如何在Chrome上批量删除微博

js

let start_at = 0 // 从第0个开始删
let end_at = 10 // 删到第9个
let aa=Array.prototype.slice.apply(document.querySelectorAll('.WB_feed_detail  .W_ficon.ficon_arrow_down.S_ficon')).slice(start_at,end_at)
for(let i=0; i<aa.length; i++){
    setTimeout( () => {
        aa[i].click()
        document.querySelector('[title="删除此条微博"]').click()
        document.querySelector('.layer_mini_opt .W_btn_a').click()
    }, i*1000)
}
