1) How to set `HTML` to already created panel or any other Element?
I am a beginner. I tried the below to set some content inside the HTML
var clickedElement = Ext.getCmp('id').el.child('>');
The above is working fine but the problem is that as the panel has many div's inside it.. the above approach is erasing those inside html (i.e div's).
I saw through Chrome that the panel has three nested div's. So, if I want to add HTML to it then I need to give something like below:
var clickedElement = Ext.getCmp('id').el.child('>').child('>'); //two times child
When I tried the above approach, I am successfully adding the html content and also the div's doesn't remove. Here the problem is that, I can't see the added content (maybe because of some default stylings, I can see the content is being added in Chrome console though.)
I am just asking whether there is any efficient way of adding HTML to the panel. In my opinion, this should be very easy approach which I am complexing here.
2) How to check whether a Element has a particular child ?
Suppose, for example, If I add a extjs Button as a child into my panel while creating it. (which I can do). How to check whether the panel has the particular element (i.e button here)?
Before asking here, I searched alot and found somewhat relative but not helpful link to my problem.
