This time I will show you how to operate the Angular template-driven form, and what are the precautions when operating the Angular template-driven form. The following is a practical case, let's take a look.
I won’t go into details about the importance of forms. Angular supports two-way data binding, verification, status management, etc. of forms. Let’s summarize.
Get user input
<p> </p><h1 id="Angular表单">Angular表单</h1>
If you have the above simple form, regardless of its advantages or disadvantages, what are the ways to obtain the form data? Let’s first look at two simple and crude
1) Event $event methods
When listening to an event, pass the entire event payload $event to the event Process function, which will carry various information about the trigger element. Here we listen to the submit event of the form element, pass the entire form information to the processing function, and print it out
通过Angular css 自动添加的class来控制表单样式
input.ng-invalid.ng-touched{ border: 2px solid red; }
查看下效果,表单校验、样式反馈、按钮状态管理、数据获取都很方便。
