Surprises in JavaScript: blocking double form submission

Anyone can double click to edit the block below. Its content is not necessarily from Sedition·com or reviewed or approved by us. Your chalkboard entry will stay there until someone else does the same or the server cache is reset or expires in a week. Rules: XHTML strict, no styles, no scripts, no <pre/>, no attributes except href for links, 750-ish characters, and, as usual, threats and abuse won’t be tolerated unless they’re very, very funny.

Why would you want to do this? You can put an ad and link for your site there. You can put a “Sedition·sucks” there. It’s above the fold on the top page and it’s all yours until the next visitor comes along.

Why would we want to do this? 1) Free speech is fun. 2) Cross-pollination is fun. 3) A Web 2.0 résumé point is nice when poking the job market with a sharp stick.
