使用 if(){} 切换到最后一个 mat-tab

Question

i got 3 mat tabs and i want to open the third tab (Tab 3) with if(){} when enter the page. Is it possible?

<mat-tab-group mat-align-tabs="center" style="width: 100%;" >
 <mat-tab label="Tab 1"></mat-tab>

 <mat-tab label="Tab 2"></mat-tab>

 <mat-tab label="Tab 3"></mat-tab>
</mat-tab-group>

Answer 1

You can use "selectedIndex" on mat-tab-group

example:

<mat-tab-group mat-align-tabs="center" style="width: 100%;" [selectedIndex]="selectedTab">
 <mat-tab label="Tab 1"></mat-tab>

 <mat-tab label="Tab 2"></mat-tab>

 <mat-tab label="Tab 3"></mat-tab>
</mat-tab-group>

and in Typescript:

selectedTab=0;
if(*/ condition */){
selectedTab= 2; */ tab number you want -1 */
}
