当为工作表设置筛选时，首先需要创建一个行筛选，然后调用 rowFilter 方法来设置这个行筛选。
你也可以创建一个条件并且调用 addFilterItem 方法来为行筛选添加一个特殊的筛选。例如：
var spreadNS = GC.Spread.Sheets;
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
initSpread(spread);
};
function initSpread(spread) {
var sheet = spread.getSheet(0);
sheet.suspendPaint();
sheet.setRowCount(50);
sheet.setColumnCount(8);
var rc = sheet.getRowCount();
var cc = sheet.getColumnCount();
for (var r = 0; r < rc; r++) {
for (var c = 0; c < cc; c++) {
if (c == 0) {
sheet.setValue(r, c, "Value is Number");
} else {
sheet.setValue(r, c, r + c);
}
}
}
sheet.setValue(0, 0, "Conditions", spreadNS.SheetArea.colHeader);
sheet.setValue(0, 1, "Cell Value", spreadNS.SheetArea.colHeader);
sheet.setValue(1, 0, "Text contains e");
sheet.setValue(10, 0, "Text doesn't contains e");
sheet.setValue(21, 0, "Text contains e");
sheet.setValue(1, 1, "begin");
sheet.setValue(10, 1, "during");
sheet.setValue(21, 1, "end");
sheet.setValue(2, 0, "Background is Cyan");
sheet.setValue(6, 0, "Background is Purple");
sheet.setValue(12, 0, "Background is Cyan");
sheet.getCell(2, 1).backColor("Cyan");
sheet.getCell(6, 1).backColor("Purple");
sheet.getCell(12, 1).backColor("Cyan");
sheet.setValue(3, 0, "Value is Thursday");
sheet.setValue(8, 0, "Value is Friday");
sheet.setValue(14, 0, "Value is Thursday");
sheet.setValue(3, 1, new Date(2011, 5, 30));
sheet.setValue(8, 1, new Date(2011, 6, 1));
sheet.setValue(14, 1, new Date(2011, 5, 30));
sheet.setValue(4, 0, "Value is null");
sheet.setValue(9, 0, "Value is null");
sheet.setValue(18, 0, "Value is null");
sheet.setValue(4, 1, null);
sheet.setValue(9, 1, null);
sheet.setValue(18, 1, null);
sheet.setColumnWidth(0, 150);
sheet.setColumnWidth(1, 150);
var filter = new spreadNS.Filter.HideRowFilter(new spreadNS.Range(-1, 0, -1, 2));
sheet.rowFilter(filter);
filter.filterButtonVisible(false);
sheet.resumePaint();
_getElementById("text_condition").addEventListener('click',function () {
var sheet = spread.getActiveSheet();
var filter = sheet.rowFilter();
if (filter) {
filter.removeFilterItems(1);
if (this.checked) {
var condition = new spreadNS.ConditionalFormatting.Condition(spreadNS.ConditionalFormatting.ConditionType.textCondition, {
compareType: spreadNS.ConditionalFormatting.TextCompareType.contains,
expected: "*e*"
});
filter.addFilterItem(1, condition);
}
filter.filter(1);
sheet.invalidateLayout();
sheet.repaint();
}
});
_getElementById("number_condition").addEventListener('click',function () {
var sheet = spread.getActiveSheet();
var filter = sheet.rowFilter();
if (filter) {
filter.removeFilterItems(1);
if (this.checked) {
var condition = new spreadNS.ConditionalFormatting.Condition(spreadNS.ConditionalFormatting.ConditionType.numberCondition, {
compareType: spreadNS.ConditionalFormatting.GeneralComparisonOperators.lessThan,
expected: 20
});
filter.addFilterItem(1, condition);
}
filter.filter(1);
sheet.invalidateLayout();
sheet.repaint();
}
});
_getElementById("date_condition").addEventListener('click',function () {
var sheet = spread.getActiveSheet();
var filter = sheet.rowFilter();
if (filter) {
filter.removeFilterItems(1);
if (this.checked) {
var dateExCondition = spreadNS.ConditionalFormatting.Condition.fromWeek(4);
filter.addFilterItem(1, dateExCondition);
}
filter.filter(1);
sheet.invalidateLayout();
sheet.repaint();
}
});
_getElementById("style_condition").addEventListener('click',function () {
var sheet = spread.getActiveSheet();
var filter = sheet.rowFilter();
if (filter) {
filter.removeFilterItems(1);
if (this.checked) {
var condition = new spreadNS.ConditionalFormatting.Condition(spreadNS.ConditionalFormatting.ConditionType.colorCondition, {
compareType: spreadNS.ConditionalFormatting.ColorCompareType.backgroundColor,
expected: "Cyan"
});
filter.addFilterItem(1, condition);
}
filter.filter(1);
sheet.invalidateLayout();
sheet.repaint();
}
});
_getElementById("custom_condition").addEventListener('click',function () {
var sheet = spread.getActiveSheet();
var filter = sheet.rowFilter();
if (filter) {
filter.removeFilterItems(1);
if (this.checked) {
var formulaCondition = new spreadNS.ConditionalFormatting.Condition(spreadNS.ConditionalFormatting.ConditionType.formulaCondition, {
customValueType: spreadNS.ConditionalFormatting.CustomValueType.empty,
formula: null
});
filter.addFilterItem(1, formulaCondition);
}
filter.filter(1);
sheet.invalidateLayout();
sheet.repaint();
}
});
}
function _getElementById(id){
return document.getElementById(id);
