Hi everyone,
On a new project, i would like to prevent users from entering a date earlier than the first day of the month preceding the current month.
To be more precise, today (dd/mm/yy -> 19/11/19) i would like to prevent entering a date earlier than 01/10/19 (dd/mm/yy format).
When using following code. It works.
<!DOCTYPE html>
<html>
<body>
<p>Click the button to display first day of preceding current month.</p>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction() {
var dateMin = new Date();
dateMin.setFullYear(dateMin.getFullYear(), dateMin.getMonth() - 1, 1);
document.getElementById("demo").innerHTML = dateMin;
}
</script>
</body>
</html>
When i click on Try it button, on 19th november 2019, i've got Tue Oct 01 2019 (+ time) displayed.
But when using following code in my .js file :
var dateMin = new Date();
dateMin.setFullYear(dateMin.getFullYear(), dateMin.getMonth() - 1, 1);
$(function () {
$("input[InputTypeCheck='DateSaisieMin']").datepicker({
onSelect: function () { },
dateFormat: 'dd/mm/yy',
minDate: dateMin,
changeYear: true,
changeMonth: true
},
$.datepicker.regional['fr']).attr('readonly', 'readonly');
});
and following code in my .aspx file :
<p>
<label class="LblLibelle">Date</label>
<asp:TextBox ID="txt_dateDeclaration" runat="server" InputTypeCheck="DateSaisieMin" AutoPostBack="true"></asp:TextBox>
<asp:RequiredFieldValidator ID="rfv_dateDeclaration" runat="server" ControlToValidate="txt_dateDeclaration"
Display="Dynamic" ErrorMessage="La date de l'absence est obligatoire" ValidationGroup="ajout">
<label class="zoneObligatoire"> *</label>
</asp:RequiredFieldValidator>
</p>
I was expecting to be unable to select a date in the datepicker prior to 01/10/2019, but this is not the case. The datepicker shows every month since August.
Can someone tell me where I made a mistake ?
Many Thanks to all.
