How to check date format with regular expression in input text?

I'd use Datejs or some other validation library as they've been tested and used for awhile, but if you just want some raw regex, here's what I came up with quickly. This regex will work, but it won't check that the year is over a certain reasonable date; it will only check that it's four numbers long.

if(date.search(/([1-9]\d)\.((0[1-9])|(1[0-2]))\.\d{4}/) > -1){
    //do stuff when date is valid
}else{
    //do stuff when date is not valid
}

Try:

function call()
{    
    if ($("#date").val().search((/^\d{2}[.]\d{2}[.]\d{4}$/))>-1) {
        $("#date").css('background-color', '#FF0000'); 
    }
    else {
        alert("good");
    }
}
