var r = {
init : function(){
r = Raphael("pie");
//r.g.txtattr.font = "12px 'Fontin Sans', Fontin-Sans, sans-serif";
r.g.text(320, -330, "Message Status").attr({ "font-size": 20 });
var pie = r.g.piechart(360, -180, 100, <%= Session["uStats"] %>, { legend: [<%= Session["vkeyColor"] %>], colors: [<%= Session["vPieColor"] %>] });
pie.hover(function () {
this.sector.stop();
this.sector.scale(1.1, 1.1, this.cx, this.cy);
if (this.label) {
this.label[0].stop();
this.label[0].scale(1.5);
this.label[1].attr({ "font-weight": 800 });
}
}, function () {
this.sector.animate({ scale: [1, 1, this.cx, this.cy] }, 500, "bounce");
if (this.label) {
this.label[0].animate({ scale: 1 }, 500, "bounce");
this.label[1].attr({ "font-weight": 400 });
}
});
var r = Raphael("pie"),
data2 = [<%= Session["vProgressPercentage"] %>];
axisx = ["10%", "20%"];
r.g.txtattr.font = "12px 'Fontin Sans', Fontin-Sans, sans-serif";
r.g.barchart(80, 25, 100, 320, data2, { stacked: true, colors: [<%= Session["vProgressColor"] %>,'#fff'] });
axis2 = r.g.axis(94, 325, 280, 0, 100, 10, 1);
}
}
window.onload = function () {
r.init();
};
Javascript在页面加载时执行,我使用更新面板进行部分回发,Javascript在回发期间不执行,如何从服务器端调用它。
<asp:ScriptManager ID="smCharts" runat="server" />
<script type="text/javascript" language="javascript">
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler);
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function BeginRequestHandler(sender, args) {
r.init();
}
function EndRequestHandler(sender, args) {
r.init();
}
</script>
<asp:UpdatePanel runat="server" ID="Holder" OnLoad="messsagePercentStats" UpdateMode="Conditional">
<ContentTemplate>
<div id="pie" onclick="__doPostBack('Holder', '');" style="top: -125px; left: -20px; width: 610px; position: relative;
height: 389px;">
</div>
这就是我正在尝试的,图表没有改变。它保持不变,就像页面加载
protected void Timer_Tick(object sender, EventArgs args)
{
String MsgID = HttpContext.Current.Request.QueryString["MsgID"];
int msgID = Convert.ToInt32(MsgID);
BindGridViewUsers(msgID);
ClientScript.RegisterStartupScript(this.GetType(), "loadpie", "r.init();");
Holder.Update();
}
使用ScriptManager。RegisterStartupScript从更新面板调用javascript函数;像这样:
ScriptManager.RegisterStartupScript(this,this.GetType(),"key","javscriptfunction();" , false);
您可以将此脚本放入函数中:
function foo() {
...
}
将在DOM加载时执行:
window.onload = function () {
foo();
};
和在服务器端从UpdatePanel回发时:
ScriptManager.RegisterStartupScript(this, this.GetType(), "foo", "foo();", true);
window.onload
在页面已经加载后不工作。使用
$(function(){ r.init();})
。
你也可以做
Response.Write("<script language='javascript'>alert('I'm an alert');</script>");
只是把你的代码,而不是alert
。您可能能够从那里调用该函数,但我还没有测试过。
