  • Is strict mode more performant?

    - by sje397
    Does executing javascript within a browser in 'strict mode' make it more performant, in general? Do any of the major browsers do additional optimisation or use any other techniques that will improve performance in strict mode? Edit: Since none of the major engines actually implement strict mode, I'll rephrase slightly: Is strict mode intended, amongst its other goals, to allow browsers to introduce additional optimisations or other performance enhancements?

  • Bind event to a div appearing

    - by AndyC
    Can I create an event so I can execute some javascript whenever an element with a specific ID becomes visible or appears on the page? The element comes from a remote resource (so isn't in MY html code but appears on page load) and I'd like some code to run when it appears (and only if it appears, it may not appear every load). Thanks!

  • From client, force whole page validation

    - by George
    I have an ASP button for which I have set the OnClientClick property to display a javascript confirm message. However, I only want this message to be displayed AFTER all of the client side validations have passed. How can I do this? Essentially, I believe that I need to force Page level validation from the client and then, only if it passes, display the confirmation box.

  • style a navigation link when a particular div is shown

    - by Matt Meadows
    I have JQuery working to show a particular div when a certain link is clicked. I have managed to apply the effect I'm after with the main navigation bar through id'ing the body tag and using css to style when the id is found. However, i'd like to apply the same effect to the sub navigation when a certain div is present. How the main navigation is styled: HTML: <nav> <ul> <li id="nav-home"><a href="index.html">Home</a></li> <li id="nav-showreel"><a href="showreel.html">Showreel</a></li> <li id="nav-portfolio"><a href="portfolio.html">Portfolio</a></li> <li>Contact</li> </ul> </nav> CSS: body#home li#nav-home, body#portfolio li#nav-portfolio { background: url("Images/Nav_Underline.png") no-repeat; background-position: center bottom; color: white; } (Other links havent been added to styling as those pages are still in development) How the sub navigation is structured: <nav id="portfolioNav"> <ul> <li id="portfolio-compositing"><a id="compositingWork" href="#">Compositing</a></li> <li id="portfolio-animation"><a id="animationWork" href="#">Animation</a></li> <li id="portfolio-motionGfx"><a id="GFXWork" href="#">Motion Graphics</a></li> <li id="portfolio-3D"><a id="3DWork" href="#">3D</a></li> </ul> </nav> As you can see, its similar format to the main navigation, however i've tried the same approach and it doesn't work :( The Javascript that switches the divs on the navigation click: <script type="text/javascript"> $(document).ready(function() { $('#3DWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #Portfolio3D'); }); $('#GFXWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #motionGraphics'); }); $('#compositingWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #PortfolioCompositing'); }); $('#animationWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #PortfolioAnimation'); }); }); </script> JSFiddle for full HTML & CSS : JSFiddle File The effect I'm After:

  • Why does isNaN(123.) return false?

    - by vivekraman
    Hi, Why does the Javascript function call isNaN(123.) return false? Is this a universally acceptable number or will it cause errors downstream? I'm validating whether a value is a valid decimal using isNaN along with split. Are there cross-browser issues with isNaN? Should I use a bespoke implementation? Thanks.

  • Passing arguments to a function?

    - by dfjhdfjhdf
    I need to learn how to pass an associative array to a function so that I could do the following within the function: function someName($argums) { if (gettype($argums) != 'array' || !array_key_exists('myOneKey', $argums) || !array_key_exists('myOtherKey', $argums)) { return false; } /*do other stuff*/ } (That's how I would do in PHP what I am looking for in JavaScript.)

    - by AGoodDisplayName
    We used to be able to use javascript in IE to produce a chromeless window...no buttons, scrollbars or even the standard edges of the browser window. My question: Is there any way to accomplish this type of window look from the web with today's browsers?

  • Have a child window be notified when parent window goes to a different page?

    - by Heinrich Schmetterling
    i have a parent window and a child window. in javascript, i want a function in child window to be called whenever the parent window loads a new page. i'd like to use something similar to jQuery's $(document).ready() so that I don't have to worry about whether the parent is done loading yet - but ready() only appears to fire when the window loads the first page - but not when, say, a link is clicked in the parent and it loads a second page. any suggestions? thanks.

  • Detect End of Video Playback in Web Page

    - by Eric J.
    Is there a widely supported video playback technology for web pages that provides an event/hook that can be captured from Javascript when playback reaches the end of the stream? My goal is to provide a web page that plays a video and then asks the user a question about the video once playback is complete. The question would be hidden or disabled until they have actually viewed the video.

    - by IL CARTOLAiO
    Hi all, I have a javascript that dynamically creates many <img> tags, and appends them to various divs. I want to prevent these images from wrapping; when the screen resolution is not enough to contain them the browser should create horizontal scroll-bars. Sorry for this bad English.
