[Vtigercrm-developers] How to extend feature such as Global Search without core modifications ?

[Preexo]

Oh, but If I define it like this, I can see bar when loading the page and foo
when actually searching something... Is this the right way then to overwrite
a function of an existing class?

Vtiger_Header_Js("Vtiger_Header_Js",{},{ 
    basicSearch : function() { 
	console.debug("bar");
    }, 
}); 
Vtiger_BasicSearch_Js("Vtiger_BasicSearch_Js",{},{ 
	search : function(value) {
		console.debug("foooo");
	},    
});


Thanks for support and help again! Best regards
