Angularjs 使用ng repeat的动态表单验证无效

我正在进行动态表单验证，如下所示：

<form role="form" name="myForm">
    <div class="row" ng-repeat="field in fields">
        <div class="form-group">
            <input type="text" class="form-control" placeholder="{{field.title}}" name="formData[field.name]" ng-model="formData[field.name]" required ng-minlength=5 ng-maxlength=20>
            <div class="error">
                <small class="error" ng-show="myForm.formData[field.name].$error.minlength">
                    {{field.minValidationMessage}}
                </small>
            </div>
        </div>
    </div>
    ...
</form>

    $scope.fields = [{
    name: 'name',
    title: 'Name',
    placeholder: 'Enter product name',
    ...
    },{
    name: 'code',
    title: 'Code',
    placeholder: 'Enter product code',
    ...
    }]

    $scope.formData = {
    name: '',
    code: ''
 };

<small class="error" ng-show="myForm.code.$error.minlength">
    Your name is required to be at least 3 characters
</small>

以下代码在此不起作用：

<small class="error" ng-show="myForm.formData[field.name].$error.minlength">
    {{field.minValidationMessage}}
</small>

{{field.minValidationMessage}

但是，如果没有ng repeat（静态），其工作如下：

<form role="form" name="myForm">
    <div class="row" ng-repeat="field in fields">
        <div class="form-group">
            <input type="text" class="form-control" placeholder="{{field.title}}" name="formData[field.name]" ng-model="formData[field.name]" required ng-minlength=5 ng-maxlength=20>
            <div class="error">
                <small class="error" ng-show="myForm.formData[field.name].$error.minlength">
                    {{field.minValidationMessage}}
                </small>
            </div>
        </div>
    </div>
    ...
</form>

    $scope.fields = [{
    name: 'name',
    title: 'Name',
    placeholder: 'Enter product name',
    ...
    },{
    name: 'code',
    title: 'Code',
    placeholder: 'Enter product code',
    ...
    }]

    $scope.formData = {
    name: '',
    code: ''
 };

<small class="error" ng-show="myForm.code.$error.minlength">
    Your name is required to be at least 3 characters
</small>

您的姓名必须至少包含3个字符

如何在

ng show

中引用

myForm.formData[field.name]

提前感谢。

输入的字段名和验证的字段名不一样，应该是same@harish将输入更正为

formData[field.name]

，这是一个打字错误。但是原始报告的问题仍然存在。请看，angular中不支持动态字段名
