Access To Elements Without IDs
Jun 28, 2004
I've been asked to build a small ecommerce site using this free shopping cart. However, the shopping cart designer did not tag all the elements with IDs. How can I access specific elements such as tables and forms without IDs? Most of the form elements have name attributes. Is there a method to access that? All I want to do is add some styling to the free cart so it integrates into the existing site design. The free cart allows me a header and footer so scripting is available. I can change tables and forms globally with css and tagNames but I would like to access a specific table.

I have html pages with code like
<div>
<script type="text/javascript" src="http://myserver2/mysite/addhtm.js"></script>
</div>
the script adds some html code and random images selected from second server inside an iframe tag in the div tag.I need to examine this added html and image properties in my page using javascript.A search on internet did not help, it says elements inside iframe coming from different domain can not be accessedIs there any workaround or hack available to access iframe contents from page javascript?

I am trying to access elements of one frame to another by doing the following:
Code:
function GetClientId(strid) {
var i = 0;
var eleName;
[code]...
But I have an asp page that is rendered in the frame with the following html and the <a> is not being picked up with the above code:
HTML Code:
<a id="ctl00_btnLogin" tabindex="3" class="button loginbutton" class="loginbutton" onkeypress="return WebForm_FireDefaultButton(event, 'ctl00_btnLogin');" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$btnLogin", "", true, "LoginControl", "", false, true))"><span>Log In</span></a>
Is it because <a> are not part of document.forms? More importantly how would I go through all html tags?

I have a little problem (maybe I'm just to tired to get it -.-). I'm trying to access elements which are descendants of another element. I do it by using
containers = $('.likeReceiver .powermail_radio_inner'); When counting the elements with .length it says, there are three elements. So far everything is working.However, each time I try to access the elements all I get is a message which says "Undefined".

Normally I would just use document.getElementById to get anything I need but here is my problem:
I have a zip code control that I load using AJAX. it has city, state, country, county and zip code. This gets loaded within a business application and at one point you can have both a bill to and ship to address forms on the screen at the same time, loading my zip control with the same fields, same ids and same name. This forced me to now pass in the form name that contains the control.
I need to get to divs and spans within this form. Primarily as you type in a city or zip code, I am doing a hot search with a popup div that shows you results you can quickly choose from. The only time this becomes an issue is the situation I mentioned before when the zip code control is on the screen twice. I am not certain how to access the innerHTML of a span or div by way of the form name. Is this possible and if so what is the proper syntax?
Here is a very basic example at its simplest form of my problem.
<form name="frm_billto" id="frm_billto">
<span id="myspan">Hello</span>
</form>
<form name="frm_shipto" id="frm_shipto">
<span id="myspan">World</span>
</form>
In the above example because the control was loaded twice, I now have 2 spans with the same ID. I want the innerHTML of the each span based on the form they are in.
We wanted one control that we could use throughout the system that we could update in one place and the entire application be updated. Unfortunately we did not anticipate having it load more than once on the page.

I am currently working on an website which consists of 2 sites. Both have the same design (expect for the colors) and both sites have different navigation items (some are the same). I started the page in PHP with classes. Every site is a Site class which has an array of Content classes.Site->showNavi($section); prints out the navigation of the current site, with a navigation item for each Content class in the array. The active ($section) item is highlighted.Site->showContent($section,$subsection); prints out the content.
First i just wanted to use AJAX for the content section but then I realised that I could use it also on getting thenavigation and the content without reloading the page. So i searched the web and decided to use jQuery.
I started with the change site/design links and with the help of an tutorial i quickly managed to get these links work with following code:
$("#site_navi a").click(function(){ var site = $(this).attr('rel');
var cssfile = "/css/"+ site +".css";
var headerimg = "/img/"+ site +"/logo.png";
$("#site_css").attr("href",cssfile);
[Code]....
But it didn't work and after some testing i realised that i can't access the elements (e.g. a.navigationitem) which Igot from the request from "ajax_get_navi.php", because if i write down the navigation in the html code it works.
So, is there a way to get access to these elements? If not what do i have to change in the ajax_get_navi request to get access?

I'm wondering how to get access to each element I selected e.g. by the :has()-Selector. To explain a bit more: I want to select several elements and add to each of them attributes, but a different one to each element. So how can I run through the elements and modify each one?

im very new to jQuery and have a problem I cant solve by myself. I have an ul li list with items that match a later following div - the match is the id. That id is matching another following div by id. All elements are dynamically generated and can vary in depth. I have a working set with onclick fuctions, but I want to make this working in jQuery.

I have a document that contains a child frame with name/id = "help_frame".
From Javascript in the top level document I can access the child frame's
elements using:
var elem = document.frames.help_frame.document.getElementById ("chkSynonym");
but if I try:
var elem = document.frames.help_frame.document.chkSynonym;
the result is 'undefined'. What is wrong with my syntax?

Let's say I have a webpage. The user does something that writes some new HTML code in to the document, code that wasn't there on the initial page load. This new code causes new HTML elements to appear on the page.
Is there any way I can access the new HTML elements thought JQuery?
Standard use of $('#newelement').click(whatever) doesn't appear to work on HTML code generated by an AJAX request. It's like the JQuery "can't see it".

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"

I am trying to display a webpage from another domain and tried to access its elements and I am facing issues with this.
I tried using "iframes" and am facing cross domain issues.
All that I want to do is, set and get the attributes of the elements of the webpage from the other domain (eg: set text field value, get dropdown box values, click button etc)
Is there a way to get this job done?
I thought of browser addons however it will be a browser specific solution.

I have a page I am working and I am having some trouble with: I need to show and hide areas based on a radio selection. I initally started using the show / hide feature in Jquery but the problem is the elements need to be removed but then put back if the user selects the radio buttonagain as it has form elements that have validaion on them. The validation is still trying to validate the form elements becuase they are still on the page but just not showing. This is the radio group the user makes the selection from:
<input name="terms_usr" type="radio" id="terms_usr_1" value="1"/>
<label for="terms_usr_1">Credit Card</label>
<input type="radio" name="terms_usr" id="terms_usr_2" value="2"/>
<label for="terms_usr_2">C.O.D</label>

I have HTML tags stored in XML. I want to be able to use these HTML elements with Javascript, just as you can with elements in document.body. How can it be done? (And don't try and tell me I should use server-side because I have written it all for Javascript and the project is nearly complete minus this and there are practical reasons for not doing this server-side. After all, anything is possible with Javascript!)
Let me explain:
- I have HTML templates such as this [URL]
- I want javascript to populate these templates then add them to my page
- The only way I know javascript can get this kind of data is by parsing XML
- I want to parse the XML then be able to use the HTML elements just like those in document.body
- As far as I'm aware, XML is the only good way of storing data for javascript. I don't want to store it in javascript variables (too much multiline data with " and '). Nor do I want to build it using document.createElement("div")... etc
As someone not yet with any experience in computer science etc, please ignore my poor terminology! However, I'm not a beginner when it comes to javascript.
Here's the script concerned but I doubt it'll help you understand my problem: [URL]

I've got a page that creates a new div and assigns it a new div id (via a counter) and adds it to the page via the DOM.
I'm trying to duplicate a particular div based on user selection and need to pass it's div id to the duplicate function.
I can't figure out how to either print the div id to screen or enable it to be passed back to the function.
Manually its fine : onClick="dupDivCont('stuff3')" and it just duplicates the div with that id.
Is there any way to get the div id into that onclick function to replace 'stuff3'?
