Question

您好我有以下代码：

const array1 = "Accessories:Bracket,Accessories:Clamp,Actuator:Accessories,Actuator:Accessories:Bracket,Actuator:Accessories:Clamp,Actuator:Clevis".split(
  ","
);
const array2 = "24092859,24092784,24094450,24094451,24110219,24092811".split(
  ","
);

const output = array1.reduce(
  (topLevelNodes, path, i) => {
    let nodes = topLevelNodes;
    let mtdId = array2[i];
    path.split(":").forEach(text => {
      let node = nodes.filter(child => child.text === text)[0];
      if (node) {
        node.mtdId += "," + mtdId;
      } else {
        nodes.push((node = { text, children: [], mtdId }));
      }
      nodes = node.children;
    });
    return topLevelNodes;
  },
  []
);

console.log(output);

现在我想添加显示左侧的代码 h1 id =＆＃34;教父＆＃34;在值1，
h1 id =＆＃34; shawshank＆＃34;价值2 或者可能是第三个值3

我怎样才能做到这一点？提前致谢

</div>

</body>
<script>
function test() {
            var val= document.getElementById('1').value;

    if (val == '1') {
        document.getElementById('godfather').innerHTML = 'God Father';

    }
    if (val == '2') {
        document.getElementById('godfather').innerHTML = 'shawshank';

    }
    if (val == '3') {
    document.getElementById('godfather').innerHTML = 'Anything Else';
    }
    else{

    }
    }
