使用滑块选择进行过滤
您的项目可能需要您根据Slider选择来过滤ListView数据源，下面的示例演示如何实现此操作并显示包含或排除的过滤功能。
<div id="rangeslider1" class="slider">
<input />
<input />
</div>
<span> </span>
<div id="rangeslider2" class="slider">
<input />
<input />
</div>
<div id="listView"></div>
<div id="pager" class="k-pager-wrap"></div>
<script type="text/x-kendo-tmpl" id="template">
<div class="product">
<img src="https://demos.telerik.com/kendo-ui/content/web/foods/${ProductID}.jpg" alt="${ProductName} image" />
<h3>${ProductName}, $${UnitPrice}</h3>
<p>${kendo.toString(UnitPrice, "c")}</p>
</div>
</script>
<script>
var slider1 = $("#rangeslider1").kendoRangeSlider({
min: 1,
max: 77,
smallStep: 5,
largeStep: 10,
tickPlacement: "both",
change: function (e) {
var filters = [],
filter;
filters.push({field: "ProductID", operator: "gte", value: slider1.values()[0]});
filters.push({field: "ProductID", operator: "lte", value: slider1.values()[1]});
filters.push({field: "UnitPrice", operator: "gte", value: slider2.values()[0]});
filters.push({field: "UnitPrice", operator: "lte", value: slider2.values()[1]});
filter = {
logic: "and",
filters: filters
};
dataSource.filter(filter);
}
}).data("kendoRangeSlider");
var slider2 = $("#rangeslider2").kendoRangeSlider({
min: 1,
max: 77,
smallStep: 5,
largeStep: 10,
tickPlacement: "both",
change: function (e) {
var filters = [],
filter;
filters.push({field: "ProductID", operator: "gte", value: slider1.values()[0]});
filters.push({field: "ProductID", operator: "lte", value: slider1.values()[1]});
filters.push({field: "UnitPrice", operator: "gte", value: slider2.values()[0]});
filters.push({field: "UnitPrice", operator: "lte", value: slider2.values()[1]});
filter = {
logic: "and",
filters: filters
};
dataSource.filter(filter);
}
}).data("kendoRangeSlider");
var dataSource = new kendo.data.DataSource({
transport: {
read: {
url: "https://demos.telerik.com/kendo-ui/service/Products",
dataType: "jsonp"
}
}
});
$("#pager").kendoPager({
dataSource: dataSource
});
$("#listView").kendoListView({
dataSource: dataSource,
template: kendo.template($("#template").html())
});
</script>
</body>
在数据操作过程中保持行选择
下面的示例演示如何在ListView中的数据操作过程中保留行选择。
<div id="listview"></div>
<div id="pager"></div>
<script>
$(function () {
var dataSource = new kendo.data.DataSource({
type: "odata",
transport: {
read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Orders"
},
schema: {
model: {
id: "OrderID",
fields: {
OrderID: { type: "number" },
Freight: { type: "number" },
ShipName: { type: "string" },
OrderDate: { type: "date" },
ShipCity: { type: "string" }
}
}
},
pageSize: 10,
serverPaging: true
});
var selectedOrders = [];
var idField = "OrderID";
$("#listview").kendoListView({
dataSource: dataSource,
height: 400,
selectable: "multiple",
pageable: true,
template: "<div>#:ShipCity# || #:Freight# || #:kendo.toString(OrderDate, 'dd/MM/yyyy')#</div>",
change: function (e, args) {
var listview = e.sender;
var items = listview.items();
items.each(function (idx, row) {
var idValue = listview.dataSource.getByUid(row.dataset.uid).get(idField);
if (row.className.indexOf("k-state-selected") >= 0) {
selectedOrders[idValue] = true;
} else if (selectedOrders[idValue]) {
delete selectedOrders[idValue];
}
});
},
dataBound: function (e) {
var listview = e.sender;
var items = listview.items();
var itemsToSelect = [];
items.each(function (idx, row) {
var dataItem = listview.dataSource.getByUid(row.dataset.uid);
if (selectedOrders[dataItem[idField]]) {
itemsToSelect.push(row);
}
});
listview.select(itemsToSelect);
}
});
$("#pager").kendoPager({ dataSource: dataSource });
});
</script>
在DataSource Item Update上更新ListView
ListView不会在模型字段更新时动态更新内容，要重新渲染窗口小部件，请在模型更新后手动触发dataSource的change事件，下面的示例演示如何实现此操作。
