I have actually two time pickers one is for start Time and another for finish Time, The finish Time need to be constantly greater than start time. I am making use of eonasdan datetimepicker. If start date is greater than end day it need to not allow or we require to get pop. Please aid me out with this

Here"s what i have actually done so far




You are watching: Start time must occur earlier than end time

$("#starttime,#endtime").datetimepicker( format: "HH:mm");var start_time = $("#Start_Time").val();var end_time = $("#End_Time").val();if (Date.parse(start_time) > Date.parse(end_time)) alert("start time need to be smaller");

*

*

function TimePickerCtrl($) var startTime = $("#starttime").datetimepicker( format: "HH:mm" ); var endTime = $("#endtime").datetimepicker( format: "HH:mm", minDate: startTime.data("DateTimePicker").date() ); duty setMinDate() return endTime .data("DateTimePicker").minDate( startTime.data("DateTimePicker").date() ) ; var bound = false; function bindMinEndTimeToStartTime() endTime.on("dp.change", () => bindMinEndTimeToStartTime(); bound = true; setMinDate(); );$(document).ready(TimePickerCtrl);
*

var startDate = Date.parse($("#txtdatetimepicker1").val()); var endDate = Date.parse($("#txtdatetimepicker2").val()); if (startDate >= endDate) alert("Please enter proper date")
*

Disable the past dates than start day in end_time text box. Something prefer this, please replace textbox id together in your html code.

$( "#startDate" ).datepicker( onSelect: function(dateText, inst) $("#endDate").datepicker("option", "minDate", $(this).val()); , minDate: 0);$( "#endDate" ).datepicker( onSelect: function(dateText, inst) if($( "#startDate" ).val() == "") $( "#endDate" ).val(""); ,)

I walk some point with timepicker
