Question

我创建了一个包含两个元素的简单表单，我正在尝试配置jquery验证，以便在单击按钮时验证元素。这是一个普通按钮，而不是提交的按钮。

我已经在Visual Studio中的一个空白mvc项目中启动了这个，并确保我有以下库包含

query.js
jquery-ui.js
jquery.validate.js
bootstrap.css
bootstrap.js

我创建的表单只有两个输入控件和一个按钮

<form role="form" class="form-horizontal" id="formtextmatch">
    <fieldset>
        <div class="form-group">
            <label for="text" class="col-sm-3 control-label">Text</label>
            <div class="col-sm-9">
                <textarea required id="text" name="text" 
                     class="form-control has-error" rows="5" 
                     placeholder="enter text to search for"></textarea>
            </div>
        </div>
        <div class="form-group">
            <label for="subtext" class="col-sm-3 control-label">Subtext</label>
            <div class="col-sm-9">
                <input required type="text" id="subtext" name="subtext" 
                     class="form-control" value="Polly" 
                     placeholder="enter subtext to search for" />
            </div>
        </div>
        <div class="form-group">
            <div class="col-sm-offset-2 col-sm-9">
                <input type="button" id="GetCount" name="GetCount" 
                    value="Get Count" class="btn btn-default" />
            </div>
        </div>
    </fieldset>
</form>

我有以下脚本：

    $(document).ready(function() {
        $("#formtextmatch").validate({
            rules: {
                text: "required",
                subtext: "required"
            },
            messages: {
                text: "Text is required",
                subtext: "Subtext is required"
            },
            errorPlacement: function(error, element) {
                error.insertAfter('.form-group');
            },
            highlight: function(element) {
                $(element).closest('.form-group').addClass('has-error');
            },
            unhighlight: function(element) {
                $(element).closest('.form-group').removeClass('has-error');
            }
        });
    });

我正在设置将两个文本框设置为必填字段，并显示错误消息，然后设置css以指示控件无效的错误

现在我在按钮上点击一个非常简单的脚本来验证表格

    $("#GetCount").click(function() {
        if (!$("#formtextmatch").valid()) {
            alert('form is invalid');
            return;
        }
    });

但是，当我单击表单上的按钮时，似乎没有执行验证。

我希望为此http://jsfiddle.net/DarrenGuy/0ttwzgss/

创造一个小提琴

我尝试添加属性＆＃34; required＆＃34;在html元素上，但这似乎也不起作用，我也将按钮单击更改为validate（），但是研究表明你应该使用valid（）而不是validate（）来点击按钮

我相信我已经正确设置了所有内容，但由于验证无效，我希望我错过了一些非常简单和基本的表单来使验证工作。

更新：我被告知小提琴有效，所以问题必定在我项目中我做错了。

这是我配置的捆绑包

    public static void RegisterBundles(BundleCollection bundles)
    {
        bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                    "~/Scripts/jquery-{version}.js"));

        bundles.Add(new ScriptBundle("~/bundles/jqueryui").Include(
                    "~/Scripts/jquery-ui-{version}.js",
                    "~/Scripts/blockUI.js"));

        bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                    "~/Scripts/jquery.validate*"));

        bundles.Add(new ScriptBundle("~/bundles/toastr").Include(
        "~/Scripts/toastr.js"));

        bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                    "~/Scripts/modernizr-*"));

        bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                  "~/Scripts/bootstrap.js",
                  "~/Scripts/respond.js"));

        bundles.Add(new StyleBundle("~/Content/css").Include(
                  "~/Content/bootstrap.css",
                  "~/Content/site.css",
                  "~/Content/toastr.css"
                  ));
        BundleTable.EnableOptimizations = true;
    }
}

                });
        });

    </script>
}

使用此代码，会弹出toastr，但未正确设置控件css以指示错误，或显示验证规则中定义的错误消息

jquery验证客户端无法正常工作
