The parent-child page calls each other several ways to summarize:

First: Use window.open () to open a new window

parent page called Child page:

The child page is opened with window.open and the method is called

var AA = window.open ();

Aa. Child ();//child () is a sub-page method

The child page calls the parent page:

Window.opener. The parent ()//Window.opener is actually a form that is opened by window.open.


The second type: using an embedded frame call

For example: <iframe src= "/**.jsp" width= "100%" height=100% name= "Mapframe" ></iframe>

parent page Calling child page

Mapframe. Child ();//mapframe is the name value of the frame in the parent page, and the method

Set the ID:document.getElementById (' Iframeid ') to the IFRAME. CONTENTWINDOW.ABC (); ABC () is a sub-page function

Child page called parent page

Window.parent. Parent ()

The third type: Using window.showModalDialog (), open a new window

ShowModalDialog ('/window.jsp ', window, ' Dialogheight:300px;dialogwidth:600px;status=off ');

Parent page cannot invoke a child page method

Child page called parent page

Window.dialogarguments. Parent ();
