This article mainly introduces the use of the name attribute of the HTML form tag, and finally the difference between name and ID, which is described in this article as a description of the advantages of the name tag, let's take a look at this article now

Let's start by looking at the Name property usage of the HTML form tag:

The Name property in the form is mainly tagged with the form, just like each of us has a name, and when the form has a name, we can use the Request.Form ("name") method to get the data in the form form when we make the Dynamic Web page design!

Look at the example of the form tag Name property:

HTML form with the name attribute:

<form action= "form_action.asp" method= "Get" name= "MyForm" >  <p> Please enter username: <input type= "text" Name= " FName "/></p>  <p> re-enter user name: <input type=" text "name=" lname "/></p> <input type=  " Button "onclick=" Formsubmit () "value=" OK to commit "/></form>

Effect:

The Name property of the form label describes:

1.name property If [], when submitting a form, multiple name values are automatically made into an array submission

The 2.size property is represented by two properties, one of which is the width of the type for text and password,size as visible content, and the other type of input box that behaves as the width of the field in pixels; common usage:

<p>pin:<input type= "text" name= "PIN" maxlength= "2" size= "2"/></p>

Direct layout with MaxLength with the Size property

3. Note that the Size property has compatibility issues, generally do not use, as far as possible to use CSS to control the input width

The following describes the common name property and seldom uses the id attribute:(the difference between name and ID, the advantage of name)

The Name property of the form label was originally intended for identification purposes, but it is now recommended that an ID be used to identify the element according to the specification. But name cannot be substituted for the following purposes:

1. The control name of the form (form), and the submitted data is controlled by the control's name instead of the ID. Because there are many name that correspond to multiple controls at the same time, such as checkbox and radio, the ID must be unique in the full-text file. In addition, the browser sets the request sent to the server according to the name. Therefore, if the ID is used, the server cannot get the data.

The name of the 2.frame and window for specifying target in another frame or window.

The following are common, but it is strongly recommended that you do not use the name attribute with ID:

Anchor points, usually previously written

<a name= "MyName" >

It is now possible to specify with any element ID:

<div id= "myID" >
