1. JS code for comparing date sizes

Copy code The code is as follows:

Start time: To
End time:

{
var startTime = document.getElementById("startTime").value;
var endTime = document.getElementById("endTime").value;
compareCalendar(startTime, endTime);
} // Compare the size
Function Comparedate (CheckstartDate, Checkenddate) {
var arys1 = new array ();
var arys2 = new array ();
if (CheckstartDate! = Null && checkEndDate != null) {
arys2=checkEndDate.split('-'); var edate=new Date(arys2[0],parseInt(arys2[1]-1),arys2[2]);
if(sdate > edit) { > }
}
}

//Judge the date and time size
function compareTime(startDate, endDate) {
if (startDate.length > 0 && endDate.length > ; 0) {
var startDateTemp = startDate.split(" ");
var endDateTemp = endDate.split(" ");

var arrStartDate = startDateTemp[0].split("- ");
var arrEndDate = endDateTemp[0].split("-");

var arrStartTime = startDateTemp[1].split(":");
var arrEndTime = endDateTemp[ 1].split(":");

var allStartDate = new Date(arrStartDate[0], arrStartDate[1], arrStartDate[2], arrStartTime[0], arrStartTime[1], arrStartTime[2 ]);
var allEndDate = new Date(arrEndDate[0], arrEndDate[1], arrEndDate[2], arrEndTime[0], arrEndTime[1], arrEndTime[2]);

if (allStartDate.getTime() >= allEndDate.getTime()) {
alert("startTime cannot be greater than endTime and cannot be passed");
return false;
} else {
alert(" startTime is less than endTime, so it passed");
return true;
}
} else {
alert("The time cannot be empty");
return false;
}
}
//Compare dates and times
function compareCalendar(startDate, endDate) {
if (startDate.indexOf(" ") != -1 && endDate.indexOf(" ") != -1 ) {
//Includes time, date
compareTime(startDate, endDate); ;
} }
}
