@click=“this.$router.go(-1)”

This is a Vue.js directive used to navigate back to the previous page in the browser history using the Vue Router. The `click` attribute specifies that the directive should trigger when the element is clicked, and the value `"this.$router.go(-1)"` is the JavaScript code that tells the router to go back one step in the history. This directive can be used on any HTML element that can be clicked, such as a button or a link.

this.$router.go的实现原理

this.$router.go的实现原理是通过改变浏览器的历史记录来实现路由跳转。当调用this.$router.go(n)时，n表示要向前或向后跳转的步数。如果n为正数，则向前跳转n步；如果n为负数，则向后跳转n步。具体实现原理如下：
1. 当调用this.$router.go(n)时，Vue Router会检查当前路由的历史记录长度。
2. 如果n大于0并且小于或等于历史记录长度，则通过window.history.go(n)来执行向前跳转n步。
3. 如果n小于0并且的绝对值小于或等于历史记录长度，则通过window.history.go(n)来执行向后跳转n步。
4. 如果n超过历史记录长度，则通过window.location.reload()来刷新页面，达到跳转到指定页面的效果。
总之，this.$router.go的实现原理是通过改变浏览器的历史记录来实现路由跳转。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

this.$router.go如何跳过锚点

this.$router.go方法用于进行页面的前进或后退操作。它接受一个参数，表示跳转的步数。当参数为正数时，表示向前跳转；当参数为负数时，表示返回（相当于back）。所以如果要跳过锚点，可以通过设置跳转步数为负数来实现。例如，使用this.$router.go(-2)可以跳过两个页面，包括锚点页面，返回到前两个页面。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
