layer的一种用法，自己画出弹出框样式

/**导出报表类型选择  弹出框
	*/
	function selectExportType(){
		var template = '<div style="padding:50px;">';
			template +=	'<div class="layui-input-block"><input type="radio" id="subMaterial" name="subMaterial"  value="1" > <%=title_hasSubMaterialType %>  ';
			template +=	'<input type="radio" id="subMaterial" name="subMaterial" value="2" checked> <%=title_notHasSubMaterialType %>';
			template +=	'</div>';
			template +=	'<br>';
			template +=	'<div class="layui-input-block"><input type="radio" id="excelType" name="excelType" value="excel" > <%=title_excelType %>  ';
			template +=	'<input type="radio" id="excelType"  name="excelType" value="PDF" checked> <%=title_PDFType %>';
			template +=	'</div>';
			template +=	'<br>';
			template +=	'<br>';
			template +=	'<div class="layui-input-block">';
			template +=	'<button class="layui-btn" lay-submit lay-filter="formDemo" onclick="selectExportTypeConfirm();"><%=button_confirm%></button>';
			template +=	'</div>';
			template +=	'</div>';
		
		layer.open({
			  type: 1 //Page层类型
			  ,area: ['500px', '300px']
			  ,title: '<%=title_selectExportType %>'
			  ,closeBtn: 0 //不显示关闭按钮
			  ,shadeClose: true
			  ,shade: 0.6 //遮罩透明度
			  ,content: template
			});  
	}

	/**导出报表确定方法
	*/
	function selectExportTypeConfirm(){
		var bomMasterId = $("#hidden_bomMasterId").val();
		var subMaterial = $("input[name='subMaterial']:checked").val();
