var s = '{"AboutToExpire":{"Display":true,"Message":"Several of your subscriptions are about to expire. \u003ca id=\"lnkShowExpiringSubs\" href=\"#\"\u003eView subscriptions\u003c/a\u003e"},"Expired":{"Display":true,"Message":"Your McAfee WaveSecure - Tablet Edition subscription has expired and you've been without protection for 384 days. \u003ca id=\"lnkNotificationRenewNow\" href=\"http://home.mcafee.com/root/campaign.aspx?cid=96035&pk=FAB37CF4-3680-4A87-A253-77E7D48BF6D7&affid=0\"\u003eRenew now\u003c/a\u003e"}}';
var data = eval(s); // this will convert your json string to a javascript object
for (var key in data) {
if (data.hasOwnProperty(key)) { // this will check if key is owned by data object and not by any of it's ancestors
alert(key+': '+data[key]); // this will show each key with it's value
}
}

Parse it back to? You could just iterate over it as the object that it is.
解析回？您可以将其作为对象进行迭代。
Say you defined your JSON object as a variable through a closure or something, or for the sake of example just as a variable hardcoded... IE:
假设您通过闭包或其他方式将 JSON 对象定义为变量，或者仅作为示例硬编码的变量... IE：
var myJSON = "{"AboutToExpire":{"Display":true,"Message":"Several of your subscriptions are about to expire. \u003ca id=\"lnkShowExpiringSubs\" href=\"#\"\u003eView subscriptions\u003c/a\u003e"},"Expired":{"Display":true,"Message":"Your McAfee WaveSecure - Tablet Edition subscription has expired and you've been without protection for 384 days. \u003ca id=\"lnkNotificationRenewNow\" href=\"http://home.mcafee.com/root/campaign.aspx?cid=96035&pk=FAB37CF4-3680-4A87-A253-77E7D48BF6D7&affid=0\"\u003eRenew now\u003c/a\u003e"}}"
with jquery's each() you can just iterate over it like.
使用 jquery 的 each() 你可以像迭代一样迭代它。
$each(myJSON, function(x){document.print(myJSON.AboutToExpire[x].Message);`});
