有条件地与react-router链接 [英] Conditionally linking with react-router Link

问题描述

我的React组件中有一种情况:如果 this.props.isComingFromModal 为false，我希望将某些元素包装在 Link 组件中.

I have a situation in my React component which is: i want some elements to be wrappend in a Link component if this.props.isComingFromModal is false.

我做了什么(JSX):

What i did (JSX):

<If condition={!this.props.isComingFromModal}>
  <Link
    to={{ pathname: `vendors/${benefit.vendor.id}`, state: { modal: false } }}
  >
    <img
      className="Benefit__vendor__thumb"
      src={benefit.vendor.tinyLogoUrl}
      alt="Ponto Frio"
    />


    <div className="Benefit__vendor__info">
      <h2 className="Benefit__vendor__title">{benefit.vendor.tradingName}</h2>
      <div className="rating">
        <Rating
          readonly
          initialRate={benefit.vendor.rating}
          className="rating"
          fractions={2}
          empty="icon-rating icon-rating--empty fa fa-star fa-2x"
          full="icon-rating fa fa-star fa-2x"
        />
      </div>
    </div>
  </Link>
  <Else />
    <img
      className="Benefit__vendor__thumb"
      src={benefit.vendor.tinyLogoUrl}
      alt="Ponto Frio"
    />


    <div className="Benefit__vendor__info">
      <h2 className="Benefit__vendor__title">{benefit.vendor.tradingName}</h2>
      <div className="rating">
        <Rating
          readonly
          initialRate={benefit.vendor.rating}
          className="rating"
          fractions={2}
          empty="icon-rating icon-rating--empty fa fa-star fa-2x"
          full="icon-rating fa fa-star fa-2x"
        />
      </div>
    </div>
</If>

但是我这是重复的.我不能只做(JSX)这样的事情吗?

But I this this is kind of repetitive. Can't I just do something like (JSX)

<Link
  to={{ pathname: `vendors/${benefit.vendor.id}`, state: { modal: false } }}
  condition={!this.props.isComingFromModal}
>
  <img
    className="Benefit__vendor__thumb"
    src={benefit.vendor.tinyLogoUrl}
    alt="Ponto Frio"
  />


  <div className="Benefit__vendor__info">
    <h2 className="Benefit__vendor__title">{benefit.vendor.tradingName}</h2>
    <div className="rating">
      <Rating
        readonly
        initialRate={benefit.vendor.rating}
        className="rating"
        fractions={2}
        empty="icon-rating icon-rating--empty fa fa-star fa-2x"
        full="icon-rating fa fa-star fa-2x"
      />
    </div>
  </div>
</Link>

在这种假设的情况下，即使 this.props.isComingFromModal ，我也会展示Link组件.有办法做到这一点吗?

In this hypothetical scenario, i would exhibit the Link component just if this.props.isComingFromModal. There is a way to do something this?

推荐答案

我的简单功能解决方案:

My simple functional solution:

const ConditionalLink = ({ children, to, condition }) => (!!condition && to)
      ? <Link to={to}>{children}</Link>
      : <>{children}</>;

然后您可以像这样使用它:

Then you can use it like this:

<ConditionalLink to="/path" condition={!isComingFromModal}
  conditional link
</ConditionalLink>
