我正在使用angular-ui的sortable-ui模块,并尝试引发取消,以便拖动的项目返回到源列表中的原始位置。不幸的是我不能让这个工作。这是一个例子:
var myapp = angular.module('myapp', ['ui.sortable']);
myapp.controller('controller', function ($scope) {
$scope.list = ["1", "2", "3", "4", "5", "6"];
$scope.list2 = ["7", "8", "9"];
$scope.sortableOptions = {
update: function(e, ui) {
if (Number(ui.item.text()) === 6) {
ui.item.parent().sortable('cancel');
}
},
receive: function(e, ui) {
ui.sender.sortable('cancel');
ui.item.parent().sortable('cancel');
},
connectWith: ".group",
axis: 'y'
};
});
angular.bootstrap(document,['myapp']);
任何帮助将不胜感激。

下面的示例有两个列表,第一个列表受限制 它的排序(更新方法) 和发送项目(列表2上的接收方法)
您可以排序的第二个列表,并将项目发送到列表1 (使用foundation4 for css)
<div ng-app="test">
<div ng-controller="sortableTest">
<div class="small-4 columns panel">
<ul data-drop="true"
ui-sortable="sortable.options.list1" ng-model="sortable.model.list1">
<li ng-repeat="fruit in sortable.model.list1"
data-id="{{ fruit.id }}">{{ fruit.label }}</li>
</ul>
</div>
<div class="small-4 columns panel">
<ul data-drop="true"
ui-sortable="sortable.options.list2" ng-model="sortable.model.list2">
<li ng-repeat="element in sortable.model.list2"
data-id="{{ element.id }}">{{ element.label }}</li>
</ul>
</div>
<div class="clear"></div>
<br />
<span ng-repeat="fruit in sortable.model.list1">{{ fruit.label }} </span><br />
<span ng-repeat="element in sortable.model.list2">{{ element.label }} </span><br />
<span ng-repeat="fruit in sortable.oldData.list1">{{ fruit.label }} </span><br />
<span ng-repeat="element in sortable.oldData.list2">{{ element.label }} </span><br />
</div>
</div>
js:
var test = angular.module('test', ['ui.sortable']);
test.controller('sortableTest', function($scope, $timeout) {
$scope.sortable = {
model: {
list1: [{id: 1, label: 'apple'},{id: 2, label: 'orange'},{id: 3, label: 'pear'},{id: 4, label: 'banana'}],
list2: [{id: 5, label: 'earth'},{id: 6, label: 'wind'},{id: 7, label: 'fire'},{id: 8, label: 'water'}]
},
oldData: {
list1: [],
list2: []
},
options: {
list1: {
update: function(event, ui) {
console.debug('up-list1');
$scope.sortable.oldData.list1 = $scope.sortable.model.list1.slice(0);
$scope.sortable.oldData.list2 = $scope.sortable.model.list2.slice(0);
// DO NOT USE THIS! it messes up the data.
// ui.item.parent().sortable('cancel'); // <--- BUGGY!
// uncomment and check the span repeats..
$timeout(function(){
$scope.sortable.model.list1 = $scope.sortable.oldData.list1;
$scope.sortable.model.list2 = $scope.sortable.oldData.list2;
});
},
connectWith: 'ul'
},
list2: {
update: function(event, ui) {
console.debug('up-list2');
},
connectWith: 'ul',
receive: function(event, ui) {
console.debug('re-list2');
$timeout(function(){
$scope.sortable.model.list1 = $scope.sortable.oldData.list1;
$scope.sortable.model.list2 = $scope.sortable.oldData.list2;
});
}
}
}
};
});
您当然可以使用服务或其他东西来存储旧值。如果你有两个以上,可以使用ui.sender来区分发送者..
