Passing Strings with commas to a javascript method

Hi people,

This is probably a quicky for someone but its wrecking my head - I am trying to pass 2 strings which contain commas to a javascript method within a jsp but it fails as the javascript method thinks that the words in the string before and after the comma are seperate variables

here is what I am trying to do in a simplified form:

 <script type="text/javascript">
function initialize(str1,str2) {
     console.log(str1);
     console.log(str2);
}
</script>
<%
String str1 = "hello, world";
String str2 = "stupid, commas";
%>

<body onload="initialize(<%=str1%>,<%=str2%>)">
<p>&nbsp;</p>
</body>

The error that firebug gives me is :

hello is not defined

Hopefully someone has experienced this before and can point me in the right direction.

Cheers,
Patrick.

Also before someone mentions that I could just escape the commas unfortunately I need the commas in the strings as the strings being passed are being used as googlemaps directions start and end points!

It's not the commas - you're passing in a string that's not in quotes.

initialize(<%=str1%>,<%=str2%>)

turns into

initialize(hello, world, stupid, commas)

You need it to be:

initialize('hello, world', 'stupid, commas');

So you need to do this:

initialize('<%=str1%>','<%=str2%>');

Cheers Eoin ... knew it would be something ridiculously simple!!
