date validation to DD-MON-YY

[kuolung]

hello everyone,

does any of you know any codes out there to validate any types of entry date such as mm/dd/yyyy, ddmmyy, etc...to DD-MON-YY (07-MAR-01).

I found codes that do the other way around, but couldn't find one that does a conversion to DD-MON-YY, when you enter for example, mm/dd/yy

thank you so much!!!

this works:

<script>
function convertDate(field)
{
var str = field.value;
var months = new Array(&quot;JAN&quot;, &quot;FEB&quot;, &quot;MAR&quot;, &quot;APR&quot;, &quot;MAY&quot;, &quot;JUN&quot;, &quot;JUL&quot;, &quot;AUG&quot;, &quot;SEP&quot;, &quot;OCT&quot;, &quot;NOV&quot;, &quot;DEC&quot;
var reg = /^\d{2}\/\d{2}\/\d{4}$/;
var res = /^\d{6}$/;
var ret = /^\d{2}-\w{3}-\d{2}$/;
if(reg.test(str))
{
var s = str.split(&quot;/&quot;
s[0] = parseInt(s[0]);
if(s[0] <= 12)
{
field.value = s[1]+&quot;-&quot;+months[(s[0] - 1)]+&quot;-&quot;+s[2];
}
else{alert('please enter a valid date');field.focus();field.value = '';return false;}
}
else if(res.test(str))
{
var s = new Array(str.substring(0,2), str.substring(2,4), str.substring(4,6));
s[1] = parseInt(s[1]);
if(s[0] <= 12)
{
field.value = s[1]+&quot;-&quot;+months[(s[1] - 1)]+&quot;-&quot;+s[2];
}
else{alert('please enter a valid date');field.focus();field.value = '';}
}
else if(ret.test(str))
{
return true;
}
else
{
alert('please put in a valid date format.');
field.focus();
field.select();
return false;
}
}
</script>

luciddream,

thank you very much. however, when i enter a date value into the text box (mm/dd/yy), it clears out when i hit enter, is there a way to have a date converted automatically right on the text box when i hit enter after entering???

thanksssssssssssss..

well, you could use it on submit of your form...


<form onsubmit=&quot;convertDate(this.fieldname)&quot;> luciddream@subdimension.com

thanks, you're great! i have one more question, hope you don't mind. that is, where do i change in the codes to have a year with only 2-digit instead of 4 right now (DD-MON-YYYY), i really want only DD-MON-YY. thanks a ton!!!!!!
