GetElementById不是函数？

Question

运行此脚本时,我收到一条错误消息,即document.GetElementById不是函数？- 您可以在以下网址查看该网站:http://www.fritidsjobbere.dk:

//Show random div with Javascript
antal = 6;
var randomnumber=Math.floor(Math.random()*antal);
if(randomnumber == "0") {
randomnumber = 1;
}
//alert(randomnumber);
document.getElementsById("partner-ad"+randomnumber).style.display = 'block'; 

Answer 1

getElementsById - > getElementById
