Javascript、getElementById 和样式不起作用 : Uncaught TypeError: Cannot read property 'style' of null

Question

我这里有这段代码:

document.getElementById('success').style.display("block");
document.getElementById('success').text("aaaa"); 

我收到这个错误，为什么？

Uncaught TypeError: Cannot read property 'style' of null 

<span id="success" style="color:#FFF; display:none;"></span>

我将我的代码移到了页面底部，现在我收到了这个新错误

Uncaught TypeError: Property 'display' of object #<CSSStyleDeclaration> is not a function

Answer 1

应该是:

var elSuccess = document.getElementById('success');
elSuccess.style.display = 'block';
elSuccess.innerText = 'aaa';
