</html>我已经将javascript文件保存javas.js在我的电脑上.但是,我正在尝试将宽度设置为屏幕宽度的60%(以像素为单位).这不起作用.
我该怎么办呢？请不要说"设置为width:60%".
你有几个语法错误,这里是一个错误的列表:
document.getElementById()+\ 不需要,这是一个格式不正确的文字...但无论如何不需要这里width是一个属性style,只是设置它像我在下面,确保包括"px"在最后.总的来说,它应该只是:
var contentObj = document.getElementById("content");
var widthOfContent = screen.availWidth * 0.6;
contentObj.style.width = widthOfContent + "px";<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
