i trying execute javascript function on page load , postback phone call function in code behind. getting time zone info , trying pass them arguments __dopostback. here have (abbreviated):
in .aspx file
<body onload="getlocaltime()"> .... function getlocaltime(){debugger var d = new date(); var tzoffset = d.gettimezoneoffset(); var hfoffset = document.getelementbyid('<%=hfoffset.clientid%>'); var hftzname = document.getelementbyid('<%=hftzname.clientid%>'); var tzname = gettimezonename(); hfoffset.value = tzoffset; hftzname.value = tzname; __dopostback('tzsessionvars', tzoffset, tzname); } in code behind's page_load(), if ispostback true:
string starget = request["__eventtarget"]; if (starget.equals("tzsessionvars")) { string sarg = request["__eventargument"]; settzsessionvars(sarg); // parse argument , set session vars } when trace javascript, when hits __dopostback, says:microsoft jscript runtime error: object expected
the parameters tzoffset , tzname ok , have valid values.
you can utilize __eventargument explained in article.
