Hi every one,
I need to poll an image using javascript and need to perform an action once
the image is found at its position. This is the code I have written for this
task.
/*----Image handling script starts here----*/
var beacon = new Image();
beacon.onload = function() {
console.log('Image found');
console.log(this.width,this.height);
window.clearInterval(timer);
};
beacon.onerror = function(){
console.log('Image not found');
}
var timer = window.setInterval(function(){
console.log('sending the request again');
beacon.src = "http://www.google.co.in/logos/2010/lennon10-hp.gif";;
},2000);
/*----Image handling script ends here----*/
Problem is that, after one GET request, the response gets cached and
requests don't get sent everytime I set src. If you examine NET tab, it
sends request only on first src set and caches the response.
I need to send a fresh request for image every time my code sets the src.
Any workarounds?
-Regards
