range slider and local storage initialisation issue

I seem to be having a problem where by first visit to the page (presumably localstorage is empty at this point) and jplist shows "no results".
Interact with the slider and results appear.
Subsequent visits to the page (with localstorage now populated) and results show.

Any pointers for tracking this one down?

检查 jplist 中范围滑块的初始化代码，重点关注它在页面加载时如何从 localStorage 读取。检查当 localStorage 为空时是否设置了默认值。查看演示或测试页面以重现该问题。验证滑块在初始化后是否触发数据刷新以立即显示结果。
