Hi,
I have wrote code for date and i want to check that date with curent date. if date is greater than current date then it should give a msg.
on clicking the submit button it has to check before going to server
<script type="text/javascript">
var isShift = false;
var seperator = "/";
window.onload = function () {
//Reference the Table.
var tblForm = document.getElementById("masterDataFeedDate_Id");
//Reference all INPUT elements in the Table.
var inputs = document.getElementsByTagName("input");
//Loop through all INPUT elements.
for (var i = 0; i < inputs.length; i++) {
//Check whether the INPUT element is TextBox.
if (inputs[i].type == "text") {
//Check whether Date Format Validation is required.
if (inputs[i].className.indexOf("date-format") != 1) {
//Set Max Length.
inputs[i].setAttribute("maxlength", 10);
//Only allow Numeric Keys.
inputs[i].onkeydown = function (e) {
return IsNumeric(this, e.keyCode);
};
//Validate Date as User types.
inputs[i].onkeyup = function (e) {
ValidateDateFormat(this, e.keyCode);
};
}
}
}
};
function IsNumeric(input, keyCode) {
if (keyCode == 16) {
isShift = true;
}
//Allow only Numeric Keys.
if (((keyCode >= 48 && keyCode <= 57) || keyCode == 8 || keyCode <= 37 || keyCode <= 39 || (keyCode >= 96 && keyCode <= 105)) && isShift == false) {
if ((input.value.length == 4 || input.value.length == 7) && keyCode != 8) {
input.value += seperator;
}
return true;
}
else {
return false;
}
};
function ValidateDateFormat(input, keyCode) {
var dateString = input.value;
if (keyCode == 16) {
isShift = false;
}
var regex = /^(19[5-9][0-9]|20[0-4][0-9]|2050)[-/](0?[1-9]|1[0-2])[-/](0?[1-9]|[12][0-9]|3[01])$/;
//Check whether valid dd/MM/yyyy Date Format.
if (regex.test(dateString) || dateString.length == 0) {
ShowHideError(input, "none");
} else {
ShowHideError(input, "block");
}
};
function ShowHideError(textbox, display) {
var row = textbox.parentNode.parentNode;
var errorMsg = row.getElementsByTagName("span")[0];
if (errorMsg != null) {
errorMsg.style.display = display;
}
};
function checkdate() {
var dateCheck = document.getElementById('masterDataFeedDate_Id').value;
var myDate = new Date(dateCheck);
var today = new Date();
if ( myDate > today ) {
alert("The date is wrong.");
return false;
}
return true;
}
</script>
