Accessing Elements
May 17, 2007How can I access to specific element by javascript and not by using the getElementById method.

View 1 RepliesFirstly, I am aware of all the issues that are introduced with frame
pages - this was not my decision - it is just what I have to work
with...
I have a frame page that looks like this
-------------------
| topFrame |
-------------------
| navFrame |
-------------------
| ContentsFrame |
|------------------
Within the contents frame I have a NEW FRAME set which looks like this
--------------------
| | |
|treeFrm | frmDisp |
| | |
--------------------
I know that this is awful. I have a link in the contentsFrame. When I
move over that link, I need to get a layer that already exists in the
frmDisplay to become visible..
When are named elements written with script accessible to script?
<html><head><script type="text/javascript">
function ready() {
alert( document.getElementsByName("div").length );
}
</script></head>
<body onload="ready()">
<script type="text/javascript">
document.open();
document.writeln( "<div name="div"></div>" );
document.close();
</script>
</body></html>
IOW, why are there 0 elements named div at the time the <body>
element's onload handler is invoked? When can I retrieve this named
div from the document hierarchy?
This exercise is necessary since code I have written using the DOM
(that works) has to run on God-forsaken browsers such as IE 5.1 for
Mac whose support for the DOM is spotty at best.
I'm creating a invoice application. In the JSP page user has an option to enter more than one location for each contract. I have created the JSP page. I face problem in calculating the total for the newlocation if user has added a new one. I'm posing my Invoice.jsp page below. Code:
View 1 Replies View RelatedI need to pull data from an iframe, everything is on my domain (no cross-domain issues). This is how the iframe is named.
Code: <iframe ID="search_frame" src="http://www.mysite.com/pnsearch.php"></iframe>
The iframe has a bunch of <span> elements in it. I need to access the innerHTML of the spans, to check for data and use the data elsewhere. Each span has an unique ID assigned to it. What would be the syntax to read this information? I've tried all sorts of document.frames["search_frame"].getElementById("ID").innerHTML variations to no avail.
However, I'm still wondering about my actual problem, which is that I need to initialize some arrays of named elements when the document is loaded so they can be used by other functions used as event handlers. What I have now is that every function that requires
these arrays checks to see whether they have been initialized, and if not initializes them. That seems to be a fairly ugly hack, and I'd like to use a better way if it exists. Does that make sense?
I'm trying to write a script for a website that reads from a database and makes a separate table for each entry in the database. Since the number of entries can change, I want to dynamically create a div for each one, which I can later hide or display based on user selection. However, when I try to access the dynamically created elements by their ID, they return null. Is what I'm trying to do here actually possible?
for(var i = 0; i < tables.length; i ++)
{
var newDiv = document.createElement("div");
newDiv.setAttribute("id", tables[i].name);
newDiv.setAttribute("name", tables[i].name);
newDiv.setAttribute("class", "hidden");

I have 4 checkboxes in my form and wanna change the number (to be displayed) according to the selection made on the ListBox Menu
HTML PART of the code
<select name= "rights" onChange="chk_Count(this);">
<option value = 0 > Admin </option>
<option value = 1> guest </option>
</select>
<input type= "checkbox" name = "add" value = "on">
<input type= "checkbox" name = "edit" value = "on">
<input type= "checkbox" name = "delete" value = "on">
<input type= "checkbox" name = "view" value = "on">
I want that when I select Guest onle checkboxes for "ADD" n "VIEW" should be shown and when Admin is selected all four. but I am able to find out how to access those elements in the form
and change their properties.
I have a problem in accessing all elements with a common id name in ExtJs. In fact, I have a couple of divs with id like:divmic+a number.
That is the code:
Code:
<div id="slideshow" >
<%
for i=0 to 660/23
for j=0 to 380/23
Response.Write "<div id=divmic" & i & j & "
[Code]...
If I try this code, what is inside of "each" instruction works, but if I want to access all those elements having id starts with "divmic", it doesn' work. Why it's happen that think and how to put all those elements into an array, in ExtJs ?
I return json string and loop through the results putting items in Div's and want can't seem to access the class attribute / selector.
$.getJSON(strUrl, function
(data) {
var
items = [];

I'm having trouble accessing some Elements with jQuery after I created them and added them to the HTML. I want to add some Checkboxes to my Site as soon as the user clicks another Checkbox. That works just fine. But if the user clicks on one of these added checkboxes, i want an event to trigger, too. For starters, i just want to alert a message. But this doesnt happen.So, now I think the Elements are added properly to DOM tree. But still, when I click on one of the added input Elements, nothing happens.What am I doing wrong? How can i get jQuery to recognize the Elements I added?

View 2 Replies View RelatedI 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]
So i've got a form that adds an element onto the page. This is working. When I try to remove said elements, that works. But the same 'delete' button doesn't work on elements not generated by javascript.

I call a javascript function in my page load that accesses an iframe and I get an error. But if I wait till the page completely loads and access the iframe through a click event
everything works fine.
I'm trying to set some of the iframe's properties on page load. Can I do this?
Is it possible to take an ASP textbox that has an attribute of
visible='hidden' and make it visible from javascript? I dont want it

So user clicks button 2, which shows story 2, hide stories 1 and 3. (all on the same page).
The issue is that I've been asked to provide a method to directly link to story 2 or 3, which currently isn't possible since you need to load the page, then click the button to show story 2 or 3 (naturally 1 loads by default).
So I'm looking for any method to go right to story 2/3 from a link.
Perhaps I can pass a variable through the URL which executes the function as soon as the new page loads (which would mean a quick double page load but I could handle that)
Here's the function:
var showMe = function(me) {
document.getElementById(me)["style"]["display"] = "block";
}, hideMe = function(me) {
document.getElementById(me)["style"]["display"] = "none";

I'm trying to figure out how to access body if it has no name or ID.
<html>
<head>
<title>blah</blah>
</head>
<body>
<p>example paragraph</p>
<style type="text/javascript">
document.getElementByTagName('body').setAttribute('bgcolor', '#000');
</style>

It didn't work. I also tried both of these:
document.getElementsByTagName('body').setAttribute('bgcolor', '#000');
document.getElementByTagName('body').item(0).setAttribute('bgcolor', '#000');
I'm trying to access a div within another div, but get an error stating that the firstChild object of the div is not an object. The code I am using is as follows:

I'm not an ace JSer by any means--the problem I'm about to pose could easily be solved with pointers in C++ (the language with which I am most familiar), unfortunately that is not an option.I am making a webapp using the google visualization API:URL...My problem may be related to the API, but I think it's more Javascript oriented--the Google group for the API is helpful,I have a function, drawDash(), which declares some elements of the visualization, some filters for the visualization, then binds them together and draws them. Now what I need to do is access the elements of one of those vars, specifically a filter, and add/change properties of it with an HTML form.
I've set up an onclick function for a set of checkboxes in my form that calls another function. The problem I face is that I can't really access the filter correctly.[code]So basically, I want to have a function be able to edit the var serviceSearch from another function.
Is there a way in Javascript to access a field with [] in it for example
destList[]. I need to have this since the field is a listbox and it contains multiple options. it gets posted to the server and handled by PHP. in order to have all the options submitted to the server the name of the field needs to have a [] on the end of it.
I have a page with a link and a DIV with visibility=hidden. The target of the link is to a hidden IFRAME. The link executes a script in the hidden IFRAME. When the user clicks the link, I change the DIV's visibility to visible. Depending on a condition in the script executing in the hidden IFRAME, I want to change the DIV's visibility back to hidden. How would I do this?
document.parentWindow.all("DIV").style.visibility = "hidden"
but it didn't work.
This is probably a ridiculously simple task, but I am new to Javascript, so here goes. Is it possible to get the 'id' (and other attributes) of a 'div' area after I have clicked into it?
