Jquery Ajax submits a form from action to JSP

JSP page: JavaScript code
 

1. VaR clienttel = $ ("# clienttel"). Val ();
2. VaR activityid = $ ("# activityid"). Val ();
3. $. Ajax ({
4. Type: "Post", // sending Method
   
5. URL: "/arweb/Reserve/savecode. Action", // path
   
6. Data: "clienttel =" + clienttel + "& activityid =" + activityid,
7. Success: function (text) {$ ("# randomcode"). Val (text );},
8. Error: function (text) {alert ("sorry, the user ID does not exist. Please enter the correct user ID ");}
10. });

VaR clienttel = $ ("# clienttel "). val (); var activityid = $ ("# activityid "). val (); $. ajax ({type: "Post", // sending Method URL: "/arweb/Reserve/savecode. action ", // path data:" clienttel = "+ clienttel +" & activityid = "+ activityid, success: function (text) {$ (" # randomcode "). val (text) ;}, error: function (text) {alert ("sorry, the user ID does not exist. Please enter the correct user ID ");}});

Action class: Java code

1. Httpservletresponse res = servletactioncontext. getresponse ();
2. Res. Reset ();
3. Res. setcontenttype ("text/html; charset = UTF-8 ");
4. Printwriter PW = res. getwriter ();
6. PW. Print (random );
7. PW. Flush ();
8. PW. Close ();

Httpservletresponse res = servletactioncontext. getresponse (); Res. reset (); Res. setcontenttype ("text/html; charset = UTF-8"); printwriter PW = res. getwriter (); PW. print (random); PW. flush (); PW. close ();

PW. print (random); here the random is the value that action will pass to JSP. In JSP, success: function (text) here the text is the value that receives the data from the action.
