JavaScript passing coordinates from one function to another -


i having issues passing 2 coordinates 1 function another. don't know javascript, seems correct. please let me know error?

     <head>       <script>        var zoom = 12; // 18 mobile phones because geolocation more accurate          function init() {          // don't bother if web browser doesn't support cross-document messaging          if (window.postmessage) {            if (navigator && navigator.geolocation) {              try {                navigator.geolocation.getcurrentposition(function(ppos) {                send(ppos.coords.latitude, ppos.coords.longitude);              }, function() {});              } catch (e) {}            } else if (google && google.gears) {              // relevant if targeting mobile phones (some of may have google gears)              try {                var geoloc = google.gears.factory.create("beta.geolocation");                geoloc.getcurrentposition(function(ppos) {                send(ppos.latitude, ppos.longitude);              }, function() {});              } catch (e) {}            }          }        }         function send(plat, plng) {          var myiframe = document.getelementbyid("myiframe").contentwindow;          // third parameter, zoom, optional          myiframe.postmessage(plat + "," + plng + "," + zoom, "http://www.qib.la");        }         window.onload=init;       </script>      </head>       <body>       <iframe id="myiframe" src="http://www.qib.la/embed/" width="400" height="400">         check prayer direction towards ka'ba in makkah @         <a href="http://www.qib.la/">qibla direction</a>.       </iframe>  <script type="text/javascript" src="http://praytimes.org/code/v2/js/praytimes.js"></script>  <br> <p align="center">waterloo, on, canada<p> <div align="center" id="table"></div>  <script type="text/javascript">      var date = new date(); // today     var times = praytimes.gettimes(date, plat + "," + plng, -5);     var list = ['fajr', 'sunrise', 'dhuhr', 'asr', 'maghrib', 'isha', 'midnight'];      var html = '<table id="timetable">';     html += '<tr><th colspan="2">'+ date.tolocaledatestring()+ '</th></tr>';     for(var in list)  {         html += '<tr><td>'+ list[i]+ '</td>';         html += '<td>'+ times[list[i].tolowercase()]+ '</td></tr>';     }     html += '</table>';     document.getelementbyid('table').innerhtml = html;  </script>        </body>

is possible return value asynchronous function? how use callback here?

you have syntax error in code:

var times = praytimes.gettimes(date, + b + ',' + c + , -5);

you have "+" , comma following it. i'm not sure intent code was, causing not run.

perhaps intended follow pattern of appending commas strings?

var times = praytimes.gettimes(date + ',' + b + ',' + c + ',' + -5);

or perhaps -5 meant separate argument?

var times = praytimes.gettimes(date, b + ',' + c, -5);

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!
