I have a function which looks like
function mainLeftElements(){
var containerDiv = document.getElementById('mainLeft');
var elems = containerDiv.childNodes;
alert(elems.length);
}
Which for a div declared like so:
<div id = 'mainLeft'></div>
Alerts me it has a length of 1, trying to work out what the element is (thinking it might be a blank text element or something, maybe the id attribute also??) by using
elems[0].tagName
and
elems[0].id
I get confused as they both return 'undefined', so what is it?

i have a menu generated by a list with nested lists. i want the parent link to stay highlighted when the mouse hovers over the sub menus. because those sub menus are also generated by jquery (qtip), CSS alone won't do it (triedul.topnav li:hover a {background-color: #F00;}).is there a way to do this using jquery?

I have a javascript here for adding my div element to my registration form,Adding the div element is easy, but it shows on the bottom of my form. I cant make it as the first child element of my form...This is my code
var _form = document.getElementById('registration_form'); var errorDiv = document.createElement('div'); errorDiv.setAttribute('class', 'confBox');
I am using the JS and HTML code below to check that required fields are completed for attributes of a product. The first attribute is a select menu and the second is a radio set. My JS goes through fine and detects if the select menu isn't selected with a value, but I keep getting 'undefined' for the radio element type. I've almost pulled out half a head of hair wondering why. Any experienced eyes see something I don't? Code:
How do I get the contents of an element in the opener and show them in the child?
What I'm trying to do is something like this:
In the opener: <h1 id="pgtitle">Office XP</h1>
In the child: function gt_pageCont () { var pagetitle = window.opener.document.getElementById("pgtitle"); var pagetext = "<h1>""+title+""</h1><p>Here are some more info about "" +title+ "".</p>"; document.write(pagetext); }
and: <body onload="gt_pageCont();">
I know that something is missing in the function, because I've tested it and the child displays [Object] instead of "Office XP".
I've got a reference to a TableCell and I'd like to use jQuery to get the first instance of an <IMG> tag within that TableCell, but can't get the syntax right, I understand how it would work if I were to reference the TableCell by and ID or class, but not when I have a direct reference to the cell, I've got:
What the jQuery syntax should be to get the first img tag within "tdRef"?
I need a way to select BOTH the first occurrence of <div class='posts'></div> and the LAST occurrence of <div class='posts'></div>. Then I need to set different css rules for both of them. In CSS, I can use first-child, but this doesn't work in older browsers. CSS last-child does not work here because it targets date_area and also doesn't work in older browsers.
I'm using the following code that adds to <a> tags to each <td> inside a table. $(document).ready(function() { $('.calendar td:not(.notinmonth.)').each(function() { $(this).append('<a href="#" class="available am">AM: Available</a>').append('<a href="#" class="available pm">PM: Available</a>'); }); $('.calendar td:not(.notinmonth.)').each(function() { $(this).has('.event').remove('.am'); }); });
The second half of the code looks to see if any of the cells contain an element with class 'event'. If one exists, then the '.am' anchor should be removed. However this does not appear to be happening. After carrying out a few tests with the 'alert' function, it looks as though the script thinks that every cell contains a '.event' element, but I have no idea why! Not only that, it doesn't remove the '.am' link from any of them.
Here is the markup for the table (the cell with 'Day 9' in it is the only one that should match having an '.event' element: <table class="calendar"><thead> <tr><th>Mon</th><th>Tue</th><th>Wed</th><th>Thu</th><th>Fri</th> <th class="weekend">Sat</th><th class="weekend">Sun</th></tr> </thead><tbody> <tr><td class="notinmonth"></td><td class="notinmonth"> .....
My HTML is like this: <div class="feature"> <h2>Heading Goes Here</h2> <img src="photo.jpg" />
[Code]....
What I want to happen is for the element inside the .feature class to appear when the <h2> of that <div> is clicked I tried using next() and a few other methods but it doesn't work as neatly as I want it to - how can I tell jQuery to just return the element within that div (and not all elements which are inside a .feature class)?
I've 2 field sets and a div inside each fieldset with some contents. When the legend of the current fieldset is clicked, I will toggle the div contents. I'm trying to write a generic function which can be used by everyone. Here is my design:
I have the usual unordered list for a navigation menu with submenus...
html:
<ul> <li><a href="#">Link 1</a></li> <li>
[code].....
All of the links inside of the parent <li> have a border radius. But if the parent <li> has a child <ul>, I don't want the link to have a radius.I'm currently using this jQuery:
here it now selects all a tag in "lists" but I only want it to reference the a tag that is the direct child of "lists" li. I want it to ignore the freen highlighted part.
I have been scratching my head on this one for a couple days:
Code: function hideAll(){ var education = document.getElementById("education").childNodes;
[Code]....
As far as I know, this should be working the way I expect it to (set the display of all the childnodes to none), but I guess I'm missing something. Is it not possible to instantiate a variable using childNodes without choosing a specific index of the array? I just assumed it would work like any other array
please see the code below.at the moment, when you click img, click eventtriggeredbecause parent element has click event.I want click event not to be triggered when you click img.How would I do that?
Basically, I'm looking for a way to find a list element that has a ul child, and then hide or show that ul. What I have here doesn't seem to be working.
How can I pick an id element (here #bridge1,#bridge2) and toggle its child (here a p element) without actually using the id element as parent? 'this > p' apparently does not work. $('#bridge1,#bridge2').click(function(){ $('this > p').toggle(); return false; });
I was wondering if there is a "selector construct" that matches an element having more than one child. So I'm looking for a solution that doesn't need an if statement such as;
if($('ul').children().size()>1) { //do this }
[Code]....
But I'm looking for a selector that already looks for these conditions. Kind of like how :has() works but then a check for more than one child.
I have a small problem with a page I'm working on. I have an anchor tag inside a table that has a mouseover event that updates a contextual help box. I need to add a similar mouseover event to the anchor tag that does the same thing, but updates the help box with different text. The problem I have is that when the mouse is over the table, no matter if I move the mouse over the anchor, the help text only displays the message that is passed from the table's mouseover function call. I think the solution *may* be something to do with event bubbling, but I'm not exactly sure how to implement it. The code I'm dealing with is below:
I'm customizing the cycle plugin a bit from [URL] , which slides through a number of items.The issue I have is selecting a child object, to get its 'alt' attribute, and display it as a description. Using the default example:
function onBefore() { $('#output').html("Scrolling image:<br>" + this.alt ); }
...works great when each item is an image. But I need to link each element, so my markup looks like this:
i am curious if there is a simple solution to this very common problemim sure lots get.i have a div with some children items in it and when i fade one ofthem out the div jumps down to the appropriate height. i would like toknow is there a simple way to animate the div to shrink nicely insteadof just jumping to its new size?
