将trList变成数组
获取每一项表情的字符码和分类名 const trList = document.querySelectorAll('table')[0].querySelectorAll('tr') const trArray = Array.from(trList)
const result = [] trArray.map(tr=>{ const first = tr.children[0]; const second = tr.children[1]; if(first.classList.contains('mediumhead')){ console.log(first,'分类') result.push([first.textContent]) }else if(first.classList.contains('rchars')){ if(first.tagName.toLowerCase() === 'th'){ console.log('first','表头') }else{ const last = result[result.length-1] last[1] = last[1]||[] last[1].push(second.textContent) console.log(second,'数据') } } })
得到result 然后序列化 JSON.stringify(result)
得到
