How to add a javascript within a iframe's tag ?

I have iframe's tag as below:

<iframe name="booklst" src="BookLst.jsp?acctno=<%= acctno %>&price=<%= price %>"></iframe>

My question is, instead of using a jsp expression tag "price=<%= price %>", could we replace the statement with a javascript statement, within the iframe html tag?

Thanks in advanced.

You cannot replace it with a client-side script expression. You could modify the src attribute from a client-side script block elsewhere in the page but you would have to know or be able to receive the account number and price from somewhere:

Code:

function modifyIframeSrc(IframeName, Src)
{
  var oFrame = document.getElementsByName(IFrameName)[0];
  oFrame.src = Src;
}

function getAccountSrc(AccountNumber, Price)
{
  var sSrc = "BookLst.jsp?acctno=" + AccountNumber + "&price=" + Price;
  return sSrc; 
}

Then somewhere you need to call:

Code:

var sAccountNumber = "=<%= acctno %>";
var sPrice = "=<%= price %>";
modifyIframeSrc("booklst", getAccountSrc(sAccountNumber , sPrice));

or you may have other ways of retrieving the details.
You still may need to force a refresh of the iframe for the new page to show properly.
