Question

我为此苦苦挣扎，它看起来很简单，但我做不到，我有javascript循环，我想将表格内的信息打印出来对我来说很好，但是我希望每行的最后一个单元格应为href向其添加ID，以便将href更改为最后一个单元格的第一行将被编辑。将编辑下一行的下一个单元格，这些由数据创建的数字来自循环中的数据，请检查代码，我尝试用单引号或双引号，但它不起作用，它将href内部的内容视为字符串，而不是函数或某些必须值

var config = {
  apiKey: "my_secret_key",
  authDomain: "xyz.firebaseapp.com",
  databaseURL: "https://xyz.firebaseio.com",
  projectId: "xyz",
  storageBucket: "xyz.appspot.com",
  messagingSenderId: "0000000000000"

};

firebase.initializeApp(config);
var db = firebase.firestore();

db.collection("users").onSnapshot(function(querySnapshot) {

  querySnapshot.forEach(function(doc) {
    // doc.data() is never undefined for query doc snapshots
    var_data = doc.data().firt_name;
    var_last = doc.data().last_name;
    document.getElementById("table").innerHTML += "<tr><td>" + doc.data().first_name + " </td>" +
      "<td>" + doc.data().last_name + "</td>" + "<td>" + doc.data().active +
      "<td>" + "<td><a href='x.php?id='doc.data().first_name >Edit</a></tr>";

  });

});

您可以这样尝试：

var config = {
  apiKey: "my_secret_key",
  authDomain: "xyz.firebaseapp.com",
  databaseURL: "https://xyz.firebaseio.com",
  projectId: "xyz",
  storageBucket: "xyz.appspot.com",
  messagingSenderId: "0000000000000"

};

firebase.initializeApp(config);
var db = firebase.firestore();

db.collection("users").onSnapshot(function(querySnapshot) {

  querySnapshot.forEach(function(doc) {
    // doc.data() is never undefined for query doc snapshots
    var_data = doc.data().firt_name;
    var_last = doc.data().last_name;
    document.getElementById("table").innerHTML += "<tr><td>" + doc.data().first_name + " </td>" +
      "<td>" + doc.data().last_name + "</td>" + "<td>" + doc.data().active +
      "<td>" + "<td><a href='x.php?id=" + doc.data().first_name + "'>Edit</a></tr>";

  });

});

           <table id="table" >
                <th>name</th>
                <th>last</th>
                <th>active</th>
                <th>id</th>
                <tr>
                    
                </tr>
            </table>

通过Java脚本创建href并添加var
