[英]Angular form validation ng-disabled not working
我正在尝试在我的表单中使用角度表单验证来撰写博客文章,更具体地说是禁用 ng 的表单。 出于某些原因,我无法确定提交按钮没有被禁用,除非所有三个输入字段都有效,否则应该禁用。 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='•••••••••••••••' 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">

<meta charset="utf-8">

<body ng-app="Teewinot">

<script src="app/js/routes.js"></script>

<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, $http) {
'use strict'
});
您在表单的每个字段上都缺少ng-model
。 请记住,当您在任何表单字段上提到ng-model
时, ng-model
会在表单名称对象中创建具有该特定name
属性的额外对象,然后在表单验证时考虑这些对象,例如$error
、 $valid
、 $invalid
等。
由于您的表单name
是blgoPost
,当 angular 编译此页面时,它会在内部创建blgoPost
名称范围内的对象。 并且所有具有name
和ng-model
分配给它们的输入字段都被添加到该blgoPost
对象中。 但是,如果您没有在表单字段中提及ng-model
,那么它将永远不会被添加到blgoPost
表单对象中。
