问题描述
如何防止使用jquery提交表单? / p>
$(document).ready(function(){
//选项A
$(#form)。submit(function(e){
e.preventDefault();
});
//选项B
$( #form)。submit(function(e){
stopEvent(e);
});
//选项C
$(#form ).submit(function(){
return false;
});
});
什么可能是错误的?
更新 - 这里是我的HTML:
< form id =formclass =formaction =page2.php方法= POST >
<! - 表单中的标签 - >
< p class =class2>
< input type =submitvalue =好的! />
< / p>
< / form>
这里有什么不对吗?
解决方案
有两点值得注意:
形式
。相反,通过删除#来引用
标签。
//选项A
$(form)。submit(function(e){
e.preventDefault();
});
选项C也可以。我不熟悉选项B
一个完整的例子:
< HTML>
< head>
< script type =text / javascriptsrc =http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js>< / script>
< script type ='text / javascript'>
$(document).ready(function(){
// option A
$(form)。submit(function(e){
alert('submit intercepted ');
e.preventDefault(e);
});
});
< / script>
< / head>
< body>
< form action =http://google.commethod =GET>
搜寻< input type ='text'name ='q'/>
< input type ='submit'/>
< / form>
< / body>
< / html>
How do I prevent a form from submitting using jquery?
I tried everything - see 3 different options I tried below, but it all won't work:
$(document).ready(function() {
//option A
$("#form").submit(function(e){
e.preventDefault();
});
//option B
$("#form").submit(function(e){
stopEvent(e);
});
//option C
$("#form").submit(function(){
return false;
});
});
What could be wrong?
Update - here is my html:
<form id="form" class="form" action="page2.php" method="post">
<!-- tags in the form -->
<p class="class2">
<input type="submit" value="Okay!" />
</p>
</form>
Is there anything wrong here?
解决方案
Two things stand out:
- It possible that your form name is not
form
. Rather refer to the tag by dropping the #. Also the
e.preventDefault
is the correct JQuery syntax, e.g.//option A $("form").submit(function(e){ e.preventDefault(); });
Option C should also work. I am not familiar with option B
A complete example:
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type='text/javascript'>
$(document).ready(function() {
//option A
$("form").submit(function(e){
alert('submit intercepted');
e.preventDefault(e);
});
});
</script>
</head>
<body>
<form action="http://google.com" method="GET">
Search <input type='text' name='q' />
<input type='submit'/>
</form>
</body>
</html>
