//函数：regInput(obj, reg, inputStr)
//功能：对于文本框输入数据进行正则表达式匹配
//需配合文件框使用
//例：<input name="D" type="text" id="D"  onKeyPress= "return regInput(this,/^[0-9]{0,4}$/,String.fromCharCode(event.keyCode))" size="2" maxlength="2">

		var srcRange	= obj.createTextRange()
		oSel.setEndPoint("StartToStart", srcRange)
		var str = oSel.text + inputStr + srcRange.text.substr(oSel.text.length)
		return reg.test(str)
