Jquery Value match Regex
javascript, jquery, match, regex
Solution
- Pass a string to RegExp or create a regex using the `//` syntax
- Call `regex.test(string)`, not `string.test(regex)`
So
jQuery(function () {
$(".mail").keyup(function () {
var VAL = this.value;
var email = new RegExp('^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$');
if (email.test(VAL)) {
alert('Great, you entered an E-Mail-address');
}
});
});
Problem
I am trying to validate the input for E-Mail via JQuery: My JQuery ``` <script> /* <![CDATA[ */ jQuery(function(){ $( ".mail" ).keyup(function() { var VAL = $(this).val(); var email = new RegExp(^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$); if(VAL.test(email)){ alert('Great, you entered an E-Mail-address'); } }); }); /* ]]> */ </script> ``` This won't alert even though I entered example@example.com. I already tried .test() and .match(), what did I do wrong?
