jQuery遍历json的方法(推荐)
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请求:
$.ajax({
url: '/path/to/file',
type: 'GET',
dataType: 'json',
data: {param1: 'value1'},
success: function (obj){
//遍历obj
}
})
返回的内容在success的函数里面,所有的遍历操作都是在这里面操作的:
for循环:
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 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);
});
jQuery的ajax和遍历json数组代码如下所示:
jQuery.ajax({
type: "POST",
url: "server.json",
dataType:'json',
data: "",
success: function(msg){
var title = "";
jQuery.each(msg,function(key,value){
alert(value.ec_id+" "+value.ec_title);
})
}
});
