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) {}
     };
 };
