Kendo UI for jQuery数据管理使用教程:过滤器的全球化
Kendo UI目前最新提供Kendo UI for jQuery、Kendo UI for Angular、Kendo UI Support for React和Kendo UI Support for Vue四个控件。Kendo UI for jQuery是创建现代Web应用程序的最完整UI库。
小部件是一个统一的控件,用于筛选具有数据源的数据绑定组件。
概述
全球化进程结合组件消息的翻译(本地化)和使其适应特定的文化(国际化和支持从右到左),通过过滤器消息的本地化可以启用过滤器的全球化功能。
本地化
过滤器提供用于定义其过滤器运算符(例如包含、等于或大于)和逻辑消息(例如,AND和OR)的文本选项。
要本地化消息,请在messages字段中设置所需的字符串。要本地化运算符的名称,请列出可用的运算符,然后在operators字段中设置其文本。
<div id="filter"></div><ul id="listView"></ul> <script type="text/x-kendo-template" id="item"> <li> <strong>#= name #</strong>, aged #= age #, is on vacation: #= isOnLeave # </li> </script> <script> $(document).ready(function () { var dataSource = new kendo.data.DataSource({ data: [ { name: "Jane Doe", age: "25", isOnLeave: false }, { name: "John Doe", age: "33", isOnLeave: true }, { name: "John Smith", age: "37", isOnLeave: true }, { name: "Nathan Doe", age: 42, isOnLeave: false } ], schema: { model: { fields: { name: { type: "string" }, age: { type: "number" }, isOnLeave: { type: "boolean" } } } } }); $("#filter").kendoFilter({ dataSource: dataSource, messages: { or: "OR", // The OR main logic text. and: "AND", // The AND main logic text. apply: "Set Filter" // The APPLY button text. }, operators: { string: { eq: kendo.ui.Filter.fn.options.operators.string.eq, // Take the default Kendo UI text. contains: "Partially Matches" // Define a custom text. }, number: { gte: "Larger Than", // Define a custom text. lt: kendo.ui.Filter.fn.options.operators.number.lt // Take the default Kendo UI text. } }, expressionPreview: true, // Shows a text preview of the filter expression. applyButton: true, // Shows the built-in Apply button. fields: [ // Defining the fields is not mandatory. Otherwise, they will be taken from the data source schema. // If you define the fields, their names and types must match the data source definition. { name: "name", type: "string", label: "Name" }, { name: "age", type: "number", label: "Age" }, { name: "isOnLeave", type: "boolean", label: "On Vacation" } ], expression: { // defining an initial filter expression is not required logic: "and", filters: [ { field: "age", value: 30, operator: "gte" }, { field: "name", value: "Doe", operator: "contains" } ] } }).data("kendoFilter").applyFilter(); // Chain the method call to immediately apply filtering after the widget initialization because an initial filter is set. $("#listView").kendoListView({ dataSource: dataSource, template: kendo.template($("#item").html()) }); }); </script>
