解决方法

去www.json.org下载JSON2.js

再调用JSON.stringify(JSONData)将JSON对象转化为JSON串。

var people = [{ "UserName": "t1", "PassWord": "111111", "Sex": "男" }, { "UserName": "t2", "PassWord": "222222", "Sex": "女"}];

再构造URL回传给服务器端：

$("#btnSend").bind("click", function() {

$.post("a.ashx", {xxxx:JSON.stringify(people)}, function(data, returnstatus) { }, "json");

});

function customerCheck() {

                    selectRows = $("#ui_customerCheck_dg").datagrid('getSelections');

                    var jsonData = JSON.stringify(selectRows);

                    console.info(jsonData);

                    if (selectRows.length > 0) {

                        console.info(selectRows);

                        $.ajax({

                            url: 'ashx/bg_customerCheck.ashx?action=checkedPass',

                            data: { "selectRows": jsonData },

                            dataType: 'html',

                            success: function (rData) {

                                var dataJson = eval('(' + rData + ')');    //转成json格式

                                if (dataJson.success) {

                                    $.show_warning("提示", dataJson.msg);

                                    $("#ui_customerCheck_dg").datagrid("reload").datagrid('clearSelections').datagrid('clearChecked');

                                } else {

                                    $.show_warning("提示", dataJson.msg);

                                }

                            }

                        });

                    }

                    else {

                        $.show_warning("提示", "请选择需要审核的单据！");

                        return;

                    }

                    //console.info(selectRows);

                    //$("#ui_customerCheck_dg").datagrid('unselectAll');
