使用JavaScript显示隐藏的div-可在JSFiddle中使用，但不能在实时站点上使用

Question

这段代码在JSFiddle中可以正常工作，但是我无法在实际站点上使用它。 我已经使用网络开发人员检查了JS文件的加载，一切似乎都很好。 我读了一篇有关加载jquery的文章，但我不知道如何或是否需要这样做。 希望有人可以帮助-谢谢。

Answer 1

在document.ready函数内部添加函数，例如：

$(document).ready(function(){
function show(target) {
    document.getElementById(target).style.display = 'block';
}

function hide(target) {
    document.getElementById(target).style.display = 'none';
}
});

还要加载jQuery库：

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
