		<button onClick="Fun()">点击这里</button>

		<p id="DOWN" style="color: green; font-size: 24px; font-weight: bold;"> </p>

		<!-- Script to remove HTML element -->
		<script>
			var down = document.getElementById('DOWN');
			var meta = document.getElementById('remove'); //获取meta标签元素对象

			function Fun() {
				meta.parentNode.removeChild(meta);
				down.innerHTML = "元素被删除！";
			}
