javascript - 使用 Angular 传递的数据更新模态

Question

对 Angular 来说真的很陌生，但我有这个待办事项列表。我添加了一个模式按钮，我希望任务项在每个创建的模式中更新。出于某种原因，我无法让模式显示分配给它的任务项的正确名称。它被卡在所有模态的引用索引 0 上。

first modal correct

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">
        <li class="list-group-item col-xs-12 col-sm-8 col-md-4 col-lg-4 col-centered" id="liBox" ng-repeat="x in displayHold" >
            <input type="checkbox" ng-model="deleted"></input>

            <h7 id="lItem" class="lead" ng-class="{strike: deleted,notActive: deleted}">{{x.item}}</h7>
            <button type="button" class="btn btn-default pull-right" ng-click="rmList(x)">
                <span class="glyphicon glyphicon-trash" id="icon"></span>
            </button>
            <button type="button" class="btn btn-default pull-right" data-toggle="modal" data-target="#myModal">
                <span class="glyphicon glyphicon-plus" id="icon"></span>
            </button>
            <div class="container">
                <div id="myModal" class="modal fade" role="dialog">
                    <div class="modal-dialog">
                        <div class="modal-content">
                            <div class="modal-header">
                                <button type="btn btn-default" class="close" data-dismiss="modal">&times;</button>
                                <h4 class="modal-title">{{modalItem(x)}}</h4>
                            </div>
                            <div class="modal-body lead">
                                <p>{{displayHold.x}}</p>
                            </div>
                            <div class="modal-footer">
                                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                            </div>
                        </div>
                    </div>
                </div>
            </div>
        </li>

    </ul>
</div>

和 js:

var app = angular.module('app', ['ngRoute']);

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();

}]);

second.html

<header>
    <ul class="nav nav-tabs">
        <li role="presentation">
            <a href="#/">Home</a>
        </li>
        <li role="presentation" class="active">
            <a href="#/second">History</a>
        </li>
    </ul>
</header>

<div id="mainBox">
    <ul ng-repeat="x in controller2Ar" class="list-group" id="repeatBoxAlt">
        <li class="list-group-item col-xs-12 col-sm-8 col-md-4 col-lg-4 col-centered lead strike">
          <center>
            <h7>{{x.item}}</h7>
          </center>
        </li>
    </ul>
</div>

这是index.html

Answer 1

这是因为您的模式没有唯一的 ID 和触发器:

将 {{index}} 或唯一标识符添加到模态 ID 和触发器以显示模态。
