javascript - How to determine how many CSS3 columns are actually being displayed (vs. the specified column-count)? -


i have list of tags in box i've specified having multiple columns:

#tags {   -webkit-columns: 140px 5; }

result:

screenshot - 5 columns

the content of list dynamically generated.

when resize browser window, number of columns collapses. e.g.:

enter image description here

using jquery / js / css / etc., how can determine how many columns being displayed @ given time?

unless specified column width-related properties browsers try fit whole number of columns in content area (between left , right padding of element). (contentwidth + columngap)/(columnwidth + columngap) rounded down give result.

note right padding may set high whole column able fit there - may need adjust computations.

you can directly size of column if have element 100% width inside columns text.

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!
