javascript - 表单 jquery 防止默认

Question

我想阻止表单提交，但执行其他表单处理程序，preventDefault 停止所有。

举个例子:

<form id="example">
    <input type="text" name="name" />
</form>

<form id="example2">
    <input type="text" name="name2" />
</form>

/* generic form handling */
$('form').submit(function(e) {
    alert('hello');
});

/* 
    specific example 
    i want this handler to prevent the form from submitting normally, but at the same time, i want it to execute the above code with the alert "hello"
*/
$('form#example').submit(function(e) {
    e.preventDefault(); // this stops the generic form handling (above) and standard form submission
});

Answer 1

尝试返回 false(http://api.jquery.com/submit/声明返回 false 将停止提交):

$('form#example').submit(function(e) {
    return false;
});
