验证日期-用户只能选择下个月的日期

Question

I have a datepicker field (SharePoint 2013) in custom list. I am trying to do a validation for the particular date field (DtStartDate). Conditions are: 1) User should not select past dates from current date 2) User should be selecting dates from next month from current date. Example: if date is 4/26/2017, then user should not select any date till 5/26/2017. If they select, I want to show an error message.

I have tried the below code:

var dtStartDate = $("input[title='Start Date Required Field']").val();
// Get today's date
var todaysDate = new Date();
// Create date from input value
if(dtStartDate.length > 0)
{                   
inputStartDate = new Date(dtStartDate);
// call setHours to take the time out of the comparison
if( (inputStartDate.setHours(0,0,0,0) == todaysDate.setHours(0,0,0,0)) || (inputStartDate < todaysDate ) ) {
// StartDate equals today's date or Date is in the Past
msg = msg + "<br/> Demand Start Date should be greater than Today's Date";
}
}   

How to check the validation for the 2nd case? Thanks

Answer 1

Tru将日期添加到日期选择器

Datefrom.MinDate = DateTime.Now.AddDays(60);

Answer 2

hope this will help

 var d = new Date(); // current date var date = d.setMonth(d.getMonth() + 1); // add month to the current date var inputDate = new Date(d.setMonth(d.getMonth() + 2)); // add two months to the current date console.log('comparison date - ' + new Date(date)); console.log('input date - ' + inputDate); if(date < inputDate.getTime()) console.log('valid date'); else console.log('invalid date');
