【问题描述】：

app.js

$scope.add = function () {
  $('#btn').click(function() {
  // insert a SPAN tag with class="spn" at the end in all DIVs with      class="cls"
     $scope.data=[];
     var add=' <input type="text" name="currency" id="autocomplete">' ;
     $('div.cls').append(add);
     i++;
     $scope.count++;
  });
}

$scope.autocomplete=function(){
  var currencies = [
    { value: 'Afghan afghani' },
    { value: 'Albanian lek'},
    { value: 'Algerian dinar'},
    { value: 'European euro' }
  ];

  // setup autocomplete function pulling from currencies[] array
  $('#autocomplete').autocomplete({
    lookup: currencies,
  });
}

html

<div class="cls" id="idd"></div>
<button type="button" class="btn btn-default btn-sm" id="btn"> 
  <span class="glyphicon glyphicon-plus"></span> Add
</button>

这个自动完成功能在不使用 as append 的情况下运行。但是当我在像上面那样附加文本字段后使用它时它不起作用。谁能帮助我。

什么意思？？你的意思是，点击按钮后，再点击，就没有添加？？

这个示例向您展示了如何使用 Angular 创建自动完成功能，而无需 jQuery 自动完成功能。

var app = angular.module("app", []);
        app.controller("ctrl", function ($scope, $filter) {

            $scope.suggestions = [];

            $scope.selectedData = [];

            $scope.defaultData = [
                { value: "Afghan afghani" },
                { value: "Albanian lek" },
                { value: "Algerian dinar" },
                { value: "European euro" }
            ];

            $scope.search = function () {
                var length = $scope.autocomplete.length;
                if (length === 0) {
                    $scope.suggestionsNotFound = false;
                    $scope.suggestions = [];
                } else {
                    var result = $filter("filter")($scope.defaultData, { value: $scope.autocomplete });
                    $scope.suggestions = result;
                    $scope.suggestionsNotFound = false;
                    if (result.length === 0) {
                        $scope.suggestionsNotFound = true;
                    }
                }

                ///select
                $scope.select = function (item) {
                    var isExist = $filter("filter")($scope.selectedData, { value: item.value }, true)[0];
                    if (!isExist) {
                        $scope.selectedData.push(item);
                        $scope.autocomplete = null;
                        $scope.suggestions = [];
                    }
                }

                ///remove
                $scope.remove = function (index) {
                    $scope.selectedData.splice(index, 1);
                }

            }



        });

        .autocomplete span {
            margin-left: 5px;
        }

            .autocomplete span i {
                color: red;
                cursor: pointer;
            }
