Question

我希望获取<div>中的文本或DOM属性的值，值为保卫科，但我总是得到undefined或JS错误。

我是JS的新手。我正在尝试一些方法来获取div的文本，但我失败了。我需要帮助。

这个HTML片段是一个组织结构图，我现在遍历它以获得它所代表的结构并将结果值连接成一个json对象，但我不熟悉JS DOM操作，这让我整天困扰

＆＃13;

function loop($chart) {
        // var that = this;
        //$chart是一个DOM
        var $tr = $chart.find('tr:first');
        //找到根结点 获取id id为1 拼接json
        // console.log($tr);
        console.log($tr.find('.node:first').innerText);
        var subObj = { 'id': $tr.find('.node')[0].id ,'name':$tr.find('.node')[0].value};
        //找到tr中的最后一个 记录子节点的tr 然后遍历
        $tr.siblings(':last').children().each(
          function () {
            //如果subObj没有子节点 则创建一个数组装子节点
            if (!subObj.subordinate) {
               subObj.subordinate = [];
              }
              //往数组中push东西
            subObj.subordinate.push(loop($(this)));
          });
        return subObj;
      }

我试过它有效：

function myFunction() {
   var x = document.getElementById("1512554614742741").getAttributeNode("value").value;
    //here you have 保卫科  in x variable but it doesn't show anywhere on the page
    //you choose what you want to do  with it for example show it in the html page
}

如何获取此div文本或此DOM的值？
