Question

<Asp:Button ID=... onclick="openChildWindow()"

<asp:label ID="label1"  ....>

I have a web page containing a button and a label. When I click the button, openCHildWindow() execute:

openChildWindow()
{ //open child window...
//some other functions....
}

in the child windows, there is a textbox where I can enter some thing.
And my problem is: IF i need the child window to transmit the value in textbox to parent window, is it possible for
//some other functions
wait until parent window gets the value from child window?

Thanks.

I’m not sure if you can have the parent window “wait” for the child window, or if you would want to because you will most likely get a “long running script” message, but I know that you can access the parent window from the child using

window.opener

so you should be able to do something like this before you close the child window:

window.opener.document.getElementById('text1').value = myTextboxValue;
window.close();

of maybe even better just call a function in the parent window:

window.opener.ParentWindowFunction(myTextboxValue);
window.close();
