Inject JS __doPostBack is not defined Error

[A_A]

Hello,
I try to inject this to a website to change to the next page but get an error that tells me dopostback is not defined. What does this mean and how can I find a solution?

“__doPostBack(‘ctl00$MainContent$gvwF’,‘Page$7’)”

Do anyone know in what direction I can go to find the answer? I have been trying to figure this out for over a week without any luck.

I couldn’t find a solution to the problem.
The way I found to do it was to open the console in Chrome using shortcuts CRTL+SHIFT+J (and TAB to be able to write) then paste javascript:__doPostBack(‘ctl00$MainContent$gvwF’,‘Page$7’) in the console and send ENTER.

Now I need to find a way to do +1 on the 7 to be able to go trough all pages without making a huge list first. I guess its a loop with a variable or something.
