第五行不应显示更多（更多）按钮，但会显示。任何人都可以帮助我吗？感谢。

Answer 1

似乎显示第五行的“更多”按钮，因为<ul>的高度超过18像素，即使该行中只有一条水平文本行。

如果我直接导航到http://shaojie.me/wp-content/example/buy.php，我看不到问题。

也许您应该使用更大的阈值，例如

// ...
if (ul.getSize().y > 24) {
    var store = true;
    ul.setStyle("height", "18px")
}
// ...

或者，使用“更智能”的测试 - 不依赖于<ul>的高度的测试。如何计算<li> s的数量？假设有4列<li> s，那么，

// ...
if (ul.getElements("li").length > 4) {
    var store = true;
    ul.setStyle("height", "18px")
}
// ...

javascript效果不正确
