我正在研究asp mvc應用程序。 我正在根據數據庫中的數據生成圖表。 當我點擊去按鈕我有調用getReportData（）函數，從數據庫中提取結果並設置圖表圖像。控制器功能不被稱爲secound時間
當我第一次調用我的功能工作正常，但secound時間只有網格數據顯示，我的意思是生成圖像的函數不是第二次調用，我試圖調試它，但只有第一次，我正在調試不是第二次。
function getReportData() {

$('#span_pie_result').css('display','none');
var report='ProductNameBatch';
var subreport='Non-FaceBook';
if(report.toLowerCase()=='ctss')
{
alert('Report is temporarily Un-available');
return;
}
if (parent.top.$("input#from_date").val() == "" || parent.top.$("input#to_date").val() == "") {
alert("Invalid Date Range !!!");
return;
}

//register call back functionality invoked when result image response complete
$('img[id^="img_barchart_result"]').bind('load',function(){
onLoadComplete('bar');
});
$('img[id^="img_piechart_result"]').bind('load',function(){
onLoadComplete('pie');
});
}
這裏是我的控制功能提前
public FileResult fetchChartReport(SeriesChartType chartType, string from_date, string to_date, string report, string subreport,string reporttitle,string displayformat, string filterParamList)
{
try
{
Chart chart = new Chart();
string repportlistid = "chart-" + report.ToLower() + "-" + subreport.ToLower();
//List<string> reportNameList= GetParameterListById(repportlistid);
//return View();
reportObject = getReportInstance(report);
chart = reportObject.getChartReport(chartType, from_date, to_date, report.ToLower(), subreport.ToLower(), reporttitle,displayformat, filterParamList);
MemoryStream ms = new MemoryStream();
chart.SaveImage(ms);
return File(ms.GetBuffer(), @"image/png");
}
catch (Exception ex)
{
return File(Server.MapPath(Url.Content("~/Content/dashboard/images/dash_no_data.jpg")), "image/jpg");
}
}
