使用bootstrap後他由他自帶的樣式has-error,想要使用它就會比較麻煩,往常使用jqueyr.validate的話只有使用他本身的樣式了,並且有模型在使用模型驗證更方便點。怎麼解決呢?html
固然你能夠專門寫一個針對此的jquery插件,我以爲蠻麻煩的,喜歡寫插件的研究下吧。前端
首先Nuget獲取一個 MVC EditorTemplates for Bootstrap 3 的組件,有了他之後就有了一些模版,好比比較簡單的一個Text:node
@model objectjquery
<div class="form-group@(Html.ValidationErrorFor(m => m, " has-error"))">ajax
@Html.LabelFor(m => m, new { @class = "control-label" })bootstrap
<div class="controls">ui
@Html.TextBox(this
"",url
ViewData.TemplateInfo.FormattedModelValue,spa
ViewBag.ClearTextField == true ? new { @class = "form-control clear-text-field input-block-level" } : new { @class = "form-control input-block-level" } )
@Html.ValidationMessageFor(m => m, null, new { @class = "help-block" })
</div>
</div>
這樣子之後在使用EditorFor後就會直接輸出bootstrap須要的html,比較方便。
咱們看到裏面已經有了驗證失敗的has-error的處理,第二個問題來了,咱們須要前端驗證,ajax驗證也行啊,還有自定義驗證呢?
因而乎繼續利用MVC自帶的模型驗證,剛纔獲取的組件中有個Validation類,咱們先在裏面添加一個擴展方法用於非強類型
public static MvcHtmlString ValidationError(this HtmlHelper htmlHelper, string field, string error)
{
if (HasError(htmlHelper, ModelMetadata.FromStringExpression(field, htmlHelper.ViewData), field))
return new MvcHtmlString(error);
else
return null;
}
View中便可添加:
<div class="form-group@(Html.ValidationError("Department", " has-error"))">
<label class="control-label" for="DepartmentId">所在部門</label>
<div class="controls">
<span id="deptname"> </span><a id="btnSelectDepartment">選擇部門</a>
<input class="form-control" data-val="true" data-val-required="部門是必需的。" id="DepartmentId" name="DepartmentId" type="hidden" value="">
@Html.ValidationMessage("Department", null, new { @class = "help-block" })
</div>
</div>
最後在腳本中處理ajax提交和回發的處理,不知道用MVC的Ajax.BeginForm能不能更方便點,不過我的以爲這東西不是很靈活,因此繼續用ajaxSubmit及jquery.ajax:
//ready
var $divuserform = $("#divuserform");
$divuserform.dialog({
title: '新建用戶',//.....
});
$("#btnCreateUser").click(function () {
var nodes = zTreeObjleft.getSelectedNodes();
if (nodes.length > 0) {
CreateUserForm($divuserform);
}
})
function CreateUserForm(form) {
var $divuserform = form;
$.ajax({
url: "CreateUser",
success: function (html) {
CreateUserFormSuccessCallback(html, $divuserform);
}
});
}
function InitSelectDepartmentWhenCreateUser() {
$("#btnSelectDepartment").departmentSelection({
onSelected: function (name, id) {
$("#deptname").text(name);
$("#DepartmentId").val(id);
}
});
}
function CreateUserFormSuccessCallback(html, form) {
var $divuserform = form;
$divuserform.children().children().html(html);
$("#divuserform").dialog("open");
var $form = $divuserform.find("form")
InitSelectDepartmentWhenCreateUser();
$form.submit(function () {
$form.ajaxSubmit(function (data) {
if (data == "success") {
$("#divuserform").dialog("close");
$("#divuserform").clearForm();
}
else {
CreateUserFormSuccessCallback(data, form);
}
});
event.preventDefault();
});
}
後臺Action方法中咱們即可爲其補充自定義驗證:
if (!DepartmentId.HasValue)
{
ModelState.AddModelError("Department", "必須選擇部門");
}
if (ModelState.IsValid)
{
user.Id = Guid.NewGuid();
user.CreateTime = DateTime.Now;
if (DepartmentId.HasValue)
{
var dept = new DeptUserRole();
dept.DepartmentId = DepartmentId.Value;
dept.IsMain = true;
dept.RoleId = RoleId.Value;
user.DeptUserRoles.Add(dept);
}
db.Users.Add(user);
await db.SaveChangesAsync();
return Content("success");
}
return View(user);
大體效果:
