Twitterの統合BootstrapとAsp.netMVC3フォーム
Asp.net MVC3とTwitterBootstrapを使用しています。私が欲しいのは、両方を統合することです。私にとっての大きな問題はフォームです。私はHtmlHelperを使用していますが、これは問題です。検証に関しては、次のようなHTMLを生成する必要があります。
<div class="control-group error">
<label for="field" class="control-label">OMG this label is so awesome: </label>
<div class="controls">
<input type="text" name="field" id="field" value="yeah" />
<span class="help-inline">Eventually some error :C</span>
</div>
</div>
これが私のHtmlHelperコードです：
@Html.LabelFor(x => x.Field)
@Html.EditorFor(x => x.Field)
@Html.ValidationMessagesFor(x => x.Field)
問題は、このフィールドに実際にエラーがある場合にのみ、最も外側のdivのクラスエラーを設定したいということです。他の問題は、エラーにスパンタグを使用する方法がわからないことです。 HtmlHelperでメソッドを作成することもできますが、LabelFor、EditorFor、およびValidationMessageForのほとんどすべての機能を再実装することになります。これを行う簡単な方法はありますか？そして、控えめな検証はどうですか？
私は同じ課題に遭遇し、ラベルの助けを借りて（以下を参照）、これが私が得たものです：
<div class="control-group @if (!ViewData.ModelState.IsValidField("Name")) { @Html.Raw("error"); }">
@Html.LabelFor(model => model.Name, new {@class = "control-label"})
<div class="controls">
@Html.EditorFor(model => model.Name)
@Html.ValidationMessageFor(model => model.Name, null, new {@class = "help-inline"})
</div>
</div>
Html.LabelFor実装： https://stackoverflow.com/a/6722082
目立たない検証は試していませんが、アクティブ化する必要があるようです。
globalエラーを探している場合は、次のようなものを使用する必要があります。
@if (ViewData.ModelState.IsValid == false) {
<div class="alert alert-error"><button class="close" dismiss="alert">x</button><!-- some text--></div>
}
実例（フランス語）ここにあります： http：//ws.sherbrow。 fr/auth
プロジェクトのソースコード全体がまもなく利用可能になるはずです（私のプロファイルを参照するか、直接質問してください）。
少し遅い答えですが、私はより良い解決策を提案します、そしてあなたは私の答えを完全に受け入れるべきです;）
TwitterBootstrapMVC を使用します。
1行のコードで、必要なhtmlを正確に生成します。
@Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Field)
グローバルエラーの場合、書き込む必要があるのは次のとおりです。
@Html.Bootstrap().ValidationSummary()
...すべてのエラーがリストされたアラートdivを生成します。クライアント側の検証では、適切なスタイルを設定するために 一部のJavaScript が必要であることに注意してください。
その上、それはあなたのためにすべての目立たない検証タグの世話をします。また、入力/ラベルの完全なカスタマイズを可能にする流暢な構文を提供します...
見てみな！
免責事項：私はTwitterBootstrapMVCの作成者ですBootstrap 3（およびTwitterBootstrapMVC 3）現在TwitterBootstrapMVCを使用するにはライセンスが必要です。
私は自由を取り、フィールドが無効なときにエラークラスをレンダリングするためにSherbrowからのコードをカプセル化する拡張メソッドを作成しました。この拡張メソッドには、強く型付けされ、記述が短いという利点があります。
public static MvcHtmlString ModelStateFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression)
{
var modelMetadata = ModelMetadata.FromLambdaExpression(expression, html.ViewData);
if (html.ViewData.ModelState.IsValidField(modelMetadata.PropertyName))
{
return MvcHtmlString.Empty;
}
return new MvcHtmlString("error");
}
次のJavaScriptをページに追加することで、MVC3検証をBootstrapフレームワークと統合できます（表示）
<script>
$(document).ready(function () {
/* Bootstrap Fix */
$.validator.setDefaults({
highlight: function (element) {
$(element).closest("div.control-group").addClass("error");
},
unhighlight: function (element) {
$(element).closest("div.control-group").removeClass("error");
}
});
var current_div;
$(".editor-label, .editor-field").each(function () {
var $this = $(this);
if ($this.hasClass("editor-label")) {
current_div = $('<div class="control-group"></div>').insertBefore(this);
}
current_div.append(this);
});
$(".editor-label").each(function () {
$(this).contents().unwrap();
});
$(".editor-field").each(function () {
$(this).addClass("controls");
$(this).removeClass("editor-field");
});
$("label").each(function () {
$(this).addClass("control-label");
});
$("span.field-validation-valid, span.field-validation-error").each(function () {
$(this).addClass("help-inline");
});
$("form").each(function () {
$(this).addClass("form-horizontal");
$(this).find("div.control-group").each(function () {
if ($(this).find("span.field-validation-error").length > 0) {
$(this).addClass("error");
}
});
});
});
</script>
さらに、ビュー（たとえば、「Create.cshtml」）で、フォームのフィールドが次のようにフォーマットされていることを確認してください...
<div class="editor-label">
@Html.LabelFor(Function(model) model.Name)
</div>
<div class="editor-field">
@Html.EditorFor(Function(model) model.Name)
@Html.ValidationMessageFor(Function(model) model.Name)
</div>
BrainDonorに関する記事 があり、メインのLabelFor、EditorFor、およびValidationForを使用するだけで正常に実装できました。これをサイト全体のjsに配置しました。次に、control-group divがあることを確認してください。これで、問題ありません。
これが誰かに役立つかどうかはわかりませんが、これを実現するためにM $のjquery.validate.unobtrusive.jsを変更しました。 $ .validator.setDefaults（）によって提供されるデフォルト設定を上書きし、問題を引き起こしていました。 JSファイルをこれに置き換えると、ブートストラップのCSSで機能するように機能するはずです（入力要素とラベルの一部のCSSクラスを除いて、他の変更は必要ありません）。
$ jQval.setDefaults（）が主なものです。残りは私がM $のコードを修正するだけです。
