Employing jQuery's CSS method

Question

Employing jQuery's CSS method

As someone who is new to coding, I decided to create a basic color game using jQuery. The idea is simple - there are 4 options, you click the correct one, and an alert appears. I stored the answer along with some dummy colors in an array called "colors[]" and used that array to set the CSS for each color box.


var dummy = '#ccc';
var answer = '#ff9900';

var colors = [dummy,answer,dummy,dummy];

for (var i = 1; i <= 4; i++) {
  $('#colorBox'+i).css('background', ''+colors[i-1]+'');
}

$('#colorBox'+i).click(function() {
  if ($(this).css('background', ''+colors[answer]+'') == true) {
    alert("Congratulations!");
  }

However, I'm struggling to properly define the answer for the click function to work correctly. Any help would be greatly appreciated. Thank you.

Answer №1

After reviewing your code, I have identified a few key issues that need to be resolved.

Ensure to use the getter method for css() in the conditional statement and compare it directly to the answer string, as referencing colors[answer] is not valid.
Avoid repeatedly appending empty strings, as this can impact performance unnecessarily.
Move the click handler code inside the loop so that it properly interacts with the i variable.

However, the major flaw in your logic lies in assuming that all browsers return CSS colors in the same format, whether hexadecimal or RGB. This inconsistency could lead to errors in color comparison.

A more effective solution would involve applying classes to elements for easier identification of the correct answer. By grouping common elements under single classes instead of using incremental id attributes, you can streamline your code. Consider the following revised approach:

var classes = ['d', 'a', 'd', 'd'];
var $container = $('.container');

var html = '';
for (var i = 0; i < classes.length; i++) {
html += '<div class="colorbox ' + classes[i] + '"></div>';
}
$container.append(html).on('click', '.colorbox', function() {
    if ($(this).hasClass('a')) {
        alert("Congratulations!");
    }
});

.colorbox {
    width: 50px;
    height: 50px;
    border: 1px solid #000;
}
.colorbox.a {
    background-color: #ee00aa;
}
.colorbox.d {
    background-color: #aaa;
}
