Question

I need to add a child selector and child element to a variable, referencing an element.
but i can’t seem to get it working..
I’ve tried;

  var wrapper = $('#wrapper');

  if($(wrapper+' > .box').length > 0)) // unsuccessful

  if(wrapper.add(' > .box').length > 0)) // unsuccessful

  and

  if(wrapper[0]+' > .box'.length > 0)) // unsuccessful

thanks cam

The issue is that you’re confusing the selection with the selector. If you were to have done:

var selector = "#wrapper";
var wrapper = $(selector);

Then you could test it appropriately:

if ( $(selector + " > .box").length )

Note that > is the first-child selector.
