HTML5已原生支持json的解析，window.JSON.parse()将json格式字符串转换为json对象，window.JSON.stringify()将json对象转换为json格式字符串。
示例：Html代码
<!DOCTYPE HTML>
<html>
<head>
<title>Window.JSON</title>
<meta charset="gb18030">
</head>
<body>
<button type="button" id="btn1">解析json字符串</button>
<button type="button" id="btn2">json对象转换为json字符串</button>
<div id="res">
</div>
<script language="JavaScript">
<!--
var jsonStr = "{\"total\":100,\"data\":[{\"id\":10001,\"name\":\"scott\"},{\"id\":10002,\"name\":\"tiger\"}]}"
var jsonObj = window.JSON.parse(jsonStr)
document.getElementById("btn1").onclick = function() {
var str = "json字符串解析为json对象<br>"
str += "<span>Total:"+jsonObj.total+"</span><br><span>Data:"
for (var i=0i<jsonObj.data.length i++)
{
str += "id:" + jsonObj.data[i].id + ",name:" + jsonObj.data[i].name+"<br>"
}
str += "</span><br>"
document.querySelector("#res").innerHTML = str
}
document.getElementById("btn2").onclick = function() {
var jsonObj = {total:100,data:[{id:10001,name:"scott"},{id:10002,name:"tiger"}]}
var jsonStr = window.JSON.stringify(jsonObj)
var str = "转为json字符串：<br>" + jsonStr
document.querySelector("#res").innerHTML = str
}
//-->
</script>
</body>
</html>
单击“解析json字符串”按钮，结果：
json字符串解析为json对象
Total:100
Data:id:10001,name:scott
id:10002,name:tiger
单击“json对象转换为json字符串”按钮，结果：
转为json字符串：
{"total":100,"data":[{"id":10001,"name":"scott"},{"id":10002,"name":"tiger"}]}
C#如何将php序列化后的字符串转成json字符串 只需要html转码就行了 System.Web.HttpUtility.HtmlEncode(HtmlDecode)方法对字符进行编码(解码)的答题不易，互相理解，您的采纳是我前进的动力，感谢您。希望回答对你有帮助，如果有疑问，请继续追问<html><head>

if(nodeObj)
nodeObj.childNodes[0].nodeValue = jsonObj[property]
}
