There are many ways you could go to the parent CRM window, but this is what I prefer. At first, I followed the SDK example, but then I invented my own. You could follow the SDK if you will?
Even though it is a little JavaScript but the challenge here is to know if the parent window is the one YOU are looking for?
So here is a little chunk of code that confirms you the Parent Window.
if(window.opener) //checks if current window has a parent window
{
var oParentForm = window.opener.parent.document.getElementById('crmForm');
if(oParentForm) //This confirms if the parent window is a CRM form
{
// Now try to access a field in the parent form
// like name attribute in Account entity
if(oParentForm.all.name) //This ensures you have reached the form you're looking for
{
// Proceed with your code
}
}
}
There could be other methods too, like checking the Object Type Code of the parent form instead of the 'name' field.
More ideas are welcome, don't hesitate, but share.
