我正在使用数据列表在输入文本中自动完成。 我很好地初始化了它，但我想动态更新我的源代码和我的建议。
你知道如何做这样的事情吗？
HTML:
<input type="text" ng-model="title" list="suggestionList" ng-change="changeIsRaised()">
<datalist id="suggestionList">
<option data-ng-repeat="ttl in titles" value="{{ttl}}">
</datalist>
JavaScript:
$scope.titles = ["Action Comics", "Detective Comics", "Superman", "Fantastic Four", "Amazing Spider-Man"];
$scope.changeIsRaised = function() {
if ($scope.title == "ch") {
var newSrc = ["john", "bill", "charlie", "robert", "alban", "oscar", "marie", "celine", "brad", "drew", "rebecca", "michel", "francis", "jean", "paul", "pierre", "nicolas", "alfred", "gerard", "louis", "albert", "edouard", "benoit", "guillaume", "nicolas", "joseph"];
$scope.titles = newSrc;
}
}
最佳答案
您将“nicolas”列出了两次，导致 ng-repeat 错误。您可以添加一个 track by $index 来修复它，但您可能应该只删除重复项。
function ctrl($scope) {
$scope.titles = ["Action Comics", "Detective Comics", "Superman", "Fantastic Four", "Amazing Spider-Man"];
$scope.changeIsRaised = function() {
if ($scope.title == "ch") {
var newSrc = ["john", "bill", "charlie", "robert", "alban", "oscar", "marie", "celine", "brad", "drew", "rebecca", "michel", "francis", "jean", "paul", "pierre", "nicolas", "alfred", "gerard", "louis", "albert", "edouard", "benoit", "guillaume", "joseph"];
$scope.titles = newSrc;
}
}
}
angular.module('app', []).controller('ctrl', ctrl);<body ng-app="app">
<div ng-controller="ctrl">
<input type="text" ng-model="title" list="suggestionList" ng-change="changeIsRaised()">
<datalist id="suggestionList">
<option data-ng-repeat="ttl in titles" value="{{ttl}}">
</datalist>
</div>
