非正规写法获取不到tr,td 
<!DOCTYPE html>

<html>

    <head>

        <meta charset="UTF-8">

        <title></title>

    </head>

    <body>

    <div id="temp">

        <tr>

            <td>dad</td>

        </tr>

        <tr>

          <td>dad</td>

        </tr>

    </div>

    </body>

    <script>

        var divDom=document.getElementById("temp").innerHTML;

        console.log(divDom);

    </script>

</html>

不管怎么整都获取不到tr,td，想了半天没有想明白，最后在tr上添加table,完整了一下结果，结果出来了，说明想要获取tr,td必须在正规的写法下，例如

<!DOCTYPE html>

<html>

    <head>

        <meta charset="UTF-8">

        <title></title>

    </head>

    <body>

    <div >

        <table id="temp">

            <tr>

                <td>dad</td>

            </tr>

            <tr>

              <td>dad</td>

            </tr>

        </table>

    </div>

    </body>

    <script>

        var divDom=document.getElementById("temp").innerHTML;

        console.log(divDom);

    </script>

</html>

这样就可以获取到tr,td.
