Question

当人们将鼠标悬停在标签云中的任何项目上时，我需要添加一个onHover事件，这是代码..我认为某处存在冲突。现在它根本没有触发。

<html>
    <head>
        <title>jQCloud Example</title>
        <link rel="stylesheet" type="text/css" href="../jqcloud/jqcloud.css" />

Answer 1

使用jqcloud＆＃39; s "YOUR_IMAGE_NAME_FOR_SELECTED"在jqcloud完成制作你的wordcloud之后运行jquery

Answer 2

<强>原因

hover处理程序绑定到页面加载时尚不存在的span元素。因此，处理程序未绑定到动态添加的span元素。

<强>解决方案

不是直接绑定处理程序函数，而是应该将它在DOM的上方委托到页面加载时存在的父元素。

例如：

$("#my_favorite_latin_words").on('mouseenter', 'span', function() {
    alert('a');
});

不能使用jQuery Tag Cloud悬停
