jQuery遍历json的方法分析

复制代码 代码如下:

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({
    url: '/path/to/file',
    type: 'GET',
    dataType: 'json',
    data: {param1: 'value1'},
    success: function (obj){
      //遍历obj
    }
})

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("数据有误~");
};

//for in循环
  for(x in obj.bkdata){
    //x表示是下标，来指定变量，指定的变量可以是数组元素，也可以是对象的属性。
    console.log(obj.bkdata[x]);
  }
//元素 each方法
if (obj.status == 1) {
 $(obj.bkdata).each(function(index,item){
  //index指下标
  //item指代对应元素内容
  //this指代每一个元素对象
  //console.log(obj.bkdata[index]);
  console.log(item);
  //console.log($(this));
 });
}else{
 alert("数据有误~");
};
//jquery each方法
$.each( obj.bkdata, function(index,item){
    console.log(item);
});
