title: How to combine javascript into html / ASP.Net in visual web developer?
body: <p>I want to create scripts, and then call them from the html code or the ASP.Net codebehind. How do I do that?</p>
  
  <p>This is probably very simple, but Googling hasn't helped.</p>
  
  <p>For example: I want an <code>ImageButton</code> to have an <code>onmouseover="this.src='...'"</code>. But I want the script to be separate instead of inline.</p>
