Browserify - 如何在浏览器中调用通过 browserify 生成的文件中捆绑的函数 [英] Browserify - How to call function bundled in a file generated through browserify in browser

问题描述

我是 nodejs 和 browserify 的新手.我从这个 link 开始.

I am new to nodejs and browserify. I started with this link .

我有包含此代码的文件 main.js

I have file main.js which contains this code

var unique = require('uniq');

var data = [1, 2, 2, 3, 4, 5, 5, 5, 6];

this.LogData =function(){
console.log(unique(data));
};

现在我用 npm 安装 uniq 模块:

Now I Install the uniq module with npm:

 npm install uniq

然后我使用 browserify 命令将所有需要的模块从 main.js 开始打包到一个名为 bundle.js 的文件中:

Then I bundle up all the required modules starting at main.js into a single file called bundle.js with the browserify command:

browserify main.js -o bundle.js

生成的文件如下所示:

(function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);throw new Error("Cannot find module '"+o+"'")}var f=n[o]={exports:{}};t[o][0].call(f.exports,function(e){var n=t[o][1][e];return s(n?n:e)},f,f.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o<r.length;o++)s(r[o]);return s})({1:[function(require,module,exports){
var unique = require('uniq');

var data = [1, 2, 2, 3, 4, 5, 5, 5, 6];

this.LogData =function(){
console.log(unique(data));
};

},{"uniq":2}],2:[function(require,module,exports){
"use strict"

function unique_pred(list, compare) {
  var ptr = 1
    , len = list.length
    , a=list[0], b=list[0]
  for(var i=1; i<len; ++i) {
    b = a
    a = list[i]
    if(compare(a, b)) {
      if(i === ptr) {
        ptr++
        continue
      }
      list[ptr++] = a
    }
  }
  list.length = ptr
  return list
}

function unique_eq(list) {
  var ptr = 1
    , len = list.length
    , a=list[0], b = list[0]
  for(var i=1; i<len; ++i, b=a) {
    b = a
    a = list[i]
    if(a !== b) {
      if(i === ptr) {
        ptr++
        continue
      }
      list[ptr++] = a
    }
  }
  list.length = ptr
  return list
}

function unique(list, compare, sorted) {
  if(list.length === 0) {
    return []
  }
  if(compare) {
    if(!sorted) {
      list.sort(compare)
    }
    return unique_pred(list, compare)
  }
  if(!sorted) {
    list.sort()
  }
  return unique_eq(list)
}

module.exports = unique
},{}]},{},[1])

在我的 index.htm 页面中包含 bundle.js 文件后，如何调用 logData 函数??

推荐答案

默认情况下，browserify 不允许您从浏览器化代码外部访问模块——如果您想调用浏览器化模块中的代码，您应该将您的代码与模块一起浏览.有关示例，请参阅 http://browserify.org/.

By default, browserify doesn't let you access the modules from outside of the browserified code – if you want to call code in a browserified module, you're supposed to browserify your code together with the module. See http://browserify.org/ for examples of that.

当然，您也可以像这样从外部显式地访问您的方法:

Of course, you could also explicitly make your method accessible from outside like this:

window.LogData =function(){
  console.log(unique(data));
};

然后您可以从页面上的任何其他位置调用 LogData().

Then you could call LogData() from anywhere else on the page.
