Calling methods between JavaScript parent-child forms _javascript Tips

The example in this article describes the invocation method between JavaScript parent-child forms. Share to everyone for your reference. Specifically as follows:

If you want to open a new window, use the window.open () method.

If you want to close your own window, use the Window.close () method.

A, parent form

To make it easier for the parent window to manipulate the child window, you can define a variable for the window.open () method, for example:

var OpW = window.open ("tests.html", "Popup", "width=300,height=300");

This allows you to close the child window directly by using the Opw.close () method.

If the parent form wants to manipulate the child window elements, the code is as follows:

Copy Code code as follows:

OpW.document.getElementById ("Fartherwindowtxt"). InnerHTML = "Action child window";

Second, Subform

Child windows can use Window.opener to refer to the parent window, as follows:

Copy Code code as follows:

Window.opener.document.getElementById ("Fartherwindowtxt"). innerhtml= child window Operation parent window! ";
