如何“使用具有一些默认选择的多复选框筛选器在serverSide上筛选Kendo Grid数据”

// 前端页面代码
$("#grid").kendoGrid({
  dataSource: {
    transport: {
      read: {
        url: "/api/data", // 数据获取接口
        dataType: "json"
      }
    },
    serverPaging: true,
    serverFiltering: true,
    pageSize: 10
  },
  columns: [
    { field: "id", title: "ID" },
    { field: "name", title: "Name" },
    { field: "category", title: "Category" }
  ],
  filterable: {
    extra: false,
    operators: {
      string: {
        contains: "包含",
        eq: "等于"
      }
    }
  },
  pageable: true
});

$("#filterButton").click(function() {
  var selectedValues = $("#multiSelect").data("kendoMultiSelect").value();
  
  // 将选择的筛选条件传递给服务器端
  $.ajax({
    url: "/api/filter",
    type: "POST",
    data: { filters: selectedValues },
    success: function(result) {
      // 更新Kendo Grid的数据源，显示筛选后的数据
      var grid = $("#grid").data("kendoGrid");
      grid.dataSource.data(result);
    }
  });
});

// 服务器端代码（示例使用Node.js和Express框架）
app.get("/api/data", function(req, res) {
  // 从数据库或其他数据源获取数据
  var data = [
    { id: 1, name: "产品A", category: "类别1" },
    { id: 2, name: "产品B", category: "类别2" },
    { id: 3, name: "产品C", category: "类别1" },
    { id: 4, name: "产品D", category: "类别3" }
  ];
  
  res.json(data);
});

app.post("/api/filter", function(req, res) {
  var filters = req.body.filters;
  
  // 根据筛选条件对数据进行筛选
  var filteredData = data.filter(function(item) {
    return filters.includes(item.category);
  });
  
  res.json(filteredData);
});
