[Feat]:引入自己编写javascript库示例

[exqmjmz]

这是一个引入自行编写的javascript库示例

自行编写的库需采用UMD modules方式引用

这是一个生成ulid的示例代码，通过以下代码可以生成ulid 1、保存成一个js文件，上传至可以对外访问，并且允许跨域的http服务上 2、通过设置中，高级选项，库安装，把自己的自定义库安装上 3、新建一个查询

(function (global, factory) {
    if (typeof define === "function" && define.amd) {
        define(["exports"], factory);
    } else if (typeof exports !== "undefined") {
        factory(exports);
    } else {
        var mod = {
            exports: {}
        };
        factory(mod.exports);
        global.ULID = mod.exports;
    }
})(this, function (exports) {
    "use strict";

            '8', '9', 'A', 'B', 'C', 'D', 'E', 'F',

                for (var i = 9; i >= 0; i--)
                    if (rand[i]++ < 255)
                        break;

    function generator(){
        var ulid = new ULID()
        return ulid()
    }
    // expose ulid to other modules
    exports.generator = generator;
});

运行查询后返回内容

umd-example最小demo，可以通过这个demo修改自己的库

// File log.js
(function (global, factory) {
  if (typeof define === "function" && define.amd) {
    define(["exports"], factory);
  } else if (typeof exports !== "undefined") {
    factory(exports);
  } else {
    var mod = {
      exports: {}
    };
    factory(mod.exports);
    global.log = mod.exports;
  }
})(this, function (exports) {
  "use strict";

  function log() {
    console.log("Example of UMD module system");
  }
  // expose log to other modules
  exports.log = log;
});
