html - How to sort a complex list in Javascript? -


i'm stuck question while. have nested list, structure looks 

volume1     chapter4     chapter3         section3-6         section3-1 volume2... ...

what want create sort function sort volume, chapter, , section.

so, result may 

volume1     chapter1         section1-1 ....

so got complex html, here whole html. i'm not sure how swap complex div i've tried element , put them array.

var tosort = document.getelementbyid('volume5015').children; tosort = array.prototype.slice.call(tosort, 0);

i made fiddle you.

in code trimming whitespaces of text don't compared don't have if don't want.

var $items = $("#to-sort").children(); var $resultlist = $("#list2");  sortmarkup($items, $resultlist);  function sortmarkup($elements, $output) {   $elements.sort(function(a, b) {     var contenta = getpuretext(a).trim();     var contentb = getpuretext(b).trim();     var okay = contenta.touppercase().localecompare(contentb.touppercase());      if( $(a).children().length > 0 )         sortmarkup( $(a).children(), $(a) );      if( $(b).children().length > 0 )         sortmarkup( $(b).children(), $(b) );      console.log("sorting ["+contenta+"] , ["+contentb+"] returned "+okay);     return okay;   });    $output.append($elements); }  function getpuretext(elem) {     return $(elem).contents().filter(function() {      return this.nodetype == 3;      })[0].nodevalue; }

also, using output list, thing not required. feel free modify needs!
