Layui modular page usage:
Load modules as needed
//引入js,css文件跳过,看文档 //在页面中,如同编写JavaScript一样 <script> layui.use(['layer','form'],function(){//需要加载的模块 var layer = layui.layer, form = layui.form;//初始化模块变量 layer.msg('Hi!');//调用该模块的方法 }) </script>
Load all modules at once
<script> ;!function(){ var layer = layui.layer ,form = layui.form;//初始化模块变量 layer.msg('Hello World'); }(); </script>
Self-written module
//js文件 layui.define(['layer'],function(exports){//自写模块需要调用的layui模块 var layer = layui.layer;//初始化模块变量 layer.msg('Hi!'); exports('index',{})//导出自写模块,index为导出名,use的时候名字要和导出一致 }) //use时注意需要设定模块所在目录 <script> layui.config({ base:'/res/js/modules/' //自建模块所在目录 }).use('index',function(){//加载入口 }); </script>
Local storage operation
layui.data('test',//test表名 {//对象 key:'user_name',//键值对 value:'用户1' } ) //删除 layui。data('test',{ key:'user_name',//需要删除的键 remove:true//删除 }) //查 var local = layui.data('test'); console.info(local.user_name); //根据删除的方法,我暂时认为,如果需要插入多个键值对,需要使用对象数组,而删除多个键值对,则未知了,因为没实际操作,因为本地存储其实不怎么会用这个,接入后端后大多用session或者redis
Various underlying methods that may not be used in practice
layui.device()//获取设备信息 layui.cache()//获得缓存 layui.extend(options)//拓展别名,给一个模块设置别名 layui.each(obj,fn)//对象(array,object,dom)遍历,可取代for layui.getStyle(node,name) //获得dom节点的style属性值,如document.body,'font-size' layui.img(url,callback,error)//图片预加载,可设置加载失败显示默认图从而避免图片加载失败没图的尴尬 layui.router()//获得路由 layui.hint()//向控制台输出异常,目前只能error,layui.hint().error('error') layui.stope(e)//阻止事件冒泡 layui.onevent(modName,events,callback)//自定义模块事件 layui.event(modName,events,params)//执行自定义事件 layui.factory(modName)//获取模块定义时的回调函数
