如何通过Google Closure Compiler将功能标记为“私有”以重命名？

Question

I have private function createSomething():

function Player(id) {

  /**
   *  Creates stuff
   *  @private
   */
  this.createSomething = function() {
    // do something good
  };
}

and I want to see the renamed function "createSomething()" after compiling the source with Google Closure Compiler. Yes, I know about ADVANCED_OPTIMIZATIONS but it is incompatible with jQuery and other libraries.

Answer 1

The solution is to use a string literal to refer to the property.

function Player(id) {
  /**
   *  @private
   */
  this['createSomething'] = function() {
    // do something good
  };
}

This works because the compiler never renames string literals. But be careful.

You can compile your code with ADVANCED_OPTIMIZATIONS and still have you compatibility with other libraries. You'll need to read about externs and exports in the library documentation:

• http://code.google.com/closure/compiler/docs/limitations.html

Just use without this

function Player(id) {

  /**
   *  Creates stuff
   *  @private
   */
  createSomething = function() {
    // do something good
  };
}
