WordPress主题添加鼠标跟随特效代码

将鼠标跟随特效分享给喜欢花草的朋友。这种鼠标跟随效果还是很酷的。它不是那种追随很多零零碎碎的鼠标效果。只有一个圆圈跟随鼠标指针。遇到超链接，圆圈会变成半透明背景，是国外网站常见的类型，国外网站常见的一种的特效，具体效果看本站。

添加方法非常简单，将下面代码添加到当前主题函数模板 functions.php 最后：

// 加载jquery开始，如果主题已加载不加这段。
function zm_jquery_script() {
wp_enqueue_script( 'jquery' );
}
add_action( 'wp_enqueue_scripts', 'zm_jquery_script' );
// 加载jquery结束
function zm_mouse_cursor() { ?>
<!-- 必须的DIV -->
<div class="mouse-cursor cursor-outer"></div>
<div class="mouse-cursor cursor-inner"></div>
<!-- JS脚本 -->
<script>
jQuery(document).ready(function($){
var myCursor = jQuery('.mouse-cursor');
if (myCursor.length) {
if ($('body')) {
const e = document.querySelector('.cursor-inner'),
t = document.querySelector('.cursor-outer');
let n,
i = 0,
o = !1;
window.onmousemove = function(s) {
o || (t.style.transform = "translate(" + s.clientX + "px, " + s.clientY + "px)"),
e.style.transform = "translate(" + s.clientX + "px, " + s.clientY + "px)",
n = s.clientY,
i = s.clientX
},
$('body').on("mouseenter", "a, .cursor-pointer",
function() {
e.classList.add('cursor-hover'),
t.classList.add('cursor-hover')
}),
$('body').on("mouseleave", "a, .cursor-pointer",
function() {
$(this).is("a") && $(this).closest(".cursor-pointer").length || (e.classList.remove('cursor-hover'), t.classList.remove('cursor-hover'))
}),
e.style.visibility = "visible",
t.style.visibility = "visible"
}
}
})
</script>
<!-- 样式 -->
<style>
.mouse-cursor {

因默认主题未加载 jquery，所以代码中添加了 WP 自带的 jquery，如果你的主题已加载了 jquery，则不加第一段的代码(有注释)，大部分主题应该都加载了 jquery。

当然你也可以将样式添加到当前主题 style.css 中，包括 JS 代码也可以加到一个单独文件中加载。
