AddSearch UI自定义分页点击箭头始终跳转至第一页问题求助

我正在使用 addsearch-ui v0.7.11，尝试基于模板示例实现自定义分页，但点击箭头按钮时，无论当前处于哪一页，都会跳转至第一页。点击箭头按钮时会添加查询参数 &search_page=NaN，这可能是问题诱因。

以下是我的分页模板代码：

var paginationTemplate = `
  <div class="addsearch-pagination">
    {{#equals currentPage 1}}    
      <button disabled class="addsearch-pagination-disabled-button" aria-label="Previous page">
        <svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" viewBox="0 0 16 16" fill="none">

• 替换"previous"/"next"为具体页码值：addsearch-ui 的分页按钮 data-page 属性需要接收数字页码，而不是"previous"或"next"字符串。当传入字符串时，框架无法解析为有效数字，导致 search_page=NaN，最终回退到第一页。
  修改方式：

  • 上一页按钮：将 data-page="previous" 改为 data-page="{{currentPage - 1}}"
  • 下一页按钮：将 data-page="next" 改为 data-page="{{currentPage + 1}}"

• 验证模板语法支持：确认模板引擎支持算术运算（如 currentPage -1）。如果不支持，需要在模板渲染前计算好上一页和下一页的页码值，再传递给模板使用。

修改后的关键代码片段：

{{#gt currentPage 1}}
  <button data-page="{{currentPage - 1}}" aria-label="Previous page">
    <!-- SVG内容保持不变 -->
  </button>
{{/gt}}

{{#lt currentPage lastPage}}
  <button data-page="{{currentPage + 1}}" aria-label="Next page">
    <!-- SVG内容保持不变 -->
  </button>
{{/lt}}
