我有一个下拉菜单,根据值的选择,应显示相应的div。
我尝试过以下代码。但它没有用。
export class PropertyComponent {
regTypeSelectedOption: string = "";
selectedNav: any; navs = ['option 1', 'option 2', 'option 3']
ngOnInit() {
this.selectedNav = 'select value';
}
setNav(nav:any){
this.selectedNav = nav;
if(this.selectedNav == "option 1"){
this.regTypeSelectedOption = "option 1";
}
else if(this.selectedNav == "option 2"){
this.regTypeSelectedOption = "option 2";
}
else if(this.selectedNav == "option 3"){
this.regTypeSelectedOption = "option 3";
}
}
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/2.0.0-beta.0/angular2.js"></script>
<div class="common_select_box">
<div class="input-group-btn dropdown {{dropdown1? 'open':''}}"
(click)="dropdown1=!dropdown1">
<button type="button" class="btn btn-default font_size_12 no_box_shadow
ticket_info_subline_text_color" dropdown-toggle=""
aria-haspopup="true" aria-expanded="false">{{selectedNav}}<span
class="caret" style="color: #bfbfbf;"></span> </button>
<ul class="dropdown-menu">
<li (click)="setNav(item)" *ngFor="let item of navs">{{item}}</li>
</ul>
<div *ngIf="regTypeSelectedOption == 'option 1'">
option 1
</div>
<div *ngIf="regTypeSelectedOption == 'option 2'">
option 2
</div>
<div *ngIf="regTypeSelectedOption == 'option 1'">
option 3
</div>
任何帮助都会很棒。
谢谢。
