将 Font Awesome 图标设置为光标 - 这可能吗?

2022-01-17 00:00:00 javascript html css html5-canvas font-awesome

Font Awesome 有一个非常好的图标集合，可用于 Web 项目.我想使用其中一个图标作为光标(自定义光标).

Font Awesome has a very good collection of icons to be used in web projects. I want to use one of those icons as cursor (custom cursor).

据我了解，自定义光标需要一个图片网址，但我无法找到 Font Awesome 图标的图片网址.

In my understanding, Custom Cursors need an image url, but I am unable to find the image urls for Font Awesome icons.

推荐答案

知道了！

  1. 创建画布
  2. 在上面画上fa图标
  3. 改成base-64的图片url
  4. 在光标css样式上应用图片

$(function() {
    var canvas = document.createElement("canvas");
    canvas.width = 24;
    canvas.height = 24;
    //document.body.appendChild(canvas);
    var ctx = canvas.getContext("2d");
    ctx.fillStyle = "#000000";
    ctx.font = "24px FontAwesome";
    ctx.textAlign = "center";
    ctx.textBaseline = "middle";
    ctx.fillText("uf002", 12, 12);
    var dataURL = canvas.toDataURL('image/png')
    $('body').css('cursor', 'url('+dataURL+'), auto');
});

body {
    position: fixed;
    left: 0;
    right: 0;
    top: 0;
    bottom: 0;
}
