我使用角度2来实现具有以下包的多重排序d& d https://www.npmjs.com/package/ng2-dnd
我能够将项目从一个容器拖放到另一个容器,反之亦然。 但是,当我过滤和项目,然后尝试拖动错误项目被拖放到另一个容器(通常应用该索引而不是实际存在的那个容器)。这可能是因为代码使用sortableIndex
以下是代码:
<div>
<h4>Groups</h4>
<div class="row">
<div class="col-sm-5">
<div class="panel panel-warning">
<div class="panel-heading">
Available Groups
</div>
<div>
<input type="text" class="form-control" name="" placeholder="search" [(ngModel)]="name"/>
</div>
<div class="panel-body" dnd-sortable-container [dropZones]="['boxers-zone']" [sortableData]="listBoxers">
<ul class="list-group" >
<li *ngFor="let item of listBoxers | DataFilterPipe: name; let i = index" class="list-group-item" dnd-sortable [sortableIndex]="i">{{item.name}}</li>
</ul>
</div>
</div>
</div>
<div class="col-sm-5">
<div class="panel panel-success">
<div class="panel-heading">
Selected Groups
</div>
<div class="panel-body" dnd-sortable-container [dropZones]="['boxers-zone']" [sortableData]="listTeamOne">
<ul class="list-group" >
<li *ngFor="let item of listTeamOne; let i = index" class="list-group-item" dnd-sortable [sortableIndex]="i">{{item.name}}</li>
</ul>
</div>
</div>
</div>
</div>
</div>
listBoxers:Array<object> = [];
listTeamOne:Array<object> = [];
this.listBoxers= [{id:"1",name:"ABC"}, {id:"2", name:"erwxyz"},{id:"2", name:"sdaxyz"},{id:"3", name:"sdxyz"},{id:"4", name:"xyz"}]
这是截图:
正如您在第二个屏幕截图中看到的那样,即使在过滤&#39; xyz&#39;之后,我也尝试对此项目进行评分。不管怎样,错误的项目被拖放(该指数存在的那个)
答案 0 :(得分:0)
我使用(ngModelChange)
代替过滤管(DataFilterPipe)
。然后为(ngModelChange)
写了一个自定义函数。这很有用。
