When I write code in PHP, if I don’t add a call to any function and press Ctrl + Space, the documentation will appear, showing the names of functions starting with the characters I wrote. And where you can navigate through them (by function names) with the help of arrows - and then their detailed documentation is displayed on the right. How do I get the same with JS? For JS, the names of the functions are shown, but their documentation is not. How to setup? I attach screenshots. PHP: enter image description here Js: enter image description here

  • in principle, that in PHP, that in the JS, quick documentation usually shows information from the comments in the corresponding library file. But, starting from 2018.1, we have improved the documentation for standard javascript api - now the documentation from mdn is shown there ( youtrack.jetbrains.com/issue/WEB-29277 ). Apparently, you have an old version, try to upgrade - lena
  • Just update PHPStorm and everything will work? - user153742
  • I don't know about everything, but the documentation for getElementsByClassName() will definitely look different :) - lena
