按照w3school的教程写的例子，出现如下提示Uncaught TypeError: Cannot set property 'innerHTML' of nullat 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？？？？？

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]
