javascript - Sorting large number of DOM elements -


i'm pulling large number of nodes sharepoint list , i'll try sort them html table in orderly fashion. way need need split these z:rows 5 different tables. example should self explanatory: https://jsfiddle.net/jse21z9d/1/

$(document).ready(function(){      $('#execb').click(function(){         $('.myul li').each(function(){              var litext = $(this).text().tolowercase();             var newlitext = litext.replace(/[{()}]/g, "");             var textarray = newlitext.split(/[,]/);             console.log(textarray);              $(textarray).each(function(index){                     switch(true){                         case (textarray[index].indexof('pol') != -1):                             $('#poldiv').append(litext+"<br>");                             break;                             case (textarray[index].indexof('uk') != -1)                                     || (textarray[index].indexof('ire') != -1):                                $('#ukdiv').append(litext+"<br>");                             break;                         case (textarray[index].indexof('ger') != -1):                             $('#gerdiv').append(litext+"<br>");                             break;                         case (textarray[index].indexof('san') != -1):                             $('#sandiv').append(litext+"<br>");                             break;                             }              });         });      }); });

so that's got far, , i'm wondering maybe there better way think code wrote might slow entire load lot if talking 1000+ z:rows(li in case) go through?

i modified own code following:
- less appends: iterations generate string instead of multiple appends less actions done on dom.
- less searches: though search id easy search. still better execute once, , append generated string.

i need check if particular url path exists in service worker cache. example, suppose url is: /myserviceworker/service?a=110&b=70 this url exists in cache, there many of them different values of , b. now, suppose want refresh of these urls, how can that? i want know how access key values service worker cache. if know key, plan follows: var url = new url(key); if(url.pathname === "\/myserviceworker/service") refetch key but not sure how cache key , in format is. mean, string or url? cache api has match() method returns promise resolving in response object if match or undefined if no match exists. second parameter object can specify ignoresearch not take account url parameters. the ignoresearch option supported firefox ( chrome status here ). in other hand, retrieve cache entries, can use keys() method.
