Jssor Slider drops Full Width (scale) on GoTo() method - jssor

Question

I am playing with JSSOR slider, it works perfect in fullwidth modal until we used GoTo() method to go to the specifed slide. For example, when slideshow initialised at slide (0) (no GoTo()), ScaleSlider() works. But when we tryin to force show slide (22), slider is showing within default boundaries (960x640). Maybe this is due to the use of LazyLoad ()? But by default (without GoTo()) it works fine with LazyLoad.
I use almost everything by default, no changes in the main code, even in options, only added strings
var jssor_slider_go = new $JssorSlider$("jssor_1");
jssor_slider_go.$GoTo(22);
after jssor container to force GoTo() method. BTW, The method works fine.

Answer 1

for some reason, the var jssor_slider_go = new $JssorSlider$("jssor_1");, initializes in delay mode. That's to say, `jssor_slider_go.$GoTo(22);' can't work before initialiation of jssor slider.
Use one of the following ways as workaround,
var jssor_1_options = { $StartIndex: 22 };
var jssor_slider_go = new $JssorSlider$("jssor_1", jssor_1_options);
See https://www.jssor.com/development/api-options.html
use setTimeout to run jssor_slider_go.$GoTo(22);

Answer 2

Good one:
var jssor_1_options = {
$StartIndex: 14,
$AutoPlay: 0,
$Idle: 2000,
$SlideEasing: $Jease$.$InOutSine,
$DragOrientation: 3,
$ArrowNavigatorOptions: {
$Class: $JssorArrowNavigator$
},
$BulletNavigatorOptions: {
$Class: $JssorBulletNavigator$
}
};
var jssor_1_slider = new $JssorSlider$("jssor_1", jssor_1_options);
And then:
var MAX_WIDTH = 10000;
var MAX_HEIGHT = 10000;
var MAX_BLEEDING = 0;
