java - send parameter from request through json -

how can resend parameter received servlet servlet using json.

here's mean, using way pass parameters servlet

<a href="studentmanagementservlet?page=${page}&isactivated=${isactivated}" > 

but now, wanna make using json, how can reach ${page} , ${isactivated} json?

jsp parses page before sends client, can use ${variables} anywhere in code, including inline in javascript.

to store them javascript object:

var obj = { page: ${page}, isactivated: ${isactivated} }; 

to store them json object:

var jsonobject = { "page" : "${page}", "isactivated": "${isactivated}" }; 

now, if want send different servlet, you'll need attach json objectto post request servlet.

unfortunately can't post requests anchor tag, you'll need either ajax call or form submit jsonobject 1 of values.
