layui下动态添加的select不显示问题解决

需要初始化

var sanji='';
						if(data.result=='success'){	
							 for(var i=0;i<data.sanji.length;i++){
									sanji+='<option value="'+data.sanji[i].id+'">'+data.sanji[i].nameZh+'</option>'
							}
							$("#sylysj_"+sortdiv).html(sanji); 
							syly_sj_html=sanji;
							layui.use(['form'], function () {
		        			var form = layui.form;
								layui.form.render('select');
							});
						}

初始化的代码

layui.use(['form'], function () {
		        			var form = layui.form;
								layui.form.render('select');
							});
