CODE:
<div class="form-group">
<label class="control-label" for="content">Content</label>
<textarea name="content" data-ng-model="vm.article.content" id="content" class="form-control" cols="30" rows="10" placeholder="1400 characters long at least" required ng-minlength="1400" ng-maxlength="14000" highlight-on-error></textarea>
<!--counter-->
<br>
<span class="form-help">{{1400-vm.article.content.length}}
Characters</span>
<div ng-messages="vm.form.articleForms.content.$error" role="alert">
<p class="help-block error-text" ng-message="required">Article title is required.</p>
</div>
</div>
状况:
如果ng-messages上的字数过低,我试图在提交时显示错误消息:错误消息没有出现。
我还试图实时更新文本区域的字数。它没有。
我做错了什么?
参考:
angularjs text area character counter
P.S:
我正在使用mean.js
