Trap A Click At The Div Level?
Jan 3, 2010
At certain times I need to prevent the user from clicking on elements in a div. I've tried giving the div an onclick that simply returns false, but the clicks still get through. In the simplified code below, the onclick is hardwired, but in real life it would be assigned dynamically. In this example, when I click the link to Google, I get the "yo" alert, but the Google page still loads. If it were just one link, I could disable it directly. But I'll be dealing with pages with lots of links on them. How do I do this??

I am trying to trap the shift+click event of a DIV. Works in IE and Chrome but not in Firefox. Purpose of the code: The DIV provides a hidden link (no decoration) for an editor who wants to edit content. The DIV ignores a simple click (meaning a click without a combination of the shift key) to avoid accidental access to the casual surfer. Here is the logic of the code: DIV is clicked. call function to check for the shift key being depressed if the shift key were depressed during the "click", initiate access. If the shift key were not depressed, ignore the "click" Here is the HTML code:

I am trying to turn a single level flyout menu into a multi level one.
It uses a dt for the title, and a ul within the dd for the menu items. The dd opens to the right of the dt.
The problem is that the second level menu (a dl within an li within another dl) [URL] - flyout4 & subflyout5.
The z-index is increased each time. I just can't figure why the area is limited.
javascript, css & html follow -
Code JavaScript:
/** FLYOUT = vertical dropdown **/
var Flyout = {
DDSPEED:10,

I would like to trap the MouseOut event of a DIV.
The problem is that the DIV contains an UL.
When the mouse enters the UL, it triggers the MouseOut for the DIV container. I only want to trigger an action when the mouse leaves the outer edge of the DIV.

I am trying to use the following code to trap JavaScript errors. It seems to work well in IE and FF but not in Opera. I expect I must have turned it off somewhere in the "preferences" but I can't find where. I'm using Opera 10.10.
Code:
<script type="text/javascript">
function Err() {[code].....

I have been searching for a way to trap changes done to the document object (mainly by the function document.write();).
Example of code that doesn't work:
function myFunction() {
ed.document.onchange = doFunction(document.body.innerHTML);
ed.document.open();
ed.document.write('Hello');
ed.document.close();
}
function do_function(body) {
alert(body);
}
It only fires when the page loads, not when I change the text. You are free to use any event that works, but i think onchange was the one to fit this problem. The alert will write the initialpage, but will never write the tekst 'Hello' that is the new change.
Any javagurus out there know a solution to pick up any fired events triggered by document.write();

Im having trouble trying to access some values of the response from an API service. My code to connect and output for each item is working Ok getting the name and age. But I can't work out how to get the image urls.Clutching at straws I thought I could just target the first value stored using $imageURL = item.images['url'][0] but that fails.
Code:
$.getJSON("http://api-address", function(data) {
var html = '';

3-level dropdown box: [URL]. Now in this dropdown menu if you select:
Category > Cars
Sub category Cars for Sale
Sub Sub Category Ibiza
What I want to do is two things:
1)Place a value on all the Sub Sub Category(ies) so for example the value of Ibiza I want to = 55
2)Then Grab that value? How would I get that value and grab it from POST?

I would like to use the menu that is linked below. I implemented it on my website but I discovered that it can only go 2 levels deep. I would like it to go one more level and I think that would be done in the javascript but I can't tell for sure. Could someone steer me in the right direction? [URL]

I've got a document that I want to ensure always get loaded into the
top level document and not into a frame or iframe. I've got it figured
out how to detect if the document is loaded into a frame. But what I
want to happen is the HTML content in the iframe to be displayed in the
top level document w/o a return trip to the server.
Here's what I'm thinking:
function forceTopLevelDocument() {
if (top != self) {
//load the HTML from child document into parent document
//without a return trip back to the server
}
}
What I can't figure out is how to take the document loaded into a child
frame and push it's contents up into a parent frame.

Given the following markup
<div id="menu">
<ul>
<li><a id="home" href="#">Home</a></li>
<li>
<a id="about" href="#">About</a>
<div>
About sub menu
</div></li><li>
<a id="products" href="#">Products</a>
<div><h2>Books</h2>
<ul><li>ColdFusion</li>
<li>jQuery</li>
<li>CSS</li>
<li>HTML</li>
<li>Groovy</li>
<li>Hibernate</li> .....
How can I grab only the 1st level children of my node? I want direct decendents of menu only. My code below is grabbing all <li> which is going to be a problem.
(function($){
$.fn.extend({
myplugin: function(options){
return this.each(function(){
// the object we are working with
var obj = $(this);
// get a list of menu items
var menuItems = $('li',obj);
});
}});
})(jQuery);

I'm trying to make 3 drop downs (based off of mysql tables), to narrow down the selection. Source, School, and Program. So when when they select SOURCE(source), all the SCHOOLs in drop2 will be based on the SOURCE selected in the previous dropdown, and whatever school(cid) is selected, the program will be based off that school(cid) and display all the programs for that school. I've google'd high and low for something, and no avail. Here is what I have, I am just trying to make 3 drop downs narrow in, without pressing submit (I am new to ajax and javascript etc) The issue may be in that java part, I've look in the php and mysql, but nothing.
PHP Code:
<table width="517" border="1"> <tr>
<td width="87">Source:</td> <td width="414">
<? echo'<select name="source" onChange="showUser(this.value)">
<option value="">--Select--</option><?php while() { } ?>'; .....
My javascript
Code:
var xmlhttp;
function showUser(str){
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null){
alert ("Browser does not support HTTP Request");
return;
} .....
Right now, the results display in a table, I don't want that - I need them to display as results in the next dropdown.
