JS transmits the object array as a parameter to the backend, which can be obtained by the backend. js backend

Front-end JS Code:

Var conditons = [];
Var test1 = new Object ();
Test1.name = "1 ";
Test1.id = "2 ";
Var test2 = new Object ();
Test2.name = "1 ";
Test2.id = "2 ";
Conditons. push (test1 );
Conditons. push (test2 );
$ (Function (){
$. Ajax ({
Async: "false ",
Type: 'post ',
Url: 'link ',
Data: {name: "123", conditions: JSON. stringify (conditons )},
DataType: 'json ',
Success: function (data ){
Console. log (data );
},
Error: function (XMLHttpRequest, textStatus, errorThrown ){
Alert ("error ");
}
});
});

Important: Convert the object array to a JSON string: JSON. stringify

 

Backend retrieval:

String conditions = request. getParameter ("conditions ");
JSONArray conditionList = JSONArray. fromObject (conditions );
