How to toggle a child div when i click on a parent div-CodePudding

I'm currently trying to create a dashboard for my website and i'm a pretty begginer with javascript. In this case i'm trying to create a code for toggling a div, i tried to create a function to click in a div with the class "togglebox", and make his child div "togglebox-body" toggle, but it isn't working.

$("main").on('click', '.togglebox', function() {
  const thisBox = $(this).children(".togglebox-body")
  thisBox.toggle()
})
