[SalesForce] How to pass variables from Iframe to VF page URL? I’m displaying a vfpage in sidebar as homepage component

I have a visualforce page and a controller for it, already written. My requirement is to show the same page as one of the homepage components in the left sidebar, I did that by calling through an iframe, till now all working fine. When any page will get loaded, I want the url of the page not of the visualforce page which I have created. eg.'https://na12.salesforce.com/001/o' or 'https://na12.salesforce.com/home/home.jsp' but not the one like '/apex/mypagename'.

How to achieve this ?

<iframe src="/apex/HomePageComponent?core.apexpages.devmode.url=1" id="showskill" frameborder="0" height="100px" width="180px"> </iframe>

this is my iframe code, I want something like where I can pass a string, appending it to src probably this way, '/apex/mypage?id='+var

I managed to find the answer with the help of one of my friends, it was simple but really hard to find.

<iframe src="/apex/HomePageComponent?core.apexpages.devmode.url=1" id="showskill" frameborder="0" height="100px" width="180px"> </iframe>

I was doing the same stuff earlier also.. just found out something called Frame[0].location which helped me achieve the desired reqmnt.

<script> 
    var location = window.location;  
    var static_location = "/apexHomePageComponent?core.apexpages.devmode.url=1&src="; 
    var abs_url = static_location + location; 
    frame[0].location = abs_url; 
</script>

Now, from the Vf page's controller i can fetch the value of 'src' quite easily

Thank you so much Vishal for this. :)

If your page is using a controller or extension (if it's not, just create an extension) then you should be able to get the URL you're after using the referer header for the Visualforce page.

Use the following method to get the URL:

public String getReferer()
{
    return ApexPages.currentPage().getHeaders().get('referer');
}

Then you can just get this in your page using:

<apex:outputText value="{!Referer}"/>

Messy. Real shame that stuff like {!$User.Username}, {!$UserRole.Name} doesn't work in the HTML components.

If you have to scrape - try to do it by user id, not by name of the user. I've recently fixed an interesting bug where one trigger didn't work for Hungarian users - trigger was looking for FirstName LastName and Hungarian locale flips the order like in Asian languages ;)

There's one javascript variable you might reuse without all the hassle of traversing DOM:

var id = UserContext.userId;
console.log(id);

Combine with an array with user Ids and you're getting somewhere. I'd be tempted to explore cookies route too (kind of user preferences) but that means you'd have to assign them somehow in pure JS (cookie served from Visualforce will come from different domain) and you'd need to think how to set cookie if null before relying on its' value so it works ok when new user / new browser is used...

Is AJAX really banned? One query for example to test Group membership (or flag on User), set the cookie and subsequently rely only on the cookie could work and be fairly OK in maintenance.

If you can live with having ugly placeholders in the sidebar use <apex:page rendered="false">. Put a boolean condition there (if your page has a controller it can be as complex as you need) and on the home page the iframe will still be displayed, just with blank content.
