我有一個項目列表,每個項目都有一個複選框附加到它。我目前使用jQuery表單和驗證插件。我想要使用它,只有當用戶選中複選框時,與該複選框關聯的文本字段纔會生效,否則不需要驗證。驗證基於複選框值的文本字段 - jQuery驗證
以下是演示代碼
<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>

</form>
了jQuery現在用的就是如下
<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>
請corect我,如果我錯了地方......
編輯:
現在我正在使用下面的腳本
<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();
$("input[name='selectArticle[]']:checkbox").click(countChecked);
</script>
它的工作很好,除非當我取消選中,removeClass的東西沒有工作。當我檢查它動態添加'所需的網址'類,但是當我取消選中,不刪除它。難道我做錯了什麼?
確定... onchange事件在此刻似乎也合情合理,因爲我能夠獲取複選框fetched.This的價值值代表一些id。假設我選中的複選框的值爲1,那麼該複選框下的所有輸入文本字段都有名稱,如title1,headline1,dw1 ...等....所以,如何編碼onchange事件,以便我可以添加'required'屬性僅附加到這些複選框的字段。對不起,JavaScript和jQuey neww ...不擅長編碼在這種語言:( –
@ Sunny-看到我的編輯 –
非常感謝sJhonny ....只是糾正我,如果我錯了。我有一個已知的文本$(「#txtName」+ $(「#checkBox」).val())。我可以修改上面的代碼,像這樣。 addClass('required')?? –
