等效于C＃的简单“ for”（用索引迭代）

Question

在剃刀页上我可以写：

 @for (int i = 1; i <= Model.TotPages; i++)
    {
        <div class="pagmenu">
            @if (i == Model.CurPage)
            {
                @Html.ActionLink(i.ToString(), "Index", "Home", new { curPage = i, catId = Model.CatId, discounted = Model.Discounted, search= Model.Search }, new { @class = "btn btn-primary" })
            }
            else
            {
                @Html.ActionLink(i.ToString(), "Index", "Home", new { curPage = i, catId = Model.CatId, discounted = Model.Discounted, search = Model.Search }, new { @class = "btn btn-default" })
            }
        </div>
    }

等效角度是多少？* ngFor等同于foreach而非for，据我所知。

Answer 1

//in ts
n=10;

<div *ngFor="let a of ' '.repeat(n).split('');let i=index">
  {{i}}
</div>

或使用函数返回数组

//in .ts
n=10;
getFoolArray(n)
{
    return new Array(n)
}

<div *ngFor="let a of getFoolArray(n);let i=index">
  {{i}}
</div>

另一个选择是创建指令重复，请参见this SO answer
