JS绑定事件和移除事件的处理方法

addEventListener()与removeEventListener()用于处理指定和删除事件处理程序操作。所有的DOM节点中都包含这两种方法，并且它们都接受3个参数：要处理的事件名、作为事件处理程序的函数和一个布尔值。最有这个布尔值参数是true，表示在捕获阶段调用事件处理程序；如果是false，表示在冒泡阶段调用事件处理程序。

如何去除ecshop标题和网站底部的Powered by ECShop

这个问题困扰大家很久了，感觉Powered by ECShop出现在网站里边不爽，想方设法无法去除。今天在下专门把解决方法贴出来，希望能够方便大家！

注：我们使用ecshop的产品，建议把网站底部的Powered by ECShop留着吧，尊重一下ecshop开发兄弟们的劳动成果嘛！

一.去掉标题栏的’Powered by ECShop’

打开includes/lib_main.php文件；

找到：$page_title = $GLOBALS[‘_CFG’][‘shop_title’] . ‘ - ‘ . ‘Powered by ECShop’;

改为：$page_title = $GLOBALS[‘_CFG’][‘shop_title’];
