nextLinkByUrl

If there is no next element, you can use this to generate a href from current url, [0] means RegExp string, [1] means replace string, [2] means selector or xpath of the element which must include, [3] means selector or xpath of the element which must not include, you can use {} to eval simple code.

Example1:

"nextLinkByUrl": [
    "(&page=(\\d+))?$",
    "&page={$2+1}"
]

Create a next link "http://abc.xxx/d?page=2" from URL of current page: "http://abc.xxx/d?page=1"

Example2:

    "(&page=(\\d+))?$",
    "&page={$2+1}",
    ".disable>button"
