Bootstrap Input Text

Overview

Most of the elements we apply in documents to capture site visitor info are from the

<input>

tag.

You can without trouble add to form directions simply by adding words, switches, or button groups on each side of textual

<input>

-s.

The different kinds of Bootstrap Input Validation are established with value of their kind attribute.

Next, we'll detail the approved kinds with regard to this kind of tag.

Text

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

Perhaps the absolute most prevalent form of input, which has the attribute

type ="text"

, is used each time we want the user to write a elementary textual details, because this kind of component does not support the entering of line breaks.

When ever sending out the form, the info inserted by site visitor is available on the server side by means of the

"name"

attribute, chosen to recognize every related information provided in the request specifications.

To access the details typed when we manage the form together with some kind of script, to verify the information for example, it is important to receive the materials of the value property of the object in the DOM. ( learn more)

Password

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

Bootstrap Input Group that is given the

type="password"

attribute is much the same to the text type, besides that it does not present exactly the text inserted at the hand of the site visitor, on the other hand prefer a set of signs "*" or yet another basing on the web browser and working system .

Standard Bootstrap Input Text 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>

  <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 related form sizing classes to the

.input-group

in itself and details within will immediately resize-- no necessity for restating the form regulation scale classes on each and every 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">

  <span class="input-group-addon" id="sizing-addon2">@</span>

</div>

Set any type of checkbox or radio possibility inside of an input group’s addon as an alternative to of text.

true

, you can establish any value for the checkbox.

      <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>

When we would like the site visitor to select only one of a series of options, we can possibly put into action input features of the radio type.

Just one particular can surely be picked when there is higher than a single feature of this particular option along with the same value inside the name attribute.

<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>
