json各种我们都知道 {"key1":"value1","key2":"value2"} 前端js代码如下:

$.post("InternalBillHandle.ashx",  function (data, textStatus, jqXHR) {                 $("#totalInternal").text(data.totalInternal);                $("#successInternal").text(data.successInternal);                $("#failInternal").text(data.failInternal);                $("#successExpense").text(data.successExpense);                $("#failExpense").text(data.failExpense);            }, "json");

后台拼接的json如下:

var ret = "{'totalInternal':" + totalDataTable.Rows.Count + ",'successInternal':" + internalBillsSuccessfullyDataTable.Rows.Count + ",'failInternal':" + internalBillsFailureDataTable.Rows.Count + ",'successExpense':" + expenseItemSuccessfulDataTable.Rows.Count + ",'failExpense':" + expenseItemFailureDataTable.Rows.Count + "}";

问题来了,现在始终触发不了jq的回调函数, 这是为什么呢, 原因是他的引号, 我将代码改成下面就能触发:

var ret = "{\"totalInternal\":" + totalDataTable.Rows.Count + ",\"successInternal\":" + internalBillsSuccessfullyDataTable.Rows.Count + "}";
