  • JavaScript check if anonymous object has a method

    - by Baddie
    How can I check if an anonymous object that was created as such: var myObj = { prop1: 'no', prop2: function () { return false; } } does indeed have a prop2 defined? prop2 will always be defined as a function, but for some objects it is not required and will not be defined. I tried what was suggested here: http://stackoverflow.com/questions/595766/how-to-determine-if-native-javascript-object-has-a-property-method but I don't think it works for anonymous objects .
