[Chrisch]

I have created a program in javascript code but it gives the problem when i try to update my database and when i refreshed parent window and close the pop up it give me error 'window.opener.document' is null or not an object. I have created database, when user click the button in popup window the data belongs to that user wiil be update in the database.

In dot syntax, you go downward from parent object to children......window. Opener refers to the window from which your "pop up sprang" document refers to the html page.I'd suggest using document.getElementById() method to find the textbox. Usually like this: window.opener.document.getElementById("TextBoxRateLockDate").

try this to solve the problem :

try
{
if ( window.opener.document )
{
alert('solve the problem ');
}
}
catch(e)
{
alert('error problem not solved ');
}
