问题
A form on page1.asp submits to page2.asp. Page2 takes say a minute to do it's work.
To the end user, the browser stays on page1 while it waits for the response from page2.
How can I show a please wait page instead - is the best way just using javascript to change page1 to say Please Wait when the submit button is pressed?
回答1:
You need to just display your Please Wait onClick when the user browses to the next page, and then make sure to set Response.buffer = True in your Page 2. That will prevent any server output from going to the browser until the page is finished processing.
