title: Clear text field value in JQuery
body: <p>I understand this is an easy question but for some reason this just isn't working for me.  I have a function that is triggered everytime a drop down menu is changed.  Here is the relevant code that is suppose to grab the current value of the text field, if a value exists, clear it that is contained within the .change function:</p>
  
  <pre><code>var doc_val_check = $('#doc_title').attr("value");
      if (doc_val_check.length &gt; 0) {
          doc_val_check == "";
      }
  </code></pre>
  
  <p>I feel like I am missing something very simple.</p>
