JavaScript function and return


The result page in jsfiddle renders html.

The Javascript function 'console.log()' outputs information to the browser console, not to the Document Object Model (dom).

You can view javascript console output in any browser console, I like to use Chrome Web Tools, or you can build your own HTML to see the results

Rest assured, the function you wrote works, it just doesn't represent itself in the results part of jsfiddle.

Edit: formatting

Edit 2: If you just want the confidence your Javascript function is working, without other technical information, change console.log(number) to alert(number)

Unable to return NULL in a function that expects an integer return type
If the return type is int, you can't return a NULL. To show an error, you could instead return a special value like zero or -1, if you check for that value in any calling function. Lots of functions return nonnegative numbers on success, or -1 on error. NULL cannot be stored in an int variable, unlike in SQL, for example. If you ignore the warning and return NULL anyway, then NULL will be casted

Return value for parent function (nested); Waiting for asynchronous function
You might find it more useful to write a constructor that returns a "promisified Image", ie an instance of window.Image with a custom .setSrc() method that returns a promise. Something like this (untested) should do it : function PromisifiedImg() { var img = new Image(); img.setSrc = function(src, limits) { var dfrd = $.Deferred(); img.onload = function() { i
