我一整天都在尝试这样做。最后我设法让它工作。我知道这不是最好的方法。

谁能告诉我一个更好的方法。我总共需要12个。它也不需要是复选框。它可以只是一个文本。我的想法来自 com/2006/12/14/using-jquery-to-show-hide-form-elements-based-on-a-checkbox-selection/

最佳答案

如果我没猜错的话,你可以玩玩

<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
var prototype = $('.prototype').clone();

$('.prototype > input[type="checkbox"]').live('click', function() {
if($(this).is(':checked')) {
var clone = prototype.clone();
clone.find('input[type="checkbox"]').attr('checked', false);
$(this).parent('.prototype').append(clone);
} else {
$(this).parent('.prototype').find('.prototype:last').remove();
}
});
});
</script>
</head>

<body>
<form>
<div class="prototype">
<input type="text" name="" maxlength="30" />
<label for="checkbox"> Check to enter another email address:</label>
<input id="checkme" type="checkbox" />
</div>
</form>
</body>
</html>

编辑:这会在当前原型(prototype)中添加一个新的输入/标签/复选框原型(prototype),或者在另一方面移除它的子级。您也可以将 ID 添加到字段。
