google chrome - jQuery show function does not work on options in select -

-

i experience following problem jquery , chrome.

i have couple selects , function called on change of select. works ok, after traverse next select element , filter options. [select > option].

on options going filtered call jquery.hide() , if value ok call jquery.show() show elements.

problem is, when call jquery.show(), see change in page source (developer console) on webpage, select still empty.

i tried selected attribute on option, 1 option being added select , showed, one.

everything works ok in firefox, using chrome 41.x. thnks

not sure code looks like, appears work fine in chrome. https://jsfiddle.net/tdetnn4z/

$("#source").on("change", function(){     sourceval = parseint(this.value);     $("#target > option").each(function(){         curr = parseint(this.value);         if(curr%sourceval == 0){             $(this).show();         }         else{             $(this).hide();         }     }) });
