Using the demo project of angular2-mdl as a guide I ported the tab component and tried to implement it as follow:
import { Component } from '@angular/core';
@Component({
selector: 'my-dashboard',
templateUrl: './landing.my.html'
})
export class MyDashboard {
public activeIndex = 0;
public tabChanged({index}): void {
this.activeIndex = index;
}
}
and the template is:
<mdl-tabs mdl-ripple mdl-tab-active-index="0" (mdl-tab-active-changed)="tabChanged($event)">
<mdl-tab-panel mdl-tab-panel-title="home">
<mdl-tab-panel-title>
<mdl-icon class="mdl-color-text--primary">home</mdl-icon><span>Home</span>
</mdl-tab-panel-title>
<mdl-tab-panel-content>
<ul>
<li>Stanis</li>
<li>Joffrey</li>
</ul>
</mdl-tab-panel-content>
</mdl-tab-panel>
<mdl-tab-panel mdl-tab-panel-title="something">
<mdl-tab-panel-title>
<mdl-icon class="mdl-color-text--primary">group_work</mdl-icon><span>Ontology</span>
</mdl-tab-panel-title>
<mdl-tab-panel-content>
<ul>
<li>Stanis</li>
<li>Joffrey</li>
</ul>
</mdl-tab-panel-content>
</mdl-tab-panel>
<mdl-tab-panel mdl-tab-panel-title="another">
<mdl-tab-panel-title>
<mdl-icon class="mdl-color-text--primary">list</mdl-icon><span>Cognitive</span>
</mdl-tab-panel-title>
<mdl-tab-panel-content>
<ul>
<li>Robert</li>
</ul>
</mdl-tab-panel-content>
</mdl-tab-panel>
<mdl-tab-panel mdl-tab-panel-title="else">
<mdl-tab-panel-title>
<mdl-icon class="mdl-color-text--primary">call_split</mdl-icon><span>Cognition</span>
</mdl-tab-panel-title>
<mdl-tab-panel-content>
<ul>
<li>Robert</li>
<li>Renly</li>
</ul>
</mdl-tab-panel-content>
</mdl-tab-panel>
<mdl-tab-panel mdl-tab-panel-title="last">
<mdl-tab-panel-title>
<mdl-icon class="mdl-color-text--primary">backup</mdl-icon><span>Streaming</span>
</mdl-tab-panel-title>
<mdl-tab-panel-content>

</mdl-tab-panel>
</mdl-tabs>
I am using webpack, and i get the following error:
ERROR in [default] home/my-app-ui/src/app/landing.my.ts:10:23
Binding element 'index' implicitly has an 'any' type.
however the app displays the desired functionality, can someone explain how to fix this ?
for an object, you need to declare the type as
{index} : {index:any}
use any
or specific type of the variable like ( numbers,string,etc )
public tabChanged(index:any): void {
this.activeIndex = index;
}
for an object, you need to declare like this way with one prop:
{propA} : {propA:any}
with more than one prop:
{propA, propB} : {propA:any, propB:any}
It is a check of the type script compiler. You can either remove the check or specify explicitly the any type in the declaration (answer from @Thyagu).
In the tsconfig.json
file, you could change the line
"noImplicitAny": false,
to
"noImplicitAny": true,
"suppressImplicitAnyIndexErrors": true //tsconfig.json
You can set a variable's type to any even when the noImplicitAny flag is true.
