Module Incr_dom.Js_misc

This module has a small collection of helpful bits of javascript that have no other obvious home.

module Rect : sig ... end

val round_float_rect : ?⁠round:(float ‑> int) ‑> float Rect.t ‑> int Rect.t

val viewport_rect : unit ‑> int Rect.t

viewport_rect () gives you the rectangle that corresponds to the size of the entire browser window

val viewport_rect_of_element : Js_of_ocaml.Dom_html.element Js_of_ocaml.Js.t ‑> float Rect.t

viewport_rect_of_element el gives you the bounding box rectangle for a single element

val client_rect : unit ‑> int Rect.t

client_rect () gives you the rectangle that corresponds to the size of the entire browser window without the scroll bars.

val client_rect_of_element : Js_of_ocaml.Dom_html.element Js_of_ocaml.Js.t ‑> float Rect.t

client_rect_of_element el gives you the inner box rectangle for a single element, not including its scroll bars if it has any.

val element_is_in_viewport : Js_of_ocaml.Dom_html.element Js_of_ocaml.Js.t ‑> bool

Returns true iff the element in question is in view.

val scroll : ?⁠id:string ‑> unit ‑> unit

Find an element with an id (default as "keep-in-view"), and, if it exists, scrolls the UI so that that element is in view.

val find_visible_range : length:int ‑> nth_element_id:(int ‑> string) ‑> rows_or_columns ‑> (int * int) option

find_visible_range ~length ~nth_element_id layout is useful to find visible rows or columns of a table. The time cost is O(log(length)). It assumes the rows/columns are non-overlapping and arranged monotonically, though the order doesn't matter. It's assumed that the rows are laid out from 0 to length - 1.

If no row is visible, then None is returned. Otherwise, the inclusive upper and lower bounds of the visible rows are returned.

val get_scroll_container : Js_of_ocaml.Dom.#node Js_of_ocaml.Js.t ‑> Js_of_ocaml.Dom.node Js_of_ocaml.Js.t

scroll_container node finds the closest scrollable ancestor in the DOM tree. If there is no scrollable element above the node passed in, then the document will be returned
