未捕获的类型错误：无法读取 Number.handleHover 处未定义的属性（读取“querySelectorAll”）

Question

我有一些 JavaScrupt 代码给出了此错误 Uncaught TypeError: Cannot readproperties of undefined (reading 'querySelectorAll')at Number.handleHover 。

 const handleHover = function (e) {
      if (e.target.classList.contains('nav-link')) {
        const link = e.target;
        const sibling = link
          .closest('.nav-wrap')
          .document.querySelectorAll('.nav-link');
        sibling.forEach(el => {
          if (el !== link) el.style.opacity = this;
        });
      }
    };
navSmooth.addEventListener('mouseover', handleHover.bind(0.5));
navSmooth.addEventListener('mouseout', handleHover.bind(1));
