Analysis of jQuery's json Traversal method _ jquery-js tutorial

This article mainly introduces jQuery's method of traversing json, and analyzes jQuery's techniques for Traversing json data in the form of examples, for more information about jQuery's json Traversal method, see the example in this article. We will share this with you for your reference. The details are as follows:

The Code is as follows:

Var obj = {"status": 1, "bkmsg": "\ u6210 \ u529f", "bkdata": ["\ u5415 \ u5c1a \ u5fd7", "1387580400 ", "\ u6dfb \ u52a0 \ u8bb0 \ u5f55"]} {"status": 1, "bkmsg": "\ u6210 \ u529f", "bkdata ": ["\ u5415 \ u5c1a \ u5fd7", "1387580400", "\ u6dfb \ u52a0 \ u8bb0 \ u5f55"]}, {"status": 1, "bkmsg ": "\ u6210 \ u529f", "bkdata": ["\ u5415 \ u5c1a \ u5fd7", "1387580400", "\ u4ec0 \ u4e48 \ u4e5f \ u6ca1 \ u6709"]}

Ajax request:

$. Ajax ({url: '/path/to/file', type: 'get', dataType: 'json', data: {param1: 'value1'}, success: function (obj) {// traverse obj }})

The returned content is in the success function. All traversal operations are performed here:

For Loop:

Var obj = {"status": 1, "bkmsg": "\ u6210 \ u529f", "bkdata": ["\ u5415 \ u5c1a \ u5fd7", "1387580400 ", "\ u6dfb \ u52a0 \ u8bb0 \ u5f55"]} // console. log (obj. length); if (obj. status = 1) {for (var I = 0; I <obj. bkdata. length; I ++) {console. log (obj. bkdata [I]) ;};} else {alert ("data error ~ ");};

For in loop:

// For in loop for (x in obj. bkdata) {// x indicates a subscript to specify a variable. The specified variable can be an array element or an object attribute. Console. log (obj. bkdata [x]);} // element each method if (obj. status = 1) {$ (obj. bkdata ). each (function (index, item) {// index indicates the subscript // item indicates the content of the corresponding element. // this indicates each element object // console. log (obj. bkdata [index]); console. log (item); // console. log ($ (this) ;}) ;}else {alert ("data error ~ ") ;}; // Jquery each method $. each (obj. bkdata, function (index, item) {console. log (item );});
