Javascript date validation using dd/mm/yy format

[Krazy K]

Can anyone please guide me to a good resource for date validation in Javascript using dd/mm/yy format?
There are many sites using other formats but I have not come across
anything that uses dd/mm/yy.

Thanks in advance

You must be from the UK (just a guess!).

Split the string using date.split()

This should give you the day, month and year in an array assuming that it has been entered in the correct format in the first place. You can use a regular expression to check for that. Then adapt the code that you have found which already checks for the validity of the date, month and year, but in a different order.

If you need more help, post again.

Thank you for responding but I am sorry I did not quite understand the date.split(). I was looking for a resource that has the code already written which does date validation in dd/mm/yy format as opposed to dd/mm/yyyy.

I am just learning javascript and I need to get some date form fields validated. I was hoping to 'borrow' code that has already been written to do this, just don't know where to look for it since a search on google gives too many results.

There is some Date info here. Here is an article on validating dates.

Hi,

Try using this :)

<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 validate() {
        var oInput1 = document.getElementById("txt1");
        if (isValidDate(oInput1.value)) {
            alert("Valid");
        } else {
            alert("Invalid!");
        }

    }
</script>
