If I have the following in my document
<DIV id="leftdiv">
<DIV id="innerDiv1">
<DIV id="innerDiv1a">
<input id="input1">
</DIV>
</DIV>
</DIV>
How would I get a reference to the input1 element using "getElementById"?
I'm trying (document.getElementById("leftdiv")).document. ..
The following code displays the name for all three elements in IE, but fails

There has got to be a better way to traverse a doc than this code...
View 5 Replies View RelatedI am pretty new to jQuery, so apologies for such a basic question. But, it seems to me, the DOM is a hierarchical data set, and jQuery runs up and down this set in order render many of its results.I would like to understand, therefore, what method(s) jQuery uses to traverse the DOM. Is it using some form of indexing - a radix tree maybe?Developing the thought, I am wondering if there are any caching or optimisation steps I could take to help it along.I ask because a) I am always curious about these things b) I would like to write the best code I can based upon as much information as I can get and c) I am starting to use Ajax and, it seems to me, that the sequence and timing of asynchronous requests needs to be carefully thought through. If requests to the DOM can ever conflict (logically or otherwise) with requests to a server, I would like to understand how it all works.
View 3 Replies View RelatedI have an array called "Prods". Here are the different values in that array:
ProductName, HowManyCalories, ProductImage, LinkFromImage, Description, Price, BuyLink
There are a number of products. I'm just wondering how do I use "ProductName" as a product key to output its unique values?
Eg. the ProductName is "Chocolate Spread" - how do I output the "HowManyCalories" and "Product Image" only from the "Prods" array, based on the key "Chocolate Spread"?
Unfortunately, I couldn't find any way to traverse the object array in
reverse order. I'd thought there must be a way to do it with for..in
loop, but couldn't find anything yet.
i have something like that as menu:
<div id='main_div'>
<ul class='ul_main current'>
<li class='level1 item1'>item 1</li>
<li class='level1 item2 current'>item 2

<li class='level2 item1'>item 2.1</li>

I'm working on an image gallery at the moment and I'm having some trouble with the array the the images are stored in. The issue I'm having is that I can't figure out how to increase and decrease the current element in an array with the onclick event. Here's what I'm thinking so far:
var imageList = ['a','b','c','d','e'];
var position=0;
currentImage=imageList[position];
if a link with the id of "leftClick" is clicked, then position should decrease by 1 but if a link with the id of "rightClick" is clicked, then position should increase by 1 Both of these conditions should be bound to imageList.length i.e. if (position<0){position=0}; and if (position>imageList.length){position=imageList.length}; So how can I make "position" increase or decrease by clicking a link using the onclick event?
Can jquery be used to read/traverse a xml file?

I would expect it to show "2" but instead it shows "0". Why?
It seems the find() method doesn't work on the newly created elements. Do traversing methods only work on elements that are actually in the document? If so, how can I traverse and manipulate freshly created elements prior to inserting them into the dom?
I'm getting some XML back from an ajax call ... it's working as expected.My problem/question is that I don't know how to traverse the XML properly using Jquery.This is what I'm getting back:
<media>
<photos>
<photo id="1" size="s">url/photo1-s.jpg</photo>[code]....
My code currently uses $(this).find("photos").each(function() to get each of the photos, and that works fine.However, the list of photos can be quite large, and I really don't need them all -I'd like to just "grab" the one or two photos I know I need based on the id and size attributes. Is this possible without going thru the entire list?
I have an iFrame on a page where I am calling .mouseup(function()) on it's document child.Once in the mouseup function, I need to refer to a specific sibling of the iFrame.Unfortunately, I cannot figure out how to traverse backwards to the iFrame element from $(this) - where $(this) is the document. I get a null set returned when I try$(this).parents().
View 1 Replies View RelatedI want to restrict getElementById to search children of a specific element instead of searching the entire document, in the same way that I can do getElementsByTagName using a specific element as the parent.
In this particular instance the parent is a table and the elements I'm interested in are all TDs, so I did the basic getElementsByTagName('TD') off the table and looped through this array checking the IDs. However, I'm suspecting that the browser can do getElementById faster than I can do a loop in javascript. Is there a neater way to do this? For now, I'll settle for IE-only solutions, though it would be nice to have things work in generic browsers.
I am using javascript to switch between a series of divs, on clicking a navigation tab the divs display property is set to 'block' and all other divs have their display property set to 'none'. That works fine, the problem I have is when I redirect to another page (e.g. a PHP script) on return to the index the divs have reset and only the default div is shown, rather than the div that was showing when the user left the page. The solution, as I see it, is two stages: Write a function to display the relevant div based on the variable passed to it, then work out how to pass this variable around various pages (post/get). I am very inexperienced with javascript and it drives me mad that the script literally does nothing rather than throwing up an error (as in PHP) but this is what I have so far in terms of a function:

I have been trying to do some tooltips for a website and desperately wanted to learn something new and do that with jQuery.However, every time a mouse hovers over a tooltip, all hidden divs are shown, not just the one that supposed to. Here's my html:

<div class="tip">
<a href="#"></a>[code].....
I'm looking for some javascript to work with wordpress (jQuery preferrably) that will show/hide multiple divs on one click.
I had one working but it was kinda janky because it was causing me to have two divs with the same ID on one page. No good.
Since I updated to wp2.8.3 prior to launch, it's not working. So I've decided to just try and do it right.
Here's a page: [URL]
So, what I want to happen: On page load, the first tab: "general" and it's corresponding div beneath should be showing. And the first image should be showing. The other content divs and images should be hidden. I've given the text content divs a dashed border to show their borders. When a visitor clicks "dine at home" the general div and image hide, the second content div shows, as does the second image (it's currently the identical image, but the client may change later.) Etc.
I'll be using this function on a few other pages as well.
how to adjust this javascript to work on two different IDs at once?

I keep getting an error stating "getElementById("ballElement") is null, but I have a div with that exact id. I have looked at the JS script before that line, but found no errors there either. Please take a minute to see if you find something.

Should I use both name and id
<div name="abc" id="abc"> for using getElementById in NS?
I am trying to alter css using javascript as well as use the innerHTML
function. I have pasted below 3 forms that access getElementById in
slightly different ways (I wanted to rule out that it was the method.)
All 3 work fine on IE but only work momentarily on Firefox. For
example, one form has text that changes from red to black when the user
clicks the button. In IE it changes. In Firefox it changes for a
split second then goes back to black. Code:

View 1 Replies View RelatedI have this problem and when I came looking for help, I checked out the other thread like this but I couldn't get it to work. Here is the function -
PHP Code:
function newForm(focus, field)

{
if ( document.getElementById(field).innerText == '' )

}
if ( focus == 'yes' )

PHP Code:
<b>Field 1:</b> <input type='text' name='field1' class='textbox' value='____________' onFocus="newForm('yes', 'field1')" onFocusOut="newForm('no', 'field1')" /><br /><br />
<b>Field 2:</b> <input type='text' name='field2' class='textbox' value='____________' onFocus="document.form.field2.innerText=''" onFocusOut="document.form.field2.innerText='____________'" /><br /><br />
field1 uses the function but field2 uses just onFocus and onFocusOut but as you can see, it won't work.
Works fine in FF, Safari . . . but not with IE. The error is "Object doesn't support this property or method".I have narrowed it down to this line (and a few like it)name = escape(document.getElementById('name').value);The escape() is not the issue, same with or without.I am trying to capture the text value from the field with id='name'. I have found discussions about this problem with IE, but not a solution. This must be easy, just trying to get a cross browser solution to load a JS variable with an <input> value.
