document.forms[0].submit() not working.

Hi ,
Pls look into the below function thru which i am calling a modal dialog. After the dialog returned true I am calling document.forms[0].submit();But I am getting an error. object expected. Pls help me out . The function is given below.

function fnOpen(targetPage)
{
myObject.value = "emp1";
alert(myObject.value);
var returnstring = showModalDialog('child.jsp', myObject, "dialogHeight:30px; dialogWidth:400px; scroll:no; status:no; unadorned:no; resizable:no; edge:raised; dialogLeft:middle; dialogTop:middle; center:Yes");
alert(returnstring);
if(returnstring)
{
document.forms[0].action="/testworkspace-ViewController-context-
root/testservlet";
document.forms[0].submit();
}
}

<input type="button" name="submit" id="deleteenable" value="DELETE" onclick="fnOpen('child.jsp');" >

 

Is the above input actually enclosed within a form, or is it just as shown?

 

Give the submit button another "name". It's conflicting with the submit() function name. Or remove the name...

<input type="button" id="deleteenable" value="DELETE" onclick="fnOpen('child.jsp');" >
