How to build a JSON string from a JSON object

Serializing to JSON in jQuery [duplicate] 11 answers

No need for jQuery here:

var execs = JSON.stringify( window.ob.executives );

Edit

After OP specifying the structure of the variable, I suggest the following (Traversing through two levels of nested objects, extracting the data to add it to an intermediate object, which can then be serialized):

var obj = {};
$.each(window.ob.executives, function( key, val ) {
  $.each( val, function( iKey, iVal ) {
    obj[ iVal ] = iKey;
  });
});
var execs = JSON.stringify( obj );

您可以使用JSON.stringify（JSON对象）函数， 它将JSON对象转换为JSON字符串。

Use this code JSON.stringify(data);

For eg:

   $.ajax({
                    type: "POST",
                    url: "/Item/Create",
                    data: JSON.stringify({ "item": item, "status": status }),
                    dataType: 'json',
                    contentType: 'application/json;',
                success: function (data) {
                    },
                error: function (data) {
                    TestAlert("Error");
                }
            });
