$(function(){
//1、定義JSON格式的user物件，並在div中輸出
var user={"id":1,"name":"張三","pwd":"123456"};
$("#objDiv").append("ID:"+user.id+"<br/>")
.append("使用者名稱："+user.name+"<br/>")
.append("密碼："+user.pwd+"<br/>");
//2、定義JSON格式的字串陣列，並在ul和select中輸出
var ary=["中","美","俄"];
var $ary=$(ary);
var $arrSel=$("#arrSel");
var $arrUl=$("#arrUl");
$ary.each(function(i){
$arrSel.append("<option value='"+(i+1)+"'>"+this+"</option>")
});
$ary.each(function(){
$arrUl.append("<li>"+this+"</li>");
});
//3、定義JSON格式的user物件陣列，並使用<table>輸出
var users=[{"id":1,"name":"張三","pwd":"123"},{"id":2,"name":"曹操","pwd":"456"},{"id":3,"name":"西施","pwd":"666"}];
var $objArrDiv=$("#objArrDiv");
var $table=$("<table border='1'><tr><td>id</td><td>姓名</td><td>密碼</td></tr></table>");

$table.append("<tr><td>"+this.id+"</td><td>"+this.name+"</td><td>"+this.pwd+"</td></tr>");
});
$objArrDiv.append($table);
});

一、JSON格式的user物件:
<div id="objDiv"></div>
<br> 二、JSON格式的字串陣列:
<select id="arrSel"></select>
<ul id="arrUl"></ul>
三、JSON格式的user物件陣列:
<div id="objArrDiv"></div>
