如何：setAttribute发送5％+ var x％？

Question

我如何制作elem.setAttribute("style","border-top-right-radius: 5% 5%;"); 发送此elem.setAttribute("style","border-top-right-radius: 5% x%;");

将最后5％设置为var 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%;");

Answer 1

你可以连接字符串：

elem.setAttribute("style","border-top-right-radius: 5% " + x + "%;");

Answer 2

试试这个

var x = string1/100 * 5;
elem.setAttribute('style','border-top-right-radius: 5%'+ x +'%;');
