你可以调用 repaint 方法来重新绘制表单。
大多数时候, 在你改变表单之后, 控件会自动刷新以达到重绘和更新状态的目的。可是, 如果你一次做出大量的改变, 并且不希望每次改变都去重新绘制表单 , 那么你可以调用 suspendPaint方法来挂起重绘机制。当你完成了所有的改变之后, 你可以调用 resumePaint 方法来重新激活重绘机制。例如:
window.onload = function() {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), {
sheetCount: 1
});
var spreadNS = GC.Spread.Sheets;
document.getElementById("setValue").addEventListener('click',function() {
var sheet = spread.getActiveSheet();
var cellRange = sheet.getSelections()[0];
var salesData = [
["Salesperson", "Region", "Sales Amount", "Commission %", "Commission Amount"],
["Joe", "North", 260, '10%', 26],
["Robert", "South", 660, '15%', 99],
["Michelle", "East", 940, '15%', 141],
["Erich", "West", 410, '12%', 49.2],
["Dafna", "North", 800, '15%', 120],
["Rob", "South", 900, '15%', 135]
];
if (cellRange) {
for (var row = cellRange.row, rowCount = cellRange.row + cellRange.rowCount; row < rowCount; row++) {
for (var col = cellRange.col, colCount = cellRange.col + cellRange.colCount; col < colCount; col++) {
sheet.setArray(row, col, salesData);
sheet.getCell(row, col).foreColor("lightGreen");
sheet.getCell(row, ++col).foreColor("lightGreen");
sheet.getCell(row, ++col).foreColor("lightGreen");
sheet.getCell(row, ++col).foreColor("lightGreen");
sheet.getCell(row, ++col).foreColor("lightGreen");
}
}
}
});
document.getElementById("suspendPaint").addEventListener('click',function() {
spread.suspendPaint();
});
document.getElementById("resumePaint").addEventListener('click',function() {
spread.resumePaint();
});
};
