我有一个项目列表,每个项目都附有一个复选框。我目前正在使用 jQuery 表单和验证插件。我想使用它,以便仅当用户选中该复选框时,才会验证与该复选框关联的文本字段,否则不需要验证。

以下是演示代码

<form action='feeddatabase.php' method=post id='feedlisting'>
<input type=submit value='Submit!' name=submit>

<table border=2>
<input type=text name='title1' size=100 style='display:none' value="Babes with curves are the new rage in Bollywood">
<tr>
<td rowspan="9"><input type='checkbox' class='article_check' name='selectArticle[]' value=1 /></td>
<td colspan="2"><h3><u><a href='http://www.santabanta.com/cinema.asp?pid=47880'>Babes with curves are the new rage in Bollywood</a></u></h3></td>
</tr>
<tr>
<td><b>Url</b></td>
<td><input type=text class='article_req_info' name='url1' size=100 value='http://www.santabanta.com/cinema.asp?pid=47880'>
<input type=text style='display:none' name='blogurl1' size=100 value='http://www.santabanta.com/cinema.asp'>
<input type=text style='display:none' name='blogtitle1' size=100 value="Latest Bollywood news, Movie Review and Previews">
<input type=text style='display:none' name='blogfeedurl1' size=100 value='http://www.santabanta.com/rss/cinema.asp?cat=Mirch Masala'></td>

</tr>
<tr>
<td><b>Author</b></td>
<td><input type=text name='author1' size=100 value=''></td>
</tr>

<tr>
<td><b>Date</b></td><td><input type=text name='date1' size=100 value='2011-7-08'> </td>
</tr>

<tr>
<td><b>Desc</b></td>
<td><input type=text name='desc1' size=100 value="The curve is more powerful than the sword. And the one time sex goddess should know this from her experience...">
<input type=text style='display:none' name='html_content1' value='The curve is more powerful than the sword. And the one time sex goddess should know this from her experience...'><br></td>
</tr>

<tr>
<td><b>Featured</b></td><td><input type='checkbox' name='featuredArticle1' value=1 /></td>
</tr>

<tr>
<td><b>Category</b></td>
<td><select name="category1">
<option value="Technology" >Technology</option>
<option value="Social" >Social</option>
<option value="Entertainment"selected >Entertainment</option>
<option value="Gaming" >Gaming</option>
<option value="News" >News</option>
<option value="Sports" >Sports</option>
<option value="Videos" >Videos</option></select></td>
</tr>

<tr>
<td><u>Tags: </u></td>
<td><input type=text name='tag1' size=100 value='new rage,curves,babes'></td>
</tr>

<tr>
<td><u>Images for the post from Content/Google/Default</u></td>
<td><input type=radio name="group1" checked value='http://media.santabanta.com/newsite/cinemascope/images/sonakshi24_big.jpg' \>
</td>
</tr>

</table>
</form>

我使用的jquery如下

<html> 
<head>

<script type="text/javascript" src="../javascripts/jquery.js"></script>
<script type="text/javascript" src="../javascripts/jquery.form.js"></script>
<script type="text/javascript" src="../javascripts/jquery.validate.js"></script>
<script type="text/javascript" src="../javascripts/jquery.loady.js"></script>


<script type="text/javascript">

/* $("#loader").loady({
url: "sharer.php"
}); */

$(document).ready(function() {
// bind form using ajaxForm

/* $(this).loady({
url: "sharer.php"
}); */


$('.article_check').click(function() {

rules: {
article_info: {
required: true,

};
}
});

});
</script>
</head>
<body>

</body>

</html>

如果我有什么错误的地方,请纠正我......

编辑:

现在正在使用下面的脚本

 <script>

$(document).ready(function(){
$("#feedlisting").validate();
});



function countChecked() {
var n = $("input[name='selectArticle[]']:checked").length;
var v = $("input[name='selectArticle[]']:checked").val();

if(v)
{
alert(v);
alert("url"+v);
$("#url"+v).addClass('required url');
}
else
{

$("#url"+v).removeClass('required url');
}
$("div").text(n + (n <= 1 ? " is" : " are") + " checked!" + " value :" + v);
}
//countChecked();
$("input[name='selectArticle[]']:checkbox").click(countChecked);
</script>

它工作得很好,除了当我取消选中时,removeClass 东西不起作用。当我选中它时,它会动态添加“必需的 url”类,但当我取消选中时,不会删除它。我做错了什么吗?

最佳答案

几个选项:
1.add a custom rule用于验证文本字段;您的验证函数将检查复选框的值,然后才验证文本字段。
2. 将 onchange 事件添加到复选框,这将从相关文本字段中添加/删除类 'required'(请记住,验证规则也可以在使用类属性的标记)

编辑
针对您的问题,这是一个简单的解决方案:

我假设您有一个要更改的文本字段的静态(=提前已知)列表。例如,如果这些字段是 txtNametxtAddress,您的代码可能类似于:

$("#checkBox").change(function () { 
if ($("#checkBox").val() {
//if checkbox is checked- add the 'required' class
$("#txtName").addClass('required');
$("#txtAddress").addClass('required');
}
else {
//if checkbox is unchecked- remove the 'required' class
$("#txtName").rmeoveClass('required');
$("#txtAddress").removeClass('required');
}
});
