title: How can I change the text in just a part of my string with javascript?
body: <p>I have a javascript string that contains the following:</p>
  
  <pre><code>data-href="/Admin/Edit?pk=0001I&amp;amp;rk=50050055"
  </code></pre>
  
  <p>How can I change this string so the value of rk is changed to a value held in the string newRowKey? Not sure if it helps but the data format always looks like this with the rk followed by an = and then terminated with the "</p>
