方法：

源代码：

 1 SWFUpload.prototype.cleanUp = function(a) {

 2     try {

 3         if (this.movieElement && typeof(a.CallFunction) === "unknown") {

 4             this.debug("Removing Flash functions hooks (this should only run in IE and should prevent memory leaks)");

 5             for (var c in a) {

 6                 try {

 7                     if (typeof(a[c]) === "function") {

 8                         a[c] = null

 9                     }

10                 } catch(b) {}

11             }

12         }

13     } catch(d) {}

14     window.__flash__removeCallback = function(e, f) {

15         try {

16             if (e) {

17                 e[f] = null

18             }

19         } catch(g) {}

20     }

修正代码：

 1 SWFUpload.prototype.cleanUp = function(f) {

 2     try {

 3         if (this.movieElement && typeof(f.CallFunction) === "unknown") {

 4             this.debug("Removing Flash functions hooks (this should only run in IE and should prevent memory leaks)");

 5             for (var h in f) {

 6                 try {

 7                     if (typeof(f[h]) === "function" && h[0] >= 'A' && h[0] <= 'Z') {

 8                         f[h] = null;

 9                     }

10                 } catch(e) {

11  

12 }

13             }

14         }

15     } catch(g) {

16  

17 }

18  

19     window.__flash__removeCallback = function(c, b) {

20         try {

21             if (c) {

22                 c[b] = null;

23             }

24         } catch(a) {}

25     };
