起因：ie多次加载uploadify3.2版本这个组件的时候，出现了SCRIPT5007: 缺少对象．

方法：

源代码：

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

修正代码：

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) {}
    };
};
