在我的控制台日志中,数组如下所示:
{"userid":"5502","fullname":"My fullname","email":"sample@yahoo.com","user_access":"real"}
现在在我的ajax上,我有一个服务器发送给应用程序的数据数组的句柄代码:
function handleData(responseData) {
var access = responseData;
console.log(access);
if (access == '"real"') {
alert("Welcome");
location.href = "home.html";
} else {
alert("Your username and password didn\'t match.");
}
}
如何在数组中获取此"user_access":"real"
的具体值并在条件中使用它。
if (access == '"real"') { // What should be the format of access variable?
alert("Welcome");
location.href = "home.html";
}
答案 0 :(得分:4)
function handleData(responseData) {
var response = JSON.parse(responseData);//assuming you are getting the response as a string
var access = response.user_access;
console.log(access);
if (access == "real") {
alert("Welcome");
location.href = "home.html";
} else {
alert("Your username and password didn\'t match.");
}
}//handleData()
通常,我们希望我们的响应是在json(或者我们可以说是' object')形式,以便我们可以轻松访问其内部属性。因此,如果它已经是对象,则不需要使用JSON.parse
。您可以直接访问此类任何属性 - responseData.user_access
。但如果它是字符串形式,则必须先使用JSON.parse()
将字符串解析为JSON(或对象)格式。

如果没有""围绕{}括号然后只做
function handleData(responseData) {
var access = responseData.access;
if (access === 'real') {
alert("Welcome");
location.href = "home.html";
} else {
alert("Your username and password didn\'t match.");
}
}
