     str = str.replace(/<\/?[^>]*>/g,''); //去除HTML tag
     str = str.replace(/[ | ]*\n/g,'\n'); //Remove trailing blanks
     str = str.replace(/\n[\s| | ]*\r/g,'\n'); //Remove extra blank lines

		if(xTemp == null || xTemp == '') {
			xTemp = "0.00";
		}
	    num = xTemp.toString().replace(/\$|\,/,'');    
	    if(isNaN(num))    
	    num = "0";    
	    sign = (num == (num = Math.abs(num)));    
	    num = Math.floor(num*100+0.50000000001);    
	    cents = num%100;    
	    num = Math.floor(num/100).toString();    
	    if(cents<10)    
	    cents = "0" + cents;    
	    for (var i = 0; i < Math.floor((num.length-(1+i))/3); i++)    
	    num = num.substring(0,num.length-(4*i+3))+','+    
	    num.substring(num.length-(4*i+3));    
	    return (((sign)?'':'-') + num + '.' + cents);    
	}
