I had a similar problem.
I included a piece of Javascript in the main layout which allows pages
to register
script to be run when onload is invoked, then any page in the layout can
add things:
<html>
<head>
<script language="JavaScript">
var onLoadExpressions = new Array();
var onUnLoadExpressions = new Array();
function addOnLoadExpression(expr, checkForDuplicates)
{
if (checkForDuplicates && findOnLoadExpression(expr))
{
return;
}
var newExprs = new Array(onLoadExpressions.length + 1);
var i;
for (i=0; i<onLoadExpressions.length; i++)
{
newExprs[i] = onLoadExpressions[i];
}
newExprs[onLoadExpressions.length] = expr;
onLoadExpressions = newExprs;
}
function addOnUnLoadExpression(expr, checkForDuplicates)
{
if (checkForDuplicates && findOnUnLoadExpression(expr))
{
return;
}
var newExprs = new Array(onUnLoadExpressions.length + 1);
var i;
for (i=0; i<onUnLoadExpressions.length; i++)
{
newExprs[i] = onUnLoadExpressions[i];
}
newExprs[onUnLoadExpressions.length] = expr;
onUnLoadExpressions = newExprs;
}
function findOnLoadExpression(expr)
{
var exprFound = false;
var i;
for (i=0; i<onLoadExpressions.length; i++)
{
if (expr == onLoadExpressions[i])
{
exprFound = true;
}
}
return exprFound;
}
function findOnUnLoadExpression(expr)
{
var exprFound = false;
var i;
for (i=0; i<onUnLoadExpressions.length; i++)
{
if (expr == onUnLoadExpressions[i])
{
exprFound = true;
}
}
return exprFound;
}
function documentLoaded()
{
var i;
for (i=0; i<onLoadExpressions.length; i++)
{
eval(onLoadExpressions[i]);
}
}
function documentUnLoaded()
{
var i;
for (i=0; i<onUnLoadExpressions.length; i++)
{
eval(onUnLoadExpressions[i]);
}
}
</script>
</head>
<body onload="documentLoaded();" onunload="documentUnLoaded();">
</body>
</html>
then in your jsp just use:
<script>
addOnLoadExpression('alert("hello");', false);
</script>
