如果我的HTML上有图片src,如下所示:
If I have a image src on my HTML as follow:

我想将所有$ _12.JPG更改为$ _57.JPG,以获得更好的图像质量,如下所示:
and I want to change all $_12.JPG to $_57.JPG in order to get the better image quality like below:
http://i.ebayimg.com/00/s/NzgwWDc4MA==/z/FrMAAOSweW5U3QvN/$_57.JPG?set_id=880000500F
我该如何使用Javascript来将HTML上的所有$ _12.JPG替换为$ _57.JPG?
How do I do this with Javascript so that it replaces all $_12.JPG on my HTML with $_57.JPG?
提前谢谢!!
推荐答案
您可以使用 .replace()
更改URL,例如:
You can change the URL using .replace()
for example:
document.getElementById('TheImage').src.replace('$_12.JPG','$_57.JPG');
这是一个小型演示,因此您可以在实际操作中看到它.
Here is a small demo so you can see this in action.
演示源代码
function URLswap(){
//--Set image variable
var curlink=document.getElementById('ebay');
//--Replace unwanted sting with new string.
var Newlink=curlink.src.replace('$_12.JPG','$_57.JPG');
//---Set new src
curlink.src=Newlink;
//-- Display new src (text) in div
document.getElementById('currentlink').innerHTML='New Src= '+Newlink;
}
<button onclick="URLswap()">Change</button><br>
<div id="currentlink">Current Src= http://i.ebayimg.com/00/s/NzgwWDc4MA==/z/FrMAAOSweW5U3QvN/$_12.JPG?set_id=880000500F</div>
<img id="ebay" src="http://i.ebayimg.com/00/s/NzgwWDc4MA==/z/FrMAAOSweW5U3QvN/$_12.JPG?set_id=880000500F"/>
对于多张图像,您可以为这些图像提供 class
并使用for循环将其应用于具有该类的所有图像,但是由于您的问题或提及中没有任何源代码 id
/ class
的内容我只是保持答案和问题一样基本.
For multiple image you can give those images a class
and use a for loop to apply this to all images with that class but since you don't have any source code in your question or any mention of id
/ class
I'm just keeping the answer as basic as the question.
我希望这会有所帮助.祝您编码愉快!
I hope this helps. Happy coding!
