阻止浏览器回退

以在vue中的应用为例：

mounted() {
  history.pushState(null, null, document.URL)
  window.addEventListener('popstate', this.close)
},

destroyed() {
  window.removeEventListener('popstate', this.close)
},

methods: {
  close() {
    this.$emit('close')
  },

  handleBackClick() {
    window.history.go(-1)
    this.close()
  }
}
