title: Stop execution of Javascript function (client side) or tweak it
body: <p>I want to stop the execution of one single line from a site, so that the whole page is read by the browser except that single line. Or the browser may simply skip the execution of that javascript function.</p>
  
  <p>OR</p>
  
  <p>Is there way i can tweak the javascript somehow so that the random number generating function in javascript do not generate random number, but the numbers i want...</p>
  
  <p>I dont have access to the site on which the script is hosted so all this needs to be done client side.</p>
