使用 Date Occurring 规则

Date Occurring 规则是用来比对日期的。以下代码使用了 Date Occurring 规则。

var style = new GC.Spread.Sheets.Style();
style.backColor = "red";
var rule = new GC.Spread.Sheets.ConditionalFormatting.NormalConditionRule(GC.Spread.Sheets.ConditionalFormatting.RuleType.DateOccurringRule, [new GC.Spread.Sheets.Range(0,0,10,1)], style, null, null, null, null, null, GC.Spread.Sheets.ConditionalFormatting.DateOccurringType.NextWeek);
activeSheet.conditionalFormats.addRule(rule);
var d = new Date();
activeSheet.setValue(0, 0, d);
activeSheet.setValue(1, 0, new Date(d.setDate(d.getDate()+1)));
activeSheet.setValue(2, 0, new Date(d.setDate(d.getDate()+5)));
activeSheet.setValue(3, 0,new Date(d.setDate(d.getDate()+6)));
activeSheet.setValue(4, 0,new Date(d.setDate(d.getDate()+7)));
activeSheet.setValue(5, 0, new Date(d.setDate(d.getDate()+8)));
// OR
var style = new GC.Spread.Sheets.Style();
style.backColor = "red";
activeSheet.conditionalFormats.addDateOccurringRule(GC.Spread.Sheets.ConditionalFormatting.DateOccurringType.NextWeek, style, [new GC.Spread.Sheets.Range(0,0,10,1)]);
var d = new Date();
activeSheet.setValue(0, 0, d);
activeSheet.setValue(1, 0, new Date(d.setDate(d.getDate()+1)));
activeSheet.setValue(2, 0, new Date(d.setDate(d.getDate()+5)));
activeSheet.setValue(3, 0,new Date(d.setDate(d.getDate()+6)));
activeSheet.setValue(4, 0,new Date(d.setDate(d.getDate()+7)));
activeSheet.setValue(5, 0, new Date(d.setDate(d.getDate()+8)));

使用 Duplicate 规则

Duplicate 规则用于检查单元格中重复的值。

示例代码

以下代码使用了 duplicate 规则。

var style = new GC.Spread.Sheets.Style();
style.backColor = "yellow";
var ranges=[new GC.Spread.Sheets.Range(0,0,10,1)];
activeSheet.conditionalFormats.addDuplicateRule(style, ranges);
activeSheet.setValue(0, 0, 50);
activeSheet.setValue(1, 0, 50);
activeSheet.setValue(2, 0, 11);
activeSheet.setValue(3, 0, 5);
// OR
var style = new GC.Spread.Sheets.Style();
style.backColor = "yellow";
var rule = new GC.Spread.Sheets.ConditionalFormatting.NormalConditionRule();
rule.ruleType(GC.Spread.Sheets.ConditionalFormatting.RuleType.DuplicateRule);
rule.ranges([new GC.Spread.Sheets.Range(0,0,10,1)]);
rule.style(style);
activeSheet.conditionalFormats.addRule(rule);
activeSheet.setValue(0, 0, 50);
activeSheet.setValue(1, 0, 50);
activeSheet.setValue(2, 0, 11);
activeSheet.setValue(3, 0, 5);
