如何在剑道网格中获得可用的高度

Question

如何在剑道网格中获得可用的高度？ 这意味着我正在动态地将项目添加到网格中，所以我需要动态的网格高度

Answer 1

您可以通过

询问wrapper（完整网格）或tbody（网格的内部）的height来查询它，具体取决于您想要的内容：

// Get a reference to the KendoUI Grid object
var grid = $("#grid").data("kendoGrid");
// Ask the height of the Grid
alert("Height of Grid: " + grid.wrapper.height())
// Ask the height of the body (total rows) of the Grid
alert("Height of the body of the Grid: " + grid.tbody.height());

重要提示：如果部分行处于隐藏状态，并且您必须滚动才能看到它们，则网格的主体可能大于网格本身。

例。

$(document).ready(function() {
  $("#show").on("click", function() {
    var grid = $("#grid").data("kendoGrid");
    alert("Grid: " + grid.wrapper.height() + "n" + 
          "Body: " + grid.tbody.height());
  });
  $("#grid").kendoGrid({
    dataSource: {
      data: products,
      schema: {
        model: {
          fields: {
            ProductName: { type: "string" },
            UnitPrice: { type: "number" },
            UnitsInStock: { type: "number" },
            Discontinued: { type: "boolean" }
          }
        }
      },
      pageSize: 20
    },
    pageable: true,
    height: 300,
    columns: [
      "ProductName",
      { field: "UnitPrice", title: "Unit Price", format: "{0:c}", width: "130px" },
      { field: "UnitsInStock", title: "Units In Stock", width: "130px" },
      { field: "Discontinued", width: "130px" }
    ]
  });
});
