Extjs4 ,如何偵測是否點在pop up window 的外面

參考:

我個人是比較喜歡寫在"initComponent"之後的寫法
======================

     initComponent: function () {

        ...

         ...
        
        me.callParent(arguments);

        me.mon(Ext.getBody(), 'click', function(el, e){
            alert('click outside!!');
        }, me, { delegate: '.x-mask' });
    }

=====================
大家加油吧
