jquery - jssor arrow navigators used to change slide? -

I have a jssor slider

while dragging the main slide, to highlight thumbnail list updates Slideshow

When clicking on the left or right arrow sliders, thumbnails run from the offset amount I would like for the first slide that appears in the new thumbnail list to show as the active slide.

I have seen and do not have an option for this, what would be the easiest way to achieve this effect?

Here's my current option setup:

  var option = {$ Autoplay: incorrect, // [optional] Automatically run to enable slideshow, The option should be set to the right, the default value is false $ AutoPlayInterval: 6000, sliding the default value is $ 3000, / / ​​(Optional) Interval (in milliseconds) Slider auto running before the slide closes before going to the previous slide Duration: 500, // [Optional] for slides in milliseconds The default period (swipe) specifies, the default value is $ 500, the drawRentation: 3, // [Optional] Orientation to drag the slide, 0 is not a drag, 1 horizontal, 2 vertical, 3 or so, the default value is 1 (note That $ $ $ should be similar to DrawOntation $ PlayOrientation is more than $ DisplayPieces 1, or Parking status is not 0) $ thumbnailNavigator option: {$ Class: $ JssorThumbnailNavigator $, // [Required] Thumbnail Navigator Instance for creating Class $ ChanceToShow: 2, // [required] 0 never, more than 1 mouse, 2 always $ loop: 1, // [Optional] Whether the loop of the carousel (circular) enabled or not, 0: stop, 1: loop, 2 Rewind, the default value is 1 dollar SpacingX: 14, // [Optional] In horizontal position pixels between each thumbnail, the default value is $ 0 SpacingY: 3, // [Optional] Workspace location between each thumbnail in pixels, default value 0 $ Cols: 4, // [Optional] Number of pieces to display, diff The value is 1 $ align: 0, // [Optional] Offset status to the thumbnail park, $ arronation option: {$ Class: $ JssorArrowNavigator $, // [recuridated] Class Arrow Navigator Example $ CHANCTO SHOW CREATE For: 2, // [required] 0 never, more than 1 mouse, 2 always $ step: 4 // [Optional] Steps to go for each navigation request, default value 1}}
