Hi guys.
I have a problem with jquery (the code is here https://pastebin.com/ieEwvMYW).

I want to make the text written in the textarea appears in the input of the site of the iframe tag. The id of that input is "CreateChatroomInputName" and I put it in a var of jquery ( var myFrame = $("#myframe").contents().find('#CreateChatroomInputName'); ) but it's not considered.

Can you help me to solve this problem?
