表单提交按钮工作，但不在链接中提交（）
[英]Form Submit Button Works, but not Submit() in Link
问题描述
I've done this so often before on different websites, but can't get it to work now. 
我之前在不同的网站上经常这样做，但现在无法让它工作。 I've got a simple form that posts perfectly well using a submit button, but for a specific reason I actually need it to submit via a url link instead. 我有一个简单的表单，使用提交按钮完美地发布，但由于特定原因，我实际上需要通过URL链接提交。 I'm using submit() . 我正在使用submit() 。 The form submits, but the data isn't posting. 表单提交，但数据未发布。
What am I missing? 我错过了什么？
<html>
<body>
<?
if(isset($_POST['bar'])) { echo 'testing button<br>'; }
if(isset($_POST['information'])) {
echo $_POST['information'];
echo '</br>Info successfully posted.';
}
?>
<form action="test.php" method="post" id="fooform">
Hello World.<br>
Select checkbox: <input type="checkbox" id="information" name="information" value="yes">
<input type="submit" name="bar" value="Send"><br>
<a href="test.php" onclick="SubmitForm('fooform');">Confirm and Post</a><br>
<a href="test.php" onclick="this.form.submit();">Post Directly </a>
</form>
<script type="text/javascript">
function SubmitForm(formId) {
var oForm = document.getElementById(formId);
alert("Submitting");
if (oForm) { oForm.submit(); }
else { alert("DEBUG - could not find element " + formId); }
}
</script>
</body>
</html>

The form starts to submit, then the href of the link is followed, and this cancels the form submission. 表单开始提交，然后跟踪链接的href ，这将取消表单提交。
If you are using old-style onclick attributes, then return false; 如果您使用的是旧式onclick属性，则return false; at the end to prevent the default action. 最后阻止默认操作。
You would, however, be better off using a submit button (you are submitting a form). 你会，但是，使用一个提交按钮（ 你提交表单）会更好。 You can use CSS to change its appearance. 您可以使用CSS来更改其外观。

try to submit form with form id in jquery 尝试在jquery中提交带有表单id的表单
<a class="submit">Post Directly </a>
$('a.submit').click(function(){
$('#fooform').submit();
})
