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
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
- <html xmlns="http://www.w3.org/1999/xhtml">
- <head>
- <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
- <script type="text/javascript" src="../js/jquery-1.6.js"></script>
- </head>
- <body>
- <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>
