看了这里说的：[https://www.cnblogs.com/LLLLLLL/p/5345627.html][https_www.cnblogs.com_LLLLLLL_p_5345627.html]

> 起因：升级了IE11之后部分页面刷新时会出现"SCRIPT5007: 缺少对象 "的报错，查看之后发现是Uploadify目前不支持IE11。

每次打开页面就报错，IE11上传后不能继续执行其他js，除了IE11都可以。

以下操作并没有解决我的问题：

> 在页面头部添加<meta http-equiv="X-UA-Compatible" content="IE=edge" >
> 
> 通过在meta中设置X-UA-Compatible的值，指定IE8/9及以后的版本都会以最高版本IE来渲染页面。

我参考的修改源码方法：

//原来的代码是
    SWFUpload.prototype.cleanUp = function(f) {
        try {
            if (this.movieElement && typeof(f.CallFunction) === "unknown") {
                this.debug("Removing Flash functions hooks (this should only run in IE and should prevent memory leaks)");
                for (var h in f) {
                    try {
                        if (typeof(f[h]) === "function") {
                            f[h] = null;
                        }
                    } catch(e) {}
                }
            }
        } catch(g) {}
        window.__flash__removeCallback = function(c, b) {
            try {
                if (c) {
                    c[b] = null;
                }
            } catch(a) {}
        };
    };

修改后

//新代码
    SWFUpload.prototype.cleanUp = function(f) {
        try {
            if (this.movieElement && typeof(f.CallFunction) === "unknown") {
                this.debug("Removing Flash functions hooks (this should only run in IE and should prevent memory leaks)");
                for (var h in f) {
                    try {
                        if (typeof(f[h]) === "function" && h[0] >= 'A' && h[0] <= 'Z') {
                            f[h] = null;
                        }
                    } catch(e) {
    
    }
                }
            }
        } catch(g) {
    
    }
    
        window.__flash__removeCallback = function(c, b) {
            try {
                if (c) {
                    c[b] = null;
                }
            } catch(a) {}
        };
    };

改了源码终于解决了。
