4,124 PointsNew color doesn't show up (just a dark grey circle); .on() isn't allowing new colors to be "selected"
Here's my code:
var color = $('.selected').css('background-color');
//When clicking on control list items $('.controls li').on('click', 'li', function() { $(this).siblings().removeClass('selected'); //deselect sibling elements $(this).addClass('selected'); //select clicked elements color = $(this).css('background-color') //cache current color });
//When new color is pressed $('#revealColorSelect').click(function() { changeColor(); $('#colorSelect').toggle(); //Show color select or hide the color select }); //Update the new color span function changeColor() { var r = $('#red').val(); var g = $('#green').val(); var b = $('#blue').val();
$('#newColor').css('background-color', 'rgb(' + r + ',' + g + ',' + b + ')');
} //When color sliders change $('input[type=range]').change(changeColor);
//When add color is pressed //Append the color to the controls ul $('#addNewColor').click(function() { var $newColor = $("<li></li>"); $newColor.css('background-color'), $('#newColor').css('background-color'); $('.controls ul').append($newColor); $newColor.click(); //Select the new color
});
What am I doing wrong?

However, in this case it looks like you have a misplaced parenthesis:
//$newColor.css('background-color'), $('#newColor').css('background-color'); <- misplaced
$newColor.css('background-color', $('#newColor').css('background-color')); // fixed
Also, the base for your delegate click handler should be the outer list, not the list item:
//$('.controls li').on('click', 'li', function() { <- delegate based on item
$('.controls ul').on('click', 'li', function() { // delegate based on list

10,973 PointsIt looks to me like you have a misplaced closing parentheses on the following line:
$newColor.css('background-color'), $('#newColor').css('background-color');
You want to change the value of the $newColor's background-color to the #newColor's background color. So try moving the latter into the parentheses like so:
$newColor.css('background-color', $('#newColor').css('background-color'));

10,973 PointsAs far as .on not allowing new colors to be selected, you need to change the parent selector in your statement. You have .on binded to a click event on the "li" child, but you still have the parent in your code as ".controls li". So the .on method is looking for a "li" child of a ".controls li" parent. In other words, it's looking for a "li" nested within another "li". Sorry if the way I'm explaining this is confusing, as I'm still learning myself. Just change ".controls li" to ".controls". Hope this helps!
