Node.lastChild-1 for max page number. (next link is last)

   // Access single unordered list: [0] index  
    var unorderedList = document.getElementsByTagName('ul')[0];  
      
    // Create Node list of all list items within the UL:  
    var allListItems = unorderedList.getElementsByTagName('li');  
      
    // Now, we can loop through each list item using a FOR loop:  
    for (var i = 0, length = allListItems.length; i < length; i++) {  
        // Extract text node within and alert its content:  
        alert( allListItems[i].firstChild.data );  
    }
