I want to implement a toolbar (probably with javascript) that will be displayed on the top of any site. So, suppose I will enter to google.com, I want on top of the the main page to display my toolbar. Do you have any idea of how this can be implemented to work on any browser ?
I’m a newbie in this domain. Can you give me an example of how this can be done ?
Thanks
Unless you plan to package this as a browser extension/plugin (eg, for Chrome, Firefox or Safari), you will no doubt run into cross-site scripting security issues if you’re trying to run javascript on another domain’s page (unless you’re planning to have other site owners voluntarily include your script in their pages, too; in this case, ignore this answer).
You could always go old-school and create a top ‘frame,’ running the third-party content within a bottom frame, but the top navbar would be unable to interact with this content, regardless.
