Question

我正在尝试使用diff2html和var jq = $.noConflict();

格式化Angular指令中的差异

我创建了一个Angular常量来保存jQuery，并将其传递给指令：

app.js

(function () { //IIFE to enable strict mode
    'use strict';

    angular.module('dashboard', ['ui.router', 'ngSanitize'])
        .config(['$interpolateProvider', function ($interpolateProvider) {
            $interpolateProvider.startSymbol('[[[').endSymbol(']]]');
        }])
        .constant('jQuery', window.jQuery);
})();

directive.js

(function () { //IIFE to enable strict mode

    'use strict';

    angular.module('dashboard')
        .directive("loadDiff", ['$http', 'jQuery', function($http, $) {
            return {
                restrict: "A",
                link: function(scope, elem, attrs) {

                    $http.get("diff url here").success(function (data) {
                        var diff2htmlUi = new Diff2HtmlUI({diff: data});
                        diff2htmlUi.draw('#line-by-line');
                    });
                }
            }
        }]);
})();

问题

运行时，我收到以下错误：

TypeError: $ is not a function at Diff2HtmlUI._initSelection at new Diff2HtmlUI

调试此项，您可以看到实例化Diff2HtmlUI时它会尝试设置正文，但由于与var jq = $.noConflict();的冲突，这可能会失败。

  Diff2HtmlUI.prototype._initSelection = function() {
    var body = $('body');
    var that = this;

如何解决此问题？我希望传递jQuery，因为$会覆盖noconflict冲突？

Answer 1

我真的不明白为什么要将jQuery传递给你的指令。由于您是直接加载的，因此您和diff2html已经可以通过全局window对象访问它。

此外，您可能只想传递指令element而不是外部div id，只需将其作为$(elem)传递，因为它需要jQuery对象或DOM查询字符串。

angular.module('dashboard', [])
  .config(['$interpolateProvider', function ($interpolateProvider) {
    $interpolateProvider.startSymbol('[[[').endSymbol(']]]');
  }])
  .constant('jQuery', window.jQuery)
  .directive('loadDiff', ['$http', function ($http) {
    return {
      restrict: 'A',
      link: function (scope, elem, attrs) {

        $http({
          url: 'https://api.github.com/repos/rtfpessoa/diff2html/pulls/106.diff',
          headers: {
            accept: 'application/vnd.github.v3.diff'
          }
        })
        .then(function (resp) {
          var diff2htmlUi = new Diff2HtmlUI({ diff: resp.data });
          diff2htmlUi.draw($(elem));
        })
          
      }
    }
  }]);
