Sample Implementation:
{
match: "http://domain.com/.*" // the url to react to for manga loading
, img: '#image' // css selector to get the page's manga image
, next: '#next_page' // css selector to get the link to the next page
, numpages: '#page_select' // css selector to get the number of pages. elements like (select, span, etc)
, curpage: '#page_select' // css selector to get the current page. usually the same as numPages if it's a select element
, nextchap: '#next_chap' // css selector to get the link to the next chapter
, prevchap: '#prev_chap' // same as above except for previous
, wait: 3000 // how many ms to wait before auto loading (to wait for elements to load)
Any of the CSS selectors can be functions instead that return the desired value.
}
