这取决于您的要求，但如果您希望将替换限制为仅p标记内的文本。您可以修改jQuery以仅针对这些元素;

jQuery示例

var myCat = ['ABC', 'Hoo'],
    goUrl = new RegExp('(?<!<img[^>]*?)(' + myCat.join('|') + ')', 'g');

jQuery('.post-body p').html(function (_, curHtml) {
    return curHtml.replace(goUrl, "<a href='/search/label/$1'>$1</a>");
});

个字符

仅JavaScript示例

var myCat = ['ABC', 'Hoo'],
    goUrl = new RegExp('(?<!<img[^>]*?)(' + myCat.join('|') + ')', 'g');

document.querySelectorAll('.post-body p').forEach(function(element) {
    element.innerHTML = element.innerHTML.replace(goUrl, "<a href='/search/label/$1'>$1</a>");
});

<div class="post-body">
    <h1>Here is a header with ABC</h1>
    <p>This is a paragraph with ABC</p>
    <h2>Here is another header with Hoo</h2>
    <p>This is another paragraph with Hoo</p>
    <img src="https://example.com/image.jpg" alt="This is an image with alt text ABC and Hoo">
</div>
