json例程编译出现错误
按照w3school的教程写的例子，出现如下提示
Uncaught TypeError: Cannot set property 'innerHTML' of null
at http://localhost:63342/test/.idea/main.js:22:43
完整代码
<!DOCTYPE html>
<html>
<body>
<h2>Create Object from JSON String</h2>
<p id="h1"></p>
<script>
var text = '{"employees":[' +
'{"firstName":"John","lastName":"Doe" },' +
'{"firstName":"Anna","lastName":"Smith" },' +
'{"firstName":"Peter","lastName":"Jones" }]}';
obj = JSON.parse(text);
document.getElementById("h1").innerHTML =
obj.employees[1].firstName + " " + obj.employees[1].lastName;
</script>
</body>
</html>
不知道是不是我的phpstorm设置有问题还是其他原因？？？？？

胡说叔叔
document.getElementById("h1")报错是找不到元素, 是否有id="h1"的元素呢? 字面上理解你可能是写错了, 改为==>document.getElementsByTagName("h1")[0]
