[Solved] Validate username as the user types with jQuery and ASP.NET [closed]

by


Try this:

$("input[type=textbox]").keydown(function(){
    if(/^[a-zA-Z0-9- ]*$/.test($(this).val()) == false) {
        alert('Your search string contains illegal characters.');
    }
    if(/\s/g.test($(this).val()) {
        alert("has white-space");
    }
    if(!$(this).val().length >= 8 && !$(this).val().length <= 25) {
        alert("out of range");
    }
});

For the fourth one you need to do it yourself because I don’t have access to your field names etc.
