Subject [jira] Commented: (TAPESTRY-2364) YSlow Recommendation: Write Scripts at bottom of page
Date Mon, 06 Oct 2008 19:19:44 GMT

    [ https://issues.apache.org/jira/browse/TAPESTRY-2364?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12637184#action_12637184

Davor Hrg commented on TAPESTRY-2364:
-------------------------------------

this is simply untrue.
QUOTE: "Otherwise it is impossible to execute Javascript before the page renders..."

A listener to onload can be added no matter where script tags are.
onload will not be called until all page resources are loaded.

if you use tapestry to add script to the page, the script will be called inside an onload
handler (after all scripts are loaded). 

you can always make content hidden, and show it after parsing it.

> Tapestry is already doing a good job on this, by writing the dynamically generated <script>
block at the bottom of the page, but the external scripts should also be down there.
