一.纯js实现
<script>
var obj = {"player_id":"GS001","event_id":"1","destroy":"97%"};
var props = "";
for(var p in obj){
if(typeof(obj[p])=="function"){
obj[p]();
}else{
props+= p + "=" + obj[p] + " ";
}
}
alert(props);
</script>
二.jQuery实现
1.遍历对象
$(function(){
var tbody = "";
//------------遍历对象 .each的使用-------------
//对象语法JSON数据格式(当服务器端回调回来的对象数据格式是json数据格式，必须保证JSON的格式要求，回调的对象必须使用eval函数进行转化（否则将得不到Object）。本文不作详细介绍服务器端回调的数据问题，我们将直接自定义对象)
var obj =[{"name":"admin","password":"123456"}];
$("#result").html("------------遍历对象 .each的使用-------------");
alert(obj);//是个object元素
//下面使用each进行遍历
$.each(obj,function(n,value) {
alert(n+' '+value);
var trs = "";
trs += "<tr><td>" + value.name +"</td> <td>" + value.password +"</td></tr>";
tbody += trs;
});
$("#project").append(tbody);
});
2.遍历数组
$(function(){ var tbody = ""; //------------遍历数组 .each的使用------------- var anArray = ['one','two','three']; $("#result").html("------------遍历数组 .each的使用-------------"); $.each(anArray,function(n,value) { alert(n+' '+value); var trs = ""; trs += "<tr><td>" +value+"</td></tr>"; tbody += trs; }); $("#project").append(tbody); });
3.遍历List集合
$(function(){ var tbody = ""; //------------遍历List集合 .each的使用------------- var obj =[{"name":"zhangsan","password":"123456"},{"name":"lisi","password":"333333"}]; $("#result").html("遍历List集合 .each的使用"); alert(obj);//是个object元素 //下面使用each进行遍历 $.each(obj,function(n,value) { alert(n+' '+value); var trs = ""; trs += "<tr><td>" +value.name+"</td> <td>" + value.password +"</td></tr>"; tbody += trs; }); $("#project").append(tbody); });
一个完整的例子,向一个select添加元素
