使用bootstrap模式处理angular2 EventEmitter
,但每当我通过子组件传递一些参数时,事件发射器角度只有在Bootstrap模式的情况下才解析为正确参数,否则一切正常。为什么?我做错了什么?
调用子组件编码(父组件) -
<ul>
<li *ngFor='#value of abc'>
<child-component (everySecond)="everySecond(value)"></child-component>{{view}}
</li>
</ul>
子组件编码 -
<div class="modal fade" id="delete_category" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header modal_header_color">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Delete</h4>
</div>
<div class="modal-body">
<div class="row margin_both">
<div class="col-md-12">
<div class="row form-group text-center">
<span>Are you sure you want to Delete !</span>
</div>
<div class="row form-group">
<div class="text-center">
<button type="button" class="btn btn-primary" data-dismiss="modal">Cancel</button>
<button type="button" class="btn btn-danger" (click)='call()' data-dismiss="modal">Delete</button> //not working
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
<button type="button" class="btn btn-danger" data-toggle="modal" data-target="#delete_category">
<span class="glyphicon glyphicon-trash"></span>
</button>
<---working ---->
<button (click)='call()' class='btn btn-info btn-sm'>Working Button</button> //works fine
<---working ---->

每个ChildComponent
元素使用相同的id="delete_category"
。 Bootstrap模式使用与id匹配的第一个模式,并且始终是第一个ChildComponent
与demoInput == 1
更改两行修复
<div class="modal fade" id="delete_category{{demoInput}}" role="dialog">
<button type="button" class="btn btn-danger" data-toggle="modal"
attr.data-target="#delete_category{{demoInput}}">
另请注意添加的attr.
属性绑定。
<强>更新强>
您可以在demoInput
中使用id="delete_category{{demoInput}}"
的随机值。
似乎没有必要使用与everySecond(value)
中相同的值。只有id
和attr.data-target
中使用的值必须在一个ChildComponent
内相同,而同时它们在不同的ChileComponent
之间需要不同。
我会用
class ChildComponent {
private static cmpId = 0;
// getter to make it available for binding from the template
// because this doesn't work with statics
private get componentId() => ChildComponent.prototype.cmpId++;
// I'm not sure if this ^^^ is the correct way to access static
// fields in TypeScript.
}
<div class="modal fade" id="delete_category{{componentId}}" role="dialog">
<button type="button" class="btn btn-danger" data-toggle="modal"
attr.data-target="#delete_category{{componentId}}">
