使用ngFor Angular2

Question

我有一个问题因为我尝试使用'article'或'div'

错误：

 message: 'Can't bind to 'ngForFor' since it isn't a known property of 'div'.'



 message: 'Property binding ngForFor not used by any directive on an embedded template. Make sure that the property name is spelled correctly and all directives are listed in the "@NgModule.declarations".'


<section class='mycontainer'>
  <article *ngFor="let numberStep for steps; let i = index" 
    [ngClass]="article + i">
    <div class='line'></div>
    <div class='circle'></div>
  </article>
</section>

如何将* ngFor与分隔符一起使用？

抱歉我的英文。

Answer 1

应该是

*ngFor="let numberStep of steps; let i = index;"

您还需要确保已将CommonModule导入该组件的模块，文章

Answer 2

使用ngFor =“let numberStep of steps; let i = index”或ngFor =“let numberStep in steps; let i = index”

使用for * ngFor指令

时，你会犯错误
