在JS中如何增加一个计算百分比

<script>
function stockColor(now,last){
if(now!=null&&now!=""&&now!=0){
if(now==last) return now;
else if(now>last) return '<font color="red">'+now+'</font>';
else if(now<last) return '<font color="green">'+now+'</font>';
}else return '0.00';
}
var stock=hq_str_sz000688.split(",");
stock[1]=stockColor(stock[1],stock[2]);
stock[2]=stockColor(stock[2],stock[2]);
stock[3]=stockColor(stock[3],stock[2]);
stock[4]=stockColor(stock[4],stock[2]);
stock[5]=stockColor(stock[5],stock[2]);
stock[6]=stockColor(stock[6],stock[2]);
stock[7]=stockColor(stock[7],stock[2]);
stock[30]=stockColor(stock[30],stock[2]);

-----------------------------------------------如何利用上面的增加一个百分比

document.write('<ul class="stock">');
document.write('<li id="stock_code">300029</li>');
document.write('<li id="stock_0">'+stock[0]+'</li>');
document.write('<li id="stock_10"> '+stock[3]+'</li>');
document.write('<li id="stock_1"> '+stock[1]+'</li>');
document.write('<li id="stock_2"> '+stock[2]+'</li>');
document.write('<li id="stock_4"> '+stock[4]+'</li>');
document.write('<li id="stock_5"> '+stock[5]+'</li>');
document.write('<li id="stock_8">'+(stock[8]/10000).toFixed(2)+'万</li>');
document.write('<li id="stock_9">'+(stock[9]/1000000).toFixed(2)+'百万</li>');
document.write('<li id="stock_10">'+stock[30]+'</li>');
document.write(' ---两个数字，如何写出一个百分比？ ');

document.write('</ul>');
//alert('test2');
</script>

Answer 1

functionPercentage(number1,number2){return(Math.round(num/total*10000)/100.00+"%");//小数点后两位百分比}

Answer 2

用img.style.width 试试看
