[javascript] 二維陣列的排序
陣列格式 var a = [ {name:'hdj', filename:20140930174726.jpg}, {name:'yim', filename:1_title.jpg}, {name:'hdq', filename:20150930174726.jpg}, {name:'rrr', filename:3_title.jpg}, {name:'ddd', filename:2_title.jpg}, ]; 希望根據 filename 來進行排序，可以使用底下的 function function listSortBy ( arr , field , order ){ var refer = [], newrefer = [], comp_arr =[], result =[]; var order = order == ' asc' ? ' asc ' : 'desc ' , index ; for ( i = 0 ; i < arr . length ; i ++){ // 1_title.jpg 20140930174726.jpg var delExt = arr [ i ][ field ]. split ( "." ); // 1_title 20140930174726 var name = delExt [ 0 ]. split ( "_" ); if ( typeof ( name [ 1 ]) == 'undefined' ) { refer [ delExt [ 0 ]] = i ; comp_arr [ i ] = delExt [ 0 ]; } else { refe
