javascript - Sort getJson using pure JS - no plugins -
so trying sort external json file. end goal output data table , allow user click on table header , sort data. first trying figure out how sort data. close function below works in 2 out of 3 cases. have use pure js , have following code:
<!doctype html> <html lang="en"> <head> <meta http-equiv="content-type" content="text/html;charset=windows-1252"> </head> <body> <div id="cattable"></div> <script src="http://code.jquery.com/jquery-1.7.1.min.js"></script> <script> function sortjsonarraybyproperty(objarray, prop, direction){ if (arguments.length<2) throw new error("sortjsonarraybyprop requires 2 arguments"); var direct = arguments.length>2 ? arguments[2] : 1; //default ascending if (objarray && objarray.constructor===array){ var proppath = (prop.constructor===array) ? prop : prop.split("."); objarray.sort(function(a,b){ (var p in proppath){ if (a[proppath[p]] && b[proppath[p]]){ = a[proppath[p]]; b = b[proppath[p]]; } } // convert numeric strings integers = a.match(/^\d+$/) ? +a : a; b = b.match(/^\d+$/) ? +b : b; return ( (a < b) ? -1*direct : ((a > b) ? 1*direct : 0) ); }); } } $.getjson('cats.json', function(cats) { sortjsonarraybyproperty(cats, 'cats.coffeepreference'); document.write(cats[0].country); document.write(cats[0].breed); document.write(cats[0].coffeepreference); document.write(cats[1].country); document.write(cats[1].breed); document.write(cats[1].coffeepreference); }); </script> </body> </html> and following external json file cats.json

cats.breed andcats.coffeepreference blank screen when calling function on cats.country. can explain why happening?
latest update
when sort posted larger json-object sort function incurr following error (visible in developer console window): "exception: typeerror: a.match not function".
this caused attempt test numeric contents. .match() method of string object, when a.country or b.country happens empty (=undefined) there is no string object function match() found! if comment out concerning lines
// = a.match(/^\d+$/) ? +a : a; // b = b.match(/^\d+$/) ? +b : b; (or use sort function suggested, see edited version below) problem gone.
update
i had closer @ own sorting routine , found following:
the second argument
propcomplicated: enter composite object name there'cats.coffeepreference'split 2 components. far good, loop on components (in example'cats','coffeepreference') , expect find properties these names incats-objectsa,bpassed sort-callback function. first property'cats'undefined, it's waste of time (and code) looking it. luckily check existance first, nonetheless superfluous.the check numerical data ok, half-hearted. looks strings consisting of numbers , nothing else. so, if variable contained string
' 1'or'2.5'(or stuff'-.1'or'10.30 ') not recognised being "numeric". regexp-based test like/^(?=.*\d)\s*-?\d*\.?\d*\s*?$/.test(a);or alternatively simpler function
!isnan(a)will tell whether
anumeric or not.
i tested sort function and, despite above mentioned shortcomings: it still works!
however, here simplified version of sort:
function catsrt(arr,prop,dir){ dir=dir||1; // default sort direction arr.sort(function(a,b){ var aa=a[prop]||'0',bb=b[prop]||'0'; // '0' in case of "undefined" entries return aa.localecompare(bb)*dir; // use string method localecompare }); } $('button').click(function(){ var prop=$(this).text(),dir=$('input:checked').length==1?-1:1; catsrt(cats,prop,dir); $('#out').html($.map(cats,function(cat){return $.map(cat,function(v,k){ return k+':<span class="'+k+'">'+v+'</span>';}).join(',');}).join('<hr>')); $('.'+prop).css('color',dir>0?'green':'red'); });
