Ivar Referencing elements in Visualforce
Hi everybody.
I have been messing around with trying something and am not sure where I am doing this wrong, and was hoping someone might be able to point me in the right direction.
My very short visualforce code is included below. What I am trying to do is to create a visualforce page that contains an iframe that points to a salesforce dashboard. The page then also contains a small javascript segment that I want to eventually use to periodically refresh the dashboard presumably by firing off the click event on the dashboard's refresh button. I haven't created the periodical timeout loop, as I can't even reference the button.
My problem is that I am not able to reference the refresh button. I have tried many variations but I never seem to be able to find that button. Please if someone has an idea I would really appreciate a hint :)
Maybe I am using the wrong technology to reference the object, maybe I got the id wrong, at any rate, any help will be greatly appreciated :)
<apex:page sidebar="false" showHeader="false"> <div id="test">myText</div> <iframe id="box" src="https://emea.salesforce.com/01Z200000000kFc" width="100%" height="1000" /> <script language="javascript"> document.getElementById("box").document.getElementById("{!$Component.refreshButton}").click(); </script> </apex:page>
I think you are hitting the browser's cross site scripting security. This effectively stops javascript accessing pages/windows/frames from other domains. As your visualforce page is served from a different domain to ema.salesforce.com, you can't access the details.
Hmm... that is a good point bob_buzzard. Any ideas how I can do this without running into that?
I've been playing around with javascript in a sidebar component that clicks various things. The problem is that the sidebar doesn't get displayed for dashboards :(
Hmm... makes me wonder. Now we can add visualforce components directly to dashboards. Would you think cross-site scripting restrictions would still apply if I made a visualforce page specifically to click the button and added that as a component to a dashboard?
I think it would, as it would still come from the visualforce server rather than emea.salesforce.com, as the rest of the dashboard.
In my opinion, there is a syntax problem in the javascript code :
document.getElementById("box").document.getElementById("{!$Component.refreshButton}").click();
It seems that you have used 'document' twice in your code.
Try using the below mentioned code :
window.parent.parent.document.getElementById("{!$Component.refreshButton}").click();
Hope this helps.
