I have a div that I want to be "activated" on a click but only the first time, only when it doesn't exist yet ; I don't want to use display:none
by default because when coming back to the page afterwards I would have to click again to make it appear.
To sum up, is there any way to "activate" a div instead of using show/hide? ( createElement
and append
would make a new one on each click...)
You can use appendTo()
for that. If you give that div
an unique ID, you can check if it exists
$('button').on('click', function() { if( $('#uniqueID').length == 0 ) { $('<div id="uniqueID">This is a div</div>').appendTo('body'); } });
div { border: 1px solid blue; margin: 1em; padding: 1em; }
