Bootstrap Input Group

Overview

The majority of the features we apply in documents to catch user data are offered by the

<input>

tag.

You are able to without trouble stretch form directions simply by adding in text message, tabs, as well as button groups on each side of textual

<input>

-s.

The many different forms of Bootstrap Input File are established by value of their option attribute.

Next, we'll describe the taken types with regard to this particular tag.

Text message

<Input type ="text" name ="username">

Most likely easily the most prevalent sort of input, which owns the attribute

type ="text"

, is employed whenever we wish the user to deliver a elementary textual information, given that this particular feature does not let the entering of line breaks.

Any time you are sending out the form, the data put in by the user is available on the web server side by means of the

"name"

attribute, applied to identify each related information included in the request specifications.

To gain access to the info entered when we handle the form having some variety of script, to verify the content as an example, it is important to have the materials of the value property of the object in the DOM. (read this)

Security password

<Input type="password" name="pswd">

Bootstrap Input Class that gets the

type="password"

attribute is very much the same to the text type, except that it does not show exactly the text message inserted at the hand of the site visitor, though prefer a series of signs "*" otherwise yet another being dependent on the browser and functional system .
