<input>

tag.

You are able to simply prolong form limitations simply by incorporating words, buttons, or possibly switch groups on each side of textual

<input>

-s.

The separate sorts of Bootstrap Input Validation are identified by value of their type attribute.

Next, we'll show the taken varieties for this particular tag.

Text

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

Undoubtedly easily the most usual style of input, which has the attribute

type ="text"

, is applied in case we want the user to write a simple textual information, considering that this kind of feature does not let the access of line breaks.

When ever sending the form, the data entered by user is available on the server side using the

"name"

attribute, utilized to recognize each info contained in the request parameters.

In order to have access to the data inputed when we manage the form together with some type of script, to confirm the content for example, it is necessary to gain the contents of the value property of the object in the DOM. ( check this out)

Code

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

Bootstrap Input Style that gets the

type="password"

attribute is very similar to the text type, with the exception of that it does not present truly the text message entered by the user, yet instead a set of marks "*" or another being dependent on the browser and operational system .

<form>

Image

type="reset"

takes away the values injected before in the components of a form, helping the user to clean up the form.

<input>

tag of the tab, submit, and reset kinds may possibly be substituted by the

<button>

tag.

In this particular instance, the text of the tab is now indicated as the information of the tag.

It is still necessary to specify the value of the type attribute, although it is a button.

File

<Input type ="file" name ="attachment">

As soon as it is important for the site visitor to provide a file to the program on the web server area, it is needed to apply the file type input.

For the correct delivering of the files, it is usually also important to incorporate the

enctype="multipart/form-data"

attribute in the

<form>

tag.

Hidden

<Input type="hidden" name ="code" value ="abc">

Often times we need to send and receive relevant information that is of no straight usage to the user and because of this should not be presented on the form.

For this function, there is the input of the hidden type, that simply carries a value.
