How to get the background color code of an element in hex?

Question

How do I get the background color code of an element?

 console.log($(".div").css("background-color"));

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="div" style="background-color: #f5b405"></div>

What I want

#f5b405

Answer 1

Check example link below and click on the div to get the color value in hex.

 var color = ''; $('div').click(function() { var x = $(this).css('backgroundColor'); hexc(x); console.log(color); }) function hexc(colorval) { var parts = colorval.match(/^rgb\\((\\d+),\\s*(\\d+),\\s*(\\d+)\\)$/); delete(parts[0]); for (var i = 1; i <= 3; ++i) { parts[i] = parseInt(parts[i]).toString(16); if (parts[i].length == 1) parts[i] = '0' + parts[i]; } color = '#' + parts.join(''); }

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class='div' style='background-color: #f5b405'>Click me!</div>

There's a bit of a hack for this, since the HTML5 canvas is required to parse color values when certain properties like strokeStyle and fillStyle are set:

var ctx = document.createElement('canvas').getContext('2d');
ctx.strokeStyle = 'rgb(64, 128, 192)';
var hexColor = ctx.strokeStyle;

Answer 3

function getBackgroundColor($dom) {
    var bgColor = "";
    while ($dom[0].tagName.toLowerCase() != "html") {
      bgColor = $dom.css("background-color");
      if (bgColor != "rgba(0, 0, 0, 0)" && bgColor != "transparent") {
        break;
      }
      $dom = $dom.parent();
    }
    return bgColor;
  }

working properly under Chrome and Firefox

Answer 4

实际上，如果某个元素下没有定义background-color ，Chrome 会将其background-color输出为rgba(0, 0, 0, 0) ，而 Firefox 输出为transparent 。

Answer 5

You have the color you just need to convert it into the format you want.

Here's a script that should do the trick: http://www.phpied.com/rgb-color-parser-in-javascript/

Answer 6

My beautiful non-standard solution

HTML

<div style="background-color:#f5b405"></div>

jQuery

$(this).attr("style").replace("background-color:", "");

Result

#f5b405

Answer 7

Adding on @Newred solution. If your style has more than just the background-color you can use this:

$(this).attr('style').split(';').filter(item => item.startsWith('background-color'))[0].split(":")[1]

Answer 8

This Solution utilizes part of what @Newred and @Radu Diță said. But will work in less standard cases.

 $(this).attr('style').split(';').filter(item => item.startsWith('background-color'))[0].split(":")[1].replace(/\s/g, '');

The issue both of them have is that neither check for a space between background-color: and the color.

All of these will match with the above code.

 background-color: #ffffff
 background-color:      #fffff;
 background-color:#fffff;
