A about the extend question

[hui2008]

Dear all,

monindex = Ext.extend(Ext.Panel,{   
                     myclick:function(value){   
           Ext.getCmp('mdetail').load({url:"action.php",params:{sid:value},scripts:true,scope:this});   
    }   
});   
Ext.reg('mindex',monindex);

I want to use "myclick" like this :

<a href="#" onclick="javascript:myclick('123');">abc</a>
