dateformat validation in javascript?

Question

function isValidDate(sText) {
    var reDate = /(?:0[1-9]|[12][0-9]|3[01])\/(?:0[1-9]|1[0-2])\/(?:19|20\d{2})/;
    return reDate.test(sText);
}
function validate1() {
    var oInput1 = document.getElementById("txtdate");
    if (isValidDate(oInput1.value)) {
        alert("Valid");
    } else {
        alert("Invalid!");
    }

}

I had written code for dateformat validations in javascript

and I called this function in textbox as onkeypress="return validate1(event);" but it is not firing. It is taking date as well as any data including date.

Better to use a datepicker and set date-format of your wish. — Parkash Kumar

But the function is firing for me.. See the fiddle jsfiddle.net/WP37Q — Ganesh Jadhav

You probably shouldn't use the keyword event in your onkeypress attribute definition, do you have any errors? — Rob M.

change the function definition from function validate1() to function validate1(e) and try again. — zzlalani

Code is firing fine, suggestion use jquery datepicker...

<script type="text/javascript">
    function isValidDate(sText) {
           var reDate = /(?:0[1-9]|[12][0-9]|3[01])\/(?:0[1-9]|1[0-2])\/(?:19|20\d{2})/;
           return reDate.test(sText);
       }
       function validate1() {
           var oInput1 = document.getElementById("txtdate");
           if (isValidDate(oInput1.value)) {
               alert("Valid");
           } else {
               alert("Invalid!");
           }

       }
</script>

    <input type="text" id="txtdate" name="txtdate" onkeypress="return validate1(event)">
