  sColor=sColor.toString(16);   
  if   (sColor.length   <   6)   {   
      var   sTempString   =   "000000".substring(0,6-sColor.length);   
      sColor   =   sTempString.concat(sColor);   
  }   
  alert(sColor);   
  mybody.style.backgroundColor=sColor;   
  }   
  function   getFonts()//Dilog   Helper对象的使用之取得系统支持的字体   
  {   
      var   strFonts="";   
      for(var   i=1;i<dlgHelper.fonts.count;i++)   
      {   
          strFonts=strFonts+dlgHelper.fonts(i)+"|";

              document.execCommand("ForeColor",false,"#ffff00");   
          }   
      }   
  }   
  以下为取得BlockFormats,填充Select（id为myselect）并根据选择不同的BlockFormat改变样式   
  //函数fillselect()和changeformat()   
  //对execCommand的一点说明：Executes   a   command   over   the   given   selection   or   text   range

      disk=fs.GetDrive(drvpath);   
      var   whichtype="";   
      switch(disk.DriveType)   
      {     
    case   0:   
        whichtype="Unknown"   
        break   
    case   1:   
        whichtype="Removable"   
        break

//正则匹配?
?

匹配中文字符的正则表达式： [\u4e00-\u9fa5] 
匹配双字节字符(包括汉字在内)：[^\x00-\xff] 
匹配空行的正则表达式：\n[\s| ]*\r 
匹配HTML标记的正则表达式：/<(.*)>.*<\/\1>|<(.*) \/>/  
匹配首尾空格的正则表达式：(^\s*)|(\s*$)（像vbscript那样的trim函数） 
匹配Email地址的正则表达式：\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)* 
匹配网址URL的正则表达式：http://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)? 
以下是例子： 
利用正则表达式限制网页表单里的文本框输入内容： 
用正则表达式限制只能输入中文：onkeyup="value=value.replace(/[^\u4E00-\u9FA5]/g,&apos;&apos;)" onbeforepaste="clipboardData.setData(&apos;text&apos;,clipboardData.getData(&apos;text&apos;).replace(/[^\u4E00-\u9FA5]/g,&apos;&apos;))" 
1.用正则表达式限制只能输入全角字符： onkeyup="value=value.replace(/[^\uFF00-\uFFFF]/g,&apos;&apos;)" onbeforepaste="clipboardData.setData(&apos;text&apos;,clipboardData.getData(&apos;text&apos;).replace(/[^\uFF00-\uFFFF]/g,&apos;&apos;))" 
2.用正则表达式限制只能输入数字：onkeyup="value=value.replace(/[^\d]/g,&apos;&apos;) "onbeforepaste="clipboardData.setData(&apos;text&apos;,clipboardData.getData(&apos;text&apos;).replace(/[^\d]/g,&apos;&apos;))" 
3.用正则表达式限制只能输入数字和英文：onkeyup="value=value.replace(/[\W]/g,&apos;&apos;) "onbeforepaste="clipboardData.setData(&apos;text&apos;,clipboardData.getData(&apos;text&apos;).replace(/[^\d]/g,&apos;&apos;))"
