In most newer browsers you have .toISOString()method, but in IE8 or older you can use the following (taken from json2.jsby Douglas Crockford):
在大多数较新的浏览器中，您有.toISOString()方法，但在 IE8 或更旧的浏览器中，您可以使用以下内容（取自Douglas Crockford 的json2.js）：
// Override only if native toISOString is not defined
if (!Date.prototype.toISOString) {
// Here we rely on JSON serialization for dates because it matches
// the ISO standard. However, we check if JSON serializer is present
// on a page and define our own .toJSON method only if necessary
if (!Date.prototype.toJSON) {
Date.prototype.toJSON = function (key) {
function f(n) {
// Format integers to have at least two digits.
return n < 10 ? '0' + n : n;
}
return this.getUTCFullYear() + '-' +
f(this.getUTCMonth() + 1) + '-' +
f(this.getUTCDate()) + 'T' +
f(this.getUTCHours()) + ':' +
f(this.getUTCMinutes()) + ':' +
f(this.getUTCSeconds()) + 'Z';
};
}
Date.prototype.toISOString = Date.prototype.toJSON;
}
Now you can safely call `.toISOString() method.
现在您可以安全地调用 `.toISOString() 方法。

There's the .toISOString()method on date. You can use that for Browsers with support for ECMA-Script 5. For those without, install the method like this:
有.toISOString()日期的方法。您可以将其用于支持 ECMA-Script 5 的浏览器。对于那些没有支持的浏览器，请安装如下方法：
if (!Date.prototype.toISOString) {
Date.prototype.toISOString = function() {
function pad(n) { return n < 10 ? '0' + n : n };
return this.getUTCFullYear() + '-'
+ pad(this.getUTCMonth() + 1) + '-'
+ pad(this.getUTCDate()) + 'T'
+ pad(this.getUTCHours()) + ':'
+ pad(this.getUTCMinutes()) + ':'
+ pad(this.getUTCSeconds()) + 'Z';
};
}
