我正在使用Angular js,其中我有一个文本框外面和一个包含textbox和textarea的ng-repeat。我想检查单击提交按钮时字段是否包含值。我能够实现ng-repeat之外的控件功能,但不确定如何在单击提交按钮时在ng-repeat内实现必要的字段验证。以下是现有代码:
<form name="mainForm" id="createForm" ng-submit="mainForm.$valid && add()" novalidate>
<div ng-controller="testController" ng-init="init()">
<div>
<label>Name :</label>
</div>
<div>
<input type="text" maxlength="150" required ng-model="testName" name="testName" />
</div>
</div>
<span style="color:red" ng-show="submitted == true && mainForm.testName.$error.required">Name is required</span>
<br />
<div class="row">
<div class="form-group ">
<label>Language</label>
<label>Title</label>
<label>Description</label>
</div>
</div>
<div class="row">
<div>
<div ng-repeat="Descriptions in testsWithDescription ">
<div>
<label ng-model="Descriptions.Language">{{Descriptions.Language}}</label>
</div>
<div>
<input type="text" maxlength="150" name="titleValidate[]" ng-model="Descriptions.Title" />
</div>
<div>
<textarea maxlength="500" name="descriptionValidate[]" noresize ng-model="Descriptions.Description"></textarea>
</div>
<div class="form-group col-md-1">
<a style="cursor:pointer"><img ng-src="{{DeleteIcon_url}}" alt="delete image" ng-click="($index == !selectedDeleteIcon) ||testsWithDescription.splice($index,1)" ng-class="{'disabled': $first}" /> </a>
</div>
</div>
</div>
</div>
<input type="submit" value="Submit" ng-click="submitted=true"/>
如何使用角度js对ng-repeat内的控件进行必要的字段验证? 感谢
答案 0 :(得分:3)
您可以使用$index
跟踪ng-repeat
中不同输入的名称。
<div ng-repeat="Descriptions in testsWithDescription ">
<input type="text"
maxlength="150"
name="titleValidate_{{$index}}"
ng-model="Descriptions.Title"
required />
</div>
您现在可以使用AngularJS的常用验证,就像您已经做过的那样:mainForm.$valid
。
