How do I pass a url parameter through javascript to html

Former Member — Tue, 16 Oct 2007 20:06:18 GMT

Hi everyone,

Does anyone have knowledge of how to pass a URL parameter to a javascript block? For example, I have a URL parameter called "Machine" in the URL below:

http://xmiidevvs/Illuminator/xmiitest/Hamel.irpt?Machine=1

When I try to reference this parameters value in the javascript code, the results are a blank screen (errors out).

Please see my javascript below:



<!--
var Node
Node = {Machine}*2+9   //This does not Work!!!!!/////

document.write("<APPLET NAME='{Machine} Chart' CODEBASE='/Illuminator/Classes'  CODE='iChart' ARCHIVE='illum8.zip' WIDTH='640' HEIGHT='400'   MAYSCRIPT>")
document.write("<PARAM NAME='QueryTemplate'     VALUE='iHistorian/Minutes/TurnMinutesTagname'>")
document.write("<PARAM NAME='DisplayTemplate'   VALUE='iHistorian/Minutes/AllTurnMinutes'>")
document.write("<PARAM NAME='ChartType'         VALUE='Bar'>")
document.write("<PARAM NAME='Title'             VALUE='{Machine}'>")
document.write("<PARAM NAME='Tagname.1' VALUE='OPCSERVER.USBtoCAN.Node " + Node + ".AmberMinutes'>")
document.write("</APPLET>")
//-->

Thanks to all!

Mike

Hi Mike,

Here's a function to get the value of the 'Machine' url param.


function getMachine()
{
   var m = window.location.search.match(/Machine=(w+)&?/);	 
   return m[1];
}

So you can do:


var machine = getMachine();
