我有一个内部的一个Ajax的UpdatePanel自动生成的图像。此图片是从服务器端code生成的图表。搜索在谷歌,我意识到这是FF的错误。任何人都不会有什么解决办法?
下面是源(它也包含不需要的标签,我只是复制粘贴)

解决方案
此外,它是不是一个很好的解决方案,设置缓存能力为nocache解决了我的问题。我又写道这对我的页面加载
Response.Cache.SetCacheability(HttpCacheability.NoCache);
它也可以通过设置此code
<脚本类型=文/ JavaScript的>
变种PRM = Sys.WebForms.PageRequestManager.getInstance();
prm.add_pageLoaded(为pageLoaded);
变种C = 0;
功能为pageLoaded(发件人,参数)
{
VAR IMG =的document.getElementById(ctl00_ctl00_MainContent_MainContent_chartExchange);
C ++;
img.src = img.src +? + C;
}
< / SCRIPT>
I have an image that is generated automatically inside an Ajax UpdatePanel. This image is a graph that is generated from server-side code. Searching in Google, I realised it was a bug of FF. Does anybody have any solution?
Here is the source (it contains also unneeded tags, I just copied-paste)
<div>
<asp:UpdatePanel ID="UpdatePanelGraph" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Panel ID="pnlGraph" runat="server" CssClass="container">
<div id="chart">
<Web:ChartControl ID="chartExchange" runat="server" Width="300px" Height="200px" BorderStyle="None" GridLines="both" DefaultImageUrl="../images/noData.png" ShowTitlesOnBackground="False" BorderWidth="1px" Padding="1" HasChartLegend="False" BottomChartPadding="20" TopChartPadding="5" RightChartPadding="5" LeftChartPadding="20">
<Border Color="211, 224, 242"></Border>
<YAxisFont ForeColor="115, 138, 156" Font="Tahoma, 7pt" StringFormat="Far,Center,Character,LineLimit"></YAxisFont>
<XTitle ForeColor="115, 138, 156" StringFormat="Center,Near,Character,LineLimit">
</XTitle>
<XAxisFont ForeColor="115, 138, 156" StringFormat="Near,Near,Character,NoClip"></XAxisFont>
<Background Type="LinearGradient" Color="#C9DEFD" ForeColor="Transparent" EndPoint="500, 500">
</Background>
<ChartTitle ForeColor="51, 51, 51" Font="Verdana, 9pt, style=Bold" StringFormat="Near,Near,Character,LineLimit">
</ChartTitle>
<Charts>
<Web:SmoothLineChart Name="buy" Legend="Blen">

</asp:UpdatePanel>
</div>
解决方案
Also it is not a good solution, setting the cacheability to nocache resolved my problem. I worte this on my pageload
Response.Cache.SetCacheability(HttpCacheability.NoCache);
It also works by setting this code
<script type="text/javascript">
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_pageLoaded(pageLoaded);
var c = 0;
function pageLoaded(sender, args)
{
var img = document.getElementById("ctl00_ctl00_MainContent_MainContent_chartExchange");
c++;
img.src = img.src + "?" + c;
}
</script>
