正则匹配img src遇到个问题，如何匹配src不带http的结果？

Question

如何匹配src中不带http的所有img 目前使用正则：<img.*?src="(.*?)".*?> 匹配结果： 需要匹配的段落： <p>在正方体<img src="https://www.abcd1234.com/20181222/1545460794504711.png" title="1545460794504711.png" alt="图片.png"/>中，E为棱CC₁的中点，则异面直线AE与CD所成角的正切值为<br/>A．<img src="/uploads/20181222/1545460825799217.png" title="1545460825799217.png" alt="图片.png"/> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp; B．<img src="/uploads/20181222/1545460832908668.png" title="1545460832908668.png" alt="图片.png"/> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; C．<img src="/uploads/20181222/1545460840101809.png" title="1545460840101809.png" alt="图片.png"/> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; D．<img src="/uploads/20181222/1545460849590046.png" title="1545460849590046.png" alt="图片.png"/></p><p><br/></p>

Answer 1

匹配不带http的结果 !/^<img.*http/.test(url)

Answer 2

转换下思路，匹配相对的path（以/）开头就可以了。

Answer 3

<img[^\>]*?src=\"\/([^\:]*?)\".*?\/>

Answer 4

<img.?src="\/(.?)".*?>
