1、將dt序列化成json，放到前臺的隱藏控件【hidBoundary】中：

復制代碼 代碼如下:

string json = JsonConvert.SerializeObject(dtTemp);
this.hidBoundary.Value = json;

復制代碼 代碼如下:

var boundaryDiv = $('#hidBoundary');
if (boundaryDiv != undefined && boundaryDiv.length != 0)
{
var jsonString = boundaryDiv.val();
_jsonBoundary = jQuery.parseJSON(jsonString);
}
