如何：setAttribute发送5％+ var x％？

Question

我怎样才能让elem.setAttribute("style","border-top-right-radius: 5% 5%;"); 要发送这封elem.setAttribute("style","border-top-right-radius: 5% x%;");

SETT最后5％至变种x的值。

var element1 = document.getElementById("content"), 
style = window.getComputedStyle(element1), 
height = style.getPropertyValue('height'); 

var string1 = height; 
string1 = string1.replace(/\D/g,''); 

var x = string1/100 * 5; 
alert(string1); 
alert(x); 


var elem = document.getElementById("content"); 
elem.setAttribute("style","border-top-right-radius: 5% 5%;");
