InputSetter

InputSetter is a plugin that allows for updating DOM out of the scope of droplab when a list item is clicked.

Usage

Add the InputSetter object to the plugins array of a DropLab.prototype.init or DropLab.prototype.addHook call.

• InputSetter requires a config value for input and valueAttribute.
• input should be the DOM element that you want to manipulate.
• valueAttribute should be a string that is the name of an attribute on your list items that is used to get the value to update the input element with.

You can also set the InputSetter config to an array of objects, which will allow you to update multiple elements.

<input id="input" value="">
<div id="div" data-selected-id=""></div>

<input href="#" id="trigger" data-dropdown-trigger="#list">
<ul id="list" data-dropdown data-dynamic>
  <li><a href="#" data-id="{{id}}">{{text}}</a></li>
<ul>

  const droplab = new DropLab();

  const trigger = document.getElementById('trigger');
  const list = document.getElementById('list');

  const input = document.getElementById('input');
  const div = document.getElementById('div');

  droplab.init(trigger, list, [InputSetter], {
    InputSetter: [{
      input: input,
      valueAttribute: 'data-id',
    } {
      input: div,
      valueAttribute: 'data-id',
      inputAttribute: 'data-selected-id',
    }],
  });

  droplab.addData('trigger', [{
    id: 0,
    text: 'Jacob',
  }, {
    id: 1,
    text: 'Jeff',
  }]);

Above, if the second list item was clicked, it would update the #input element to have a value of 1, it would also update the #div element's data-selected-id to 1.

Optionally you can set inputAttribute to a string that is the name of an attribute on your input element that you want to update. If you do not provide an inputAttribute, InputSetter will update the value of the input element if it is an INPUT element, or the textContent of the input element if it is not an INPUT element.
