【问题描述】：
单击按钮后，我正在尝试在表格中打开 Bootstrap 下拉菜单。但是下拉菜单出现在表格下方，无论按下哪个按钮，都始终位于相同的位置。
有人遇到过同样的问题吗？是不是我缺少一些 css 位置？
我的目标是：每个下拉菜单都必须出现在按下的按钮下方。
这是一个演示：
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.filteredList = [];
$scope.servers = [
{
name: 'Server 1',
port: 5014
},
{
name: 'Server 2',
port: 5015
},
{
name: 'Server 3',
port: 5016
},
{
name: 'Server 4',
port: 5017
},
{
name: 'Server 5',
port: 5018
},
{
name: 'Server 6',
port: 5019
},
{
name: 'Server 7',
port: 5020
},
{
name: 'Server 8',
port: 8081
},
{
name: 'Server 9',
port: 8082
},
{
name: 'Server 10',
port: 8083
}
];
$scope.orderByField = "name";
$scope.orderByReverse = false;
$scope.currentPage = 1;
$scope.itemsPerPage = 5;
$scope.orderBy = function(field) {
if (field == $scope.orderByField)
$scope.orderByReverse = !$scope.orderByReverse
else {
$scope.orderByField = field;
$scope.orderByReverse = false;
}
};
})
.factory('Utils', function($timeout, $window) {
return {
getNormalizedString: getNormalizedString,
setFocus: setFocus
}
function getNormalizedString(str) {
str = str.toLowerCase();
str = str.replace(new RegExp("\\s", 'g'), "");
str = str.replace(new RegExp("[àáâãäå]", 'g'), "a");
str = str.replace(new RegExp("æ", 'g'), "ae");
str = str.replace(new RegExp("ç", 'g'), "c");
str = str.replace(new RegExp("[èéêë]", 'g'), "e");
str = str.replace(new RegExp("[ìíîï]", 'g'), "i");
str = str.replace(new RegExp("ñ", 'g'), "n");
str = str.replace(new RegExp("[òóôõö]", 'g'), "o");
str = str.replace(new RegExp("œ", 'g'), "oe");
str = str.replace(new RegExp("[ùúûü]", 'g'), "u");
str = str.replace(new RegExp("[ýÿ]", 'g'), "y");
str = str.replace(new RegExp("\\W", 'g'), "");
return str;
}
function setFocus(id) {
$timeout(function() {
var element = $window.document.getElementById(id);
if (element)
element.focus();
});
}
})
.filter('normalizedOrderBy', function(Utils, $filter) {
return function(list, orderByField, orderByReverse) {
function normalize(item) {
var value = item[orderByField];
if (typeof value === "string")
value = Utils.getNormalizedString(value);
// Forces the empty names to the end.
if (value === null || value === "")
return '~';
return value;
};
return $filter('orderBy')(list, normalize, orderByReverse);
}
})
.filter('normalizedFilter', function(Utils, $filter) {
return function(list, search) {
function comparator(actual, expected) {
// Filtro vazio ou nulo.
if (expected === "" || expected == null)
return true;
// Exatamente iguais.
if (actual == expected)
return true;
if (typeof actual === "string" && typeof expected === "string") {
actual = Utils.getNormalizedString(actual);
expected = Utils.getNormalizedString(expected);
return actual.indexOf(expected) > -1;
}
return false;
};
return $filter('filter')(list, search, comparator);
}
