Data grid footers

Footers in Jspreadsheet allow you to display information or calculations at the bottom of a data grid. This section provides instructions for implementing footers during initialization or runtime using programming techniques.

Documentation

Methods

The following methods provide programmatic interaction with the footers of the Jspreadsheet data grid.

Method Description
getFooter() Get the current footer settings.
getFooter() : Array
setFooter() Set the footer settings.
setFooter(newValue: Array) : void
resetFooter() Reset and remove the footers.
resetFooter() : void
refreshFooter() Recalculate the values in the footer.
refreshFooter() : void
getFooterValue(number, number) Get the current footer cell value from the coordinates x, y.
getFooterValue(x: Number, y: Number) : void
setFooterValue(number, number, string) Set the value of a footer cell to the coordinates x, y.
setFooterValue(x: Number, y: Number, value: String) : void

Events

The following events allow you to intercept user interactions with the Jspreadsheet data grid.

Event Description
onchangefooter This method is invoked when the footers undergo modification in the Jspreadsheet data grid.
onchangefooter(worksheet: Object, newValue: String, oldValue: String) : null
onchangefootervalue This method is called when the values of the footers in the Jspreadsheet data grid are modified.
onchangefootervalue(worksheet: Object, x: Number, y: Number, newValue: String) : null
onrenderfootercell
This method is called when a footer cell is rendered. onrenderfootercell(worksheet: Object, x: Number, y: Number, newValue: String, td: HTMLElement) : null

Initial Settings

The following property is available during the initialization of the Jspreadsheet online spreadsheet.

Property Description
footers: string[] Footers definitions

Examples

Basic footer usage

In the example below the custom SUMCOL formula is implemented to consider only visible rows in the calculations.

Cross footer calculations

Footers are used to hold static information, but the following example creates a complete cross-footer calculations with realtime updates using onafterchanges. See our cross spreadsheet footer calculations on jsfiddle
