I have a form that contains around 20 input elements,
they have some onclick event on it.
I would like to know how can I get the form element index when the
onclick event fire.
I found no property or method to do so.
I have a form element that looks like this:
<input type="text" onchange=doSomething(this)>
and a function:
function doSomething(theField){
}
I know that within the function I can access properties of the field (e.g. theField.name and theField.value). But how do I access theField's index number in the form's elements[] array -- from the "this" reference that was passed to the function? I.E. if this field is elements[3], how can I get at that 3?
Currently I'm trying to create a menu with a mouseover effect on a link, which causes an image to display. All images are positioned on the same place, so the optical effect is that one image changes all the time. To achieve this I created an unordered list with the links / items in it, and I created a div with the (corresponding) images. On a mouseover event over a link, the index number of the current li element is stored in a variable, and I want to use that variable to select the corresponding image.
(So <li> index:2 corresponds to <img> index:2)
So in 'human language':
on mouseover of li {
var indexNumber = li.indexnumber
change class of img[indexNumber]
}
But I can't get it to work. I managed to store the 'current' indexnumber successfully in a variable:
var indexNumber = $("li").index(this);
But I can't use the variable to select the corresponding <img> I tried:
$('.slidemenuImgbox img:eq(indexNumber)').addClass('slidemenu_show');
But nothing happens
However when I do:
$('.slidemenuImgbox img:eq(1)').addClass('slidemenu_show');
The image with index:1 is changed.

I am trying to wrap <a> tags around text in <li> elements. How can I get the index of the <li> in the <ul>? I tried something like this: $('.tabbed-list li').wrapInner('<a></a>'); That works fine. However, I want to do something like this: $(this).wrapInner('<a href="#' + $(this).index() + '"></a>');
View 1 Replies View RelatedWhat's the best simple way to filter elements by their index similar to the nth-of-type equation an+b , regardless of parent and node type? Something like...
$("input").filter(":nth-of-set(3n+1)")
... to filter every third input element (3n) starting with the first one (+1).
I am trying to find and get the current index in a group of elements like so:
var index = $(attribute).index(this);
However, this returns -1 for all selectors I pass to it in the variable. Why is this? Is there another way to find a div's position within its container easily?

View 1 Replies View RelatedI'm attempting to physically change the index order of the elements returned by a selector.For example, I'm attempting to make it so when someone clicks on a button, it swaps the index position of the element above or below it (depending on which button they press).I tried to assign it using something like $('.draggable :eq(2)').attr('index', 3)But it didn't seem to work. Is there a way to do it using jQuery, or do I have to change it within DOM itself? Or is there another way to do it?

I'm trying to determine a better method of finding the index value of a form element. I need to find it because the JavaScript validation class has a function for validating a single form element, but it requires that the index number of the element in the form be passed in.Currently I am accomplishing this by a function that I wrote which I call for each field I want to validate:
function getIndex(element)
{
for (var i=0; i<document.thisForm.elements.length; i++)

I am trying to get the index of a li with a specific class. I know I'm selecting the right object because I can apply a CSS class to it (eg change border colour) but when I try to get the index it returns -1. But I know the object exists as I can alter it. :-s
jQuery(document).ready(function() {
var active = $("#tertiarynavigation .bordered").get(0);
var num = $("#tertiarynavigation li").index(active);
alert("Index: " + num);

I'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?
I 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.

I'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"
View 1 Replies View RelatedI have a problem with layers. In my example there's a link inside div#msg with 'z-index:1' and a overlay with 'z-index:2'. Now when "mousedown" fires, will change the div#msg z-index value from 1 to 3 to be on Top, so the link become a clickable link.
The question is, it is possible to make the link on top and open it with just one click?
This example can do that but won't open the link!
HTML Code:
Does "document.formName.elementName.disable" work on hidden form text
elements? I have a form with some input fields that are associated with
some hidden text fields and I would like to disable all of the
categories inside the form when the page loads and only enable each
category as it is needed. Code:
I 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+"'/>"};
$("#list1").addRowData(boxNo,myRow);
I'm working with a form that has both static and dynamic form elements (add textbox, etc), and while I can access the static elements via request.form, the dynamic elements cannot be accessed. I have the dynamic elements appended within a div that lies within a table.
Here is the javascript:
Code:
function add3<%=strGoalCount%><%=strObjCount%>() {
var foo = document.getElementById('fooBar<%=strGoalCount%><%=strObjCount%>');
var numi = document.getElementById('theValue');
var num = (document.getElementById('theValue').value -1)+ 2;

So, when you select a country and it retrieves the state/province text input, the jquery css is not applied to it. Is there something I need to add to the code above or to the jquery initialization code here:

<script type="text/javascript">

How can I traverse through all elements' attributes and ids of a given form id ?
I'm creating a news section for a CMS in PHP and mySQL in which I have a text field for the headline and an textarea for the article. Instead of making the user add each article one-at-a-time I would like to know if there's a way to dynamically create/remove these elements with a button?
for instance; at page load the form contains 1 article - it has 1 text field and 1 textarea. The user decides that he wants to add 2 more articles, so he clicks the "add" button twice. Now the form has 3 articles (3 text fields and 3 textareas), each with a unique id (art1_head,art1_txt, art2_head,art2_txt, art3_head,art3_txt).
Then, I also need to have a button or checkbox to remove each article.
Forgive my ignorance. I'm not a js guy, I work in PHP. Is this possible?
