Accessing Form Element With Non-conventional Naming

Jul 23, 2005

I'm building a website that needs to be able to check the value of an
element and give it a new value based on what it's current value is.

So for example, if I had a product and my code read like this...

<input type="text" name="name" size="20"><br>
<input type="text" name="description" size="20"><br>
<select size="1" name="public">
<option value="1">on</option>
<option value="0">off</option>
</select>

Assuming the name of my form was "form", I could access the value of the
text fields by "window.document.form.FIELDNAME.value" and the select by
"window.document.form.public.selectedIndex". But the page i'm working with
has multiple products listed and so I've addopted a nming convention for the
elements name's so that I could access it more efficiently in PHP. So for
example, I'd have multiple products as such Code:

Accessing Form Element Properties Using Onchange?

Jul 5, 2006

I have 1 form, and dozens of elements. In the select elements I use onchange="somefunc()". In this function I'd like to access and change the form element attributes (such as form.element.option[].value and form.element.option[].innerHTML).

Is there a way to access the element that has just changed (unsing onchange="somefunc()") by passing a "this.element" parameter to access the elements properties such as form.element.option[].value within the function?

JQuery :: Accessing Input Element By Its Value

Apr 2, 2010

In a project repeated blocks are identified by an <input type="hidden" value="x" /> field. To get an access to one of the block I wanted first access to that field. My first problem is there and I will explain it by a micro-project (tested with Firefox only)

Here is the HTML code :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]">
<html><head>
<meta http-equiv="Content-Type" content="text/html; charset=utf8" />
<meta http-equiv="Content-Style-Type" content="text/css" />
<meta http-equiv="Content-Script-Type" content="text/javascript" />
<link rel="stylesheet" href = "index.css" type="text/css" />
<script type="text/javascript" src='Library/jquery-1.4.js'></script>
<script type="text/javascript" src='index.js'></script> .....

And here the javascript code wher is the JQuery question
//meta http-equiv content-type charset=utf8
function test(){
var $id = $('#curUnion').val();
var $objet = $('#toutesUnions > .pseudoFieldset').find('input[value=$id]');
var $test = $objet.val();
var $objet2 = $('#toutesUnions > .pseudoFieldset').find('input[value="1"]'); .....

With $id = "1" as shown by the Javascript debugger (in Firefox) where is the difference between find('input[value=$id]') and find('input[value="1"]')
Giving the alert result => undefined / 1
If you want to test the micro project you will find it in the Test.zip joined. How to access the immediate parent pseudoFieldset to get its html code?

Accessing All Child Nodes Of An Element?

Feb 2, 2011

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

Accessing Element Properties After Setting InnerHTML?

Mar 21, 2010

I am dynamically building a part of my HTML page by setting the innerHTML of a DIV element. Immediately after I do that I try to retrieve the clientHeight and clientWidth of the DIV element in order to determine what height and width the element actually ended up being. But I always get 0 as both the height and width. The contents of the DIV, i.e. the HTML code that I inserted into it via the innerHTML, does indeed get displayed on the page. But I suspect that the browser doesn't actually update the page until AFTER my JavaScript code has completed and "returns control" to the browser.

Does that make sense? Is there any way I can force the browser to update the page BEFORE my code completes its processing, so that I can properly retrieve the width and height of the element I just inserted into the page?

JQuery :: Accessing A DOM Element In Dynamic Content Created Using AJAX

Oct 31, 2010

I am echoing some dynamic content into a DIV based on form entries. The content is essentially a dynamic table, with results populated based on the user input. The user can further refine the database results by entering more data into other fields. All of this works fine. What I'd like to add is the ability to click on an <a> tag header on each column to sort by that column. I haven't gotten it to work, so I wanted to try a more simple test. I currently echo <a id='test' href='#'>Click Me</a> into the DIV set aside for AJAX response. I then setup a jquery .click() event monitor to simply alert me when I click on it. If I place this <a> tag in the main portion of the content that is static, I get the alert box. But when I put this into the content of the DIV tag generated dynamically by AJAX, it doesn't fire the alert. Is there something I need to do to 'reload' the page? Is the dynamically added content not part of the document since the entire page isn't reloaded?

JQuery :: Accessing Value In Ajax Form Without Submitting The Form?

Jun 2, 2009

I have a form. Upon submit, the data is sent to the server. Under certain conditions, the form is replaced via ajax with a set of radio buttons that offer the user a a choice.I need to access the radio buttons before I submit the form again.Normally I could just access the buttons with getelementbyid but it is not available, presumably because they were generated via ajax.I could submit the form just to access the radio buttons and then submit it again, but I'd like to avoid that.

Count Checker - Track Of How Many Chars Are In A Field On An Asp Form

May 19, 2010

I have a js counter which keeps track of how many chars are in a field on an asp form. When the user clicks a button further down in the form, the form generates more fields. This also causes the js counter to reset to its original value, as the page is 'reloading' in a way. How can I check this value and keep it the same when the user clicks this button?

I am including the code I have.

javascript

counter in code

button

I have tried

It compiles but the value remains reset.

Accessing A Variable Through A Form Name

Jul 23, 2005

I have 2 arrays:

var A1 = new Array();
A1[ 0 ] ="Y2";

var B1 = new Array();
B1[ 0 ] ="Y1";
B1[ 1 ] ="sink";

I also have a drop down menu with the names of the arrays. Say:

document.form.option[1].text returns 'B1'

Can I transform the string 'B1' into the array B1, so that:

document.form.option[1].text[1] returns 'sink'

Currently I'm doing this with conditionals, e.g.

if(document.form.option[1].text =="B1){do stuff}

but this gets a bit messy.

Accessing Form Id Values Using DOM

Mar 27, 2011

I am undertaking an assignment where I have to create a webpage that reads values from a database, and generate the appropriate amount of sliders (scroll bars) according to the number of database entires. The webpage functions like this: On index.php load, it reads all the slider values from the database and automatically generates and sets each slider to that value On setting each individual slider to a new value by adjusting the slider, the code automatically updates the slider value in the database via AJAX.

So far I have gotten both functionalities to work successfully. There is just one problem with the 2nd functionality. I can only get one slider value to save to the database at a time. I know how to fix the problem, I just do not know to achieve it. I shall now illustrate via snippets of code:

Accessing Hidden Objects In A Form

Jul 23, 2005

Can anyone tell me the best way to access a hidden object in a form? I could use a hard-coded index to the elements of the form, but it's too easy to add something before the hidden object and mess up the indexing. For example:

The form has a tagid of "myForm"
The hidden object has a tagId of "myHiddenObj"

I can get the form elements by using
var formElements = document.getElementById('myForm').elements

But there doesn't seem to be any way to do this:
document.getElementById('myHiddenObj')

Assuming I have the elements as obtained above, none of these have
worked for me either:

formElements['myHiddenObj']
formElements["myHiddenObj"]
formElements.myHiddenObj

Anyone have an idea?

Accessing Form Data From Javascript

Jul 23, 2005

I've been using some code to verify form data quite happily, but i've
recently changed the way my form is structured, and I can't get it to work
now.

Originally :

The form is called "form1", and I have selects called "PORTA", "PORTB" ...
etc...

I then had javascript that accessed these selects as below, and it worked
fine.

ind = document.form1.PORTD.selectedIndex;
val = document.form1.PORTD.options[ind].value;
dev = document.form1.PORTD.options[ind].text;


My form is now autogenerated, and form data is stored to file, so I now use
an associative array for thte form elements (so that I can loop through them
easily), The form elements names are now :

McuCfg[PORTA], McuCfg{PORTB} and so on

Now, I modified the javascript so that it now uses the McuCfg[] associative
array :

ind = document.form1.McuCfg[PORTD].selectedIndex;
val = document.form1.McuCfg[PORTD].options[ind].value;
dev = document.form1.McuCfg[PORTD].options[ind].text;

When the script runs, I get the error

"document.form1.McuCfg.PORTD is null or not an object"

I have used the same notation that i know works for the "options" array
although that's not an associative array.
