使用下拉菜单中的选项打开模态 - Angular 2 + ngx [英] Open a Modal Using an Option from a Dropdown - Angular 2 + ngx
问题描述
在 Angular 2/CLI 中使用 ngx-bootstrap (4).
Using ngx-bootstrap (4) with Angular 2/CLI.
尝试使用下拉列表来选择要打开的模式.如果每个模态只有一个按钮(不是下拉列表),模态当前可以正常工作,但要求需要下拉.
Trying to use a dropdown list to select which modal to open. The modal currently works fine if I just have a button for each modal (not a dropdown), but the requirements call for a dropdown.
我尝试过类似的东西
<select class="detailsOption" (change)="openModal($event.target.value)">
<option value="">Select Option</option>
<option value={{modal1}} >Option 1</option>
<option value={{modal2}}>Option 2</option>
</select>
<ng-template #modal1>
</ng-template
<ng-template #modal2>
</ng-template
openModal(template: TemplateRef<any>) {
this.modalRef = this.modalService.show(template);
}
显然这个例子行不通.但我试图找到一种方法,让选项值保存模板,然后在选择时,将模板传递给 openModal,然后打开模态.
Obviously this example wouldn't work. But I was trying to find a way have the option values hold the template, and then when selected, would pass the template into openModal and then open the modal.
我确实找到了这个家伙的问题,但没有答案,而且他在下拉菜单中使用了点击事件,我相信这并没有真正触发.ngx-bootstrap 从下拉列表中调用模态
I did find this guys question but it had no answers and also he was using click events in a drop down which don't really trigger I believe. ngx-bootstrap calling a modal from a dropdown
推荐答案
可以通过在select
的(change)
事件中打开模态来实现>
You can achieve this by opening the modal in the (change)
event of the select
<select class="detailsOption" (change)="openModal($event.target.value)">
<option value="">Select Option</option>
<option value="modal1" >Option 1</option>
<option value="modal2">Option 2</option>
</select>
<!-- Option 1 -->
<common-modal #childModalOption1 [title]="'Option1 modal'">
<div class="modal-body">Option 1 selected Modal </div>
</common-modal>
<!-- Option 2 -->
<common-modal #childModalOption2 [title]="'Option 2modal'">
<div class="modal-body">Option 2 selected Modal </div>
</common-modal>
您应该通过使用 @ViewChild
装饰器来装饰 modal-component
来获得多个引用
You should be having multiple references of the modal-component
by decorating them with @ViewChild
decorator
@ViewChild('childModalOption1') childModalOption1 :CommonModalComponent;
@ViewChild('childModalOption2') childModalOption2 :CommonModalComponent;
你的 openModal
方法应该是
openModal(event){
if(event==='modal1'){
this.childModalOption1.show()
console.log(event)
} else if(event==='modal2'){
this.childModalOption2.show()
}
}
