Using an if statement to check if a div is empty

by

You can use .is().

if( $('#leftmenu').is(':empty') ) {
    // ...

Or you could just test the length property to see if one was found.

if( $('#leftmenu:empty').length ) {
    // ...

Keep in mind that empty means no white space either. If there’s a chance that there will be white space, then you can use $.trim() and check for the length of the content.

if( !$.trim( $('#leftmenu').html() ).length ) {
    // ...
