Data Grid Keyboard Shortcuts

This section provides more information on the existing keyboard shortcuts and how to customize them in Jspreadsheet. Version 11 introduces a shortcut configuration tool allowing developers to create or adjust shortcuts to suit specific application requirements. Below is a table showcasing the keyboard shortcuts currently available.

Customizing Shortcuts in Jspreadsheet

Jspreadsheet version 11 features a new shortcut management. This feature allows developers to tailor or add keyboard shortcuts to customize jspreadsheet to their application needs.

Shortcut Execution Context

Upon activating a keyboard shortcut, Jspreadsheet verifies the presence of a corresponding custom declaration. If a match is found, the shortcut is executed with this context linked to the specific worksheet where the action is performed.

let paste = function(e) {
    if (! e.target.classList.contains('jss_object')) {
        let s = Selection.get.call(this);
        if (s) {
            let worksheet = this;
            navigator.clipboard.readText().then(function(text) {
                if (text) {
                    worksheet.paste(s[0], s[1], text, true);
                }
            });
        }
    }
}

let shortcuts = {
    ctrlKey: {
        A: function() { this.selectAll(); },
        C: function() { this.copy(); },
        X: function() { this.cut(); },
        P: function() { this.print(); },
        S: function() { this.download(); },
        Z: function() { this.undo(); },
        Y: function() { this.redo(); },
        F: function() { this.showSearch(); },
        '-': function(e, event) {
            if (event.role === 'row') {
                this.deleteRow();
            } else if (event.role === 'header') {
                this.deleteColumn();
            }
        },
        ENTER: paste
    },
    shiftKey: {}, // If you have shiftKey shortcuts, add them here
    PAGEUP: function() { this.pageUp(); },
    PAGEDOWN: function() { this.pageDown(); },
    ARROWUP: function(e) { this.up(e.shiftKey, (e.ctrlKey || e.metaKey)); },
    ARROWDOWN: function(e) {
        let col = this.selectedCell[e.shiftKey ? 2 : 0];
        if (e.altKey && (this.options.filters || (this.cols[col] && this.cols[col].filter))) {
            this.openFilter(col);
        } else {
            this.down(e.shiftKey, (e.ctrlKey || e.metaKey));
        }
    },
    ARROWLEFT: function(e) { this.left(e.shiftKey, (e.ctrlKey || e.metaKey)); },
    ARROWRIGHT: function(e) { this.right(e.shiftKey, (e.ctrlKey || e.metaKey)); },
    HOME: function(e) { this.first(e.shiftKey, (e.ctrlKey || e.metaKey)); },
    END: function(e) { this.last(e.shiftKey, (e.ctrlKey || e.metaKey)); },
    ENTER: function(e) {
        if (e.shiftKey) {
            this.up();
        } else {
            if (this.selectedCell[1] === this.rows.length-1 &&
                this.options.allowManualInsertRow !== false) {
                // Create a new row
                this.insertRow();
            }
            this.down();
        }
    },
    TAB: function(e) {
        if (e.shiftKey) {
            this.left();
        } else {
            if (this.selectedCell[0] === this.cols.length-1 &&
                this.options.allowManualInsertColumn !== false) {
                // Create a new row
                this.insertColumn();
            }
            this.right();
        }
    },
    DELETE: function() {
        this.setValue(this.getSelected(), '');
    },
    F2: function(e) {
        if (this.selectedCell && this.selectedCell.length) {
            let cell = this.getCell(...this.selectedCell);
            if (cell) {
                this.openEditor(cell, false, e);
            }
        }
    }
}

Adding a new custom shortcut

To add a new custom shortcut in Jspreadsheet to trigger a custom plugin to print the spreadsheet content, you'll need to define the shortcut as the example below:

jspreadsheet.shortcuts.ctrlKey.P = function(e) {
    // This will be the worksheet
    let worksheet = this;
    // Get the worksheet data
    let data = worksheet.getData();
    // Call custom plugin
    myCustomPrintPlugin(data);
}
