I know this isn't a jQuery question per se, but maybe there is an easier way to do this is jQuery than in javascript?
<script>
I was wondering if there is a better way to accomplish the above? Rather than directly changing the innerHTML of the element is it possible to add a onclick listener (or another javascript listener) to the element in a more direct way without having to go through the html.
I have taken over from a developer who has used javascript to add additional text input boxes to a form so there is no limit to the number of input boxes there can be. I have got a jquery autocomplete function that works fine if the input box is added by the server but the listener doesnt fire when the text box is added client side. As with all things this is part of a much bigger project and I only want to change the smallest possible part (add autocomplete to this text input box) MY QUESTION: is it even possible fo ra jquery listener to fire when the input box has been written client side after the page has loaded? Is there a way to "refresh" a listenerto find the new tag that have been added?
View 2 Replies View Related.change() is only for form elements minus check boxes/radio buttons, etc.Are any of you aware of a script that does this already? Hopefully one that is easy to implement.I just want to monitor things like height, number of inner elements, or any change in the inner HTML.
View 1 Replies View RelatedI want to change the content of different div's using .html(). The change should be done by clicking on the inner element of the container.

I have a quandary of sorts here dealing with a list of checkboxes and the hiding/showing of a few divs associated with the checkbox selection. Here's basically what I need to do: Hide the lower div if no checkbox is selected. If any one of the first 6 checkboxes are selected, and NOT any of the remaining 6, then show the div. If at any time during selection one of the remaining 6 checkboxes are selected, then hide the associated div. Note this code doesn't really do much. I'm still trying to architect a solution that's best.
var aThroughf = false;
var gThroughl = false;
$('[name="'+q2030.name+'"]')).live('click', function() {

I'm trying to come up with a better architecture for dealing with multiple listeners in a multi-page questionnaire. Here's the general structure I'm looking to implement:
1. Set up CSS for animation
2. Look for preconditions
3. Initialize listener
4. Execute animation
Some issues to consider:
1. Some questions have dependencies that show or hide depending on what is selected in a parent question.
2. Needs to be IE 6 compatible.
3. It should be simple enough so that all you need to do is add a new question to a JSON object, which is what I have set up right now.
Some code (the looping structure that reads each question):
var newQ = eval(q);
$.each(newQ, function () {
// 1 - Setting CSS for each listener
$(this.css).css({'width': '1500px', 'float': 'left', 'clear':'both'});
[Code].....
The problem here is that when I do a console.dir on $.each(this.value.length), it counts each character, as opposed to counting the number of elements in the array. Should I be doing an eval on q? Why or why not? If I could get this up and running, it would make my life 100x easier, as there are hundreds of questions, and I'd want to make this all data driven.
I feel like I must be missing something simple but I can't put my finger on it...
I'm moderately new to JS (programmed in other languages though) and am working on a Google Maps project.
This piece of code should show an alert of the region's name when a map polygon is clicked. Instead, no matter what polygon is clicked, it only does the name for the LAST iterated placemark. code...
What am I missing? What would be a better way of handling this?
Does anyone know where I can find a complete list of DOM/DHTML event types documented?
I'm trying to learn more about advanced event handling in JavaScript and I'd like to find lists of event types that I can attach/add event listeners to. I've been searching around and I've found a few resources, but nothing that seems complete.code...
Here's the situation: I have a javascript object for controlling a custom DHTML scrollbar. So that I can use more than one on a page, the event listeners need to be passed a reference to the particular instance of the object that each needs to connect to, but as I discovered the hard way, inside an event listener, 'this' returns a reference to the DOM object throwing the event, rather than to the JS object. Short of coming up with a linked list of different objects and having the event handler search through it for the right object when an event is generated, then writing a reference to that object to some global variable, is there any convenient way to tie this together? I hope I've made myself clear enough...

(I am currently only checking for non-ie browsers) code...
So I know all about the caviats of the 'this' keyword when calling object functions from event listeners:
Code:
var foo = {bar: true, zoo: function() { return this.bar; }};
foo.zoo();
> true
a = foo.zoo;
a();
>
And I know that I can get around this by using an anonymous function so that 'this' is preserved in it's original context:
[Code]...
But then someone pointed out this article on memory leaks when using anonymous functions to call object methods because the anonymous function gets access to ALL variables in the enclosing environment and my not be properly disposed of by the garbage collector [URL] So that lead me to think about using a "3rd-person" approach to referencing object properties from within object methods.

I have PHP file called file1.php with an empty <div></div> in the middle. I've added a 'load' event listener so that on page load, it calls an AJAX function that calls file2.php. file2.php creates a table and loads it into the <div></div> in file1.php.
file2.php has <a> tags in it's <th> columns and I wish to trap when a user clicks on the column heading. The old way was to use the onclick() method but I'd rather use event listeners.
Here's my problem. I am getting "obj has no properties" when trying to add those listeners. I *think* it is because the code in file2.php isn't part of the original DOM tree for file1.php. So how can I use event listeners instead of onlclick()? I know I can add top the DOM by creating elements and appending them but that adds to the HTML code and my code is already in place via the AJAX call. What to do...? DO I just use the old passe onclick() method?
I'm trying to add event listeners to multiple elements of the same class. The DOM is something like this [code]...

I am creating JS objects that have some properties that contain DOM nodes, and some of these DOM nodes have event listeners attached to them. When I delete such objects, do I first need to remove the event listeners attached to some of the DOM nodes? And do I need to use removeChild on the DOM nodes that are properties of the object? Or does JavaScript take care of all that?
View 1 Replies View Relatedhow to modify the DOM with jQuery in order to correct an (dynamic) HTML structure. I have a markup like this:
Thinking about a replacewith or append or a combination??
<ul class="MyClass">
Test1 <br />Test2</ul>
But I need to get all texts in the UL be surronded by LIs, and to delete the br.
<ul class="MyClass">
<li>Test1<li>
<li>Test2</li></ul>
In real life this could be a like two text elements like in this example, but it´s dynamic so it could be like 3 or 15 or whatever sometimes.
I used the jquery-function replaceWith() to replace this html part <div class="montag">...</div> with this part <div id="ersatz">...</div> Then i implemented a listener for montag and a listener for ersatz, so I can switch back and forth between the different parts.
The side gets loaded within the montag div and when i click on this part the listener works and the html gets switched to the ersatz part, but after this the listener for ersatz does not work, although the modified html gets displayed in firebug. Are there any solutions for such a kind of problem?

I'm a web design student who has designed a website for a family member in my spare time. The website uses 5 html documents and all share one css document, it has no jscript docs. Recently, we learned how to use jscript to set up an image gallery in class where clicking on a certain button changes the picture shown on the page, my question is can the same thing be applied to the contents of an html document?(<p>,<a>,<img>) I'm aware you can change the contents of say, a <p> with an id tag but I mean to do it for a whole sections of the site. That includes paragraphs, images etc.
If so, it would be great to cut down my html from 6 pages to just one.
