Ext.onReady(function() {
 
  var ProgressBar=new Ext.ProgressBar({
   width:300,
   renderTo:'ProgressBar1'
  });
  var count=0; //滚动条被刷新的次数
  var percentage = 0; //进度百分比
  var progressText = '';
  
  Ext.TaskManager.start({
   run:function(){
    count++;  //计算进度
    if(count > 10){
     ProgressBar.hide();
  }
     percentage = count/10; //生成进度条文字
     progressText = '当前完成进度：' + percentage*100 + "%"; //更新信息提示对话框
     ProgressBar.updateProgress(percentage,progressText,true);
    },
    interval:300,
    repeat:6
  });
});
