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

<script type="text/javascript">
var cities = new Array({"id":1,"name":"nanjing"},{"id":2,"name":"shanghai"});
function add(){
var added = "";
$.each(cities,function(n, value){
//n表示下标
var str = "";
str = '<option id=' + value.id + ' value='+ '"' + value.name + '">' + value.name + '</option>' + '<br/>';
added += str;

//alert(added);
$("#selector").append(added);
}
function add2(){
var added = '';
for(var i = 0; i < cities.length; i++ ){
var data = "";
for(var k in cities[i]){
if(typeof(cities[i][k])=="function"){
cities[i][k]();
}else{
data += k + "=" + cities[i][k] + ' ';
}
}
added += data;
}
var select = document.getElementById("test");
select.innerHTML = added;
}
$(function(){
$("#add").click(function(){
add();
});
});
</script>
<button id="add">显示select</button><br/><br/>
<select id="selector">
</select>
<div id="test">
</div>
</body>
