Regex to remove and its content in Javascript -

I am trying to remove the script and their content from the HTML body and it has come so far when

  just_text = just_text.replace (/ & lt; \ s * script [^> *] ( * *] | $) / Ig, '');   
 It does not want to work, I still get the content.  
 Can you help me?  
 Thanks   
 
 
 Answers like these questions are always the same: Regular expressions are used Do not Instead, parse HTML, modify the DOM and resear it over HTML if you need it.  
 Example:  
  var container = document.createElement ('div'); Container. Piler html = just_text; // Find and delete script 'elements' var scripts = container.get elementsbignnam ('script'); For (var i = scripts.length; i--;) {script [i] Parent.Node.removeChild (script [i]); } Just_text = container.innerHTML;   
 If you want to delete the  script  tag from the page, then it is basically the same:  
  var scripts = Document .body.getElementsByTagName (such as script '); For (var i = scripts.length; i--;) {script [i] Parent.Node.removeChild (script [i]); }
