*Update: * Please take a note of @mathoiland’s answer, “It looks like Fancybox 2 deprecated the onClosed callback. It now uses afterClose.” if you are using FancyBox 2.x Pass the onClosed option to the fancybox function. i.e: $(“<YOUR-SELECTOR>”).fancybox({ onClosed: function() { $(‘#sub_cont’).hide(250, function() { $(‘#IDsearchform input’).val(”); }); }) });
std::function<int(int)> bar = std::bind(foo, 2, std::placeholders::_1);
proxy came first and you should likely favor bind as it is a standard. The way they are called varies slightly (due to being attached to Function.prototype vs just being a function) but their behavior is the same. There is a pretty good post here: jQuery.proxy() usage, that ends with that advice.
To figure out the problem let separate statements: auto f = bind(&TestA::testa, &testA, _1, _2); // OK test.setCallback(f); // <<— Error is here setCallback needs to know type of T and it can’t deduce it from f, so give it a type test.setCallback<TYPE>(f); // TYPE: int, float, a class, …
Try this: $(‘.initiator’).on(‘mouseenter mouseleave’, function(e) { $(‘.receiver’).trigger(e.type); }) It will apply the same triggers for the receiver as the initiator receives for both mouseenter and mouseleave. Note that: .hover(over, out) is just a high-level variant of: .on(‘mouseenter’, over).on(‘mouseleave’, out) so using that information you can be more precise when binding and triggering mouse events.

It is usually used when you want to pass a function to an event handler or other async callback. call and apply will call a function immediately letting you specify both the value of this and any arguments the function … Read more
Closures (or arrow functions, aka lambdas) don’t cause memory leaks Can someone to confirm or infirm if the local variables (here el) can’t be cleared by the garbage collector? Or, are modern browsers capable to detect they are unused in the closure? Yes, modern JavaScript engines are able to detect variables from parent scopes that … Read more
To differentiate between scroll up/down in jQuery, you could use: var mousewheelevt = (/Firefox/i.test(navigator.userAgent)) ? “DOMMouseScroll” : “mousewheel” //FF doesn’t recognize mousewheel as of FF3.x $(‘#yourDiv’).bind(mousewheelevt, function(e){ var evt = window.event || e //equalize event object evt = evt.originalEvent ? evt.originalEvent : evt; //convert to originalEvent if possible var delta = evt.detail ? evt.detail*(-40) : … Read more
Once you bound an object to a function with bind, you cannot override it. It’s clearly written in the specs, as you can see in MDN documentation: “The bind() function creates a new function (a bound function) with the same function body (internal call property in ECMAScript 5 terms) as the function it is being … Read more
