Answer 1

如果你像这样使用jQuery

$('#btn-show-forgot').click(function(event) {
/* Check Email Value */
var email = $('#email').val();
if (email == ''){
alert('email must not empty')}
});

或尝试这样

$(document).on('click','#btn-show-forgot',function(event){
var email = $('#email').val();
if (email == ''){
alert('email must not empty')}
});

Answer 2

根据需要尝试这个

$('#btn-show-forgot').click(function(event) {
var email = $('#email').val();
if (email == ''){
var r = confirm("Press a button!");
if (r == true) {
window.location = //your landing page
} else {
txt = "You pressed Cancel!";
}
}
});`
