WebForm MVC is two technical methods of ASP. NET

WebForm is similar to WinForm for visualized operations

MVC is similar to Java and can be operated with multiple codes.

You can right-click the HTML code and choose View in the browser.

12 form elements:

I. Forms

<Form id = "" name = "" method = "post/get" action = "Server responsible for processing"> IDs cannot be duplicated; names can be repeated; get submission has a length limit, the encoded content is visible in the address bar. There is no length limit for post submission and the encoded content is invisible.

</Form>

File Upload <input type = "file" name = "" id = ">

<Label for = ""> </label>

<Label> A tag defines a tag for an input element ).

The label element does not present any special effects to users. However, it improves availability for mouse users. If you click Text in the label element, this control is triggered. That is to say, when the user selects the tag, the browser automatically redirects the focus to the form control related to the tag.

<Label> The for attribute of a tag must be the same as the id attribute of the relevant element.

Drop-down list box

<Select name = "" id = "" size = "" multiple = "multiple"> ------ When size = 1, it is a menu;> 1, it is a list; multiple is multiple.

<Option value = "value"> content 1 </option>

<Option value = "value" selected = "selected"> content 2 </option> ------ seleted, set as default

<Option value = "value"> content 3 </option>

</Select>
