You are probably referencing your form too soon. 您可能过早引用了表单。 If you try and reference a DOM element before it is loaded, then it's going to fail to attach a listener to it. 如果您尝试在加载DOM元素之前引用它,那么它将无法向其附加侦听器。
Instead, either put the selector below your form: 而是将选择器放在表单下方:
<body>
<form id="login" method="post">
<input type="text" name="user">
<input type="submit" value="send">
</form>
<script>
$("#login").submit(function() {
alert("ok");
});
</script>
</body>
Or make sure the DOM is loaded completely using the jQuery ready stuff (This code can go in the <head>
section): 或者确保使用jQuery ready东西完全加载DOM(此代码可以放在<head>
部分中):
$(function() {
$("#login").submit(function() {
alert("ok");
});
});
尝试将事件添加到您的提交功能
$(#id).submit(function(event){});
