Actions | Features | SpreadJS JavaScript Demos

You can add your own key by using the register method to link the keydown event to an action, as shown in the following code: Then press the W, A, S, and D keys to navigate, similar to the up, left, down, and right arrow keys.

window.onload = function() {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById('ss'), { sheetCount: 1 });
initSpread(spread);
};
function initSpread(spread) {
var sheet = spread.getActiveSheet();
spread.fromJSON(data[0]);
document.getElementById('addCToKeyMap').addEventListener('click', function() {
var spreadNS = GC.Spread.Sheets.Commands;
var commandManager = spread.commandManager();
commandManager.register(
'customNavigationUp',
spreadNS.navigationUp,
'W'.charCodeAt(0),
false,
false,
false,
false
);
commandManager.register(
'customNavigationLeft',
spreadNS.navigationLeft,
'A'.charCodeAt(0),
false,
false,
false,
false
);
commandManager.register(
'customNavigationDown',
spreadNS.navigationDown,
'S'.charCodeAt(0),
false,
false,
false,
false
);
commandManager.register(
'customNavigationRight',
spreadNS.navigationRight,
'D'.charCodeAt(0),
false,
false,
false,
false
);
});
}
