layui 魔改：富文本编辑器添加上传视频功能

甲方又整新需求了：富文本编辑器需要可以传视频。

layui本身的富文本编辑器没有传视频的功能，所以，又到了咱们魔改的时候了。

友情提醒，富文本编辑器 layedit 只有layui的V1版有，V2版没了，也是很神秘。

因为上次咱们加了上传加了进度条，所以这回的上传也是有进度条的，只不过在富文本编辑区的外面。

上代码。

需要用编辑器的某个HTML的JS域：

var layeditIndex = layedit.build('intro', {
    height: 600,
    uploadImage: {
        url: 'xxx'
    },
    uploadVideo: {
        url: 'xxx',
        exts: 'mp4',
        xhr:xhrOnProgress,
        progress:function(value){//上传进度回调 value进度值
            element.progress('demo', value+'%')//设置页面进度条
            console.log(value)
        },
        before: function(obj){
            element.progress('demo', '0%')
            $("#uploadLoadingDiv").show()
        }
    }
});

var xhrOnProgress=function(fun) {
    console.log("xhrOnProgress")
    xhrOnProgress.onprogress = fun; //绑定监听
    //使用闭包实现监听绑
    return function() {
        //通过$.ajaxSettings.xhr();获得XMLHttpRequest对象
        var xhr = $.ajaxSettings.xhr();
        //判断监听函数是否为函数
        if (typeof xhrOnProgress.onprogress !== 'function')
            return xhr;
        //如果有监听函数并且xhr对象支持绑定时就把监听函数绑定上去
        if (xhrOnProgress.onprogress && xhr.upload) {
            xhr.upload.onprogress = xhrOnProgress.onprogress;
        }
        return xhr;
    }
}

layedit.js:

...
      var e = layui.$,
        i = layui.layer,
        a = layui.form,
        l = (layui.hint(), layui.device()),
        n = "layedit",
        o = "layui-show",
        r = "layui-disabled",
        c = function() {
            var t = this;
            t.index = 0, t.config = {
                tool: ["strong", "italic", "underline", "del", "|", "left", "center", "right", "|", "link", "unlink", "face", "image", "video"],
                hideTool: [],
                height: 280
            }
        };
...
image:function(){...}
                    video: function(a) {
                        var n = this;
                        layui.use("upload", function(o) {
                            var r = l.uploadVideo || {};                            
                            o.render({
                                url: r.url,
