Question

ASP document.getElementByID

Asked by: chris_desborough

Getting the following error when trying to pick up a page element in an ASP postback. I understood that ASP has access to the DOM but if fails.

Microsoft VBScript runtime error '800a01a8'  - Object required: 'document', fails on this line:

>>   If document.getElementById("omraSection02a").value <> "" Then

Form field is - <textarea name="omraSection02a" id="omraSection02a">  

<%
  '  
   If request.form("SaveAuditsTopButton") = "Save Audits TopButton" Then
  
     
	  dim val1 
	  
	  If document.getElementById("omraSection02a").value <> "" Then
	    val1 = Replace(document.getElementById("omraSection02a").value,"'","''")
	  End If 
   	  
	 
   
    
%>

Hi Chris

Are you using classic ASP or ASP.Net? I know classic ASP cannot reference form fields in this way. If it is a postback then you would simply use:

<%
  ' If request.form("SaveAuditsTopButton") = "Save Audits TopButton" Then
  
     
          dim val1 
          
          If request.form("omraSection02a").value <> "" Then
            val1 = Replace(request.form("omraSection02a").value,"'","''")
          End If

Yes, using Classic ASP.

In that case the code I posted above should work fine. Have you been able to try it?

> I understood that ASP has access to the DOM but if fails.

You understood wrong. Don't mix up server-side code with client-side code.

Thanks sybe, can't believe everything someone tells you.

As to my question, I should make it a bit clearer. There are 2 <forms> on the page. If I submit from the 1st I want to pick up a value if someone has entered data into the 2nd form. Probably clutching at straws but thought I'd ask the question anyhow.

<form action="omradetails.asp" method="post" name="Audits TopButton" id="Audits TopButto
<input name="SaveAuditsTopButton" type="submit" value="Save Audits TopButton">
</form>

<form action="omradetails.asp>" method="post" name="Audits" id="Audits">      
<textarea name="omraSection02a" id="omraSection02a"></textarea>                
</form>

Anyone going to comment further before I delete the question?

 

by: sybePosted on 2009-10-14 at 01:09:22ID: 25568175

You can not do that directly. Only the values which are in the submitted form are going to be posted to the server.

You could do something with javascript at the onsubmit of the form and hidden form values. But that seems a bit strange. Better have a single form with two submit buttons. You can identify on the server which submit button has been pressed if the buttons have a name and a value.

Thanks sybe. Pointed me in the right direction.
