- Json字符串转JavaScript对象
<html>
<body>
<h3>通过 JSON 字符串来创建对象</h3>
<p>
First Name: <span id="fname"></span><br />
Last Name: <span id="lname"></span><br />
</p>
<script type="text/javascript">
var txt = '{"employees":[' +
'{"firstName":"Bill","lastName":"Gates" },' +
'{"firstName":"George","lastName":"Bush" },' +
'{"firstName":"Thomas","lastName":"Carter" }]}'; obj = JSON.parse(txt); document.getElementById("fname").innerHTML=obj.employees[1].firstName
document.getElementById("lname").innerHTML=obj.employees[1].lastName
</script>
</body>
</html>
注意：
eval() 函数使用的是 JavaScript 编译器，可解析 JSON 文本，然后生成 JavaScript 对象。必须把文本包围在括号中，这样才能避免语法错误：
var obj = eval ("(" + txt + ")");
