jQuery preventDefault函数不适用于jsfiddle

Question

I cannot get the following simple jQuery to work. I know I am overlooking something, so please help me out. Here is the code at http://jsfiddle.net/Z5waA/ . It's a simple click the button, then alert with jQuery.

Answer 1

preventDefault(e); should be e.preventDefault();

code should be like this,

$('#submitResetPass').bind('click', function(e) {
    e.preventDefault();
    alert("hello");
});

and you need to add jQuery reference.

Answer 2

You had a couple issues. First, the jsFiddle wasn't set for jQuery. Then, your call to preventDefault wasn't correct. It works here: http://jsfiddle.net/jfriend00/v9aVb/ .

$('#submitResetPass').bind('click', function(e) {
    e.preventDefault();
    alert("hello");
});

Answer 3

使用e.preventDefault（）而不是preventDefault（e）。
