<!-- 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"
		}
	}
})
