I have having a lot of trouble getting validation to work on MVC3. It works fine when I just load the page directly, but it does not validate when I use jquery AJAX POST:
This form is loaded using $('#modal-dialog').load('/DartsMVC/Restaurant/Edit/13')
, This is the rendered HTML:
<form action="/DartsMVC/Restaurant/Edit/13" method="post">
<fieldset>
<legend>Restaurant</legend>
<input data-val="true" data-val-number="The field RestaurantID must be a number." data-val-required="The RestaurantID field is required." id="RestaurantID" name="RestaurantID" type="开发者_C百科hidden" value="13">
<div class="editor-label">
<label for="Name">Name</label>
</div>
<div class="editor-field">
<input class="text-box single-line" data-val="true" data-val-required="The Name field is required." id="Name" name="Name" type="text" value="furaibo">
<span class="field-validation-valid" data-valmsg-for="Name" data-valmsg-replace="true"></span>
</div>
<p>
<input type="submit" value="Save" class="ui-button ui-widget ui-state-default ui-corner-all" role="button" aria-disabled="false">
</p>
</fieldset>
</form>
AJAX POST is used by intercepting the form/submit. The modal dialog pops up and closes itself after the post completes. I would like to validate the form before sending the post:
// force change the submit data to an ajax POST (usually 'save', 'delete' button)
$('#modal-dialog').delegate('form', 'submit', function (e) {
e.preventDefault();
var form = $(this);
form.validate(); // does nothing
if (form.valid()) {
$.ajax({
url: form.attr('action'),
type: "POST",
data: form.serialize(),
success: function (data) {
$('#modal-dialog').dialog('close');
},
error: function (jqXhr, textStatus, errorThrown) {
alert("Error '" + jqXhr.status + "' (textStatus: '" + textStatus + "', errorThrown: '" + errorThrown + "')");
}
});
}
});
Did I break something by doing this? .valid()
always returns true.
My web.config has:
<appSettings>
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>
My page source has:
<link href="/DartsMVC/Content/themes/cupertino/jquery-ui-1.8.14.custom.css" rel="stylesheet" type="text/css">
<script src="/DartsMVC/Scripts/modernizr-1.7.min.js" type="text/javascript"></script>
<script src="/DartsMVC/Scripts/jquery-1.5.1.min.js" type="text/javascript"></script>
<script src="/DartsMVC/Scripts/jquery-ui-1.8.14.custom.min.js" type="text/javascript"></script>
<script src="/DartsMVC/Scripts/jquery.unobtrusive-ajax.js" type="text/javascript"></script>
<script src="/DartsMVC/Scripts/jquery.validate.js" type="text/javascript"></script>
<script src="/DartsMVC/Scripts/jquery.validate.unobtrusive.js" type="text/javascript"></script>
And my model has:
[Required]
public string Name { get; set; }
After more research, I think it may have something to do with dynamic controls:
- Since the data-val attributes exist it is not a Form scope issue
- I'll try calling $.validator.unobtrusive.parse('#formid'). If that doensn't work, I'll use this last resort:

Solved
Calling $.validator.unobtrusive.parse($('form')) did the trick. I guess the validator needs to be recreated for dynamic content
