTP/1.1 [request content in RAW text] [response content in RAW text] POST /foo/... HTTP/1.1 this should be able to be done by tcpdump or by using tcpdump in a short shell script or Ruby / Python / Perl script. 2) Actually, it can be neat if a script can output HTML, with GET /foo/bar HTTP/1.1 POST /foo/... HTTP/1.1 on the page, for any browser to display, and then when clicked on any of those lines, it will expand to show the RAW content like (1) above does. Click again and it will hide the details. The expansion UI can be done using jQuery or any JS library. The script may be short... possibly less than 20 lines? Does anybody know how to do it either for (1) or (2)?

But Its giving me validation error for the Description after the postback. What possible causes?

  • Expression parser library for Android.

    - by Malx
    What is the best way to evaluate simple conditional statements like: "a>b" ? "x-4<10+y & y>x" ? Expressions are loaded from external file. Variables are set in application. Syntax used is not essential. It may be "&" or "and" or any other supported with language/library. I need to take different action depending on result of evaluation - is it true or false. Could I use any parser already included with Andorid? Is there some way to use JS "eval" from browser component? Is it possible to use sqlite expressions to get true/false result without selecting anything? Those libraries are implemented in native code. Will it be faster and less battery expensive?

  • Rails 3: jQuery form not working.

    - by donald
    Hi, I have jquery working on my Rails app using the gem 'jquery-rails'. I also have a search form working correctly. However, when I add :remote => true the form stops working. <%= form_tag services_path, :method => :get, :remote => true do %> <%= text_field_tag :search, params[:search] %> <%= submit_tag "Search", :name => nil %> </div> <% end %> I have also added a index.js.erb but it has no effect on it. For some reason the :remote = true makes the form to stop working. Any reason why? Thanks

  • HTML5 video element non-seekable when using Django development server

    - by Ory Band
    Hey everyone. I've got a Django app serving a webpage with an HTML5 element. There's a wierd "feature", turning the video element to be non-seekable: video.seekable returns a timeRanges object with length=0, whereas it should be length=1. This means I can't edit the video. JavaScript can't do anything either. The thing is, when I upload the problematic webpage, statically - no Django, just plain HTML/JS/CSS - to my website for testing, it works fine - length=1. However, if I try to serve the same static page on my Django dev server still gives the same problem. I am using Django's static serving for dev/debug purposes - Do you have any idea what is causing this, or how can I fix it? Thanks.

  • Specific position for tooltip

    - by Fiona
    Hello, I have a layer which opens up as a tooltip everytime I hover a button. I simply did that by creating a JS function which displays or hides the layer. Now, I am not a pro in JavaScript. My problem is the following: when the button is scrolled towards the top oft he screen I want the tooltip opening below – and if the button is near the bottom of the screen I want the tooltip opening above. Right now I just did it with absolute positioning. But obviously that doesnt do the trick. Who can help? Thanks!

  • How do I bind a click to an anchor without a framework (javascript)

    - by Stomped
    I know this is easily done in jQuery or any other framework, but that's not really the point. How do I go about 'properly' binding a click event in pure javascript? I know how to do it inline (I know this is terrible) <a href="doc.html" onclick="myFunc(); return false">click here</a> and this causes my javascript to execute for a JS enabled browser, and the link to behave normally for those without javascript? Now, how do I do the same thing in a non-inline manner?

  • Embed form in another website - pitfalls

    - by Paddy
    Scenario: We provide a hosted site that clients pay to use internally (a tool to support their business workflow). We have a requirement to provide a form that the clients can 'embed' in their outward facing site. This form will permit a member of the public to enter some details to register an interest - this data will be pushed to our remote system. Question: I'm currently planning on creating a simple HTML page that the client's web guys can include in a simple fashion on their site (either using an iframe or an object tag). If I do this, am I going to run into difficulties when the user tries to submit the embedded form (as it will be going to different domain to the one they are currently browsing)? I had a look at google adsense and I see that they just provide a link to a JS file that renders their ads - I'm not sure I see the advantage in this, but if anybody has any bright ideas... Whatever technique that gets used, I'll have to authenticate the request as coming from my client's site(s).

  • Why repeat database constraints in models?

    - by BWelfel
    In a CakePHP application, for unique constraints that are accounted for in the database, what is the benefit of having the same validation checks in the model? I understand the benefit of having JS validation, but I believe this model validation makes an extra trip to the DB. I am 100% sure that certain validations are made in the DB so the model validation would simply be redundant. The only benefit I see is the app recognizing the mistake and adjusting the view for the user accordingly (repopulating the fields and showing error message on the appropriate field; bettering the ux) but this could be achieved if there was a constraint naming convention and so the app could understand what the problem was with the save (existing method to do this now?)

  • Best way to use the same HTML on static web-pages

    - by John
    If you use dynamic pages like JSP or asp.net, you can have your page template included, and then content added. But what if you have no server-side component and all pages are just HTML/JS? You can of course create a template then copy it for each page, but then if you want to change something you risk having to modify every page, even if you put most styling in CSS properly. Are there any non-awful ways to do this? I could see that an iframe could be used to load the content into the central page but that sounds nasty. Does HTML provide any way to include a base file and add to it?

  • JQuery: Selecting Text in an Element (akin to highlighting with your mouse)

    - by Jason
    I would like to have users click a link that then selects the html text in another element (NOT an input). By "select" I mean the same way you would select text by dragging your mouse over it. This has been a bear to research because everyone talks about "select" or "highlight" in other terms. Is this possible? My code so far is thus: html: <a href="javascript:" onclick="SelectText('xhtml-code')">Select Code</a> <code id="xhtml-code">Some Code here </code> js (jquery): function SelectText(element) { $("#" + element).select(); } but it doesn't work. Am I missing something blatantly obvious? Thanks

  • How can I give some basic text editing functionality to a firefox plugin?

    - by roddik
    Hello. I'm writing a plugin to Firefox, which is basically a sidebar, that is filled with yaml-formatted information based on what user does on the page (just another web testing solution). I want to enable user to change generated text manually right in the sidebar and: Add code-folding (folding click: \n text: some text to a single line) Add highlighting of registered actions (click, fill and so on) and unregistered actions (syntax errors) How do I do that? Is placing an iframe to the sidebar and trying to do that with html/js the best solution (seen it in a similar one)? As you may have noticed, I'm a newbie in plugin writing, so please excuse if anything.

  • Crossplatform development for iPhone & Android

    - by LeonixSolutions
    As far as I can see there doesn't seem to any mature environment for crossplatform development for iPhone & Android slate (but feel free to correct me). I don't know Ipad, I must admit. Any reason why plain Java wouldn't cut it? (maybe underlying things like database (I am not too concerned with hardware)) I am thinking to try to make everything browser based, although that won't get around the d/b & h/w issues, unless there is JS framework that does so. Any advice?

  • Javascript Code For HTML5 Form Validation Not Working

    - by MistUnleashed
    I'm new to JavaScript so I have no idea why this code does not work and validate my HTML5 Form like it should. The JavaScript code which can be found below is supposed to check if the browser supports the required attribute and if it doesn't then it will validate the form and check for any empty spaces. I got the code from this website. In the body of the webpage containing my form I have this: Below is the contactvalidate.js file: $('#formTemplate').submit(function() { if (!attributeSupported("required") || ($.browser.safari)) { $("#formTemplate [required]").each(function(index) { if (!$(this).val()) { alert("Please fill all required fields."); return false; } }); } return false; }); Do I need to change anything in this code or should it work? As I've said I'm new to JavaScript so any help you guys could give me is greatly appreciated.
