Valid date format

[elite311]

I'm trying to use java to validate the date format on the input box of my form as YYYY-MM-DD I can get it to work as MM/DD/YYYY but I want the dashes not slashes. Here is what I have come up with but I'm wondering if someone can help me figure out the valid format part or point me to a good tutorial to look at and read. Thanks

 

function checkdate(input){
var validformat=/^\d{4}\-\d{2}\-\d{2}$/
var returnval=false
if (!validformat)
alert("Invalid Date Format. Please correct and submit again.")
else{ 
returnval=true
}
if (returnval==false) input.select()
return returnval
}

Did some more reading & playing with it and the following code works.

 

function checkdate(input){
var validformat=/^\d{4}\-\d{2}\-\d{2}$/
var returnval=false
if (!validformat.test(input.value))
alert("Invalid Date Format. Please correct and submit again.")
else{
returnval=true
}
if (returnval==false) input.select()
return returnval
}
