Not getting a variable value?


I am not getting the value of the variable of "img_srt" in load function, can any body helps me?

$(document).ready(function() { Get_var(); }) var img_srt='<div>address</div>'; function Get_var() { $("<img />").attr("src","http://www.google.com/intl/en_ALL/images/logo.gif") .load(function() { if (this.height > 0) { img_srt += "<div><img src='http://www.google.com/intl/en_ALL/images/logo.gif'/></div>"; } }) alert(img_srt); }


The function which sets img_srt is called asynchronously. That is, it may be executed before or after your alert statement. Likely after, as you're having this problem.

Try something like this:

$('<img/>') .attr('src', 'http://www.google.com/intl/en_ALL/images/logo.gif') .load(function() { var imageLoaded = this.height > 0; if(imageLoaded) { $(this).appendTo('#myDiv'); } else { $('<p/>').text('Unable to load image').appendTo('#myDiv'); } });
