Jsonarray Turn Jsonobject

I have not known the difference between Jsonarray and Jsonobject, and today I finally figured it out.

Jsonarray is an array that contains data with [], Jsonobject is an object, and {} contains data.

Introduce an easy way to build a jsonarray in the foreground

var array=[]; for (int i=0;i<10;i++) {  var item={};  Item.a= "a" +i;  item.b= "B" +i;  Array.push (item); } ajax:params:{data:JSON.stringify (array), type:1}

In the background you can receive:

  String data=request.getparameter ("array");  Jsonarray myarray=jsonarray.fromobject (data);  for (int i=0;i<myarray.size (); i++) {   jsonobject object=myarray.getjsonobject (i);   String a = object.getstring (' a ');   String B = object.getstring (' b ');  }

The above JS created Jsonarray transmission to the background and the background of a comprehensive analysis is a small part of the whole content to share to everyone, I hope to give you a reference, but also hope that we support the script home.
