Vue+Elementui实现多标签页共存的方法

    // 关闭标签
    let ind = state.worktab.list.findIndex(s => s.name === p)
    if (ind > -1) {
     // 清理 keep alive - start
     state.closingPage = state.worktab.list[ind].name
     // 清理 keep alive - end
     state.worktab.list.splice(ind, 1)
    }
    if (p === state.worktab.current.name) {
     // 是当前页，返回上一页
     router.back()
