角度表单验证ng已禁用，无法工作

Angular form validation ng-disabled not working

本文关键字：工作 表单 验证 ng      更新时间：2023-12-13

我正试图在博客文章的表单中使用角度表单验证，更具体地说，是一个禁用了ng的表单。由于一些原因，我无法确定提交按钮没有被禁用，除非所有三个输入字段都有效，否则它应该被禁用。谢谢你的帮助。

这是我的博客模板

 <div ng-controller='BlgoCtrl'>
  <div class='container'>
    <h1> Teewinot Blgo</h1>
    <div class="row">
      <div class='col-md-12'>
        <form role='form' name='blgoPost' novalidate>
          <div class='form-group'>
          <label for='blgoTitle'>Title</label>
          <input name='title' type="title" class='form-control'  placeholder='Technologies of the Future' required><br>
          <label for='blgoContent'>Content</label>
          <textarea name='content' rows='8' type="content" class='form-control' placeholder='The technical innovations of the future will be diverse and impactful on the individual......' required></textarea><br>
          <label for='blgoPassCode'>PassCode</label>
          <input name='passcode' type="passcode" class='form-control' placeholder='&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;' required><br>
          <button type="submit" class='btn btn-primary' ng-disabled="blgoPost.$invalid">Submit Post</button>
          </div>
        </form>
      </div>
    </div>

这是我的index.html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Teewinot</title>
  <script src="bower_components/angular/angular.js"></script>
  <script src="bower_components/jquery/dist/jquery.js"></script>
  <script src="bower_components/bootstrap/dist/js/bootstrap.js"></script>
  <meta name="viewport" content="width=device-width, initial-scale=1.0">

  <link href="bower_components/bootstrap/dist/css/bootstrap.css" rel="stylesheet">
</head>
<body ng-app="Teewinot">
<ng-include src="'app/templates/partials/navbar.html'"></ng-include>
<ng-view></ng-view> 
<!-- angular module defintion and reoutes -->
<script src="app/js/app.js"></script>
<script src="app/js/routes.js"></script>
<!-- controllers -->
<script src="app/js/controllers/blog.controller.js"></script>
</body>
</html>

这是我的博客控制器

angular.module('Teewinot').controller('BlgoCtrl', function($scope, $http) {
  'use strict'
});

表单的每个字段都缺少ng-model。请记住，当您在任何表单字段上提到ng-model时，ng-model会在具有特定name属性的表单名称对象中创建额外对象，然后在表单验证时考虑这些属性，如$error、$valid、$invalid等。

由于您的表单name是blgoPost，所以在angular编译此页面时，它会在blgoPost名称的范围内内部创建对象。并且所有具有CCD_ 11&分配给它们的ng-model被添加到blgoPost对象内部。但是，如果您没有在表单字段中提及ng-model，那么它将永远不会添加到blgoPost表单对象中。

HTML

<form role='form' name='blgoPost' novalidate="">
    <input name="first" />
    <div class='form-group'>
        <label for='blgoTitle'>Title</label>
        <input name='title' type="title" class='form-control' ng-model="test1" placeholder='Technologies of the Future' required="">
        <br>
        <label for='blgoContent'>Content</label>
        <textarea name='content' rows='8' type="content" ng-model="test2" class='form-control' placeholder='The technical innovations of the future will be diverse and impactful on the individual......' required=""></textarea>
        <br>
        <label for='blgoPassCode'>PassCode</label>
        <input name='passcode' type="passcode" ng-model="test3" class='form-control' placeholder='&#8226;&#8226;&#8226' required="" />
        <br/>
        <button type="submit" class='btn btn-primary' ng-disabled="blgoPost.$invalid">Submit Post</button>
    </div>
</form>
