title: Stop running javaScript file in Google Chrome
body: <p>In my Google Chrome extension it adds a javaScript file or code when the user click on the browser action. 
  ex: </p>
  
  <pre><code>chrome.browserAction.onClicked.addListener(function(tab) {
  chrome.tabs.executeScript(null,
                         {code:"document.body.bgColor='red'"});// or any .js code file
  });
  </code></pre>
  
  <p>how can I remove this JavaScript or the code when user click on a button. 
  Assume that there is a code like below triggered when user click on a button.</p>
  
  <pre><code>chrome.tabs.executeScript(null,
                         {file : "tabcolor.js"});
  </code></pre>
  
  <p>So i want to stop this <code>tabcolor.js</code> execution after User click on the same button. How can I do this ?</p>
  
  <p>Is there any method to <code>stop ExecuteScript</code> ?</p>
