ColorPicker

ColorPicker is a type of drop-down in SpreadJS. Using JavaScript code, the developer can define either the default or custom color picker as a style that can be applied to cells in the workbook. The below spreadsheet shows those two variations.

Drop-downs provides developer the ability to add a drop-down menu with specific properties to cells in a workbook. These drop-down menus don't require any extra code other than simply specifying which one to use for the drop-down menu. SpreadJS now has 8 different kinds of drop-downs, and this demo shows how to use the ColorPicker. You can use ColorPicker drop-down like the following code : If you want to customize the ColorPicker, you can use these options : colorBlockSize: number : Specific every color cell's size. groups: IColorGroup[] : Specific the group of the color picker, every group accept a name as group name, and a color array as the group's colors. needScaleColor: boolean : Specific whether generate scale color group. For example:
var spreadNS = GC.Spread.Sheets; window.onload = function () { var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss")); initSpread(spread); }; function initSpread(spread) { // -------------------- Default Calculator --------------------- var sheet = spread.getSheet(0); sheet.suspendPaint(); var style = new GC.Spread.Sheets.Style(); style.cellButtons = [ { imageType: GC.Spread.Sheets.ButtonImageType.dropdown, command: "openColorPicker", useButtonStyle: true, } ]; sheet.setText(4, 3, "Default Color Picker"); sheet.setStyle(5, 3, style); // -------------------- Custom Calculator --------------------- var colorGroup1 = { name: 'group1', colors: [ ['#ffffff', '#000000', '#e7e6e6', '#44546a', '#5b9bd5', '#ed7d31', '#a5a5a5', '#ffc000', '#4472c4', '#70ad47'], ['#f2f2f2', '#7f7f7f', '#d1d0d0', '#d6dde4', '#dfebf6', '#fae6d7', '#ececec', '#fdf3ce', '#dae3f2', '#e3efda'] ] }; var colorGroup2 = { name: 'group2', colors: [ ['#d8d8d8', '#595959', '#aeadac', '#aeb9c8', '#c0d7ed', '#f4ccaf', '#dadada', '#fce69d', '#b6c7e6', '#c8dfb5'], ['#bfbfbf', '#3f3f3f', '#777171', '#8797ae', '#9fc3e4', '#f0b186', '#c8c8c8', '#fbd96c', '#91acda', '#add091'] ] }; var colorGroup3 = { name: 'group3', colors: [ ['#a5a5a5', '#252525', '#3c3939', '#344051', '#3977b6', '#c35a15', '#7c7c7c', '#bd9014', '#355696', '#5a8339'], ['#7f7f7f', '#0b0b0b', '#171615', '#222a35', '#264f79', '#823c0d', '#525252', '#7e600a', '#223a64', '#3b5825'] ] }; var customStyle = new GC.Spread.Sheets.Style(); customStyle.cellButtons = [ { imageType: GC.Spread.Sheets.ButtonImageType.dropdown, command: "openColorPicker", useButtonStyle: true, } ]; customStyle.dropDowns = [ { type: GC.Spread.Sheets.DropDownType.colorPicker, option: { colorBlockSize: 20, groups: [ colorGroup1, colorGroup2, colorGroup3 ] } } ]; sheet.setText(4, 11, "Custom Color Picker"); sheet.setStyle(5, 11, customStyle); sheet.resumePaint(); spread.commandManager().execute({cmd:"openColorPicker",row:5,col:3,sheetName:"Sheet1"}); // spread.commandManager().execute({cmd:"openColorPicker",row:5,col:11,sheetName:"Sheet1"}); }
