See LICENSE for this software's licensing terms.

AddRemoveTextbox is a jQuery plugin which provides for dynamic creation and removal of input fields, accomplished by clicking add/remove buttons which appear to the right of each field.

Features

• Supports all text-based input types ('text', 'number', etc), plus the 'color' type
• Configurable CSS classes for the 'add' and 'remove' buttons
• Configurable tooltips for the 'add' and 'remove' buttons
• Configurable limit on the number of input fields
• Configurable callbacks for add and remove operations

Initialization

You need to provide a container for all of the input fields. Within that container, you need to provide a container for each set of input field plus buttons. This second container must be the input field's immediate parent.

The plugin will duplicate the input field's immediate parent when creating a new field, so you should't define an ID attribute for the container.

You should provide an id and name attribute for your field(s), and they should be the same value.

      <div id="myTextBoxes">
         <div class="txtBoxRow">
            <input type="text" id="txt0" name="txt0"/>
         </div>
      </div>

      $( "#txt0" ).addRemoveTextbox( {
         addButtonClass      : "addRemoveButton imgAdd",
         addButtonTooltip    : "Add",
         removeButtonClass   : "addRemoveButton imgRemove",
         removeButtonTooltip : "Remove"
      } );

AddRemoveTextbox also understands array notation, so you could use id=txt[0].

You can also initialize AddRemoveTextbox on a large preexisting group of text boxes.

See the included HTML file for more in-depth examples.

Configuration Options

Property	Description	Default Value
addButtonClass	A CSS class to style the 'Add' button. The generated HTML will be a <span>, so it is assumed that you will use CSS to define a background image.	addButton
addButtonTooltip	Hover text for the 'Add' button	null
removeButtonClass	A CSS class to style the 'Remove' button. The generated HTML will be a <span>, so it is assumed that you will use CSS to define background image.	removeButton
removeButtonTooltip	Hover text for the 'Remove' button	null
maxFields	An optional limit on the number of fields which may exist under the applicable ID prefix. If a value is specified, it must be an integer greater than 1.	null (no limit)
contiguous	If true, renumber the id and name attributes upon initialization and when a row is removed. Renumbering is based on DOM order, not id or name values, and starts on the value specified by startingNumber. This setting is disabled by default because it can break applications. Be sure that your application can handle changing IDs and names before using this.	false
startingNumber	This setting is used only when contiguous is set to true.	null
addCallback	A callback function to execute when a field is added. See the demo for more information.	null
removeCallback	A callback function to execute when a field is removed. See the demo for more information.	null
