JavaScript sample code for comparing two dates_javascript skills

The code is very simple, so I won’t go into too much nonsense here, just give me the code:

Copy code The code is as follows:

function checkDate(){

//replace(/-/g, "/") converts the date into long date format based on the validation expression

var sDate = new Date(document.getElementById_x("datetimepickerStart").value.replace(/-/g, "/"));
var eDate = new Date(document.getElementById_x("datetimepickerEnd").value.replace(/-/g, "/"));

if(sDate > eDate)
{
alert("The end date must not be less than the start date!");
Return false;
}
Return true;
}

Isn’t it very simple? Friends, you can play it freely and use it in your own projects.
