how get the value of a script tag

问题

In my page code, there is this script tag:

<script>
  var oid = "182384";
  document.getElementById('container').innerHTML = oGrid;
  oGrid.setShowSid(false);
  oGrid.calcSize();
  setupAllTabs();
  var toolbar = setupMenuButtons("btnbar");

  initForm(toolbar);
</script>

How can I get the value of oid with watir or ruby?

回答1:

browser.script.html will output the code within the <script> tag. For example:

require 'watir'  

browser = Watir::Browser.new
browser.goto("http://www.some_site_with_script.com")
browser.script.html

Then--as @rainkinz indicates--you can extract whatever values you want using regex:

b.script.html.match(/var\soid\s\=\s\"\d+\"/)
