demo project of angular2-mdl为指南,我移植了tab组件,并尝试如下实现:

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;
    }

}

模板是:
<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>
            <ul>
                <li>Joffrey</li>
                <li>Myrcella</li>
                <li>Tommen</li>
            </ul>
        </mdl-tab-panel-content>
    </mdl-tab-panel>
</mdl-tabs>

我正在使用webpack,出现以下错误:
ERROR in [default] home/my-app-ui/src/app/landing.my.ts:10:23
Binding element 'index' implicitly has an 'any' type.

但是应用程序显示了所需的功能,有人能解释一下如何解决这个问题吗?

最佳答案

Useanyor specific type of the variable like(numbers,string,etc)

public tabChanged(index:any): void {
    this.activeIndex = index;
}

关于angular - 绑定(bind)元素“索引”隐式具有“任意”类型,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/40745992/
