uploadify"ID SWFUpload_0 is already in use..."错误的解决方法

在使用 uploadify时 遇到同时加载的多个页面中包含uploadify组件时就会出现“ID SWFUpload_0 is already in use. The Flash Object Could not be added”的错误，分析代码就会发现，时因为名字累加的问题，解决方法如下

SWFUpload.prototype.initSWFUpload = function (settings) {
try {
    this.customSettings = {};   // A container where developers can place their own settings associated with this instance.
    this.settings = settings;
    this.eventQueue = [];

    //this.movieName = "SWFUpload_" + SWFUpload.movieCount++;
    //名称重复  SWFUpload.movieCount++不能有效累加导致出现重名现象
    //this.movieName = "SWFUpload_" + parseInt(100*Math.random());
    //，从而修改为随机数   modify by 志超 2015.05.21
    var mydate = new Date();
    this.movieName = "SWFUpload_" + mydate.getTime().toString();

//，从而修改为随机数 modify by 志超 2015.09.07

this.movieElement = null;


        // Setup global control tracking
    SWFUpload.instances[this.movieName] = this;

    // Load the settings.  Load the Flash movie.
    this.initSettings();
    this.loadFlash();
    this.displayDebugInfo();
} catch (ex) {
    delete SWFUpload.instances[this.movieName];
    throw ex;
}
};
