    Question Multiple Ext.Button handlers

    Multiple Ext.Button handlers


    is there a way to put multiple handlers on a button, so it starts multiple functions at once??
    something like, open all button??

    Code:
    Ext.onReady(function() {
    
        var myButtonAll = new Ext.Button({
    
            text       : "OPEN ALL",
            handler    : varname, varname...???
            renderTo   : "buttons",
            scale      : "large",
            iconCls    : "button_two",
            width      : 100,
            height     : 100,
     
        
        });
            
    
    });

    Since the "handler" config option just assigns the function to the click event of the button... you can add multiple click events to your button like this:

    Code:
    Ext.onReady(function() {
        var myButtonAll = new Ext.Button({
            text       : "OPEN ALL",
            handler    : varname, varname...???
            renderTo   : "buttons",
            scale      : "large",
            iconCls    : "button_two",
            width      : 100,
            height     : 100,
        });
        myButtonAll.on('click', handler1);
        myButtonAll.on('click', handler2);
        myButtonAll.on('click', handler3);
        myButtonAll.on('click', handler4);
    });
    Or you can wrap all of them in an anonymous function like this:

    Code:
    Ext.onReady(function() {
        var myButtonAll = new Ext.Button({
            text       : "OPEN ALL",
            handler    : function() {
                            handler1.apply(this, arguments);
                            handler2.apply(this, arguments);
                            handler3.apply(this, arguments);
                            handler4.apply(this, arguments);
                        }
            renderTo   : "buttons",
            scale      : "large",
            iconCls    : "button_two",
            width      : 100,
            height     : 100,
        });
    });
    And the handlers should have the signature of the button click handler, for example:

    Code:
    handler1 = function(button, event) {...}

    You don't need to be an anonymous function. Adding multiple event listeners will affect performance. Best way to do it is have a wrapping function.
