简介：JS代码放到全局内容页尾（全局 : html > body ( footer_js_after )）<script> !function() { var coreSocialistValues = ["富强", "民主", "文明", "和谐", "自由", "平等", "公正", "法治", "爱国", "敬业", "诚信", "友善"], index = Math.floor(Math.random() * coreSocialistValues.length); document.body.addEventListener('click', function(e) { if (e.target.tagName == 'A') { return; } var x = e.pageX, y = e.pageY, span = document.createElement('span'); span.textContent = coreSocialistValues[index]; index = (index + 1) % coreSocialistValues.length; span.style.cssText = ['z index: 9999999; position: absolute; font weight: bold; color: #1976d2; top: ', y 20, 'px; left: ', x, 'px;'].join(''); document.body.appendChild(span); animate(span); }); function animate(el) { var i = 0, top = parseInt(el.style.top), id = setInterval(frame, 16.7); function frame() { if (i > 180) { clearInterval(id); el.parentNode.removeChild(el); } else { i += 2; el.style.top = top i + 'px'; el.style.opacity = (180 i) / 180; } } } }() </script>
