将脚本变量作为参数传递

Question

I've a javascript variable which i need to pass as a parameter to the included file. Ex: var var1 = "test";

Now i need to pass this 'var1' to an include file like this

<%@include file="text.jsp?param1=" + var1 %>

Will this work? Help me out.

Or, is there any other way around without submitting the form, I need to pass this variable data to that included file which is presented in the same jsp.

Answer 1

No, this can't work, because the include will be parsed on the server side, long before the javascript var is available.

Instead, you need to add a request parameter to the page url:

<%@include file="text.jsp?param1=${request('someparam')}" %>

Answer 2

No, it won't work. Your JSP is compiled and run server-side, and the Javascript is executed much later on the client-side.

Answer 3

JS processed after JSP. Learn how server side and client side code is executed
