How to use getElementById to get the elements in a form

There are many ways of accessing form elements, of which the easiest is by using the cross-browser W3C DOM document.getElementById method. Before we learn more about this method, it would be useful to know something about the Document Object Model (DOM), the concept of HTML nodes or elements, and the concept of containers.

Each time you load an HTML page, the web browser generates an internal representation of the page in the form of an inverted tree structure. Let us look at a simple form. We will use this form later to demonstrate the use of the getElementById method.

.net 4 framework getelementbyid for javascript without clientid

document.getElementById is null

Background I have a Firefox browser with many tabs opened. One of the tabs is displaying a website having data I want to scrape from. I want to take certain data values, compile statistics, and redisplay the information in a newly created popup. The other tabs are unimportant but it would be nice if I could work in others while I am gathering my data (focus moved away from the data window). When focus is on the tab with data, I execute an extension I am building from the tools menu. This starts my output popup window. At the bottom of the popup I have timer START and STOP buttons. When I push the START button, a timer starts controlling a periodic page scrape every few seconds. This webpage with the data is updated in real time via innerHTML which is why I need a timer to scrape the values every few seconds. CurrentlyAnyway, I can locate the window tab that has my data in javascrip.(not sure if this is pertinent or not.) I am confused though how JS knows what tab I am interested in to scrape my data from. I have tried using variants of document.getElementById() but no matter what I do the return is "null". Does somebody know enough to assist? I have taught myself how to do all this in a month so I am nubie all the way. Thanks !Additional Info I have tried the following and all give null returns. var x=window.opener.document.getElementById('active').innerHTML; var x=

Find Control inside a View of Multiview using Javascript (document.getElementById)



i am using the multiview control inside a page and i am trying to find a control using the javascript function document.getElementById. My Problem is that the function returns null cause it cannot find the control. When i open the code of the page from the browser the active view is not rendered so I think thats the reason why I am getting a null value from the function. 

On the HTML code is rendered only the first view or the view that is activated on page load.

Is there any way to find a control inside the view using javascript? or I am doing something wrong?

Thanks a lot.

how to substitute a variable for getElementById("<%=fieldname.ClientID%>").value


in the following function, I am trying to substitute a variable for the fieldname rnRAPORAmount1in the line:

RAP = document.getElementById("<%=rnRAPORAmount1.ClientID%>").value;

I have the fields rnRAPORAmount1 to rnRAPORAmount65 sequentially i.e. 65 fields on my form and need to do validation on each one. The function as is works fine however I'd rather not write it out 65 times. I've been trying to do something like:

var i = 1 where the value of i is determined by which 'this.id' I'm validating

RAP = document.getElementById("<%='rnRAPORAmount' + i.ClientID%>").value;

but nothing works. Thanks a lot for any suggestions!

<asp:RadioButtonList ID="rbRAPType1" runat="server"  RepeatDirection="Horizontal" onClick="return ValidateRAP(this.id);" >
 <asp:ListItem Value="R"> RAP </asp:ListItem>
 <asp:ListItem Value="O"> OR </asp:ListItem>
 <asp:ListItem Value="N"> NA </asp:ListItem>

function ValidateRAP(field) {
 alert("field= " + field);
 var i = 1
 radioButtons = document.getElementsByName(field);
  for (var x = 0; x < radioButtons.length; x++) {
   if (radioButtons[x].checked) {
   alert("You checked " + radioButtons[
