Private vs Public Javascript Functions -


can please explain difference between these 2 functions?

(function(engine, $, undefined) { //hidden scope     //public function below     engine.init = function() {         console.log("im public");     }      //anonymous functions below     function login() {         console.log("im private");     } })( window.engine = window.engine || {}, jquery );

specifically, i'd know why engine.init() available in console login isn't.

init property of engine object refers function.
can access other property.

login local variable within anonymous, "immediately invoked function expression" (iife); other local variables, name visible within declaring function

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
