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.

尝试使用下拉列表选择要打开的模式.如果我只为每个模式有一个按钮(而不是下拉菜单)，则该模式当前可以正常工作，但是要求调用一个下拉菜单.

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.

我尝试过类似的事情

<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，此示例不起作用.但是我试图找到一种方法来让选项值保存模板，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.

我确实找到了这个人的问题，但是没有答案，而且他在下拉菜单中使用了点击事件，但我相信这并不会真正触发. ngx-bootstrap从下拉菜单中调用模式

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

您可以通过在 select (更改)事件中打开模式来实现此目的>

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> 

您应该使用 @ViewChild 装饰器

@ViewChild('childModalOption1') childModalOption1 :CommonModalComponent;
@ViewChild('childModalOption2') childModalOption2 :CommonModalComponent;

您的 openModal 方法应为

openModal(event){
    if(event==='modal1'){
      this.childModalOption1.show()
      console.log(event)  
    } else if(event==='modal2'){
      this.childModalOption2.show()
    }
  }
