Irsf provides the list, sorting, and filtering functions quickly and easily.

Irsf is written in Javascript. irsf implements the list, sorting, and filtering functions (RSF) quickly and easily ).

Irsf consists of three classes.

Irsfsource data source irsffilter filter irsfsorter Sorter

Irsf usage:

Irsf = new irsf (); irsf. draw = function (data) {// display list. The data structure is {property: [{data1}, {data2}]}. * property can be customized, specified by irsfsource .}; // Specify the data source irsf. setsource ({SRC: {items: [{ID: 1121, name: "DFSA" },{ ID: 1122, name: "DFSA"}]}, property: "items"}); // Add the filter irsf. addfilter ("ID", function (ROW) {return row. id = 1121;}); // sets the irsf. setsort (function (a, B) {return. id-b.id;}); // execute and redraw the list will call irsf. draw method irsf. records ();
