jslint - In Javascript, under what conditions is it appropriate to only use `this` in constructor functions? -


i found an interesting line of code in jshint's config options.

the comment associated option reads tolerate using in non-constructor function.

i confused. misunderstanding config option?

aren't there lot of cases want use this in non-constructor function? when ever want warned it?

this options used tell jshint function invoked valid this parameter.

for example:

function myrandomfunction() {     alert(this.something); }  myrandomfunction.call(someobject);

if strict mode on, jshint warn myrandomfunction shouldn't using this, since doesn't constructor or member function.
if know called this (eg, callback), can add /*jshint validthis: true */ suppress warning.

c# - Send Image in Json : 400 Bad request -

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!
