function jm_checkDate(formObj){
if(/^(\d{2})\/\d{2}\/\d{4}$/.test(thisObj.value)){
var ProposedDate = new Date(formObj.value);
var Now = new Date();
if (ProposedDate > Now){
alert("The date you have entered is in the
future.");
formObj.focus();
return false;
}else{
return true;
}
}else{
alert("Incorrect Date Format.\nDate format should be
mm/dd/yyyy");
formObj.focus();
return false;
}
}
<form name="myform" onsubmit="jm_checkDate(this.form.mydate);">
<input type="text" name="mydate" value="08/27/2003"
onblur="jm_checkDate(this);">
</form>
You could use either the ONSUBMIT or the ONBLUR depending on when you
want the check to take place.
This function is part of a larger library I wrote that scans all
formfields onsubmit, but in the rare case that I need it to be a
"stand-alone" function it works that way as well.
Thanks, hope this helps.
