我在带有自定义标题的 ng-table 中使用 Typeahead 和 Tooltip。这似乎在功能上起作用，如果您查看 plunker，您将永远不会注意到问题。但是，当您运行代码时，它会产生很多可以在控制台中看到的错误。每当我将鼠标悬停在其中一行上或从 Typeahead 中选择一个值时，都会在加载时生成错误。有谁知道如何解决这个问题？我已经为此工作了几天，但我还没有找到解决方案。

这是错误。

这是我的控制器代码

var app = angular.module('plunker', ['ui.bootstrap','ngTable' ]);

app.controller('MainCtrl', function($scope, $filter, ngTableParams) {
$scope.name = 'World';


$scope.testFilterText = "";

$scope.data = {};
$scope.data.selected = "";

$scope.testData = [{Name:"Han Solo",Role:"Smuggler"},{Name:"Luke Skywalker",Role:"Moisture Farmer"},{Name:"Princess Leia",Role:"Princess"},{Name:"Obie Wan Kenobi",Role:"Jedi Master"},{Name:"Chewbacca",Role:"Smuggler"},{Name:"Boba Fett",Role:"Bounty Hunter"},{Name:"Darth Vader",Role:"Sith Lord"},{Name:"Wedge Antilles",Role:"Pilot"},{Name:"C3PO",Role:"Protocol Droid"},{Name:"R2D2",Role:"Astromech Droid"},{Name:"Jabba The Hutt",Role:"Gangster"},{Name:"Greedo",Role:"Bounty Hunter"},{Name:"Darth Bane",Role:"Sith Lord"},{Name:"Yoda",Role:"Jedi Master"},{Name:"Mace Windu",Role:"Jedi Master"},{Name:"Commander Cody",Role:"Clone Trooper"},{Name:"Lando Calrissian",Role:"Entrepreneur"},{Name:"Mara Jade",Role:"Jedi"},{Name:"Lando Calrissian",Role:"Entrepreneur"},{Name:"Jango Fett",Role:"Bounty Hunter"},{Name:"Jar Jar Binks",Role:"Doofus"},{Name:"Darth Maul",Role:"Sith"},{Name:"Emporer Palpatine",Role:"Sith Lord"},{Name:"Qui-Gon Jinn",Role:"Jedi Master"},{Name:"Grand Moff Tarkin",Role:"Grand Moff"},{Name:"Lando Calrissian",Role:"Entrepreneur"},{Name:"Admiral Akbar",Role:"Admiral"},{Name:"IG-88",Role:"Bounty Hunter"}];


$scope.charactersTable = new ngTableParams({
  page:1,
  count: 10
},{
  counts: [10,20,50,100],
  total: $scope.testData.length,
  getData: function($defer, params) {
    var filteredData = params.filter() ?
    $filter('filter')($scope.testData, { 'Name': $scope.data.selected.Name }) :
    $scope.testData;
    var orderedData = params.sorting() ?
    $filter('orderBy')(filteredData, params.orderBy()) :
    $scope.testData;

    $scope.myOrderedData = orderedData.slice((params.page() - 1) * params.count(), params.page() * params.count());
    params.total(orderedData.length);
    $defer.resolve($scope.myOrderedData);
  }
});

$scope.$watch("data.selected.Name", function (newValue, oldValue) {
            if (newValue !== oldValue) {
                $timeout(function () {
                    $scope.charactersTable.reload();
                }, 100);
            }
        });


$scope.selectMatch = function (selection) {
    $scope.data.selected = selection;
    $scope.charactersTable.reload();
};

$scope.clearNameFilterText = function( evt ){
if (evt.keyCode === 13 && angular.isUndefined($scope.data.selected.Name) )  {
  $scope.charactersTable.reload();
}
}

});

这是html

我还创建了一个plunker，但是你不会在 plunker 上看到错误。当代码在本地或从 Web 服务器运行时会出现错误。

提前感谢您对此问题的任何帮助。

似乎是一个缺陷typeahead。

解决方法是这样的： - 初始化 $scope.matchestypeahead本身应该完成的。

  $scope.data = {};
  $scope.data.selected = "";
  $scope.matches = [];//workaround

工作小插曲：
