我需要循环几个<div>具有类 .spr-review-content 的元素并抓取每个 <span class="image_src"> 的文本。然后将该文本用作 src附加的<img>为此div 。我几乎可以正常工作，但代码会获取每个范围的所有文本，并将其用作每个图像的图像源，而不仅仅是该范围的文本。
代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Display Image Test</title>
<script src="https://code.jquery.com/jquery-3.3.1.min.js" integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8=" crossorigin="anonymous"></script>
</head>
<body>
<div class="spr-review" id="spr-review-49046513">

var img_src = $('.image_src').text();
$('<img />', {'class' : 'review_img', 'src' : img_src , appendTo : this});

最佳答案
你需要改变这个
var img_src = $(this).next('.image_src').text();
$('.spr-review-content').each(function() {
var img_src = $(this).next('.image_src').text();
$('<img />', {
'class': 'review_img',
'src': img_src,
appendTo: this
});
