Hello

  1. On line #98 (in code below) I specify this "<img draggable=“false” .
    But it is still ‘draggable’
  2. On line #148 I specify "clone.draggable = ‘true’; " .
    But it isn’t ‘draggable’ .
    After running the code and then I download the page , it Shows that the Cloned img is indeed written as “draggable=“true”” .
    So how can I fix things ?
    Thanks for your Help…

The issue seems to be with the draggable property of the img elements not being set correctly. According to the HTML5 specification, the value of the draggable attribute should be either "true" or "false", but in the code the value is being set as a string with curly quotes (“false” and “true”). To fix it, replace the curly quotes with regular double quotes, e.g. draggable="false".

Line #98:

Python:
<img  draggable="false" class="item" id="one"  src="https://vmars.us/Guitar/1-Red-Circle-Transp-32x32.png" >  // 98

Line #148:

PHP:
clone.draggable = true;
