jquery - How to add delay time into line of code on JavaScript -


im trying function when user move cursor on image show preview. im taking src of image fired event , im changing path of different images. 

$('#image').hover(function(){     var src = "";     var elem = $(this);     (var i=2; i<16; i++) {         src = elem.attr('src').split('.');         src[3] = i;          src = src.tostring();     src = src.split(',').join('.');     elem.attr('src', src);     } });

the problem here, when try below, putting delay every preview doesn't work want.

$('#image').hover(function(){     var src = "";     var elem = $(this);     (var i=2; i<16; i++) {         src = elem.attr('src').split('.');         src[3] = i;          src = src.tostring();         src = src.split(',').join('.');         settimeout(function() {             elem.attr('src', src);         }, 800);     } });

how can solve it? i'm working problem +2h

the problem cant use settimeout inside loop.. instead of use setinterval..

 $('#image').hover(function () {     var src = "";     var elem = $(this);     var = 2;     var interval = setinterval(function () {         if (i < 16) {             src = elem.attr('src').split('.');             src[3] = i;             src = src.tostring();             src = src.split(',').join('.');              elem.attr('src', src);             i++;         } else {             = 2;             clearinterval(interval);         }     }, 800); });

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!
