Extjs 4 How to get id of parent Component?

Question

I have multiple fieldset. And have Button inside each fieldset in Extjs 4. I want to get fieldset id on the button click event, so that i can know from which fieldse

Answer 1

I've implemented handler properly.

{
    xtype:'fieldset',
    id:'fs1',
    items:[{
        xtype:'button',
        id:'b1',
        handler:function(btn){
            // Retrieve fieldset. 
            var fieldset = btn.up('fieldset');
            // Retrieve Id of fieldset.
            var fieldsetId = fieldset.getId();
        }
    }]
}

In that case try this:

button.up("[xtype='fieldset']")
