Question

我对jQuery和javascript很新，所以也许我错过了一些东西。

我有一个html页面，其中包含最新版jQuery的链接...

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>

但是我尝试在头部或单独的.js文件中执行的任何jQuery代码在我加载页面时都不会运行。不过普通的javascript确实如此。

Firebug承认，当我点击Script或Dom时，jQuery库已经加载了...控制台甚至会毫不费力地接受并运行我的jQuery代码。

这是html ...是的，它是html5，除了Opera和IE之外，它在所有浏览器中运行良好。

            </section>

        </div> 

    </body> 
</html>

有什么我需要知道的东西不在教程中吗？

Answer 1

尝试将代码放入

$(document).ready(function(){    
    // Your code goes here    
});

jQuery可以在Firebug控制台上运行，但不能在页面加载时运行
