Question

我想为表中的不同tds分配不同的href，以便根据从firestore提取的数据自动生成所述tds。

这是我的oferta.js，我可以从firestore检索数据而不会出现问题，但是我真的不知道如何为td“ titulo”分配不同的href，我尝试使用锚点，但是结果在每个连续的td中都建立相同的URL时，我该如何解决这个问题？，谢谢！！

const ofertaList = document.querySelector('#ofertaLista');


const setupOferta = (data) => {

    let html = '';

    data.forEach(doc => {
      const oferta = doc.data();

      const td =`
        <tr>
          <td><a href="google.com">${oferta.titulo}</a></td>
          <td>${oferta.tipo}</td>
          <td>${oferta.fecha}</td>
          <td>${oferta.areaConocimiento}</td>
          <td>${oferta.cupoLimitado}</td>
        </tr>

      `;
      html += td

    });

    ofertaList.innerHTML = html;
}


db.collection('oferta').get().then((snapshot) =>{

 setupOferta(snapshot.docs)


});

这是最终结果，我想为每个“ Titulo”分配不同的href，但是这样做

<td><a href="google.com">${oferta.titulo}</a></td>

发生这种情况

我想在“ Historia del arte”中放置一个href =“ historia.html”，在“ Matematicas 1”中放置一个href =“ matematicas.html”，这可能吗？如果我不表达自己的意思，对不起清晰

Answer 1

只需将元素的href设置为URL的变量即可：

 let img = new Image();
img.onload = function() {
  context.drawImage(img, 0, 0);
};
img.src =
  "img.png";

Answer 2

<td><a href="${oferta.href}">${oferta.titulo}</a></td>

Answer 3

您可以做到

<td><a href="${oferta.href}">${oferta.titulo}</a></td>

或

<td><a href="http://your-domain.com/${oferta.data_id_or_any_other_field}">${oferta.titulo}</a></td>

添加href以从Firestore自动生成数据表
