Bootstrap Input Box

Introduction

A lot of the components we put into action in data sheets to catch site visitor information are coming from the

<input>

tag.

You may easily extend form dominions via incorporating text, buttons, or tab groups on each part of textual

<input>

-s.

The different types of Bootstrap Input Button are established by value of their option attribute.

Next, we'll describe the accepted options with regard to this tag.

Text message

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

Undoubtedly the most usual style of input, which owns the attribute

type ="text"

, is made use of anytime we desire the user to give a basic textual information, considering that this kind of element does not let the entry of line breaks.

Whenever you are providing the form, the data entered by user is easily accessible on the server side throughout the

"name"

attribute, utilized to identify every single relevant information contained in the request specifications.

To access the information typed when we manage the form along with some kind of script, to validate the information for example, it is essential to gain the materials of the value property of the object in the DOM. ( useful source)

Code

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

Bootstrap Input Group that accepts the

type="password"

attribute is quite similar to the text type, besides that it does not expose really the words recorded at the hand of the site visitor, though rather a series of symbols "*" or another depending upon the web browser and functional system .

Classic Bootstrap Input Button good example

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

<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">
</div>
<br>
<div class="input-group">
  <input type="text" class="form-control" placeholder="Recipient's username" aria-describedby="basic-addon2">
  <span class="input-group-addon" id="basic-addon2">@example.com</span>
</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">$</span>
  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
  <span class="input-group-addon">.00</span>
</div>
<br>
<div class="input-group">
  <span class="input-group-addon">$</span>
  <span class="input-group-addon">0.00</span>
  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
</div>

Sizes

Bring in the related form sizing classes to the

.input-group

in itself and information inside will instantly resize-- no need for restarting the form regulation sizing classes on each feature.

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

Apply any kind of checkbox or radio feature inside of an input group’s addon as an alternative to of text.

Checkbox button option

Widely used with the value

true

, you can establish any value for the checkbox.

<div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">
        <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 approach

If we require the user to pick a single of a series of opportunities, we are able to put to use input features of the radio style.

As there is more than one element of this one form along with the exact same value inside the name attribute, just one can possibly be picked.

<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>
</div>

  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">

      </span>
      <span class="input-group-addon">$</span>
      <input type="text" class="form-control" aria-label="Text input with checkbox">
    </div>
  </div>

  </div>
</div>

"value"

attribute.
