Layui module introduction

The core of the layUI module is the two underlying methods of layui.js: one for defining the module, layui.define(), and one for loading the module, layui.use(). (Recommended: layui usage tutorial)

1. Pre-loading

Layui’s module loading uses the core layui.use(mods, callback) method. When your JS When you need to use the Layui module, we recommend that you use preloading, because this can avoid the trouble of writing layui.use everywhere. You should define it like this in the outermost layer:

2. Module namespace

layui’s module interface will be bound under the layui object, and is internally completed by the layui.define() method. Each module has a unique name and cannot be occupied. So you don’t need to worry about the module’s space being polluted unless you actively delete layui.{module name}. Calling the module can be achieved through the layui.use method, and then the module interface is obtained through the layui object. Such as:

layui.use(['layer', 'laypage', 'laydate'], function(){
  var layer = layui.layer //获得layer模块
  ,laypage = layui.laypage //获得laypage模块
  ,laydate = layui.laydate; //获得laydate模块
   
  //使用模块
});

Note: In fact, if you don’t want to use layui.use, you can introduce layui.all.js to replace layui.js, see: Non-modular usage

3, Expand a layui module

How to extend a Layui module:

Step one: Confirm the module name, assuming it is: mymod, then create a new mymod.js file and put it in any directory of the project (note : No need to put it in the layui directory)

The second step: Write test.js as follows:

/**
  扩展一个test模块
**/     
  
layui.define(function(exports){ //提示：模块也可以依赖其它模块，如：layui.define('layer', callback);
  var obj = {
    hello: function(str){
      alert('Hello '+ (str||'mymod'));
    }
  };
   
  //输出test接口
  exports('mymod', obj);
});

The third step: Set the directory where the extension module is located, and then you can add it to other JS files Used

//config的设置是全局的
layui.config({
  base: '/res/js/' //假设这是你存放拓展模块的根目录
}).extend({ //设定模块别名
  mymod: 'mymod' //如果 mymod.js 是在根目录，也可以不用设定别名
  ,mod1: 'admin/mod1' //相对于上述 base 目录的子目录
});
  
//你也可以忽略 base 设定的根目录，直接在 extend 指定路径（主要：该功能为 layui 2.2.0 新增）
layui.extend({
  mod2: '{/}http://cdn.xxx.com/lib/mod2' // {/}的意思即代表采用自有路径，即不跟随 base 路径
})
  
//使用拓展模块
layui.use(['mymod', 'mod1'], function(){
  var mymod = layui.mymod
  ,mod1 = layui.mod1
  ,mod2 = layui.mod2;
   
  mymod.hello('World!'); //弹出 Hello World!
});
