角度真的很新，但我有这个待办事项清单。我添加了一个模态按钮，我希望任务项在每个创建的模态中更新。出于某种原因，我无法使模式显示分配给它的任务项的正确名称。对于所有模态，它都会引用索引0。
second modal still reflecting first
这是html：
<header>
<ul class="nav nav-tabs">
<li role="presentation" class="active">
<a href="#/">Home</a>
</li>
<li role="presentation">
<a href="#/second">History</a>
</li>
</ul>
</header>
<center>
<div>
<div class="form-group">
<div class="col-xs-12 col-sm-8 col-md-4 col-lg-4 col-centered" id="nv">
<div class="row"></div>
<input ng-model="newItem" ng-keypress="addItem($event)" type="text" class="form-control lead" id="nv" placeholder="Add a grocery.">
</div>
</div>
</div>
</center>
<div id="mainBox">
<ul class="list-group checked-list-box" id="repeatBox">

<h7 id="lItem" class="lead" ng-class="{strike: deleted,notActive: deleted}">{{x.item}}</h7>

和js：

app.config(['$routeProvider', function($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'templates/home.html',
controller: 'homeCTRL'
})
.when('/second', {
templateUrl: 'templates/second.html',
controller: 'secondCTRL'
})
.otherwise({
redirectTo: '/'
});
}]);
//services
//history
app.service('carry', function() {
var transferAr = [];
var addList = function(newObj) {
transferAr.push({
item: newObj
});
};
var getList = function() {
return transferAr;
};
return {
addList: addList,
getList: getList,
};
});
//home temporary
app.service('hold', function() {
var holdTransferAr = [];
var holdAddList = function(newObj) {
holdTransferAr.push({
item: newObj
});
};
var holdGetList = function() {
return holdTransferAr;
};
return {
holdAddList: holdAddList,
holdGetList: holdGetList,
};
});
//controllers
app.controller('homeCTRL', ['$scope', 'carry', 'hold', '$log', function($scope, carry, hold, $log) {
$scope.newItem = '';
$scope.addItem = function(e) {
if (e.which === 13) {
hold.holdAddList($scope.newItem);
$scope.newItem = '';
}
};
$scope.displayHold = hold.holdGetList();
$scope.rmList = function(item) {
//get index of displayHold
$scope.index = $scope.displayHold.indexOf(item);
//add it to historylist
carry.addList($scope.displayHold[$scope.index].item);
//remove displayHold
$scope.displayHold.splice($scope.index, 1);
};
$scope.modalItem = function(item){
$scope.index = $scope.displayHold.indexOf(item);
return $scope.displayHold[$scope.index].item;
};
}]);
app.controller('secondCTRL', ['$scope', 'carry', function($scope, carry) {
$scope.controller2Ar = carry.getList();
}]);

答案 0 :(得分：1)
这是因为你的模态没有唯一的id和触发器：
为模态ID和触发器添加{{index}}或唯一标识符以显示模态。
