[Zope] Zope and Javascript

Fri Apr 16 02:12:33 EDT 2004

Actually the answer is up to javascript rather than Zope. You just need any
method, i.e. "dynjavascript.js", that queries your sql database according to
passed parameters, and that returns javascript code. Then you generate
"dynparameters" within your page, in order to call a function inside
dynjavascript.js.

<html><head>
<script type="text/javascript"><!-- 
function generatejs(params){
var s = document.createElement("script");
s.type = "text/javascript";
s.src = "dynjavascript.js?" + params;
document.getElementsByTagName("head")[0].appendChild(s);
return null;}
//--></script>
</head>
<body>
<script>
//just a sample, you generate the one you need
var dynparameters="key1=value1&key2=value2"</script>
<a onclick="return
generatejs(dynparameters);function_inside_dynjavascript();">
sample usage</a>
</body>
</html>
