0, In this demonstration you will learn how to create
4, an initialization event for a Web page using
7, Visual InterDev. Open the page you want to add the
11, initialization script to with the Visual InterDev
14, Source Editor. There are two places where you can add
17, initialization code in a Web page. If you add
21, code in a script section that is not included inside
25, of a procedure it will run when the browser
27, reaches that section as it is reading the file. For
31, example, this code sets a variable and then calls
34, msgbox to output the value of the variable. The second
39, place you can add initialization code to is the
42, OnLoad event of the Window object. So, in the
46, script section I can create an event procedure named
49, "window_onload." In the event procedure I can add
60, any VBScript code I want. For example, I can declare
64, another variable "y," assign it a value, and use
71, msgbox to output it. Any code inside the
78, window_onload event procedure will run after the browser is
83, done loading the page and therefore after any
86, other initialization code included in the script
89, section, but not included in a procedure. Let's save
93, this file and view it with the Visual InterDev
96, browser. Notice that the message box from the
104, initialization code in the script section displays first,
108, displaying the value of 5. When I dismiss the
110, message box the message box from the window_onload
114, event runs at the same time that the page is loaded,
117, displaying the value of "hi." So, now you know how
122, to add initialization code to a Web page using
125, the window_onload event.
