为什么我不能让这个工作代码的jsFiddle？

Question

我的代码在我的电脑上，我的所有浏览器（包括IE）都能正常工作，但我无法设法使它在jsFiddle上工作。

的问题似乎是：

window.onload=function(){ 
     document.body.innerHTML+=brd+log; 
    } 

但我既没有在window.onload尝试。我完全不知所云，我开始失去所有希望

CSS（可选）：

 *{margin:0;padding:0;} 
     #brd{margin:15px auto;} 
     #brd,#brd td,#log{border:1px solid #000;} 
     #brd td{height:47px;width:45px;text-align:center;font-size:30px;} 
     #brd span{font-size:12px;} 
     #log{margin:15px auto;padding:20px;width:385px;max-height:150px;overflow:auto;background:#F0F0F0;color:#000;} 

的JavaScript：

Answer 1

它工作正常，看here

PS：您应该选择no wrap (head)选项。

Answer 2

如果您查看jsFiddle的源代码，您将看到所有javascript已包装在window.onload函数中。

外的window.onload函数被调用后，内部功能将无法执行，因为该文件已加载：

window.onload=function(){ 
    window.onload=function(){ 
     // this code will never get executed. 
    } 
}
