HTML

<div ng-app="app" ng-controller="testCtrl">
    {{chat.words}}
    <test ng-repeat="word in chat.words"></test>    
</div>

JS

var app = angular.module('app', []);
app.controller("testCtrl", function($scope) {
    $scope.chat = {
        words: [
            'Anencephalous', 'Borborygm', 'Collywobbles'
        ]
    };
});
app.directive('test', function() {
    return {
        restrict: 'EA',
        scope: {
            word: '='
        },
        template: "<li>{{word}}</li>",
        replace: true,
        link: function(scope, elm, attrs) {}
    }
});

OUTPUT

["Anencephalous","Borborygm","Collywobbles"]

预期产出

["Anencephalous","Borborygm","Collywobbles"]
•Anencephalous
•Borborygm
•Collywobbles

Answer 1

你没绑定word.

您已经使用了隔离范围.如果你没有绑定它的scope属性,它将无法工作.

scope: {
    word: '='
},

试试这样吧

<test word="word" ng-repeat="word in chat.words"></test>
