转换嵌套的HTML设置高亮报价标签(Converting nested html to bbCode

2019-09-22 16:44发布

我想转换下面的HTML

<div class="bbQuote">
    <div class="quoteAuthor">Joe Block</div>
    <div class="quoteContent">This is the first message<br>
        <div class="bbQuote">
            <div class="quoteAuthor">Jane Doe</div>
            <div class="quoteContent">This is the second message</div>
        </div>
    </div>
</div>

以下设置高亮

[quote=Joe Block]
    This is the first message
    [quote=Jane Doe]
        This is the second message
    [/quote]
[/quote]

我怎样才能做到这一点使用jQuery?

PS:嵌套HTML可以有零个或更多孩子

Answer 1:

这里是一个非常简单的例子:

var html = $('#commentContent').html(),
    beingParsed = $('<div>' + html.replace(/<br>/g, '\n\r') + '</div>'),
    $quote;
while (($quote = beingParsed.find('.bbQuote:first')).length) {
    var $author = $quote.find('.quoteAuthor:first'),
        $content = $quote.find('.quoteContent:first'),
        toIndent = $author[0].previousSibling;

    toIndent.textContent = toIndent.textContent.substring(0, toIndent.textContent.length-4);
    $author.replaceWith('[quote=' + $author.text() + ']');
    $content.replaceWith($content.html());
    $quote.replaceWith($quote.html() + '[/quote]');
}

var parsedData = beingParsed.html();

限制:

  1. 它不会其他HTML转换成BB代码( <b> <i>锚标签等);
  2. 压痕/白色空间不是100%准确。

我使用Ajax来获取从DB实际帖子内容或使用适当的jQuery BBCode的解析库。
