how to extract images from web page given a URL?

**Marcmc** · 05-10-2012 11:49 AM

I would like to submit a url and extract the images of this web page submitted. How to do this using javascript? If anyone knows I ask that you create a basic script that I can understand.

Thanks,

it's easy with yql:

Code:

function addScript(u){var sc2=document.createElement('script'); sc2.src=u;
  return document.getElementsByTagName('*')[1].appendChild(sc2);
}



function grabImgs(url, cb){
 var url="http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D%22"+
   encodeURIComponent(url)+
   "%22%20and%0A%20%20%20%20%20%20xpath%3D'%2F%2Fimg'&format=json&callback="+
   ( (cb && cb.name) || cb ||"console.log");

 return  addScript(url);

}

function myCB(data){
  alert(JSON.stringify(   data.query.results.img    ,null,"\t"))
}

//demo
grabImgs("http://www.webdeveloper.com/forum/showthread.php?t=260425", myCB)
