问题内容：

我正在尝试在博客文章（尤其是ng禁用形式）的表单中使用角度表单验证。由于某些原因，我无法确定提交按钮没有被禁用，除非所有三个输入字段均有效，否则应该处于应有的状态。谢谢您的帮助。

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">
  <script src="bower_components/angular-route/angular-route.js"></script>
  <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'
});

问题答案：

您在ng-model表单的每个字段中都缺少您。请记住，当你提到ng-model在当时任何形式的字段ng- model创建表单名对象中的额外的对象与特定的name属性，然后考虑而表单验证一样$error，$valid，$invalid，等。

当您的形式name是blgoPost，当角编译该页面时，它在内部创建的名称的范围内的对象blgoPost。并且将具有name＆ng- model分配给它们的所有输入字段添加到该blgoPost对象内部。但是，如果您不提及ng- model表单字段，那么它将永远不会添加到blgoPost表单对象中。

的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>
