<h2>json數據處理例子</h2>
<p>前提：引入json.js文件，官網提供</p>
<p>訪問成員people.programmers[0].lastName</p>
<p>訪問成員數組的長度people.programmers.length，只有是數組的纔有length屬性</p>
<p>轉化成字符串people.toJSONString()變量jsonStr</p>
<p>轉化成json字符串jsonStr轉成json對象：var jsonObj=eval("("+jsonStr+")");注意要加括號</p>
<h2>使用$.each處理json:</h2>
<div id="show">each輸出結果爲：</div>
<script>
// 注意，這個要放在文件後，否則如果div未加載則獲取不到div用來顯示
$.each(people.programmers,function(idx,item){$("#show").append(" <b>"+item.firstName+"</b>");
});
</script>
</body>
