I am trying to use the angular form validations in my form for a blog post, and more specifically a ng-disabled form. For reasons I cannot figure out the submit button is not disabled, where as it should be unless all three input fields are valid. Thanks for the help.
我试图在我的表单中使用角形式验证作为博客文章,更具体地说是禁用ng表格。由于原因,我无法弄清楚提交按钮未被禁用,除非所有三个输入字段都有效,否则应该在哪里。谢谢您的帮助。

You're missing ng-model on every field of your form. Keep in mind when you mention ng-model on any form field at that time ng-model creates the extra objects inside form name object with that specific name attribute which then considered while form validation like $error, $valid, $invalid, etc.
您在表单的每个字段上都缺少ng-model。请记住,当你在任何表单字段中提到ng-model时,ng-model在表单名称对象中创建额外的对象,该对象具有特定的name属性,然后在表单验证时考虑,如$ error,$ valid,$ invalid等。
As your form name is blgoPost, when angular compile this page,it internally creates the object inside the scope of the name of blgoPost. And the all the input fields which has name & ng-model assign to them gets added inside that blgoPost object. But if you don't mention ng-model to the form fields then it will never get added inside the blgoPost form object.
由于您的表单名称是blgoPost,当angular编译此页面时,它会在blgoPost名称的范围内部创建对象。并且所有具有名称&ng-model的输入字段都将添加到blgoPost对象中。但是如果你没有在表单字段中提到ng-model,那么它将永远不会被添加到blgoPost表单对象中。

<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>
