Trigger image onload using javascript or jquery -


my situation need check size of image using javascript , execute piece of code depending on width.here code

        var width, height;         var img = new image();         img.src = "pool.jpg";         img.onload = function () {             width = this.width;             height = this.height;             console.log(width);         }         console.log(width);          if (width > 0) {             console.log('in condition check');             //some code executed         }         //some other code executed cannot put in onload portion

the issue img.onload portion works after below code has finished execution.is there way trigger img.onload function , go in synchronous way of code execution.

no, can't make code wait until external task (usually involving server) has finished execution.

you have put code in callback (or in function called callback) :

   img.onload = function () {         width = this.width;         height = this.height;         console.log(width);         if (width > 0) {            console.log('in condition check');            //some code executed         }     }

to build javascript applications, must learn deal event-based programming, of code act upon events, them user actions or asynchronous task completions.

(technically there way don't use it)

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!
