value = row.find('a').html();

value is :  " <img src="http://localhost/Domus/uploadFile/server/php../../../../images/immobili/tmp_kernel/thumbnail/58.jpg"> "

I try with

2.  String.prototype.filename = function (extension) {
3. 
   
4.             var s = this.replace(/\\/g, '/');
5.             s = s.substring(s.lastIndexOf('/') + 1);
6.             return extension ? s.replace(/[?#].+$/, '') : s.split('.')[0];
7. 
   
8.         };
9. nomeCopertina = value.filename();

but nomeCopertina is the name of file without the extension.

how can I fix it?
