About HTM new Page Refresh original page problem

For example, there is a homepage index.htm. There are two <iframe name= "a" src= "a.htm" >,<iframe name= "B" src= "b.htm" >

When you click on the Buttom button on page b, function B () {window.open ("c.htm")};

Open a new page c.htm, after doing something (these actions have changed the value of the background database, and these values are related to a.htm),

Click Buttom,function C () {in c.htm

DoSomething, if the c.htm is turned off, the browser is showing index.htm, but we know that one of the <iframe name= "a" src= "a.htm" > Values need to be updated, so close the

<iframe name= "A" src= "a.htm" before c.htm because of this refresh >

Window.close ();

}

How can I refresh <iframe name= "a" src= "a.htm" >?

Function C ()

{

window.opener.parent.frames[' Treeframe '].location.reload ();//It's all right.

Window.opener is for window.open (), so Window.opener get is b.htm

What Window.opener.parent get is index.htm.

}
