Using the inputText function retrieves the value entered in the textbox, while the hidden field value returns the current value.
This is my current code snippet:
if (inputText.value.length != 0) {
if (inputText.value < document.getElementById('<%=HdnDate.ClientID%>').value) {
alert("Please make sure that the date is equal to or later than the Current Date.");
inputText.value = "";
return false;
}
}
If the input date follows the format of d/m/y, you can easily convert it into a date object with this code snippet:
function parseDate(s) {
var b = s.split(/\D+/g);
return new Date(b[2], --b[1], b[0]);
}
This will create a date object corresponding to 00:00:00 on the specified date.
To compare this date with the current date, you need to create a new Date object and set the time to 00:00:00.0:
var today = new Date();
today.setHours(0,0,0,0);
Next, convert the string to a Date object and compare the two dates like this:
var otherDay = parseDate('21/4/2013');
console.log(otherDay + ' is less than ' + today + '?' + (otherDay < today)); // ... true
If your date format is 4-may-2014, then use this modified function:
function parseDate(s) {
var months = {jan:0,feb:1,mar:2,apr:3,may:4,jun:5,
jul:6,aug:7,sep:8,oct:9,nov:10,dec:12};
var b = s.split(/-/g);
return new Date(b[2], months[b[1].substr(0,3).toLowerCase()], b[0]);
}
Give this a shot:
<script type="text/javascript">
var currentDate = new Date();
var currentMonth = currentDate.getUTCMonth();
var currentDay = currentDate.getUTCDate();
var currentYear = currentDate.getUTCFullYear();
var dateArray = "";
var selectedDate = '05/05/2014'; // Enter your desired date here from input
var isValid = false;
splitDate(selectedDate, "/");
if (currentYear >= dateArray[2]) {
if (currentMonth >= dateArray[1]) {
if (currentDay >= dateArray[0]) {
isValid = true;
}
}
}
if (!isValid) {
alert("Make sure the selected date is equal to or greater than today's date.");
}
else {
alert("You're good to go, no issues with the date.");
}
function splitDate(stringToSplit, separator) {
dateArray = stringToSplit.split(separator);
}
</script>
Give this a shot
let inputDate1 = inputText.value;
let elementId = document.getElementById('<%=HdnDate.ClientID%>').value;
let compareDate1 = new Date(inputDate1);
let compareDate2 = new Date(elementId);
if(compareDate1 <= compareDate2)
{
alert("Please make sure the date is equal to or greater than the current date.");
}
Here is a code snippet for you to try:
let currentDate = new Date(); // get the current date
let endDate = inputText.value; // retrieving text box value
let endDateArray = endDate.split('/');
let formattedEndDate = new Date(endDateArray.pop(), endDateArray.pop() - 1, endDateArray.pop());
if (formattedEndDate >= currentDate) {
// execute some code
}
