我正在寻找一种将文本颜色更改为 #000 或 #fff 的方法,具体取决于名为“banner”的 div 中背景图像的主要颜色。背景图像是在每个页面上随机选择的,因此我需要能够自动执行此操作。我遇到了JavaScript color contraster,但我很难理解如何正确使用它。我注意到我发布的链接在 javascript 中提供了一个解决方案,我还阅读了 jquery 中可能的解决方案。

我对函数一无所知,所以如果有人能清楚地解释我如何实现这一点,我将函数放置在哪里以及如何“调用它们”(如果这是正确的术语!)使用它,我将非常感激。

谢谢你的帮助。

你可以做这样的事情。(使用Colours.js这个答案

请注意,这仅适用于同一域中的图像以及支持 HTML5 画布的浏览器。

'use strict';

var getAverageRGB = function(imgEl) {
  var rgb = {
    b: 0,
    g: 0,
    r: 0
  };

  var canvas = document.createElement('canvas');
  var context = canvas.getContext && canvas.getContext('2d');
  if (Boolean(context) === false) {
    return rgb;
  }

  var height = imgEl.naturalHeight || imgEl.offsetHeight || imgEl.height;
  var width = imgEl.naturalWidth || imgEl.offsetWidth || imgEl.width;
  canvas.height = height;
  canvas.width = width;
  context.drawImage(imgEl, 0, 0);

  var data;
  try {
    data = context.getImageData(0, 0, width, height).data;
  } catch (e) {
    console.error('security error, img on diff domain');
    return rgb;
  }

  var count = 0;
  var length = data.length;
  // only visit every 5 pixels
  var blockSize = 5;
  var step = (blockSize * 4) - 4;
  for (var i = step; i < length; i += step) {
    count += 1;
    rgb.r += data[i];
    rgb.g += data[i + 1];
    rgb.b += data[i + 2];
  }

  rgb.r = Math.floor(rgb.r / count);
  rgb.g = Math.floor(rgb.g / count);
  rgb.b = Math.floor(rgb.b / count);

  return rgb;
};

var rgb = getAverageRGB(document.getElementById('image'));
var avgComplement = Colors.complement(rgb.r, rgb.b, rgb.g);

var midPoint = Math.floor(maxColors / 2);
