Pass array data from javascript in browser to spring mvc controller using ajax

Question

I would like to pass an array from javascript in web browser to a Spring MVC controller using AJAX

In javascript, I have

var a = [];
a[0] = 1;
a[1] =         


        

Answer 1

I end up doing this and it works

In js,

var a = [];
a[0] = 1;
a[1] = 2;
a[2] = 3;


$.ajax({
    type : "POST",
    url : "/myurl",
    data : "a="+a,  //multiple array, just add something like "&b="+b ...
    success : function(response) {
       // do something ... 
    },
    error : function(e) {
       alert('Error: ' + e);
    }
}); 

java side, get a class to receive data, using lombok

@Setter @Getter public class MyData { private ArrayList a;
}

then in the controller

@RequestMapping(value = "/repair_info", method = RequestMethod.POST)
public ModelAndView myControl(MyData myData) {
    // get data with myData object
}
