Usage

Styling form elements

Let's say you wanted to style a dropdown menu with the following html:

<select>
    <option value="MD">Maryland</option>
    <option value="VA" selected>Virginia</option>
    <option value="DC">Washington, DC</option>
</select>

With this library, you can do this:

var dropdown = new Dropdown({
    el: document.getElementsByTagName('select')[0]
});

Which will change your HTML into this:

<div class="dropdown-wrapper">
    <div class="dropdown-container">
        <div class="dropdown-value-container">Virginia</div>
        <div class="dropdown-option-container">
            <div class="dropdown-option" data-value="MD">Maryland</div>
            <div class="dropdown-option dropdown-option-selected" data-value="VA">Virginia</div>
            <div class="dropdown-option" data-value="DC">Washington, DC</div>
        </div>
    </div>
    <select>
        <option value="MD">Maryland</option>
        <option value="VA" selected>Virginia</option>
        <option value="DC">Washington, DC</option>
    </select>
</div>

Then you can style the dropdown using CSS (and just hide the <select> element).

Programmatically change the element's value

Each class comes with a set of utility methods so you can change the elements via JS. Using the example above, you could do the following:

// set the selected value programmatically
dropdown.setValue('DC');

// get the new data value
dropdown.getValue(); // => "DC"

// get the display value
dropdown.getDisplayValue(); // => "Washington, DC"

Listening to change events

You can also listen to events on form elements. Given the following input element...

<input type="text" value="" placeholder="Enter text here" />

You can do the following:

var inputField = new InputField({
    el: document.getElementsByTagName('input')[0],
    onChange: function (el) {
        // user has finished typing into the field!
    },
    onKeyDownChange: function (el) {
        // the user has typed a key into the field!
    }
});
// set the value
inputField.setValue('My text'); // set new value
// get the new value
inputField.getValue(); // => "My text"
