筛选行

你可以隐藏不符合条件的行。筛选按钮将会显示在可被筛选列的列标题上。用户可以点击按钮并自定义筛选器和排序规则。

用户可以使用鼠标和键盘快捷键来操作筛选对话框。

Esc 键与点击 “Cancel” 按钮的行为一致。

Tab 键可用于在筛选对话框中的不同区域之间来回移动。

上键和下键用于在列表中上移和下移。

空格键用于勾选和取消勾选选中行。

你可以使用 rowFilter 方法来给工作表创建一个筛选器。

你可以使用 filterButtonVisible 来隐藏筛选器按钮。

示例代码

以下代码创建了一个筛选器：

JavaScript

var cellrange =new GC.Spread.Sheets.Range(0, 2, 5, 1);
var hideRowFilter =new GC.Spread.Sheets.Filter.HideRowFilter(cellrange);
activeSheet.rowFilter(hideRowFilter);
//activeSheet.rowFilter(new GC.Spread.Sheets.Filter.HideRowFilter(new GC.Spread.Sheets.Range(0,0,4,4)));

示例代码

下列使用代码创建了一个筛选器规则。

JavaScript

$(function () {
            var workbook = new GC.Spread.Sheets.Workbook($("#ss")[0]);
            var activeSheet = workbook.getActiveSheet();
            activeSheet.setRowCount(7);
            activeSheet.setValue(0, 0, "North");
            activeSheet.setValue(1, 0, "South");
            activeSheet.setValue(2, 0, "East");
            activeSheet.setValue(3, 0, "South");
            activeSheet.setValue(4, 0, "North");
            activeSheet.setValue(5, 0, "North");
            activeSheet.setValue(6, 0, "West");
            activeSheet.setColumnWidth(0, 80);
            activeSheet.rowFilter(new GC.Spread.Sheets.Filter.HideRowFilter(new GC.Spread.Sheets.Range(0, 0, 7, 1)));
            $("#button1").click(function(){
                //Filter Column1 by "North".
                var rowFilter = $("#ss").data("workbook").getActiveSheet().rowFilter();
                var condition = new GC.Spread.Sheets.ConditionalFormatting.Condition(GC.Spread.Sheets.ConditionalFormatting.ConditionType.textCondition, {
                    compareType: GC.Spread.Sheets.ConditionalFormatting.TextCompareType.equalsTo,
                    expected: "North"
                });
                rowFilter.addFilterItem(0, condition);
                rowFilter.filter(0);
            });
            $("#button2").click(function(){
                // Remove filtering for Column1
                var rowFilter = $("#ss").data("workbook").getActiveSheet().rowFilter();
                if(rowFilter){
                    rowFilter.removeFilterItems(0);
                    rowFilter.filter();
                }
            });
        });
//Add button controls to page
<input type="button" id="button1" value="button1"/>
<input type="button" id="button2" value="button2"/>

示例代码

以下代码创建了一个自定义筛选器

JavaScript

//Create a custom condition.
        function CustomFilter(){
            GC.Spread.Sheets.ConditionalFormatting.Condition.apply(this, arguments);
            //this.conditionType("CustomFilter");
        };
        CustomFilter.prototype = new GC.Spread.Sheets.ConditionalFormatting.Condition();
        CustomFilter.prototype.evaluate = function (evaluator, row, col) {
            var value = evaluator.getValue(row, col);
            if (value !== null && value >= 10 && value <= 50) {
                //Return True only when the following conditions are satisfied.
                // (1)Values are entered.
                // (2)Values are not lower than 10.
                // (3)Values are not greater than 50.
                return true;
            } else {
                return false;
            }
        };
        $(function () {
            var workbook = new GC.Spread.Sheets.Workbook($("#ss")[0]);
            var activeSheet = workbook.getActiveSheet();
            activeSheet.setValue(0, 0, 10);
            activeSheet.setValue(1, 0, 100);
            activeSheet.setValue(2, 0, 50);
            activeSheet.setValue(3, 0, 40);
            activeSheet.setValue(4, 0, 80);
            activeSheet.setValue(5, 0, 1);
            activeSheet.setValue(6, 0, 65);
            activeSheet.setValue(7, 0, 20);
            activeSheet.setValue(8, 0, 30);
            activeSheet.setValue(9, 0, 35);
            $("#button1").click(function(){
                //Set a row Filter.
                var rowFilter = new GC.Spread.Sheets.Filter.HideRowFilter(new GC.Spread.Sheets.Range(0, 0, 7, 1));
                activeSheet.rowFilter(rowFilter);
                rowFilter.addFilterItem(0, new CustomFilter());
                rowFilter.filter(0);
            });
        });

// Add a button at the bottom of the page
<input id="button1" type="button" value="Button1"/>
