jQuery / JavaScript来替换破碎的图像 [英] jQuery/JavaScript to replace broken images
问题描述
我有一个包含一堆图像的网页。有时图像不可用,所以在客户端的浏览器中会显示一张破碎的图像。
如何使用jQuery获取图像集,将其过滤为破碎图片然后替换src?
- 我认为用jQuery做这件事会更容易,但它转向使用纯粹的JavaScript解决方案,也就是Prestaul提供的解决方案更容易。
解决方案处理 onError
事件让图片使用JavaScript重新分配源代码: function imgError(image ){
image.onerror =;
image.src =/images/noimage.gif;
返回true;
< img src =image.pngonerror =imgError(this);/>
或者没有JavaScript函数:
< img src =image.pngonError =this.onerror = null; this.src ='/ images / noimage.gif'; />

I have a web page that includes a bunch of images. Sometimes the image isn't available, so a broken image is displayed in the client's browser.
How do I use jQuery to get the set of images, filter it to broken images then replace the src?
--I thought it would be easier to do this with jQuery, but it turned out much easier to just use a pure JavaScript solution, that is, the one provided by Prestaul.
Handle the onError
event for the image to reassign its source using JavaScript:
function imgError(image) {
image.onerror = "";
image.src = "/images/noimage.gif";
return true;
}
<img src="image.png" onerror="imgError(this);"/>
Or without a JavaScript function:
<img src="image.png" onError="this.onerror=null;this.src='/images/noimage.gif';" />
The following compatibility table lists the browsers that support the error facility:
