问题描述

我正在尝试使用此npm包

I am trying to use this npm package https://www.npmjs.com/package/masonry-layout

按照安装说明，我跑了：

As per install instruction I ran:

npm install masonry-layout --save

然后在我的文件中，

import '../../../node_modules/masonry-layout/dist/masonry.pkgd.min.js'

$('.blog-posts-container').masonry({
    // options ...
    itemSelector: '.card-blog',
    columnWidth: 200
})

我正在尝试在我的文件中导入包并运行它，但是我收到了这个错误：

I'm trying to import the package in my file and run it, but I get this error:

Uncaught TypeError: $(...).masonry is not a function

我认为我的导入存在问题。我做错了什么？

Im thinking there is something wrong with my import here. What am I doing wrong?

P.S。我正在使用webpack

P.S. I am using webpack

推荐答案

要使其正常工作，您需要使用，它使jQuery插件脱离了构造函数。

To get this to work, you need to use jQueryBridget which makes jQuery plugin out of a constructor function.

以下是使用的示例确保砌成图像加载后初始化。

Here's an example using the imagesloaded plugin to make sure masonry initializes after the images have loaded.

npm i -S jQueryBridget imagesLoaded

然后在 app.js （或其他）：

import $ from 'jquery';
import Masonry from 'masonry-layout';
import jQueryBridget from 'jquery-bridget';
import imagesLoaded from 'imagesloaded';

jQueryBridget('masonry', Masonry, $);
jQueryBridget( 'imagesLoaded', imagesLoaded, $ );

const $container = $('#masonry-grid');

$container.imagesLoaded(() => {
  $container.masonry({
    columnWidth: 200,
    itemSelector: '.item',
  });
});

以上内容应捆绑（使用Webpack）到 bundle.js 。

The above should be bundled (using Webpack) into bundle.js.

为了完整起见，这里是HTML：

And for the sake of completeness, here's the HTML:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Masonry Madness</title>
</head>
<body>
  <div id="masonry-grid">
    <div class="item">
