JavaScript - 随机获取数组元素

var myArray = ['one', 'two', 'three', 'four', 'five'];
var rand = Math.floor(Math.random() * myArray.length);
var rValue = myArray[rand];
console.log(rValue)

解析gif

SuperGif解析的帧是空的。不知道什么原因，反正获取不到。

line:3610:

'table.ke-zeroborder td {border:1px dotted #AAA;}',
替换成,防止td内输入数字英文不会换行。
'table.ke-zeroborder td {border:1px dotted #AAA;word-wrap: break-word;word-break: break-all;}',

line:6865

imgPath = self.pluginsPath + name + '/images/',
下面加(定义删除图片的api)：
delImgApi = K.undef(self.delImgApi, 'delurl'),
//配置时记得自定义参数：delImgApi:'https://xxxxxxx'

line:6884

'<div style="padding:10px 20px;">',
下面加
'<style type="text/css">',
            '.relative{position:relative;}',
            '.operate-box{',
            '  position:absolute;top:-100px;left:0px;',

            '</style>',

line:6937

el.click(function(e) {
    clickFn.call(this, fileUrl, data.filename);
});
改成：
$(el).find(".icon-add").click(function(e) {
    clickFn.call(this, fileUrl, data.filename);
});

line:7009

.mouseover(function(e) {
    K(this).addClass('ke-on');
})
改成
.mouseout(function(e) {
    K(this).removeClass('ke-on');
    //删除图片功能：鼠标移出，让操作框向下滑出
    $(K(this)).find(".operate-box").css({"top":"-100px"});
});

line:7018

var img = K('<img src="' + iconUrl + '" width="80" height="80" alt="' + data.filename + '" />');
                if (!data.is_dir || data.has_file) {
                    photoDiv.css('cursor', 'pointer');
                    bindTitle(photoDiv, data);
                    bindEvent(photoDiv, result, data, createView);
                } else {
                    photoDiv.attr('title', lang.emptyFolder);
                }
                photoDiv.append(img);
加个属性data-id
并且在img绑定事件之前 增加删除按钮 
替换成
var img = K('<img src="' + iconUrl + '"  data-id="' + data.id + '" width="80" height="80" alt="' + data.filename + '" />');

                photoDiv.append(img);
                //添加删除图片功能
                var bgHtml = [
                    '<div class="operate-box">',
                    '  <div class="black_overlay"></div>',
                    '  <div class="operate">',
                    '      <div class="left"><img src="'+imgPath+'add_24.png" alt="" class="icon-add"/></div>',
                    '      <div class="right"><img src="'+imgPath+'delete_24.png" alt="" class="icon-delete"/></div>',
                    '  </div>',
                    '</div>'
                ].join(" ");
                photoDiv.append(bgHtml);
                if (!data.is_dir || data.has_file) {
                    photoDiv.css('cursor', 'pointer');
                    bindTitle(photoDiv, data);
                    bindEvent(photoDiv, result, data, createView);
                } else {
                    photoDiv.attr('title', lang.emptyFolder);
                }
                $(photoDiv).find(".icon-delete").click(function(event){
                    if(!confirm("确认删除该图片吗？")) return false;
                    var parentDiv =  $(this).parents(".ke-item");
                    var id_ = $(this).parents(".ke-photo").find("img:first").attr("data-id");
                    //发送删除图片请求
                    $.post(delImgApi,{imgId: id_},function(json){
                        if(json.error===0) {
                            parentDiv.remove();
                        } else {
                            alert(json.message);
                        }
                    },"json");
                });

最后补充两个icon在路径：
\kindeditor\plugins\filemanager\images
自己不喜欢可以替换
