this full jquery code:

$('.pop-design1').click(function(){             $(".design-preview li:not(.design-preview2).selected").removeclass('selected');             $(".design-list li:not(.design-list2).selected").removeclass('selected');             $(".design-preview2").toggleclass('selected');             $(".design-list2").toggleclass('selected');             $(".overlay").toggle();         });         $('.pop-design2').click(function(){             $(".design-preview li:not(.design-preview3).selected").removeclass('selected');             $(".design-list li:not(.design-list3).selected").removeclass('selected');             $(".design-preview3").toggleclass('selected');             $(".design-list3").toggleclass('selected');             $(".overlay").toggle();         });         $('.pop-design3').click(function(){             $(".design-preview li:not(.design-preview4).selected").removeclass('selected');             $(".design-list li:not(.design-list4).selected").removeclass('selected');             $(".design-preview4").toggleclass('selected');             $(".design-list4").toggleclass('selected');             $(".overlay").toggle();         });         if ($('.design-preview1, .design-preview2, .design-preview3, .design-preview4').not('.selected').length) {     $('.design-preview1').addclass('selected');


want when .design-preview1, .design-preview2, .design-preview3 , .design-preview4 not showing or not selected, want .design-preview1 show default.

what want achieve is: when design-preview1, design-preview2 design-preview 3 , design-preview 4 not have class "selected", add class "selected" "design-preview1"

as requested in question, said want use .not() achieve this. below way can via addselectedclassifnotexists() function.

you can refactor click listeners, run 1 defined function. below modified code question after suggested changes:

var previews = $('.design-preview1, .design-preview2, .design-preview3, .design-preview4');  function addselectedclassifnotexists() {     if (previews.not('.selected').length === previews.length) {         $('.design-preview1').addclass('selected');     } }  function toggleclasses(num) {     $('.design-preview li:not(.design-preview' + num + ').selected').removeclass('selected');     $('.design-list li:not(.design-list' + num + ').selected').removeclass('selected');     $('.design-preview' + num).toggleclass('selected');     $('.design-list' + num).toggleclass('selected');     $('.overlay').toggle(); }  previews.click(function () {     toggleclasses(this.classname.slice(-1));     addselectedclassifnotexists(); });
