提交表单之前退出页面

Question

In my application I am showing the warning message when the user want to leave the page before submitting the form. I am using window.onbeforeunload() in the script. My application has a Master page.

I have four different views for a single form. I am inserting record in first view itself. When user quits the page I want to make some DB change(deletion of record). That's why I want to call a server side function from the script.

How to do it ? Can anybody suggest something ?

Thanks

Answer 1

尝试在onbeforeunload处理程序中使用jQuery + ajax 。

Answer 2

JavaScript调用的URL应该是具有您需要的onLoad方法的表单。
