返回前一个浏览的页面 back()方法,加载 history 列表中的前一个 URL. 语法: window.history.back(); 比如,返回前一个浏览的页面,代码如下: window.history.back(); 注意:等同于点击浏览器的倒退按钮. back()相当于go(-1),代码如下: window.history.go(-1); 任务 补充右边代码编辑器第9行,完善GoBack()函数,实现返回前一个页面功能. 注意:本编辑器有局限性,可以把代码拷贝到本机上练习,或者在本节…

返回浏览历史中的其他页面 go()方法,根据当前所处的页面,加载 history 列表中的某个具体的页面. 语法: window.history.go(number); 参数: 浏览器中,返回当前页面之前浏览过的第二个历史页面,代码如下: window.history.go(-2); 注意:和在浏览器中单击两次后退按钮操作一样. 同理,返回当前页面之后浏览过的第三个历史页面,代码如下: window.history.go(3); 任务 补充右边代码编辑器第9行和第13行,使用go()方法,完善G…
