我是
angularjs的新手,我只是想知道ngMessage’ng-messages’属性可以做什么.
我正在尝试为多个输入[type = text]元素显示一个ngMessage.例如:
<input type="text" id="name1" ng-model="person.name1" />
<input type="text" id="name2" ng-model="person.name2" />
<input type="text" id="name3" ng-model="person.name3" />
<input type="text" id="name4" ng-model="person.name4" />
<div id="error"
ng-messages="person.name1.$error ||
person.name2.$error ||
person.name3.$error ||
person.name4.$error"
ng-show="person.name1.$touched ||
person.name2.$touched ||
person.name3.$touched ||
person.name4.$touched"
ng-include="errorMsg.html"
/>
将显示所有4个输入[type = text]属性的一条验证消息.
最佳答案 尝试以下面的方式使用它: –
<form name="Form_Name">
<label>
Enter your name:
<input type="text"
name="myName"
ng-model="name"
ng-minlength="5"
ng-maxlength="20"
required />
</label>
<pre>myForm.myName.$error = {{ myForm.myName.$error | json }}</pre>
<div ng-messages="myForm.myName.$error" style="color:maroon" role="alert">
<div ng-message="required">You did not enter a field</div>
<div ng-message="minlength">Your field is too short</div>
<div ng-message="maxlength">Your field is too long</div>
</div>
</form>
