如何使用javascripts按钮从不同页面获取数据？

Question

I have the following HTML:

 <div class="pagination pagination-centered"> <ul> <li class="active"> <a class="page" data-page="1" href="javascript:void(0)"> 1 </a> </li> <li > <a class="page" data-page="2" href="javascript:void(0)"> 2 </a> </li> <li > <a class="page" data-page="3" href="javascript:void(0)"> 3 </a> </li> <li > <a class="page" data-page="4" href="javascript:void(0)"> 4 </a> </li> <li > <a class="page" data-page="5" href="javascript:void(0)"> 5 </a> </li> <li > <a class="page" data-page="6" href="javascript:void(0)"> 6 </a> </li> <li > <a class="page" data-page="7" href="javascript:void(0)"> 7 </a> </li> <li > <a class="page" data-page="8" href="javascript:void(0)"> 8 </a> </li> <li class="threeDots"> <a class="page" data-page="..." href="javascript:void(0)"> ... </a> </li> <li > <a class="page" data-page="20" href="javascript:void(0)"> 20 </a> </li> </ul> </div> 

When I click in this buttons I go to something like this www.example.com/something?page=X (x = number of the button) I use this:

 Document doc = Jsoup.connect("www.example.com/something?page=5").get(); 

But I get always the first page HTML. How I can "click" or extract information about this pages? I don't know so much about PHP but I think this page use it to change pages.

Edit:
I'm not using javascript. I'm using a java project that extract information from page using html.

Answer 1

It seems you need to dynamically set the page URL argument. If you use jQuery you should be able to have a click event like this:

Document doc = Jsoup.connect("www.example.com/something?page=" + $(this).data('page')).get();

Answer 2

Only a single digit gets changed for every link, you can use for loop with a variable denoting your page number as follows:

for (int i = 1; i <= 8; i++) {
    Document doc = Jsoup.connect("www.example.com/something?page=" + i).get();
              /* Your code for each page*/
        }
