I have tried a lot on searching but could not find a working script for the limitation of the file size using javascript here below is my code but it is not working 

   if ($('#photo').get(0).files.size >1024 ) 
       {

                 alert("Please select pic size less than  1 mb file .");
                 return false;
    }

Where photo is id of input type file

    size is in bytes. you need to divide it by 1024 to get KB and 1024 again to get MB. Ignoring the syntax error your code validates that the file is < 1KB Commented Aug 2, 2018 at 9:44
  • Liam , I have to divide it or multiply ? Commented Aug 2, 2018 at 9:47
  • 1mB = 1,048,576 bytes or you can write 1024 * 1024 Commented Aug 2, 2018 at 9:49
