The best way to do this is using new Date()
最好的方法是使用 new Date()
Example:
例子：
var stringDate = '2011-09-19T19:49:21+04:00'
var date = new Date(stringDate) // Mon Sep 19 2011 08:49:21 GMT-0700 (PDT)

Use jquery ui date parser.
使用 jquery ui 日期解析器。

This is the best function for parsing dates out of strings that I've had the pleasure to work with in js. And as you added the tag jquery it's probably the best solution for you.
这是从字符串中解析日期的最佳函数，我很高兴在 js 中使用它。当您添加标签 jquery 时，它可能是您的最佳解决方案。

I just wrote a javascript function that works for any date input field. I'm using jquery date picker and it works well with that.
我刚刚编写了一个适用于任何日期输入字段的 javascript 函数。我正在使用 jquery 日期选择器，它可以很好地工作。
<!DOCTYPE html>
<html>
<body>
<p>Click the button to extract characters from the string.</p>
<button onclick="myFunction()">Try it</button>
<p id="enddate"></p>
<p id="startDate"></p>
<script>
function myFunction() {
//var str = document.getElementById("start_date).value;
// var end = document.getElementById("end_date).value;
var str = "2014-11-26";
var end = "2014-11-22";
//first four strings (year) - starting from zero (first parameter), ends at 4th character (second parameter). It excludes the last character.
var year = str.substring(0,4);
var month = str.substring(5,7);//first two characters since 5th. It excludes the 7th character.
var date = str.substring(8,10);//first two character since 8th char. It excludes the 10th character.
var endYear = end.substring(0,4);
var endMonth = end.substring(5,7);
var endDate = end.substring(8,10);
var startDate = new Date(year, month-1, date);
var endDate = new Date(endYear, endMonth-1, endDate);
document.getElementById("enddate").HTML=endDate;
document.getElementById("startDate").HTML=startDate;
if (startDate > endDate) {
alert('start date should be less than end date');
return false;
} else {
alert('date is ok..');
return true;
}
}
</script>
</body>
</html>
