The Date.prototype.toISOString method was added in ES5, not in the ES3 document, as follows
This method is not supported in IE6/7/8, and can be fixed as follows
The code copy is as follows:
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()) + '.'
+ pad(this.getUTCMilliseconds()) + 'Z';
}
}
