Bootstrap Input Class

Overview

Most of the features we work with in applications to catch user data are from the

<input>
tag.

You are able to without trouble extend form limitations via adding in text message, switches, or switch groups on each part of textual

<input>
-s.

The different varieties of Bootstrap Input Text are identified by the value of their type attribute.

Next, we'll uncover the approved kinds regarding this kind of tag.

Text message

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

Possibly some of the most common form of input, which owns the attribute

type ="text"
, is put to use in the event that we would like the user to provide a basic textual details, given that this particular feature does not allow the access of line breaks.

When ever launching the form, the details inserted by site visitor is accessible on the server side throughout the

"name"
attribute, used to identify each data included in the request specifications.

In order to have access to the relevant information typed in if we manage the form with some kind of script, to verify the information as an example, it is necessary to get the elements of the value property of the object in the DOM. ( helpful hints)

Password

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

Bootstrap Input Button that obtains the

type="password"
attribute is much the same to the text type, with the exception that it does not show exactly the words inputed by the user, though prefer a number of symbols "*" otherwise another basing on the browser and working system .

Elementary Bootstrap Input Text example

Place one add-on or button on either side of an input.

 Classic  good example

<div class="input-group">
  <span class="input-group-addon" id="basic-addon1">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-describedby="basic-addon1">

<br>
<div class="input-group">
  <input type="text" class="form-control" placeholder="Recipient's username" aria-describedby="basic-addon2">

</div>
<br>
<label for="basic-url">Your vanity URL</label>
<div class="input-group">
  <span class="input-group-addon" id="basic-addon3">https://example.com/users/</span>
  <input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
</div>
<br>
<div class="input-group">
  <span class="input-group-addon">$</span>
  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">

  <span class="input-group-addon">0.00</span>
  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
</div>

Add in the relative form sizing classes to the

.input-group
itself and components located in will instantly resize-- no need for restarting the form regulation size classes on every element.

 Sizings
<div class="input-group input-group-lg">
  <span class="input-group-addon" id="sizing-addon1">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon1">

  <span class="input-group-addon" id="sizing-addon2">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon2">
</div>

Set any kind of checkbox or radio feature in an input group’s addon in place of of text.

Checkbox button approach

The input element of the checkbox selection is quite regularly applied whenever we have an option that can be noted as yes or no, for example "I accept the terms of the client agreement", or even " Possess the active procedure" in forms Login. ( useful reference)

While commonly utilized with the value

true
, you can certainly identify any value for the checkbox.

        <input type="checkbox" aria-label="Checkbox for following text input">
      </span>
      <input type="text" class="form-control" aria-label="Text input with checkbox">
    </div>
</div>

Radio button option

If we wish the user to choose just one of a set of opportunities, we can easily employ input components of the radio type.

Every time there is much more than one element of this particular style through the same value with the name attribute, just one may be selected.

Radio button option
<div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">
        <input type="radio" aria-label="Radio button for following text input">
      </span>
      <input type="text" class="form-control" aria-label="Text input with radio button">

</div>
