以下是我的领域的一个简单示例:
{
key: 'name',
type: 'input',
validators: {
nameValid: {
expression: function(viewValue, modelValue){
var value = modelValue || viewValue;
return (some condition on value);
},
message: '$viewValue + " is not a valid string"'
}
},
templateOptions: {
label: 'Name',
placeholder: 'Name',
options: [],
required: true
},
validation: {
messages: {
required: function(viewValue, modelValue, scope) {
return scope.to.label + ' is required';
}
}
}
},
我为特定条件和必要的字段条件设置了验证消息。但是,如果未满足我的条件或未填写该字段,则不会显示任何错误消息。该字段只是变为红色(应该如此),但是如何让它也显示我的错误消息?

添加错误模板,然后重试,如果您可以提供jsbin链接进行调试,那就更好了。
<script type="text/ng-template" id="custom-messages.html">
<div class="my-messages" ng-messages="options.formControl.$error" ng-if="options.validation.errorExistsAndShouldBeVisible">
<div class="error-message" ng-message="{{::name}}" ng-repeat="(name, message) in ::options.validation.messages">
{{message(options.formControl.$viewValue, options.formControl.$modelValue, this)}}
</div>
</div>
</script>

您可以在app.config函数中将包装器设置为输入字段以显示错误消息。
app.config(function (formlyConfigProvider)({
formlyConfigProvider.setWrapper({
name: 'validation',
types: ['input'],
template:'<formly-transclude></formly-transclude><div ng-messages="fc.$error" ng-if="form.$submitted || options.formControl.$touched" class="error-messages"><div ng-message="{{ ::name }}" ng-repeat="(name, message) in ::options.validation.messages" class="message">{{ message(fc.$viewValue, fc.$modelValue, this)}}</div></div>'
//templateUrl: 'error-messages.html'
});}};
