title: Javascript Add Dynamic Input Field
body: <p>I'm not good with Javascript at all, so I come here to seek assistance.</p>
  
  <p>What I have is a form, with a link that says "Add additional URL field". I want it so when a user clicks that, it will populate an additional field underneath the default url field, with a unique input name, such as url_input1, and if they click it again to add another url input, the name of that input would be url_input2, etc.</p>
  
  <p>How can I do this with Javascript?</p>
