MVC中使用ajax传递json数组

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');
}
