I'm not a JS expert or anything, but I was just wondering if it is possible to get the value of an element from its ID. For example, if I have something like (inside a HTML document):
<span id="12345">0</span>
Is it possible to retrieve 0 if I specify that I want to retrieve the value from the ID 12345?
i want to retrieve the value of different elements in the page . Like listbox , testbox and some other.

I was able to produce the below XML:

I have the following html:
<div id = "container"></div>
<div id = 'containerItemTmplt' class = "ui-widget-content">
<div class='contentHdr' onclick="test(this)" />
</div>
i then use jquery to clone 'containerItemTmplt' and add it to 'container':
var copiedElem = $('#containerItemTmplt').clone(true).
.attr('id', 'paneI1')
.appendTo('#container');
This works great and i confirm using I.E. 9's developer's tool utility that the element was indeed added with the correct id as a child of 'container'.
However in my test method, when i inspect the element that was copied, the id attribute is an empty string:
function test(elem)
{
var parentItem= $(elem).closest('div')[0];
alert(parentItem.id); //<--this displays an empty string despite
}

View 15 Replies View RelatedWe are trying to develop an Engineering application using PHP,
Javascript with Informix as the back-end.
Is it possible to retrieve data using Javascript but by accessing the
Database. Say somebody enters part_no, than using Javascript is it
possible to connect to the part master and retrieve the division and
desc information?
I am not allowed to use the PHP because this will require the user to
insert the part number on the first page (user input page) and then
retrieve the information using PHP and display the info on the second
page (processing page).
I will need this to be done on the same page. That means the info will
need to be retrieved instantly (on the fly).
I think of building a javascript array for the part master table using
PHP but finally decided not to as the table is a huge table (contains
more than 1000000 records).

I want to retrieve any web page content using javascript . suppose
I logged into my gmail account and opened my e-mail. now i want that a
javascript will execute on the page and read all text content from
that page (e.g. all email subjects ) and save it in a text file . I
may embed the script in my browser. Is this possible ?
Here's the situation. I have a static html page which we want to update
to include some dynamic content. I want a counter that keeps track of
the number of times anyone presses the "add" button, and display that
number. So, that page would look something like:
Number of calls today: 5
Add | Reset
The "5" would increment with every click of the "Add" link. The "Reset"
link would reset the counter to 0.
I have a Perl script that does all of the accounting stuff (opens a file
that contains the number, increments it, resets it, etc). What I don't
know how to do is to get the data from the CGI script to the web page.
I'm imagining that you can use Javascript, but I can't figure it out.
My CGI script can accept three options (add, view, reset). So it you
call it like so [myscript.cgi?action=add], it increments the counter by one.
So, in a nutshell, this is what I want:
1) the web page to display the # of calls upon load.
2) When a user presses the "Add" link, it invokes the CGI script to
handle the accounting stuff, then refresh the page with the new number
of calls.
3) When a user presses the "Reset" link, it resets the counter to 0.
This is in connection to the tread: Re: changing browser text settings?
I am wondering if there is a way to retrieve the browsers text size (not
change! ;-) ) so that I can dynamically resize the size and position of the
layers to accomodate larger than normal text-size settings. I really hope
there is because it would mean not re-writing the whole page (which I'm not
sure how to go about).
the page is here:

I wrote this simple snippet to animate a listitem from an unordered list. Here it is:
function OnLoad() {
$('#navigation').mouseover(function() {
$(this).find('li').stop(true, true).effect("pulsate", { times:2 }, 150);
});
So I have a div with id "navigation" which contains an <ul>, and the <ul> has several <li> items.What I want to do is to animate the <li> items as i rollover them.My question is , how can I only animate the current <li> I rollover, because right now when I rollover one, all <li> items animate.

I'm trying to use AJAX to load user's profile through a drop-down list on selected user. There are 3 seperate files:
1) view_info.php
2) selectuser.js
3) getuser.php
I tested and found that the value $q did pass from view_info -> selectuser.js -> getuser.php, and value changes correctly as i select different user from the drop-down list. Problem is, it simply can't fetch data from my database using the value $q. I tried debugging it for 3 hours already and is totally out of idea whats wrong with the script. i'm new to AJAX, this is my first script..
