  • Javascript / jQuery Exec turns up Null

    - by Matrym
    How do I skip over this next line if it turns out to be null? Currently, it (sometimes) "breaks" and prevents the script from continuing. var title = (/(.*?)<\/title/m).exec(response)[1]; $.get(url, function(response){ var title = (/<title>(.*?)<\/title>/m).exec(response)[1]; if (title == null || title == undefined){ return false; } var words = title.split(' '); $.each(words, function(index, value){ $link.highlight(value + " "); $link.highlight(" " + value); }); });

  • How to switch images with jquery ?

    - by eemceebee
    Hi I have a simple setup with one big image container and 3 smaller thumbnail containers. Now when I click on the thumbnail I want to switch the big image and the small thumbnail image, so that the big image container has now the bigger sized thumbnail and the thumbnail container shows the thumbnail view of the before big image. <div class="thumbnailFloat"> <img src="data/img_2.jpg" width="60" > <img src="data/img_3.jpg" width="60" > <img src="data/img_4.jpg" width="60" > </div> <div class="imageFloat"> <img src="data/img_1.jpg" width="180" height="250"> </div> Thanks for helping out.

    This is my usual way to debug javascript. Include alert(0); to break the flow and find out what is happening. sometimes when i need multiple check points i do alert('the flow is now in function 1'); alert('the flow is now in function 2'); or sometimes just alert('success'); i would like to know if there is any standard way for debugging adopted as i am finding my current method very intrusive. thanks in advance..:)

  • New to javascript, why is jQuery such a beast?

    - by gnucom
    Hey Everyone, I'm new to javascript (functional programming is okay for me, though) and I am wondering how jQuery got away with some of the design decisions they made. Is it just too much work to fix now or what? For instance, there seems use of strange symbols in strings when accessing elements in the DOM or weird function definitions for $, that are forcing me to check references every other time I want to get some basic data. Can someone point me to a learning source where I can learn all of these nuances of jQuery (jQuery's examples just don't cut it, they're too spread out)? Maybe someone has a super good reference site/pdf for jQuery? Thanks

    - by meow
    Hello, this works great in FF but not in IE, Chrome or Safari. $('#countryDropDown option').click(function() { var countryID = $(this).val(); dostuff(); }); // countryDropDown = id of select So, as you can see I want to attach a click event to each option. I alos tried var allOpts = $('#countryDropDown option'), l = allOpts.length, i = 0; for (i = 0; i < l; i += 1) { $(allOpts[i]).click(function() { var countryID = $(this).val(); doStuff(); }); } It still does not want to work in any other browser but FF.

  • Stop setInterval within jQuery plugin

    - by Romelus
    I am trying to wrap up a plugin that I am writing but am stumped on a very trivial problem that I cant seem to find a solution for. I have tracked down almost every forum and related problem discussion. Any ways here is what I want to happen, my plugin has a timer that I would like the user to be able to handle its termination. (function ($) { ... var defaults = { callback : function(){}, crossfadeTime : 1000, easing : 'linear', running : 'true', // Here is where I would like the user to send a parameter // to invoke a different result. i.e. 'false' => clearing // the timer. Such as... var timer = setInterval(function(){ // Do Something; },3000); if(defaults.running == 'false'){ clearInterval(timer); }

  • Not able to send POST request through jQuery Ajax

    - by Amit
    Hi, I was trying to send an ajax request as POST request. But when i verified it on httpFox on firefox, the request is sent as GET. I tried pbht $.ajax() and $.post(). Many had a query regarding the same and had missed the "type" in $.ajax(), but even if i mention the type as "POST", the request will be of type GET. Here is my code: $('.test').click(function(){ alert("clicked"); $.ajax({ type: "POST", url: "www.testsite.com", data: "name=John&location=Boston", success: function(msg){ alert( "Data Saved: " + msg ); } }); }); Any idea why it happens?

  • How do I make the "back button" work with jQuery hide/show functions?

    - by Walker
    I'm looking for a way to append text to the url with jQuery so that the back button is not broken when a user loads new content with jQuery. For example, I have a three step form - the first step is (www.xyz.com/form-1). When the user clicks next step, jQuery slides in the next page. I would like that page to be (www.xyz.com/form-2). I know websites like hypem.com do this, I'm just looking for an elegant way to handle it.

  • jQuery expanding menu

    - by Milen
    Hi everybody, i have this html code: <ul id="nav"> <li>Heading 1 <ul> <li>Sub page A</li> <li>Sub page B</li> <li>Sub page C</li> </ul> </li> <li>Heading 2 <ul> <li>Sub page D</li> <li>Sub page E</li> <li>Sub page F</li> </ul> </li> </ul> With this JS code: $(function(){ $('#nav>li>ul').hide(); $('#nav>li').mouseover(function(){ if ($('#nav ul:animated').size() == 0) { $heading = $(this); $expandedSiblings = $heading.siblings().find('ul:visible'); if ($expandedSiblings.size() > 0) { $expandedSiblings.slideUp(500, function(){ $heading.find('ul').slideDown(500); }); } else { $heading.find('ul').slideDown(1000); } } }); }) For now the code works this way: When click on Heading 1, menu is expanded. When click on Heading 2, heading2 submenu menu is expanded and heading 1 submenu is closed. I need to rework it to this: Submenus must be closed automatically on mouseout. Can somebody help me? Thanks in advance!

Would love to be able to simplify this code, I have more code selecting the tag I am after then actually doing stuff with them.

  • SlideUp a div if any other div is slided down with jQuery

    - by John
    I have made a function to slidedown different div's by clicking different links. Following is basic code. However, there's a little problem that, for example, if i click on first link, it slides down div. Now If i click on next link, it keeps the first div, and slides down the second div. However I want to do it so that, if there is any div slided down, and I click on any link, it should slide up the previous div and slide down the newer one. I will appriciate your help in this regard. Thanks. $("a.about").click(function(){ $("#about").slideDown("slow"); }); $("a.info").click(function(){ $("#info").slideDown("slow"); }); $("a.contact").click(function(){ $("#contact").slideDown("slow"); });

  • jQuery image fade not working for unknown reason...?

    - by Henrik Petterson
    Just when I thought I was done for the night, another issue is keeping me awake. It appears that somehow I have broken the fade I was using on my thumbnails. If you go here: http://ftframes.com/milad2/ When you hover your mouse of the thumbnails, it should fade up. To give you an idea, this is a working version of the script: http://nothingcantouchme.com/stackoverflow.php#download_page As you can see, the hover works fine with the fade. And please mind the mess on this one, I just added it to demonstrate. Is there anyone that can kindly assist me in solving this issue? I would lie if I told you that I wasn't completely lost.

  • Javascript - Jquery .load() and setInterval() issue.

    - by Joe
    Let's say I do this: $("#content").load(...); Within what I'm loading some javascript is included: var myCounter = 0; var myInterval = setInterval(function(){ myCounter++; $("#counter-display").html("Count: "+myCounter); }); For an unknown reason, if I reload the content with $("#content").load(...); - myInterval is now being called twice. I tried doing something like: if (myInterval !== undefined){ //dont set interval again } However, it doesn't work. Does anyone know any method so that myInterval is cleared on .load, without needing to put the javascript outside of the loaded file?
