我有一個(gè)簡單的 json 文件，其中包含數(shù)學(xué)運(yùn)算信息。我想將 json 數(shù)據(jù)放入 ul 內(nèi)部，這樣，對(duì)象鍵應(yīng)該是帶有標(biāo)頭類的標(biāo)頭，并且它的值應(yīng)該在每個(gè)標(biāo)頭之后列出。我的腳本文件：{  "Operations":{   " Arithmetic Operations" : ["+", "-", "*", "/"],   "Comparision Operations" : ["Equals","Greater than","Greater than equal to","Less than","Less than equal to"]  }}fetch('./js/data.json')  .then(function (response) {    return response.json();  })  .then(function (data) {    fetchList(data['Operations'])  });fetchList = data => {  Object.entries(data).forEach(([key, values]) => {    let list;    values.forEach(item => {      list = `<li class="list">${ item }</li>`;    });    const li =      `<li class="head">${ key }</li>        ${ list }    `;    console.log(li)    document.querySelector('#operations .lists').innerHTML += li  });}結(jié)果僅顯示每個(gè)值的最后一個(gè)值<li class="head"> Arithmetic Operations</li><li class="list">/</li><li class="head">Comparision Operations</li><li class="list">Less than equal to</li>
