问题描述

I have the following form. I'd like it to be submitted automatically via jQuery when the user makes a selection, without needing to press the submit button. How do I do this?
<form action="" method="post">
<select name="id" id="cars">
<option value="">Choose</option>
<option value="1">Toyota</option>
<option value="2">Nissan</option>
<option value="3">Dodge</option>
</select>
<input type="submit" name="submit" value="Submit">
</form>
adeneo，我尝试了您的建议，但仍然无法正常工作.这是完整的代码，有什么问题吗?
adeneo, I tried your suggestion but it's still not working. Here's the complete code, anything wrong?
<!doctype html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#cars').on('change', function() {
this.form.submit();
});
});
</script>
</head>
<body>
<form action="" method="post">
<select name="id" id="cars">
<option value="">Select...</option>
<option value="1">Toyota</option>
<option value="2">Nissan</option>
<option value="3">Dodge</option>
</select>
<input type="submit" name="submit" value="Submit">
</form>
</body>
</html>
推荐答案
您的表单缺少操作值，该值阻止最后提交表单.但是在中期，您应该更正以下代码:
Your form is missing an action value, which prevents submitting the form at the end. But in the mid-time you should correct this code:
$(document).ready(function() {
$('#cars').on('change', function() {
document.forms[myFormName].submit();
});
});
您还可以通过触发提交"按钮单击事件来提交表单:
You can also submit a form by triggering submit button click event:
$(document).ready(function() {
$('#cars').on('change', function() {
var $form = $(this).closest('form');
$form.find('input[type=submit]').click();
});
});
