javascript - Making a div fixed at the top of the page -


i have div want move such stuck top of page. let's cannot use position: fixed;

i used $(document).scroll(function(){}) move div scrolling. makes site extremely slow after 10 seconds of scrolling.

my current solution use settimeout() prevent multiple calls. however, causes delay, , div sticks top of page once have stopped scrolling.

is there way continuous smooth moving of div without killing speed?

edit: have following code:

<div id="outerdiv">    <div class="div">       <div class="fixed"></div>       <div class="otherdivs"></div>    </div>    <div class="div">       <div class="fixed"></div>       <div class="otherdivs"></div>    </div> </div>

so .outerdiv has fixed width, , there many .div, such outerdiv has overflow-x: scroll. if use position: fixed on .fixed, not show properly. want each .div column, heading of each column move down

how using 2 different divs. 1 containing fixed content, , 1 containing content should scrollable?

so don't scroll within document within second div?

or... use position:fixed

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!
