function renderMarket(list = []) {
    const item1 = list[0];
    const item2 = list[1];
    const jp1Warper = document.querySelector(".rax-view-v2 FloorModule--tmcsModule--27mV5Wq");
    let item1Html = `

    jp1Warper.innerHTML = item1Html + jp1Warper.innerHTML;
}

ajaxPromise({
    url: "http://localhost:9000/api/jp1"
}).then((res) => {
    console.log(res);
    renderMarket(res.data);
})

document.querySelector(".rax-view-v2 FloorModule--tmcsModule--27mV5Wq") 这个 selector 有点问题，FloorModule--tmcsModule--27mV5Wq 没有任何前缀，应该是个 Tag，但显然这不是一个 Tag 的命名，这里应该是 .FloorModule--tmcsModule--27mV5Wq 吧，就是 class？

"${item1.pic}" 的错误要看 res 的结果是啥样，console.log("remote result: ", res.data) 打印出来看看
