javascript - How can I toggle a class inside a button on click? -


what's proper way toggle couple classes on click in jquery?

1) html before click:

<button class="btn"><i class="icon-sign-blank"></i> click me!</button>

2) html after click:

<button class="btn btn-success"><i class="icon-check"></i> clicked!</button>

3) html after click: (same beginning)

<button class="btn"><i class="icon-sign-blank"></i> click me!</button>

current jquery:

$('btn').on('click',function(e) {     $('btn > i').removeclass('icon-sign-blank').addclass('icon-check');     $('btn').addclass('btn-success'); });

but works once, not again. what's proper way handle both directions?

you can - should - use toggleclass manage !

$('btn').on('click',function(e) {     $('btn > i').toggleclass('icon-sign-blank icon-check');     $(this).toggleclass('btn-success'); });

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!
