将变量从 JavaScript 发送到 Java

Question

I've created a game that collects a User's time on the browser with JavaScript. What I'd like to do is grab that JavaScript data and send it to the backend, which is written in Java (I'm using a local server running on Tomcat). How can I accomplish this?

I've looked into AJAX and here is what I've come up with...

          var myTime = // however long it took for user to win game

          var data = {}
          data["myTime"] = myTime;

          $.ajax({
              type : "POST",
              url : "/path-to/hosting/save",
              data : JSON.stringify(data),
              dataType : 'json',
              timeout : 100000,
              contentType:'application/json',
              success : function(data) {
                  console.log("SUCCESS: ", data);
              },
              error : function(e) {
                  console.log("ERROR: ", e);
              },
              done : function(e) {
                  console.log("DONE");
              }
          });

When I finish the game, I receive this error on the console: statusText:"parsererror"

My initial thought was that I didn't form my JSON correctly, but I am not sure. Any help would be appreciated. Thanks in advance!

As your code it seems like myTime is a single value why you store it in array you can pass that as follows

var myTime = // however long it took for user to win game

      //var data = {}
      //data["myTime"] = myTime;

      $.ajax({
          type : "POST",
          url : "/path-to/hosting/save",
          data : JSON.stringify({
            'myTime': myTime                
          }),
          dataType : 'json',
          timeout : 100000,
          contentType:'application/json',
          success : function(data) {
              console.log("SUCCESS: ", data);
          },
          error : function(e) {
              console.log("ERROR: ", e);
          },
          done : function(e) {
              console.log("DONE");
          }
      });
