    jquery - JavaScript new Date() Returning NaN in IE, Safari - Stack Overflow

    programmeradmin11浏览0评论

    I am using highcharts to draw charts and parsing the date with new Date() function. In Chrome and FF, date is parsing fine.

    But in IE and Safari, i am getting NaN and Invalid date format resp.

    Below is the data i am getting from backend in (element.x) array

    2016, 04,05
2016, 04,06
2016, 04,07
2016, 04,08
2016, 04,09
2016, 04,10

    Now, i am converting it to Date object in JavaScript as below:

    //Loop starts
var xAxis = new Date(element.x);
datas.push([Date.UTC(xAxis.getUTCFullYear(),xAxis.getUTCMonth(), xAxis.getUTCDate())]);
//Loop ends

    Now, this operation returns NaN in IE but works very well in chrome as below:

    Chrome

    Array([0]=>140004454) - Unix Time stamp i get

    IE

    Array([0]=>NaN)

    • 1 Once you correctly parse the string, if you want an array of the time values, simply do datas.push(+xAxis), which will coerce the Date to a number, returning its time value. Or use xAxis.getTime() if you want something clearer. – RobG Commented May 3, 2016 at 22:42
    • But the problem was with new Date() function. It was not parsing date correctly. – Gags Commented May 4, 2016 at 1:39
    • Hence why it's a ment, not an answer—I'd already given John a +1. :-) Just thought I'd save you a heap of typing and unnecessarily calling Date.UTC. – RobG Commented May 4, 2016 at 1:56
    • and yes,,, This also worked.. doind +xAxis after correct parsing.. Awesome :) – Gags Commented May 4, 2016 at 4:09
    • 1 Per the the first ment. +xAxis is less to type but perhaps xAxis.getTime() is better for maintenance as it's explicit. Your choice. ;-) – RobG Commented May 4, 2016 at 5:44

    The way new Date(dateString) parses dateString varies for different browsers, with some browsers being more flexible than others.

    The safest way to create your date, is to...

    1. split up your element.x into its ponents
    2. convert those ponents to integer values
    3. create a new date using the syntax new Date(year, month, day)

    So, instead of ...

    var xAxis = new Date(element.x);

    ... create your date like this :

    var xvals = element.x.split(',');
var xAxis = new Date(
    parseInt(xvals[0]),
    parseInt(xvals[1]) - 1,
    parseInt(xvals[2])
);

    That should work in all browsers!
