Source: Internet

I would like to implement the pre-replacement or replace some of the content of the Web page source , such as bad words, links, pictures or something.

Before loading the Web page rendering, replace, replace and then display to the user, instead of loading and then replace, is there any relevant API can be implemented, or there is no similar function of the extension?

You can do this by developing a chrome plugin
Plug-ins can listen to the loading process of the content of the page, and after the completion of the DOM loading, execute the JS script, replace the contents of it.
A similar plugin has been developed to display the traffic data on each clickable location on the page
