      var winWidth = 440;

      var winLeft = (screen.width - winWidth) / 2;
      var winTop = (screen.height - winHeight) / 2 - 20;
  
      var str = 'dialogHeight:' + winHeight + 'px;dialogWidth:' + winWidth + 'px;dialogTop:' + winTop + 'px;dialogLeft:' + winLeft + 'px;resizable:yes;center:yes;status:no;'
  
      var rt = window.showModalDialog("Gettext.htm?tmp=" + Math.random(), "输入属性文字", str);

      // 得到图上，所有块对象.
      ss.Select2(5, null, null, null, spFilte);
  
  
      // 遍历每个块.
      for (var i = 0; i < ss.Count; i++) {
