【问题描述】：
我需要循环使用类.spr-review-content 的几个<div> 元素并获取每个<span class="image_src"> 的文本。然后将该文本用作该div 的附加<img> 的src。我几乎让它工作了，但是代码抓取了每个跨度的所有文本并将其用作每个图像的图像源，而不仅仅是那个跨度的文本。
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">
<div class="spr-review-header">
<span class="spr-starratings spr-review-header-starratings">
