title: Remove the previous ajax called result?
body: <p>I am using jquery and I have 2 ajax call function. When I call the first ajax request then
  the result will display at div id="result". Then I call the second ajax and I want it to display at div id="result" as well and replace the previous result which return from first ajax. From my tested, I still able to see the previous result under browser developer tools. </p>
  
  <p>The second question is, if repeatly click will cause memory leak or not?</p>
  
  <pre><code>$.ajax({
    url: "ajax/func1",
    type: "post"
  });
  
  $.ajax({
    url: "ajax/func2",
    type: "post"
  });
  </code></pre>
