Spread 인스턴스에서 탐색하는 데 의존하는 비즈니스 논리가 있는 경우 유용할 수 있습니다.
moveToNextCell: 다음 셀로 이동합니다(Tab의 기본 동작).
moveToPreviousCell: 이전 셀로 이동합니다(Shift + Tab의 기본 동작).
selectNextControl: spread.nextControl 지정된 요소 또는 설정되지 않은 경우 자동 감지된 요소를 선택합니다.
selectPreviousControl: spread.previousControl 지정된 요소 또는 설정되지 않은 경우 자동 감지된 요소를 선택합니다.
moveToNextCellThenControl: 활성 셀이 표시 가능한 마지막 셀인 경우 다음 셀로 이동하고 다음 컨트롤을 선택합니다.
moveToPreviousCellThenControl: 활성 셀이 표시 가능한 첫 번째 셀인 경우 이전 셀로 이동하고 이전 컨트롤을 선택합니다.
nextControl 및 previousControl 메서드를 사용하여 선택한 컨트롤을 설정할 수 있습니다. 예:
Spread는 사용자 지정 명령을 생성할 수 있습니다. 예:
register 메서드를 사용하여 네비게이션 키 및 해당 작업을 설정합니다. 예:
register 인수의 순서는 다음과 같습니다:
name: 명령의 이름입니다.
execute: 명령의 실행 함수입니다.
key: 키의 유니코드입니다.
ctrl: 작업에 Ctrl 키를 사용하는 경우 true이고, 그렇지 않으면 false입니다.
shift: 작업에 Shift 키를 사용하는 경우 true이고, 그렇지 않으면 false입니다.
alt: 작업에 Alt 키를 사용하는 경우 true이고, 그렇지 않으면 false입니다.
meta: 작업에 Macintosh의 Command 키 또는 Microsoft Windows의 Windows 키를 사용하는 경우 true이고, 그렇지 않으면 false입니다.
hideSelection 옵션을 사용하여 Spread가 포커스를 잃을 때 선택 항목을 숨깁니다. 예:
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 1 });
initSpread(spread);
};
function initSpread(spread) {
var sheet = spread.getSheet(0);
spread.suspendPaint();
sheet.setRowCount(20);
sheet.setColumnCount(10);
sheet.addSpan(0, 0, 1, 7);
sheet.setValue(0, 0, "press the \'Tab\' or \'Shift + Tab\' key, the selction will move in accordance.");
for (var i = 1; i < 20; i += 3) {
for (var j = 1; j < 20; j += 3) {
sheet.setValue(i, j, "Test");
}
}
