如何在devextreme中使用ajax发送选定的datagrid对象

<div id="gridContainer"></div>

<script>
    $(function() {
        $("#gridContainer").dxDataGrid({
            dataSource: yourDataSource,
            columns: yourColumns,
            selection: {
                mode: "multiple",
                showCheckBoxesMode: "always"
            }
        });
    });
</script>

<button id="sendButton">发送选定的对象</button>

$(function() {
    $("#sendButton").click(function() {
        var selectedRows = $("#gridContainer").dxDataGrid("instance").getSelectedRowsData();
        
        $.ajax({
            url: "yourServerUrl",
            type: "POST",
            data: JSON.stringify(selectedRows),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function(response) {
                // 处理成功响应
            },
            error: function(xhr, status, error) {
                // 处理错误响应
            }
        });
    });
});
