I have a page that uses javascript and opens a child window which updates some fields in the parent window.

Now the fields that are updated have a onchange() function I want the child window to call this function when updating the field.

Is this possible using javascript?

EDIT:

My Code:

This is the link that opens the child window:

<a href="javascript:void(0);" style="width:100%; height:125%" onclick="window.open('otherExpenses.php','R开发者_开发知识库atting','width=350,height=550,left=50,top=50,toolbar=1,status=1,');">Open Child</a>

And in the child window, some operations are done with user interaction, then this is how the child is closed:

<a href="javascript:void(0);" onclick="post_value()">Close Child</a>

And the post_value() function:

function post_value()
{
    opener.document.overHeads.overheadOther.value = document.otherExpenses.TextBox27.value;
    opener.document.overHeads.hiddenOther.value = document.otherExpenses.TextBox27.value;
    //here I want to call a function from the parent window that updates some field in the parent window.
    self.close();
}

to answer your question: "Is this possible using javascript?"

yes

you'll need to post some more code if you want a better answer.

If the function belongs to the parent window, you have to attach it to the child window from the context of the parent window:

//w is the child window
w.document.getElementById('theId').onchange(window.somefunction);
