jQuery介绍

jQuery 是一个 JavaScript 函数库,可以在官网下载,其中.min.js是压缩版的,.js是非压缩版的,两者内容一样,只不过压缩版的把大部分换行等去除了,只占据一行或几行。

JS与jQuery页面加载区别

        <title>JS与jQuery加载页面的区别</title>
        <script src="../jquery-1.8.3.min.js"></script>

        <!--JS与jQuery加载页面区别总结:
        1.JS页面加载后面的会覆盖掉前面的
        2.jQuery页面加载不会覆盖,按照代码书写顺序顺次加载
        3.JS页面加载比jQuery慢(JS是在整个页面加载后,才调用window.onload)
        4.jQuery页面加载写法共三种如下
        -->
        <script>

            window.onload=function(){
                alert("JS加载页面1");
            }


            window.onload=function(){
                alert("JS加载页面2");
            }

            $(function(){
                alert("jQuery加载页面1");
            })

            $(document).ready(function(){
                alert("jQuery加载页面2");
            });

            jQuery(document).ready(function(){
                alert("jQuery加载页面3");
            });
