我做错了什么导致表单验证停止了吗？当未单击复选框时，我似乎无法验证它。
我们将不胜感激。
<html>
<head>
<script type="text/javascript">
function validateTerms(){
valid = true;
if ( document.application-form.terms.checked == false ){
alert ( "Please accept the terms" );
valid = false;
}
return valid;
}
</script>
</head>
<body>
<form id="application-form" name="application-form" method="post" action=""><br />
<p><input type="checkbox" name="terms" value="terms" /><b> I have read the <a href="terms.php">Terms</a> *</b>. </p>
<input type="submit" value="Submit Application" onsubmit="return validateTerms()">
<input type="reset" value ="Clear Form" onClick="return confirm('Are you sure you want to reset the form?')">
</form>
</body>
</html>
最佳答案
输入按钮没有onsubmit 事件，使用onclick 代替。还有其他问题，例如选择错误等，已解决。见下文
