clickCallback gets called without a click

[hackingbeauty]

Hello,

I noticed that when react-paginate first gets displayed on a page, it automatically calls the clickCallback handler.

I don't want it to do this. I just want the clickCallback handler called when a page number is clicked.

Am I doing something wrong?

Hello @hackingbeauty,

Indeed, when react-paginate first gets displayed on a page, it automatically calls the clickCallback handler. That's because the clickCallback function is supposed to be the place where you load the content you want to display on a particular page.

As you can initialize the component to display the page of your choice (page 6 for example), it will call the clickCallback at first in order to load the content of page 6.

I hope this helps.

the first data has been fetched, then the callback will fetch duplicated data again.

i don't think automatically calls the clickCallback is good.

Having issues because of this too.
Data is loaded from other method.
onClick handles a pushState to a new url with the new page number.

Being called on mount causes me a loop.

[donperi]

A solution could be to add another props like onLoad/onMount if is needed to call the handler when component is loaded.

Might this be causing an issue where my initial page is linked to [2], where as [1] links to a non existent page-0 ? I created this ticket btw: #104

One thing i just noticed is that the demo provided on this repo doesn't call the 'clickCallback' on load.

Looks like if you use initialSelected it will invoke the click callback on load but if you use forceSelected it will not.

@terencechow spot on, seems to be working on my end using forceSelected. The click callback is no longer being invoked on render.

[AdeleD]

For your information, since react-paginate 3.0.0, the clickCallback (=onPageChange) isn't called anymore during initialization.

@AdeleD I can see here that it is still being called.
Would you be open to PR where I add bool flag whether to call it or not on initial render?

[AdeleD]

Yes the callback is still called because: #116
If you don't want the callback being called during initialization, don't pass prop initialPage when you initialize the component.

<ReactPaginate previousLabel={"previous"}
               nextLabel={"next"}
               initialPage={1} // Remove this line
               pageCount={this.state.pageCount}
               onPageChange={this.handlePageClick} />

Is it OK for you this way?

[mskec]

By removing that line, callback will not be called. This works if you always have initialPage={1}, but won't work if you need to change initial page.

[AdeleD]

Yes indeed. So, you're right, adding a boolean flag to change this behaviour if needed may be a good idea.
