<script>
document.getElementById('demo1-btn').onclick = function(){
	layer.open({
		type: 1,
		title: '多选',
		content: '<div id="demo1" class="xm-select-demo-alert"></div>',
		success: function(layero, index){
			//这里因为内容过少, 会被遮挡, 所以简单修改了下样式
			document.getElementById('layui-layer' + index).getElementsByClassName('layui-layer-content')[0].style.overflow = 'unset';
			//渲染多选
			var demo1 = xmSelect.render({
				el: '#demo1',
