Answer 3

jack Its used for indicate if #demo have children inserted in it (see the condition in a function). I writed than its possible do without it also because, inside a function, you can test if #demo have children with

if( el.children.length > 0)

Where el is #demo and if it have childs, it mean that current click must REMOVE all while if it have not child it meant ADD all childs

Anyway, i come from Italy

Answer 4

jack i didnt understood the problem.... Can you explain better?

Answer 5

jack Then reviewing:
On clicking #demo you add modul items inside it almost like a list.
After this, of you click on an item what must happen? In your code seem that you want load an iframe (remember iframe and not ifram 😉) by changing on click the src (here also, src and not scr 😉😉) attribute...Then, you want that on clicking #demo (after it have moduls) all moduls would be removed while on modul click, iframe loading would happen?

P.S. Why you used mouseup and mousedown listeners? What they would do?

Answer 9

hey Krow I didnt get what you ment with this last sentence:

to #demo (you can dont use it also but i added it
just for your understanding)
*/

Answer 10

sure I want in this example : when I click on semester it will open the Moduls and now I want If I click on modul that just the click event of modul get triggert and not from the div of semester

Answer 11

there is the div id=demo with the paragraph "1.semester" if you click on it the div will get children with the paragraph "modul 1" "Modul 2" ...

now I want that if I click on the div "1 Semester" that the children get removed but not if I click on modul.
because the modul is inside the dive "1 Semester" it removes the modules than I click on modul

Answer 12

hope that helped you

Answer 13

yes you got it:) I used mouse up and down to know when it's been clicked just on #demo and when also on modul and too add functions in the moment the click ends

Answer 14

I want If I click #demo the Moduls open and click #modul the iframe opens

Answer 15

jack Dont worry.. My main goal here is help other users (and learn with they) 😉😉😉
P.S. If you dont understand something, ask 👍👍

Answer 16

Because hiding it make iframe dont break events handling (it cannot receive events when hided) and allow to make all works
