illustrator插件--常用功能开发--随机填色--js脚本开发--AI插件

  illustrator是矢量编辑软件，画板是绘制处理的重要容器，在印刷方面的一个重要功能就是颜色处理，开发一个随机填充颜色功能，以下功能仅用于学习交流，请勿用于非法用途和商业用途，源代码如下所示：

len = app.activeDocument.selection.length;
gradAlert = 0;
strokes = false;
if (len == 0) {
    alert("Please select one or more objects. Grouped objects will not be affected.");
} else {
    ob = app.activeDocument.selection;
    var line1 = "1. 要随机填充色，输入1-100的数值（数值越大，明度越小） ";
    var line2 = "2.要随机轮廓色，输入1-100的数值并以英文“S”结尾（数值越大，明度越大） ";
    var line3 = "3.要随机不透明度，输入1-100的最小值和最大值，如30,100 ";
    var data = prompt(line1 + line2 + line3, "");
    if (data == null || data.length == 0) {

    } else {
        if (data.indexOf(",") > 0) {
