$.ajax({&nbsp; &nbsp; type:"GET",&nbsp; &nbsp; url:"json/index.json",&nbsp; &nbsp; async:true,&nbsp; &nbsp; success: function (data) {&nbsp; &nbsp; &nbsp; &nbsp; let list = '';&nbsp; &nbsp; &nbsp; &nbsp; for (let i in data.data) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //子节点循环&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; let pic = '';&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; let line = data.data[i].picurl&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; for (let x in line) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; pic += `<div class="image"><img src="${data.data[i].picurl[x].pic}"></div>`&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; list += `<li>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <a href="javascript:">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="list_top flex">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="head-time f1">${data.data[i].time}</div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="head-true_false f1">${data.data[i].state}</div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="content_img">${pic}</div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="footer">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="number_monet">共${data.data[i].numbers}件商品，实付<span class="money">￥${data.data[i].money}</span></div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="fd">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <object><a href="javascript:" class="btn">${data.data[i].btn}</a></object>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </a>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </li>`;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; $('.list_ul').prepend(list)});

Answer 2

应该把第二个循环放到第一个循环的里面。for (let i in data.data) {&nbsp; y = i;&nbsp; ...&nbsp; let line = ...&nbsp; for (let x in line)}

Answer 3

这么简单的逻辑错误！
