1、问题背景
有一个json对象，需要将其转换成json字符串
JSON.stringify(obj)
2、实现源码
<!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" />
<title>JSON对象转换成JSON字符串</title>
<script type="text/javascript">
function strToObject()
{
var obj = {"name":"zhangsan","sex":"男","age":"29"};
var str = JSON.stringify(obj);
alert(str);
}
</script>
</head>
<body>
<div id="body_div" style="vertical-align:middle; text-align:center;">
<input type="button" id="btn" value="转换" onclick="strToObject()"/>
</div>
</body>
</html>
