This slider is used to detect robots. If you slide it directly with a script, it will judge you as a robot.
In fact, its essence is not to ask you to slide over, but to detect whether your mouse behavior before, during, and after dragging is consistent with the characteristics of a real person

Look at the picture, the scroll bar is initialized with a span, which is the part you circle, and a p used to display the drag progress.
If you are only asking about the verification of reaching it
When dragging the span, the left of the span and the width of p.nc_1__bg change, then try to actively modify these two styles, and set the values to 258px, and then Click (or mousedown, mouseup) the span and find that the verification can be completed.

思路：修改style，然后触发span的click、mousedown、mouseup事件,因为不确定它具体是绑定在up还是down事件中（根据初步操作，应该是绑定在鼠标按下事件中），所以都触发一遍，至于click只是为了防漏.
代码：
     修改样式：就是修改p的width和span的left为258px，这里略过。
     js：$('#nc_1_wrapper #nc_1_n1z').click();    //触发单击事件
         $('#nc_1_wrapper #nc_1_n1z').mousedown();    //触发鼠标按下事件
         $('#nc_1_wrapper #nc_1_n1z').mouseup();    //触发鼠标弹起事件
