我正在使用ajax加载新的 HTML/JS 内容并将其附加到某个 div 块

问题是新的（收到的）代码包含一些图像标签，加载后它们不可见。当我直接复制图像的地址并检查它们时 - 一切都很好。

例如，在收到的代码中有：

<img srс="http://capitalpay.co.uk/images/vending/1.png" />

图片可以直接加载，但请查看此处的示例页面。

它不可用。也许我必须使用 JS 在收到的代码中预加载图像？

更新：

$.post('loadPage.php', {page: currentPage}, function(data) {
  $('#TextInside').html(data);
});

更新：

是的，问题出在src. 拉丁文“c”和西里尔文“c”在键盘上是同一个键。只是打字错误。

当您将代码加载到页面中时，无需预先加载图像。

使用 AJAX 在页面中包含代码不是问题。html代码本身存在一些问题。

如果您将该图像标签直接放在网页中，它也不会加载：http: //jsfiddle.net/fNNG8/

标签中的 inc有点奇怪。如果你只是删除它并写一个新的，它工作正常。srcimg

看到区别.....大声笑，也在这里

<?php

echo ord('с'); //this 'с' is copied from above text.

echo "<br/>";

echo ord('c');

结果
