如何在AngularJS指令元素上添加验证？

Question

我对一个正在运行的div进行了kendo验证，另一个div我有AngularJS指令，但我无法实现验证并使其成为需要的字段。如何在业务流程名称中创建必填字段？

到目前为止尝试了代码...

div1.html

 <div class="row">
        <div class="form-group col-md-6 fieldHeight">
            <label for="name" class="col-md-5 required">Business Process Name:</label>
            <div class="col-md-7">
                <input type="text" class="form-control" id="name"
                ng-model="processDTO.processLongName"
                placeholder="Process Name" maxlength="256" name="processName"
                data-required-msg="Business Process Name is required" required><span
                class="k-invalid-msg" data-for="processName"></span>
            </div>

        </div>
        <div class="form-group col-md-6 fieldHeight">
            <label for="countries" class="col-md-5 required">Geographic Locations:</label>
            <div class="col-md-7">
                <div multiselect-dropdown-tree ng-model="nonPersistentProcess.geoLocations" disable-children="true"  options="treeviewOptions"></div>
            </div>
        </div>
    </div>
