If you’re using the trusty CEWP (Content Editor Web Part) to locate the current web part frame on a page you’ll want to consider using the “_WPQ” expression instead of hard coding a number. Using the Internet Explorer Developer toolbar or Firebug toolbar is a great way to locate <DIV> tags and “ID=” attributes with a single click.
However, don’t be tempted to code in the number. As you re-order web parts they will changes. If you add more than one CEWP (export/import) the others will fail. Use a dynamic token for maximum flexibility.
SharePoint’s rendering engine does a search replace on “_WPQ_” to give it the number of that web part on the page. It’s a great way to avoid naming conflicts and a trick I’ve used to apply multiple JQuery driven CEWP on the same page.
