Javascript serializeObject function

[code] $.fn.serializeObject = function() { var o = {}; var a = this.serializeArray(); $.each(a, function() { if (o[this.name] !== undefined) { if (!o[this.name].push) { o[this.name] = [o[this.name]]; } o[this.name].push(this.value || ''); } else { o[this.name] = this.value || ''; } }); return o; }; [/code]

Java vs Javascript

Here are some differences between the two languages: Java is a statically typed language; JavaScript is dynamic. Java is class-based; JavaScript is prototype-based. Java constructors are special functions that can only be called at object creation; JavaScript "constructors" are just standard functions. Java requires all non-block statements to end with a semicolon; JavaScript inserts semicolons at the ends of certain lines. Java uses block-based scoping; JavaScript uses function-based scoping. Java has an implicit this scope for non-static methods, and implicit class scope; JavaScript has implicit global scope. Here are some features that I think are particular strengths of JavaScript: JavaScript supports closures; Java can simulate sort-of "closures" using anonymous classes. (Real closures may be supported in a future version of Java.) All JavaScript functions are variadic; Java functions are only variadic if explicitly marked. JavaScript prototypes can be redefined at runtime, and has immediate effect for all referring objects. Java classes cannot be redefined in a way that affects any existing object instances. JavaScript allows methods in an object to be redefined independently of its prototype (think eigenclasses in Ruby, but on steroids); methods in a Java object are tied to its class, and cannot be redefined at runtime.
