Edit JavaScript blocks of web page... live

Question

I know you can use Firebug in the DOM view to edit JavaScript variables BUT... is there a way I can use (anything else) to edit live JavaScript that is embedded in a HTML page?

Like this kind that is in a .html page:

<script type="text/javascript>
// code here
</script>

Thanks.

Answer 1

bookmarklets

From the Wikipedia entry

A bookmarklet is an applet, a small computer application, stored as the URL of a bookmark in a web browser or as a hyperlink on a web page. The term is a portmanteau of the terms bookmark and applet. Whether bookmarklet utilities are stored as bookmarks or hyperlinks, they are designed to add one-click functionality to a browser or web page. When clicked, a bookmarklet performs some function, one of a wide variety such as a search query or data extraction. Usually the applet is a JavaScript program.

And as a related note _{not trying to spam or anything} I created a bookmarklet generator to help me create bookmarklets easier.

You could use Opera 12. Opera 12 allows editing of inline JS and JS files. After you soft reload the page, your changes will be applied. Right click > Source > Make changes > Apply Changes.
