title: Javascript replace query string + with a space
body: <p>I'm grabbing the query string parameters and trying to do this: </p>
  
  <pre><code>var hello = unescape(helloQueryString); 
  </code></pre>
  
  <p>and it returns:</p>
  
  <pre><code>this+is+the+string
  </code></pre>
  
  <p>instead of:</p>
  
  <pre><code>this is the string
  </code></pre>
  
  <p>Works great if %20's were in there, but it's +'s. Any way to decode these properly so they + signs move to be spaces?</p>
  
  <p>Thanks.</p>
