jQuery test for whether an object has a method?

Question

Is it possible to test whether a jQuery object has a particular method? I\'ve been looking, but so far without success. Thanks!

Answer 1

//Simple function that will tell if the function is defined or not
function is_function(func) {
    return typeof window[func] !== 'undefined' && $.isFunction(window[func]);
}

//usage

if (is_function("myFunction") {
        alert("myFunction defined");
    } else {
        alert("myFunction not defined");
    }
