JQuery Validate using addClassRules: What am I missing?
I've put together a snippet of code in ASP.NET MVC in which I'm trying to use the addClassRules methods of jQuery's validator. From what I can tell I'm taking this straight of the examples on
http://docs.jquery.com/Plugins/Validation/Reference
But the page is just submitted it doesn't show any errors. I would like to use the "addClassRules" pattern for validation because I'm writing dynamic forms.
Here's my View.
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>ValidateMyForm</title>
<script src="<%= Url.Content("~/Scripts/jquery-1.4.1.js") %>" type="text/javascript"></script>
<script src="<%= Url.Content("~/Scripts/jquery.validate.js") %>" type="text/javascript"></script>
</head>
<body>
<% using (Htm开发者_StackOverflow中文版l.BeginForm()) { %>
<input type="text" value="" name="customer1" class="customer" />
<input type="text" value="" id="customer2" name="customer2" class="customer" />
<input type="text" name="customer3" class="customer" />
<p>
<input type="submit" name="submit" value="Submit" />
</p>
<% } %>
<script language="javascript" type="text/javascript">
jQuery(document).ready(function () {
// alias required to cRequired with new message
$.validator.addMethod("cRequired", $.validator.methods.required, "Customer name required");
// alias minlength, too
$.validator.addMethod("cMinlength", $.validator.methods.minlength, $.format("Customer name must have at least {0} characters"));
// combine them both, including the parameter for minlength
$.validator.addClassRules("customer", { cRequired: true, cMinlength: 2 });
})
</script>
</body>
</html>
Any suggestions?
UPDATED: Fully functional code...

<p>
<input type="submit" name="submit" value="Submit" />
</p>
<% } %>
<script language="javascript" type="text/javascript">
jQuery(document).ready(function () {

jQuery("#demoform").validate();
})

Never used this validator before, but it looks like your syntax is a bit off. Also, you're not defining cRequired anywhere.
Please note that none of the following has been tested.
First You'll need to define cRequired:
$.validator.addMethod("cRequired", $.validator.methods.required,
"Customer name required");
Next you'll need to add a validator to a class (where "YourClassName" is the class this should apply to.)
jQuery.validator.addClassRules("YourClassName", {
cRequired: true
});
OR
jQuery.validator.addClassRules({
YourClassName: {
cRequired: true
}
});
You'll then need to add the class to your inputs:
<input id="txtOne" type="text" class="YourClassName">
<input id="txtTwo" type="text" class="YourClassName">
<input id="txtThree" type="text" class="YourClassName">
Hope this helps...

So turns out that you MUST have the following line in the jQuery(document).ready() function as well.
jQuery("#demoform").validate();
"demoform" being the name of your Form element. In my case (MVC) I gave it this name as followings...
<% using (Html.BeginForm(null, null, FormMethod.Post, new { id = "demoform" })) { %>
You could try this jQuery validation plugin
加载中,请稍侯......
