How jquery iterates through JSON

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 requests:

$.ajax ({         URL: '/path/to/file ',         type: ' GET ',         dataType: ' JSON ',         data: {param1: ' value1 '},         success : function (obj) {              //traverse obj         }     })  

The returned content is inside the success function, where all the traversal operations are done:

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 ("Incorrect data ~");       

For In loop:

The For In loop for     (x in Obj.bkdata) {         //x is the subscript that specifies the variable, which can be an array element or an object's property.         Console.log (obj.bkdata[x]);     }  

Element each method

if (obj.status = = 1) {         $ (obj.bkdata). each (function (index,item) {//index = subscript             //item refers to the contents of the             corresponding element             // This refers to each element of the object             //console.log (Obj.bkdata[index]);             Console.log (item);             Console.log ($ (this));         });     else{         alert ("Incorrect data ~");       

jquery each method

$.each (Obj.bkdata, function (index,item) {         console.log (item);     });
