使用requirejs在主干网中使用jquery插件

using jquery plugin in backbone with requirejs

本文关键字：jquery 插件 requirejs 主干网 使用      更新时间：2023-09-26

我正在尝试使用这个插件：https://github.com/mattbryson/TouchSwipe-Jquery-Plugin在使用requirej的主干应用程序中，我想我一定不太了解requirej和主干是如何交互的。我读过各种各样的东西，所以我想确保我使用我建立的项目结构来完成这项工作，我认为这是相当常见的。这是我的应用程序：

我加载requirejs并传入主js文件：

<script src="/assets/js/bower_components/requirejs/require.js" data-main="/assets/js/app/main"></script>

在main.js中，我加载主干网的所有路径：

    require.config({
      paths: {
        jquery: '../bower_components/jquery/dist/jquery.min',
        underscore: '../bower_components/underscore/underscore',
        backbone: '../bower_components/backbone/backbone',
        touchswipe: '../bower_components/jquery-touchswipe/jquery.touchSwipe.min',
        templates: 'templates'
      }
    });
    require([
      'app',
    ], function(App){
      App.initialize();
    });
In app.js, I just initialize my router, and in router.js, I initialize my views:
    app_router.on('route:defaultAction', function (actions) {
            var homeView = new HomeView();
            homeView.render();
        });
In my view, I need to be able to figure out how to use the plugin. I can tell the source has loaded, but I can't call events as documented.

以下是一个示例视图：

define([
  'jquery',
  'underscore',
  'backbone',
  'text!templates/products/productsItemsTemplate.html',
  'collections/products/ProductsItemsCollection',
  'imagesloaded',
  'touchswipe'
], function($, _, Backbone,productsItemsTemplate,ProductsItemsCollection,imagesloaded,touchswipe){
imageLoader: imagesLoaded, //this plugin worked by defining it again here, but this feels like the wrong way to do things, and also, it didn't rely on a dom object in order to work, which i feel might be a problem with touchSwipe
touchSwipe: touchswipe,
el: $(".products-items-container"),
events : {
},
initialize: function(){
  $(".product-items-container").swipe( { //doesn't seem to work, but doesn't throw errors either
    swipe:function(event, direction, distance, duration, fingerCount, fingerData) {
      console.log(direction);
    },
     threshold:0
  });
},

请注意我对imageslooaded插件的评论，我开始工作了（尽管我思考的方式很奇怪）。

有人能把事情弄清楚吗？在标准javascript中使用这些插件似乎很容易，但主干网确实让我很失望。

一切似乎都很好：

require.config({
    paths: {
        "jquery": "//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min",
            "underscore": "https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.7.0/underscore-min",
            "backbone": "https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min",
            "text": "https://rawgit.com/requirejs/text/master/text"
    }
});
require(["jquery", "underscore", "backbone"], function ($, _, Backbone) {
    var view = Backbone.View.extend({
        initialize: function () {
            require(["//cdnjs.cloudflare.com/ajax/libs/jquery.touchswipe/1.6.4/jquery.touchSwipe.min.js"], function () {
                $("#test").swipe({
                    //Generic swipe handler for all directions
                    swipe: function (event, direction, distance, duration, fingerCount, fingerData) {
                        $(this).text("You swiped " + direction);
                    },
                    //Default is 75px, set to 0 for demo so any distance triggers swipe
                    threshold: 0
                });
            });
        }
    });
    new view();
});

我更喜欢只在需要插件的时候调用插件，如上面的代码所示。即使我们提前加载，它也能很好地工作。

require.config({
    paths: {
        "jquery": "//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min",
            "underscore": "https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.7.0/underscore-min",
            "backbone": "https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min",
            "text": "https://rawgit.com/requirejs/text/master/text",
            "swipe": "//cdnjs.cloudflare.com/ajax/libs/jquery.touchswipe/1.6.4/jquery.touchSwipe.min"
    }
});
require(["jquery", "underscore", "backbone", "swipe"], function ($, _, Backbone) {
    var view = Backbone.View.extend({
        initialize: function () {
            $("#test").swipe({
                //Generic swipe handler for all directions
                swipe: function (event, direction, distance, duration, fingerCount, fingerData) {
                    $(this).text("You swiped " + direction);
                },
                //Default is 75px, set to 0 for demo so any distance triggers swipe
                threshold: 0
            });
        }
    });
    new view();
});
