go - 雨果相当于PHP的strpos()

Question

因此，我想将.Content分解为适合不同的导航标签。如果有更好的模式可以完成，请告诉我。

因此，在我的/content/shop/product-name/index.md前面，问题包含:

# summary
summary: "This is the **product's** summary which will render markdown"
---
This is the first line of the full description of the product. This section of the ./index.md
page is referenced in the `single.html` file as `.Content`.|^^|This is the next part of the
.Content that I want to throw into a different nav-tab.

然后在/layouts/shop/single.html中:

   <div class="row">
     <div class="col-lg-12">
       {{ .Params.summary }}
     </div>
   </div> 
   <div class="row">
      <div class="col-lg-12">
        <nav class="product-info-tabs wc-tabs mt-5 mb-5">
          <div class="nav nav-tabs nav-fill" id="nav-tab" role="tablist">
            <a class="nav-item nav-link active" id="nav-home-tab" data-toggle="tab" href="#nav-home" role="tab"
              aria-controls="nav-home" aria-selected="true">Description</a>
            <a class="nav-item nav-link" id="nav-profile-tab" data-toggle="tab" href="#nav-profile" role="tab"
              aria-controls="nav-profile" aria-selected="false">Additional Information</a>
            <a class="nav-item nav-link" id="nav-contact-tab" data-toggle="tab" href="#nav-contact" role="tab"
              aria-controls="nav-contact" aria-selected="false">Reviews</a>
          </div>
        </nav>

        <div class="tab-content" id="nav-tabContent">
          <div class="tab-pane fade show active" id="nav-home" role="tabpanel" aria-labelledby="nav-home-tab">
            {{ .Content }}
          </div>
...

在过去的日子里，在PHP中，我可以使用strpos(.Content, '|^^|')然后使用substr(.Content, 0, (strpos(.Content, '|^^|'))来获取一段文本。您还可以使用用户配置的分隔符split('|^^|', .Content)将字符串放入数组中。

因此，回到Hugo，在.Content中，我可能会遇到类似以下情况:

This is the content. This is the last line before being split.|^^|This is the next line, that would be in array[1] or the next indexed substr.

我正在尝试将.Content的这两部分放入single.html页的不同选项卡中。每个产品的.Content显然都将有所不同，因此使用Hugo的substr()的数量我确实无法保持一致。

我看到的使用前件的问题是，尽管它是markdown呈现的，但它不能跨越多行。我知道我可以将\n用于换行符，但是这抵消了markdown的好处。

谢谢。

听起来您可能可以这样做:

{{ replace .Content "|^^|" "</div><div class='tab-pane fade show'>" | safeHTML}}

哪个会变成

      <div class="tab-pane fade show active" id="nav-home" role="tabpanel" aria-labelledby="nav-home-tab">
        This is the content. This is the last line before being split.|^^|This is the next line, that would be in array[1] or the next indexed substr.
      </div>

进入

      <div class="tab-pane fade show active" id="nav-home" role="tabpanel" aria-labelledby="nav-home-tab">
        This is the content. This is the last line before being split.
      </div>
      <div class='tab-pane fade show'>
        This is the next line, that would be in array[1] or the next indexed substr.
      </div>
