goquery thehhtml dy not not
我正在尝试使用“ github.com/puerkitobio/goquery”之前插入HTML元素。 则不会添加新元素。
package main
import (
"os"
"strings"
"github.com/PuerkitoBio/goquery"
)
var html = `
<section>
<article>
<h2>Article 1</h2>
<p>Text for article #1</p>
</article>
<article>
<h2>Article 2</h2>
<p>Text for article #2</p>
</article>
</section>
`
func main() {
qHtml, err := goquery.NewDocumentFromReader(strings.NewReader(html))
if err != nil {
panic(err)
}
section := qHtml.Find(`section`)
section.BeforeHtml(`<h1>Team Supreme</h1>`)
goquery.Render(os.Stdout, section)
}
不幸的是，如果我
section.BeforeHtml(`<h1>Team Supreme</h1>`)
不确定
section = section.BeforeHtml(`<h1>Team Supreme</h1>`)
正确的方法是什么是正确的方法，
I am trying to insert an html element before another html element using "github.com/PuerkitoBio/goquery". Unfortunately, the new element is not added ????
package main
import (
"os"
"strings"
"github.com/PuerkitoBio/goquery"
)
var html = `
<section>
<article>
<h2>Article 1</h2>
<p>Text for article #1</p>
</article>
<article>
<h2>Article 2</h2>
<p>Text for article #2</p>
</article>
</section>
`
func main() {
qHtml, err := goquery.NewDocumentFromReader(strings.NewReader(html))
if err != nil {
panic(err)
}
section := qHtml.Find(`section`)
section.BeforeHtml(`<h1>Team Supreme</h1>`)
goquery.Render(os.Stdout, section)
}
The same is true if I replace
section.BeforeHtml(`<h1>Team Supreme</h1>`)
with
section = section.BeforeHtml(`<h1>Team Supreme</h1>`)
Not sure what is the right way of doing it.

它不可见，因为您仅渲染选定的部分标签及其内容，但是附加的h1元素是在其进行附加h1标签之前可见的
BeforeHtmlis working as expected it is not visible since you are only rendering selected section tag and its content but the appendedh1element is before it to make appendedh1tag visible you have to update below lineTo
