passing url as parameter in javascript is not calling the function - 


<a href="javascript:void();" onclick="openwindow(2,1,4326,http://www.../images/icon_tree1.gif);">edit asset info</a>

function openwindow not called , see folowing error on console

uncaught syntaxerror: unexpected token : ,

uncaught syntaxerror: unexpected token )

this actual code using 

return "<a href='javascript:void();' onclick='openwindow(" 2 "," + 1 + "," + 4326 + "," + symbolurl + ");'>edit asset info</a>";

url address string, should surround quotes:

... onclick="openwindow(2,1,4326,'http://www.../images/icon_tree1.gif');" ...

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!
