JS table sorted by a column

The essence is that the object is sorted by an attribute

This takes the form of JSON data returned in the first order

/* Sort */
function Getsortfun (order, SortBy) {
var Ordalpah = (Order = = "ASC")? ">": "<";
var sortfun = new Function ("A", "B", "return a." + SortBy + ordalpah + "B." + SortBy + "?) 1:-1 ");
return sortfun;
}

/*

Data returned back to the background

Table is the table that is currently being sorted

SortBy What fields to sort by

Renderfun is a function of rendering tables

*/

Descending
function Sortdown (data,table,sortby,renderfun) {
Data.sort (getsortfun (' desc ', sortby));
Renderfun (Table,data);
};
Ascending
function Sortup (data,table,sortby,renderfun) {
Data.sort (Getsortfun (' ASC ', SortBy));
Renderfun (Table,data);
};
