這裡我們舉例校驗ListBox兩個規則:
•校驗必選項
•選擇范圍在0~4項
界面代碼:
. 代碼如下:
<form id="form1" runat="server">
<div align="center">
<fieldset style="width: 350px; height: 200px;">
<table border="0" cellpadding="3" cellspacing="3">
<tr>
<td>
請選擇汽車類型:
</td>
</tr>
<tr>
<td>
<asp:ListBox ID="lstCar" runat="server" Rows="5" SelectionMode="Multiple">
<asp:ListItem Value="1" Text="奔馳汽車"></asp:ListItem>
<asp:ListItem Value="2" Text="寶馬汽車"></asp:ListItem>
<asp:ListItem Value="3" Text="奧迪汽車"></asp:ListItem>
<asp:ListItem Value="4" Text="現代汽車"></asp:ListItem>
<asp:ListItem Value="5" Text="豐田汽車"></asp:ListItem>
</asp:ListBox>
</td>
</tr>
<tr>
<td>
<asp:Button ID="btnSubmit" runat="server" Text="提交" />
</td>
</tr>
</table>
</fieldset>
<div id="message" class="alertmsg">
</div>
</div>
</form>
腳本代碼:
. 代碼如下:
<head id="Head1" runat="server">
<title>Recipe17</title>
<script type="text/javascript" src="Scripts/jquery-1.4.1-vsdoc.js"></script>
<script type="text/javascript" src="Scripts/jquery.validate.js"></script>
<script type="text/javascript">
$(function () {
$("#form1").validate({
rules: {
lstCar: { required: true, rangelength: [0, 4] }
},
messages: {
lstCar: { required: "至少選擇一種車!",
rangelength: "選擇的范圍為零到四種車!"
}
},
errorLabelContainer: $("#message")
});
});
</script>
<style type="text/css">
.alertmsg
{
color: #FF0000;
}
</style>
</head>
