javascript - drag and drop not working in firefox -


i have implemented drag , drop functionality in jquery , html5 , working great in chrome stuck in firefox following code alerting id of dropped image appears undefined in firefox following code , please . jsfiddle: http://jsfiddle.net/rajutikale/2r6p8/

view: 

<!-- dragable image -->  <a href="#?w=976" rel="popup1" id="<?=$album['album_id'].'-'.$data->content_id?>" class="poplight album_photos"><img  id="<?=$album['album_id'].'-'.$data->content_id?>" draggable="true" ondragstart="drag(event)" ondragover="allowdrop(event)" alt="" src="<?=$imagepath?>"></a>  <input type="hidden" id="<?='wall'.$data->content_id?>" value="<?=$data->wall_id?>" /> <input type="hidden" id="<?='type'.$data->content_id?>" value="<?=$data->content_type?>" /> <input type="hidden" id="<?='user'.$data->content_id?>" value="<?=$_session['user_type']?>" />  <!-- dropable area --> <div class="" style="z-index: 1; position:fixed; right:124px; top:60px" id="div1" ondrop="drop(event);;" ondragover="allowdrop(event);"> <a href="#"><img id="dropzon_image"src="<?php echo image_path_http?>babbler_btn.jpg" alt="" border="0" style="cursor: pointer; cursor: hand; "/></a>     <div id="overlay" style="display:none;z-index: 2;  position:fixed; right:0px; top:32px; cursor: pointer;border-color: blueviolet;">         <img id="drop_image" src="<?php echo image_path_http?>drop_image.jpg" alt="" border="1" style="cursor: pointer; cursor: hand; " />     </div> </div>

js:

function allowdrop(ev) {     ev.preventdefault(); }  function drag(ev) {     ev.datatransfer.setdata("text", ev.target.id);     $("#div1").find("#overlay").slidedown();     settimeout(function () {         $("#overlay").hide();     }, 4000); }  function drop(ev) {     var id = ev.datatransfer.getdata("text"); /*implimented solution*/     alert(id);     ev.preventdefault();     var action = 'download';     var wall_id = '62';     var stat = 'album';     var cnt = '0';     var user_type = 'r';     var status = do_download(action, wall_id, stat, cnt, user_type);     $("#overlay").hide();     // ev.target.appendchild(document.getelementbyid(data)); }

firefox requires user run datatransfer.setdata function in event.

for jquery users, means following code should resolve issue:

function dragstarthandler(event){    event.originalevent.datatransfer.setdata('text/plain', 'anything');  }

future events on same drag fire expected. can replace setdata arguments more useful data.

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!
