title: stop working of function from another function
body: <p>I have two functions</p>
  
  <pre><code>function1()
  {
       //...
  }
  </code></pre>
  
  <p>in <code>function1</code> i make ajax requests and load an image</p>
  
  <p>there is another function - <code>function2</code> where i call <code>function1</code> to load an image.</p>
  
  <p>now, what is the question. </p>
  
  <p>How can i stop propagation of <code>function1</code> before i will call it again in <code>function2</code>?</p>
  
  <pre><code>function2()
      {
          // ...
          // how stop old propogation of function1 here?
          function1(); //call function1 again
  
      }
  </code></pre>
  
  <p>Thanks</p>
