Label Properties For Form Elements
Feb 14, 2003This is pretty simple, but if you've ever wished that the DOM exposed a label property for any form element that had a label specified for it, well, you'll enjoy this.
{
var labels = f.getElementsByTagName( "label" );
for ( var i = 0; ( label = labels[i] ); i++ )
f.elements[label.htmlFor].label = label;
}
Just pass it a reference your form and voila! You now have element.label.
Object Properties With Array Syntax - Add Extra Properties To Html Elements
Nov 13, 2009how to add extra properties to html elements as I was storing data in html attributes. After looking at some others code including Raphael and this addEvent code. [URL] They seem to treat objects just like an array. obj[property] = value; This would have been extremely helpful to know previously as I have needed to be able to include variables in property names - but have resorted to making the whole thing a string and calling exec() on it.

Modifying Form Data Before Submission
Jul 20, 2005I have a form which houses basic inputs, as well as a few multiple select forms.
I need to parse all the 'values' which are in this multiple select form (it
gets manipulated dynamically client side). I wanted to create a function
that loops through all the form elements, and if the type 'select-multiple'
is detected, gather the VALUES of each <option> inside it.
The bit I'm stuck on is then how to reconstruct this into a form submission.
Preferably I wanted the data from the 'select-multiple' element to be
submitted as comma delimited, eg 14,12,512,63,62 which would later be parsed
by PHP.
I was considering reconstructing a query string and submitting that as GET,
but I'd prefer to POST it along with the other data (such as INPUTS etc)
which do not need to be changed.
Can I somehow attach some 'hidden' type data onto the end of the form
submission at this point?
Accessing Form Element Properties Using Onchange?
Jul 5, 2006I 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?
Where To Find A List Of Properties (Particularly For Form Textboxes)
Jul 1, 2003Anyone have an online list of properties that can be changed?
In particular, I'm looking to change the properties of a textbox in a form. E.g. Border colour & background colour.
This bit of code allows me to change the text that is initially in the text box (before a user starts to type).
Code:
document.myForm.tboxMsg.value="New Value";
<form name="myForm">
<input type="text" name="tboxMsg" value="Old Value">
</form>
The question is - what else can I change & is there a big list somewhere?
My use of the word "properties" and maybe others may be incorrect...Apologies in advance, I really don't know much about javascript.
Jquery :: Realtime Order Form - Change Form Elements Depending On Selection
Aug 25, 2010I've been struggling trying to get a small order form to work the way I want it to. Here is a link to the live page: [URL] And here is the code in question:
[Code]...
I have two questions...
Question 1 How can I make this piece of script act a little smarter. Look at the order form, I'm catering for up to 4 people and providing lunch for them. If they select 3 people and the spaghetti bol for lunch, it's only adding $10 where it should be adding $30. Obviously this is simple multiplication but since the values in my form are prices it makes it a little tricky. I'm guessing an onselect on the first part of the form which changes the pricing of the other items would be the way to go, but how do I do this?
Question 2 The "Total Price" is placed before the <form> tag by the script. This is ok but it's not where I want it. How can I position this text elsewhere in the document?
Pass User Input From A Form To One Database Field Using Several Form Elements
May 4, 2009I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.

This.parentNode - Access The Elements Of The Form Without Referring To Them By ID As The Whole Form Is Intended To Be Cloned
Feb 16, 2011I've put together what I think is an illustration of my problem at [URL] Quite simply, I need to be able to access the elements of the form without referring to them by ID as the whole form is intended to be cloned. I intended to do this using parentNode and childNodes[] together with the 'this' keyword. My understanding of 'this' in this context is that it should refer to the HTML element calling the function, i.e. one of the radio button inputs. However this gives the error "Error: this.parentNode is undefined"

JQuery :: Get Form Elements Added Dynamically To Be Included In The Form?
Oct 13, 2010I have a grid that I'm adding rows to that include form text input boxes using addRowData. I know I can use the "editable:true" for that but I'd rather not at this time. Anyway I have the <div id=list1></div> surrounded by a <form></form>. Also statically I have a couple of text input boxes and a submit button. When I press the submit button the only parameters that show up in the POSTED data are the static ones. Is there a way to get the form elements "registered" with the form? I know I can always use javascript to extract the data and save it via an ajax call, but if there is a way to do it "correctly"
Example
var myRow = {id:"0",call:"<input name='callt"+boxNo+"' id='call"+boxNo+"' class='calls' type='text'/>",amount:"<input name='amt"+boxNo+"' id='amt"+boxNo+"' type='text' value='"+defaultDep+"'/>",residual:"",calculate:"<input type='button' class='buttons' id='b"+boxNo+"'/>"};

Modifying ChildNodes Of A Cloned Div
Nov 23, 2005I have a div 'readroot' that I clone. I change the change the id and
name of the childnodes of 'readroot' to the original name plus a
number(counter).
The problem is I have i have a div 'serials' inside 'readroot' and the
childnodes of 'readroot' are not modified with the current function i have.
What is the best way to modify the childnodes of the div serials?
I guess i could put another for loop inside the for loop of the
moreFields function but i am thinking a recursive function could do it. Code:
Modifying Pull-down Menus
Mar 17, 2007I have a page with 2 drop-down menus. The task is, when you select
1 menu, your selection then changes the options available in the
other. This data happens to be drawn from a mysql database, so I
wouldn't think that it could be done purely in Javascript, but rather
a combination of PHP generating some JS code. Thing is, I don't even
see how to change a menu's available options with JavaScript, only
names and values of individual fields.
Modifying HTML Table Through DOM
Jul 20, 2005The basic concept is a music playlist that I'm trying to write as a
table inside a div.
I have Song and Playlist 'classes'. The Song class has a Write()
method, as does the Playlist.
The Song.Write() boils down to this:
var tr = document.createElement("TR");
var td = document.createElement("TD");
tr.id = this.ID;
tr.appendChild(td);
td.innerText = this.Artist + ' - ' + this.Title;
td.onclick = function() {top.playSong(this.parentElement.id);}
return tr;
The Playlist.Write() call is essentially this:
// this.songs is an Array of Song objects
for (var x = 0; x < this.songs.length; x++) {
playlistTable.appendChild(this.songs[x].Write());
}
When I attempt to call playlistTable.appendChild() after creating the
table via document.createElement("Table"), everything works fine,
except I have no way to add the table to my document, since the div I
want it in won't believe that appendChild() is a valid method. If I
put the table in the div as a <TABLE>, and then try to append to that,
the *table* doesn't accept appendChild() as valid. Specifically, I get
an 'Invalid argument' error when calling either.
Modifying An Autocomplete Script?
May 1, 2009I have been working on an autocomplete script that I have modified to be used with JSP's/Servlets. The script is working very nicely, except for one minor issue. When the user selects from the suggestions in the drop down list, for some unexplained reason, an extra space is added to the word in the text field. Also, I would like to modify this script further, such that if a user enters more than one word in the text field, the autocomplete script is activated for each word, instead of ONLY the first word.
I have added the entire code for the JavaScript file that is responsible for the autocomplete feature below.
The link from where you can download the autocomplete files is here:

a demo of the script can be found here:

FYI, I am using the version that uses XML.
Below is the JavaScript code for the autocomplete file I am using:
if(typeof(bsn)=="undefined")_b=bsn={};if(typeof(_b.Autosuggest)=="undefined")_b.Autosuggest={};else alert("Autosuggest is already set!");_b.AutoSuggest=function(b,c){if(!document.getElementById)return 0;this.fld=_b.DOM.gE(b);if(!this.fld)return

Modifying Content Before It Is Rendered
Sep 20, 2006How can I modify a page before it is rendered? I tried using greasemonkey to remove a script, but it runs it anyway. Is there some way I can get rid of a script on a page before it runs.

Modifying The Look / Function Of An Alert Box
Nov 8, 2010<script type="text/javascript">
function confirmation()

alert(
"Please Confirm Before Proceeding !" +
"
" +
"Display Name: " + document.forms["paypal"]["os0"].value +
[Code]....
First though JS is not my strong suit and the above code is something I found at the W3School site or whatever it is. What I would like to do if possible is add a Cancel button to the alert box that when clicked cancels the form submission it's attached to and keeps the user on the current page to modify the data they entered in to the form should they want to change it. As it stands, all there is is an Ok button and if you click the red x in the corner it acts as if you clicked ok so if a user wanted to change their form data they'd have to close the browser to start again. Aside from liking to add a cancel button I would also like to if possible change the alerts Ok button to read something different. Not sure yet, thinking either Submit or Proceed.
Modifying And Writing Contents Of A TextRange
Jul 23, 2005I’m trying to modify a DHTML editor that parses a style-sheet
via PHP and instead of modifying the tags via execCommand(), find a
way of writing inline styles by way of adding <span style=> tags
around the selected text.
Easier said than done. My first though was to do a search and replace
on the innerHTML, but falls down if there is more than one match (it
will only modify the first occurrence). I suspect that even if I could
find the text around the selected area, this could still fall down for
same reason.
So, I’ve got the selected text via the createTextRange() method.
How do I modify this text and write it back out to the textarea.
