javascript - How to use underscore.js sortBy -

i'm trying rearrange multidimensional array json file in underscore template can print out disease highest # of cases lowest # of cases

the problem comes sortby function not sorting arrays.

here illustration array i'm working with

the totalcases array looks like: [163, 134, 98, 118, 2, 167, 152, 102, 49, 4, 0, 0, 0, 1, 0, 0, 1265]

and sortby function is:

<% _.sortby(totalcases , function (num) { %> <%= num %> <% }); %>

it returns 163, 134, 98, 118, 2, 167, 152, 102, 49, 4, 0, 0, 0, 1, 0, 0, 1265

i don't know going wrong how i'm using sortby

you mixing view controller somehow. don't want rearrange array in the underscore template, before presenting it. reread docs sortby, takes callback sort criteria or property name or so, don't want output in there.

<% var sortedcases = _.sortby(totalcases, function(case) { homecoming // sort criteria here, e.g. `case.occurences` }); %><ol><% _.each(sortedcases, function(case) { %> <li><%= case /* … */ %></li> <% } %></ol>
