我有一个带有数据注释的模型,我是一个动态绑定,它使用剔除模板绑定和映射插件与 viewmodel 绑定。我正在尝试对我的模型进行不显眼的客户端验证。在这种情况下我们如何做到这一点。有什么帮助/建议吗?
public class MyUser
{
[Required]
[StringLength(35)]
public string Username { get; set; }
[Required]
[StringLength(35)]
public string Forename { get; set; }
[Required]
[StringLength(35)]
public string Surname { get; set; }
}
在我看来,我正在使用 ajax 动态模板绑定 MyUser 列表。
public JsonResult TestKnockout()
{
IList<MyUser> myUserList = new List<MyUser>();
myUserList.Add(new MyUser { Username = "ajohn", Surname = "surname" });
myUserList.Add(new MyUser { Username = "ajohn1", Surname = "surname1" });
return Json(myUserList, JsonRequestBehavior.AllowGet);
}
}
看法:
<form id="Userform" action='@Url.Action("Save", "Home")' data-bind="template: {name: 'UserTemplate', foreach:UserList}">
<input type="Submit" name="name" value="Submit" />
</form>
<script id="UserTemplate" type="text/Html">
<input type="text" data-bind="value: Username"></input>
<input type="text" data-bind="value: Forename"></input>
<input type="text" data-bind="value: Surname"></input>
</script>
<script type="text/javascript">
var viewModel = {
UserList: ko.observableArray(new Array()),
Save: function () {
//// reached here means validation is done.
alert("Save");
}
}
ko.applyBindings(viewModel);
$.ajax({
type: 'GET',
url: '../Home/TestKnockout',
contentType: "application/json",
success: function (data) {
$.each(ko.mapping.fromJS(data)(), function () {
viewModel.UserList.push(this);
})
// attach the jquery unobtrusive validator
$.validator.unobtrusive.parse("#Userform");
// bind the submit handler to unobtrusive validation.
$("#Userform").data("validator").settings.submitHandler = viewModel.Save;
},
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status);
alert(thrownError);
}
});
</script>
