I have a problem with calling function passed as parameter in class
definition. I get error when i call fun(). How can i correct this ?
var Slider = Class.create({
initialize: function (elContainer) {
this.elContainer = elContainer;
if($(this.elContainer).getStyle('left') == '0px') {
this.minimize(this.doit);
} else {
this.doit();
}
},
minimize: function(fun) {
new Effect.Morph(this.elContainer, {
style: 'left: 940px;',
duration: 0.3,
afterFinish: function() {
$(this.elContainer).setStyle({
left: '-940px'
});
if(fun != null) {
fun(); <--- !!!!!!!!! ERROR !!!!!!!!!!
}
}.bind(this)
});
},
maximize: function() {
$(this.elContainer).show();
new Effect.Morph(this.elContainer, {
style: 'left: 0px;',
duration: 0.5
});
},
doit: function () {
}
});
(i pasted in: http://pastie.org/391563 to view better)
By the way - this works fine:
function foo(){
alert('foo');
}
function bar(fn){
if(fn != null) {
fn();
} else {
alert('bar');
}
}
bar(foo); // alerts 'foo'
bar(); // alerts 'bar'
