  • Javascript form validation events

    - by user307922
    Hi All, I am making a small form for a php app and had a question regarding javascript validation. What is the best event to run the javascript validation on the input value? Is it the "focusout" event? I used "focusout" to originally but it creates problems when the user hits enter while they are still focused on any particular field in the form. Should I run the js validation when the user clicks submit? Just looking for some advice. Thanks! Chuck

  • javascript object access performance

    - by youdontmeanmuch
    In Javascript, when your getting a property of an object, is there a performance penalty to getting the whole object vs only getting a property of that object? Also Keep in mind I'm not talking about DOM access these are pure simple Javascript objects. For example: Is there some kind of performance difference between the following code: Assumed to be faster but not sure: var length = some.object[key].length; if(length === condition){ // Do something that doesnt need anything inside of some.object[key] } else{ var object = some.object[key]; // Do something that requires stuff inside of some.object[key] } I think this would be slower but not sure if it matters. var object = some.object[key]; if(object.length === condition){ // Do something that doesnt need anything inside of some.object[key] } else{ // Do something that requires stuff inside of some.object[key] }

I'm getting crazy searching functions to do that but now i can't see anyone in Javascript. modified End expected format will be first the next: array[0]='255 250 250 snow (255 250 250)' Then i wanna take it and extract each line into some vars to use them: colour[0]=255; colour[1]=250; colour[2]=250; string=snow (255 250 250); (the vars will be reused with each line)

  • Setting background-image with javascript

    - by Mattoe3k
    In chrome, safari, and opera setting the background image to an absolute reference such as: "/images/image.png" changes it to "http://sitepath/images/image.png". It does not do this in firefox. Is there any way to avoid this behavior, or is it written into the browser's javascript engine? Using jquery to set the background-image also does this problem. The problem is that I am posting the HTML to a php script that needs the urls in this specific format. I know that setting the image path relative fixes this, but I can't do that. The only other alternative would be to use a regexp. to convert the urls. Thanks. Test this in firefox, and chrome / webkit browser: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <div style="height:400px;width:400px;background-image:url(/images/images/logo.gif);"> </div> <br /> <br /> <div id="test" style="height:400px;width:400px;"> </div> <script type="text/javascript" src="/javascripts/jquery.js"></script> <script type="text/javascript"> $(document).ready(function(){ $("#test").css('background-image',"url(/images/images/logo.gif)"); alert(document.getElementById('test').style.backgroundImage); }); </script> </body> </html>

  • javascript button click casuing Internet Explorer secuirty exception...

    - by hp
    Hello, I have a application that allows a user to choose some parameters for a powerpoint report, run the report, then allow the user to "save" or "open" the powerpoint file. I got all of that working OK. When you click on "run" report, it pops open a window which generates the report, stores it in session, then closes the window. I have a button on the main page that will export the report. So, now, when the pop up window that generates the report is finished, i use "window.opener" to call a javascript method on the main page, that will do a javascript click of the button. when this button is pressed, Internet Explorer gives me the following message : "To help protect your security, Internet Explorer blocked this site from downloading files to your computer.." Do you guys know of any tricks around this?

  • Can I pass a string variable into an <a href> tag for a website link?

    - by Joseph
    I am somewhat new to web developing, so I am trying to learn along the way. I have a div that is 500 x 500. Inside of that div I have two divs that are each 250x500. So my outer div is filled up with the two inner divs. I have it setup so that when I click on the first div (the left one) a java script is called, and a prompt pop up box asks for a website URL which is then stored inside of a string variable. How can I make it so that the second div (the right one) takes the string variable from the alert box from the left div and puts it into an a href tag so that I can link to the website from the right div? Can a a href tag accept a value from a variable for its link? Maybe I am going about this all wrong, is there a better way I should be approaching this? Any help is appreciated!!

  • Using Selenium-IDE with a rich Javascript application?

    - by Darien
    Problem At my workplace, we're trying to find the best way to create automated-tests for an almost wholly javascript-driven intranet application. Right now we're stuck trying to find a good tradeoff between: Application code in reusable and nest-able GUI components. Tests which are easily created by the testing team Tests which can be recorded once and then automated Tests which do not break after small cosmetic changes to the site XPath expressions (or other possible expressions, like jQuery selectors) naively generated from Selenium-IDE are often non-repeatable and very fragile. Conversely, having the JS code generate special unique ID values for every important DOM-element on the page... well, that is its own headache, complicated by re-usable GUI components and IDs needing to be consistent when the test is re-run. What successes have other people had with this kind of thing? How do you do automated application-level testing of a rich JS interface? Limitations We are using JavascriptMVC 2.0, hopefully 3.0 soon so that we can upgrade to jQuery 1.4.x. The test-making folks are mostly trained to use Selenium IDE to directly record things. The test leads would prefer a page-unique HTML ID on each clickable element on the page... Training the testers to write or alter special expressions (such as telling them which HTML class-names are important branching points) is a no-go. We try to make re-usable javascript components, but this means very few GUI components can treat themselves (or what they contain) as unique. Some of our components already use HTML ID values in their operation. I'd like to avoid doing this anyway, but it complicates the idea of ID-based testing. It may be possible to add custom facilities (like a locator-builder or new locator method) to the Selenium-IDE installation testers use. Almost everything that goes on occurs within a single "page load" from a conventional browser perspective, even when items are saved Current thoughts I'm considering a system where a custom locator-builder (javascript code) for Selenium-IDE will talk with our application code as the tester is recording. In this way, our application becomes partially responsible for generating a mostly-flexible expression (XPath or jQuery) for any given DOM element. While this can avoid requiring more training for testers, I worry it may be over-thinking things.

  • Determine if javascript has completed.

    - by Duracell
    My question is somewhat similar to this one. We want to know if there's a way to determine if all javascript has completed (so no javascript is running). We have a lot of stuff that runs on a timeout after the page's onload event, so even after the page is loading, stuff could be happening for a few seconds. For a whole bunch of reasons, mostly relating to requirements from management, we need to know when all of these scripts have finished running. There's an arbitrary number of them so a general solution would be great.

  • javascript - how to call a function newly added from ajax

    - by strike_noir
    I have a coding difficulty which have been asked in this forum before: Calling a JavaScript function returned from a Ajax response But I didn't find the answers quite satisfying. To be more precise of the problem I'm dealing, here is the details: I dynamically load a document (HTML and javascript) using jquery var url = 'document.php'; $('#container').load(url); And then I want to call the functions from that document.php. Due to my requirement, I don't want to call the function after the documents' loaded, but rather to call it later when I need it. Because it was dynamically loaded, the DOM doesn't recognize the functions. How to properly call this function? Thank you

  • How do i translate this to "simpler" JavaScript?

    - by Julian Weimer
    Since i'm working with Titanium i realzed that its current JavaScript Interpreter doesn't accept specific coding-styles. So for for-loops and if-statements i have to have braces, even though i only want to span one line. Furthermore there is more i have to change if i want to use a Javascript Library like underscore.js. This is what Titanium doesn't want to see: if (!(result = result && iterator.call(context, value, index, list))) {_.breakLoop();} if (nativeSome && obj.some === nativeSome) {return obj.some(iterator, context);} var computed = iterator ? iterator.call(context, value, index, list) : value; computed >= result.computed && (result = {value : value, computed : computed}); Can i use a simpler syntax to describe the logic behind those lines of code?

  • Ensuring Updated CSS/JavaScript on Client Side

    - by Alex
    I'm trying to ensure that visitors of my ASP.NET MVC website always have the most-current CSS and Javascript (and not some older cached version). I tried to realize this by generating a seed value when the application domain starts, and automatically append it to the CSS and Javascript URLs (so now instead of /Content/All.js the link is /Content/All.js?549238 etc.). Unfortunately I just found out by debugging via Firebug that this causes now a full download request every time (the new "seeded" response is no longer cached at all, but I only wanted the first check to download the 'updated' version, but then cache again/only check if there is a difference). How can I achieve my goal, is there a better way of doing this? I need the client to always request the newest version, but then cache if no change happened. Edit: This appears to be related to the fact that my page is served over SSL. I asked a follow up question here regarding enabling clientside caching with SSL.

  • Issue with blocking the UI during a onchange request - prevents other event from firing.

    - by jfrobishow
    I am having issues with jQuery blockUI plugins and firing two events that are (I think, unless I am loosing it) unrelated. Basically I have textboxes with onchange events bound to them. The event is responsible for blocking the UI, doing the ajax call and on success unblocking the UI. The ajax is saving the text in memory. The other control is a button with on onclick event which also block the UI, fire an ajax request saving what's in memory to the database and on success unblock the UI. Both of these work fine separately. The issue arise when I trigger the onchange by clicking on the button. Then only the onchange is fired and the onclick is ignored. I can change the text in the checkbox, click on the link and IF jQuery.blockUI() is present the onchange alone is fired and the save is never called. If I remove the blockUI both function are called. Here's a fully working example where you can see the issue. Please note the setTimeout are there when I was trying to simulate the ajax delay but the issue is happening without it. <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script src="http://github.com/malsup/blockui/raw/master/jquery.blockUI.js?v2.31"></script> <script> function doSomething(){ $.blockUI(); alert("doing something"); //setTimeout(function(){ $.unblockUI(); //},500); } function save(){ $.blockUI(); //setTimeout(function(){ alert("saving"); $.unblockUI(); //}, 1000); } </script> </head> <body> <input type="text" onchange="doSomething();"> <a href="#" onclick="save()">save</a> </body> </html>
