如何在必需和无效上显示不同的消息? [英] how to show different message on required and invalid?

问题描述

你能告诉我如何在必需和无效时显示不同的消息吗?换句话说，使用插件从 json 制作一个表单.其中有一些必需的参数.还有一些我需要验证示例电子邮件".当如果用户没有填写该字段，则用户按下提交"按钮，它会显示此字段是必需的".如果用户填写了值但不是相同的模式，则它会说无效值".我们可以在不同的情况下显示不同的消息.

我用过这个插件https://github.com/Textalk/angular-schema-form/blob/master/docs/index.md#validation-messages我做了这个 plunkerhttp://plnkr.co/edit/ZNJO3x3IqajjdMNStJMF?p=preview

i used this plugin https://github.com/Textalk/angular-schema-form/blob/master/docs/index.md#validation-messages and I make this plunker http://plnkr.co/edit/ZNJO3x3IqajjdMNStJMF?p=preview

angular.module('test',['schemaForm']).controller('FormController', function($scope,$http){
   $scope.schema = {
    type: "object",
    properties: {
      name: { type: "string", minLength: 2, title: "Name", description: "Name or alias" ,required:true,"default": "dddd"},
      "student": { type: "string", title: "studentname", description: "Name or student" ,required:false},

      "email": {
      "title": "Email",
      "type": "string",
       "pattern":"\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*",

      "description": "Email will be used for evil.",
      required:true
    },
      title: {
        type: "string",
        required:true,
        enum: ['dr','jr','sir','mrs','mr','NaN','dj'],

      }
    }
  };

  $scope.form = [
    "*",
    {
      type: "submit",
      title: "Save"
    }
  ];

推荐答案

正如你从 官方 angular-schema-form 文档

默认情况下，所有错误消息都来自架构验证器 tv4，这可能适合您，也可能不适合.如果您在表单定义中提供了一个validationMessage 属性，并且它的值是一个字符串，该字符串将用于任何验证错误.

Per default all error messages comes from the schema validator tv4, this might or might not work for you. If you supply a validationMessage property in the form definition, and if its value is a string that will be used instead on any validation error.

如果你需要更细粒度的控制，你可以提供一个对象，而不是与 tv4 的错误代码匹配的键.参见 tv4.errorCodes

例如

{
  key: "address.street",
  validationMessage: {
    tv4.errorCodes.STRING_LENGTH_SHORT: "Address is too short, man.",
    "default": "Just write a proper address, will you?"   //Special catch all error message
  }
}

您还可以在 formDefaults 中设置全局验证消息，请参阅全局选项.

You can also set a global validationMessage in formDefaults see Global Options.
