JavaScript ExtJS - How to automatically scroll to a form field?

I need to scroll to a form field (a displayfield actually) automatically. Since the field is dynamic, sometimes it is already shown in the rendered area of page, sometimes it is not.

How can I do this using ExtJS 4.x?

Answer:1

Use scrollTo function of Ext dom element. Reference

scrollTo( side, value, [animate] ) -> Scrolls this element the specified scroll point.

Parameters

  • side : String (Either "left" for scrollLeft values or "top" for scrollTop values.)
  • value : Number(The new scroll value)
  • animate : Boolean/Object (optional) (true for the default animation or a standard Element animation config object)

Add following lines of code to the form panel.

 listeners:{
        afterrender: function(){            
            this.body.el.scrollTo('top',200,true);
        }
    },
