Select an <li> element from div1 and move it to div2 when a button is clicked

Question

Select an <li> element from div1 and move it to div2 when a button is clicked

Even though I have experience with JavaScript, I am struggling to figure out a simple task.

Here is the list of items I need help with:

<div id="left-side">
    <ul>
        <li><div>Item 1</div></li>
        <li><div>Item 2</div></li>
    </ul>
</div>

<input id="addElement" type="button" value="->"/>

<div id="right-side">
</div>

Essentially, what I am looking to do is change the background color of the selected list item on the left when clicked. Then, upon clicking the button, move the selected item to the right div and revert the background color.

Though this seems like it should be straightforward, I am struggling to come up with a solution despite seeing similar implementations online numerous times.

Answer №1

Here is a simple jQuery code snippet that can help achieve the desired functionality:

// Click event to toggle 'active' class on list items
$('#left-side li').click(function() {
     $(this).toggleClass('active');   
});

// Move button click event
$('#addElement').click(function() {
    // Get selected items
    var $items =  $('#left-side li.active');
    // Remove 'active' class
    $items.removeClass('active');
    // Append items to the right side list
    $('#right-side ul').append($items);
});

The code provided above is straightforward and easy to understand.

I have created a demo example to illustrate this: http://jsfiddle.net/NbcS9/

Edit:
If you want to limit selection to only one item at a time on the left list, you can use the following code instead:

// Toggle 'active' class on selected item
$('#left-side li').click(function () {
    // Remove 'active' class from other items
    $('#left-side li').not($(this)).removeClass('active');
    // Toggle 'active' class on the clicked item
    $(this).toggleClass('active');
});

If you're looking to achieve this functionality, using pure JavaScript might be a bit challenging, but with JQuery, it becomes much simpler. By adding click events to two divs, you can easily append the selected text from one to the other. To retrieve the selected data, you can implement a function like the following:

function getSelectedText() {
    var text = "";
    if (window.getSelection) {
        text = window.getSelection().toString();
    } else if (document.selection && document.selection.type != "Control") {
        text = document.selection.createRange().text;
    }
    return text;
}

Additionally, you may want to explore JQuery Draggable(), as it seems like it could be relevant to your desired outcome. http://jqueryui.com/draggable/
