问题描述
您能告诉我如何显示上提交按钮点击。我正在运行程序后收到错误消息的错误消息（当我写必需：true）？我需要在用户提交表单显示错误信息。我使用这个插件 https://github.com/McNull/angular-febworms
Can you please tell me how to show an error message on submit button click ?.I am getting an error message after running the program (when I write required :true). I need to show an error message when a user submits the form. I am using this plugin https://github.com/McNull/angular-febworms
- 我们可以得到选择字段的onchange事件？
在我的例子，当我运行该应用程序会显示一个红色边框。我不想这样。我需要这个，当用户点击提交按钮
In my example a red border is displayed when I run the application. I don't want this. I need this when a user clicks the 'submit' button

不过需要模糊事件来验证或onchange事件？
But need to blur event to validate or onchange event ?
推荐答案
由于您的表单名称是'form.state 和您的字段名为'需要'（这是由方式有点混乱，你可能想改变这种状况），你可以得到关于用下面的前pressions您的验证状态的有用信息的在表单范围的：
Since your form name is 'form.state' and your field name is 'required' (which is a bit confusing by the way, you may want to change that), you can get useful information about your validation state with the following expressions in the scope of your form:
form.state.required.$error // yields something like { "required": true, "pattern": false }
form.state.required.$valid // yields a boolean
form.state.$error
form.state.$valid
我还没有听说过知道是否一种形式已经提交与否的一种方式。我最好的拍摄将增加一些国家为此控制器：
I haven't heard of a way of knowing whether a form has already been submitted or not. My best shot would be to add some state for this in the controller :
$scope.errorShown = false;
$scope.showErrorMessage = function(){
$scope.errorShown = true;
};
而在你的HTML：
And in your HTML :
<div class="form-actions">
<a class="btn btn-primary" ng-disabled="form.state.$invalid" ng-click="(form.state.$valid ? frmCtrl.save() : showErrorMessage())">Save changes</a>
</div>
<div ng-if="errorShown && form.state.$invalid">
Your form is not valid.
</div>
