Object does not support this property or method : ERROR -- JAVA SCRIPT

843836Mar 31 2005 — edited May 14 2008
Hi,

whenever Iam changing a value in the drop down box I want to reload my form. So Iam calling the function in the onChange event of my drop down box. But the form is not submitted, it shows Object does not support this property or method as an error.
The code for this placed below..
<html>
<head>
<script language="javascript">

function formSubmit() 
{
document.forms[0].submit();       //or document.regform.submit();
}

</script> 
</head>
<body>

<form method="post" name="regform" action=updatetechinter.jsp>

<select size="1" name="D1" onChange=formSubmit()>
.
.<option>....</option>
.
.
.
</select>
</form>
</body>
</html>

Hi,
I too get the same problem sometimes..
Dont know wat is the reason..

Try running it in Firefox and checking the javascript console when this happens. IE has completely sh1tty error reporting. I'm guessing that your HTML source contains a syntax error that is confusing the browser, or you are using a reserved keyword somewhere in your code. Difficult to say with so little code.

In fire fox the error which I got is
Error: document.regform.submit is not a function
using 
document.forms[0].submit
also give similar error
I think I havnt use any keywords..

The variables and names given in the sample are exactly same as in my code.

This is most definately the result of bad formatting which is screwing up the DOM that the browser is creating. Run your html output through a validator to see if that turns something up (check http://www.w3.org website).

Hi,
Ur code seems to be perfect...but as long as ur getting error...u need to find out other ways to write the same code......in this way it might work....
I would suggest u to try the following code....and hope that it will work...

**********************************************************************
<html>
<head>
<script language="javascript">

function formSubmit()
{
document.regform.action = "updatetechinter.jsp";
document.regform.method = "post" ;
document.regform.submit();
}

</script>
</head>
<body>

<form name="regform" >

<select name="D1" onChange="javascript:formSubmit();">
.
.<option>....</option>
.
.
.
</select>
</form>
</body>
</html>

hi,
make sure that the user defined controls name(like input, buttons, hidden fields... etc) should not affect the method names or property..

E.g

<input type=hidden name="submit" value="formSubmit">

The aboue code, i.e creating an input field of hidden type named as "Submit" , which affects the javascript Submit method.

Whenever I try thro'IE i get amessage OBJEC doesn't support this property or method

You may try to see if you have declare a variable called "submit". If you do change it to something else then you will not be getting the error messages.
