Regular Expression for MM/DD/YYYY in Javascript

Question

I\'ve just written this regular expression in javaScript however it doesn\'t seem to work, here\'s my function:

function isGoodDate(dt){
    var reGoodDate =         


        

Answer 1

Validate (DD-MM-YYYY) format :)

function isGoodDate(dt) {
    var reGoodDate = /^(?:(0[1-9]|[12][0-9]|3[01])[\-.](0[1-9]|1[012])[\-.](19|20)[0-9]{2})$/;
    return reGoodDate.test(dt);
}
