WordPress.com – How to Add Post History to Your Blog

JavaScript is not allowed on wordpress.com blogs due to security reasons. This means that the following will not work (among others): <script> tags; javascript: links; and events such as onclick.

In fact, that's the reason I switched from wordpress.com to blogger.com. Your only Wordpress option is to either host it yourself, or find some hosting solution that allows JavaScript.

If you decide to host it yourself, JavaScript will work out of the box (tested on latest version only), and you can find more information here.

If for some reason you cannot use JavaScript with your hosting, you could try to see if it supports the Inline JavaScript Plugin [via], which will enable JavaScript. Wordpress.com does not support this plugin.

Publishing

Once you're done creating and editing your spreadsheet, you can publish it to a webpage. >Just click the Share drop-down menu on the top right and choose Publish as a webpage. Then, click Publish now.

Then, everyone you choose can access your spreadsheet by entering the URL you send them into their browser's address bar.

Even after you publish a spreadsheet, it won't appear in any search index.

Embedding

After you publish your spreadsheet, you can share it with the world by embedding it (or parts of it) in a website or blog.

Publish your spreadsheet following the steps listed above and a unique URL is generated. Use this URL to embed the spreadsheet on your website or blog. You can also insert a spreadsheet in Google Sites. Just click Edit page > Insert > Spreadsheet from within your site. You'll need to enter the URL of your spreadsheet to embed it.
