如果你已经用innerHTML插入了img，比如:$("div")。innerHTML = <img src="wrong-uri">，你可以加载另一个图像，如果它失败了，例如:

<script>
    function imgError(img) {
        img.error="";
        img.src="valid-uri";
    }
</script>

<img src="wrong-uri" onerror="javascript:imgError(this)">

为什么javascript: _needed?因为通过innerHTML中的脚本标记注入DOM的脚本在注入时不会运行，所以必须显式。

jQuery 1.8

// If missing.png is missing, it is replaced by replacement.png
$( "img" )
  .error(function() {
    $( this ).attr( "src", "replacement.png" );
  })
  .attr( "src", "missing.png" );

jQuery 3

// If missing.png is missing, it is replaced by replacement.png
$( "img" )
  .on("error", function() {
    $( this ).attr( "src", "replacement.png" );
  })
  .attr( "src", "missing.png" );

参考

$(window).bind('load', function() {
  $('img').each(function() {
    if( (typeof this.naturalWidth != "undefined" && this.naturalWidth == 0) 
    ||  this.readyState == 'uninitialized'                                  ) {
        $(this).attr('src', 'missing.jpg');
    }
  });
});

对于React开发者:

<img 
    src={"https://urlto/yourimage.png"} // <--- If this image src fail to load, onError function will be called, where you can add placeholder image or any image you want to load
    width={200} 
    alt={"Image"} 
    onError={(event) => {
       event.target.onerror = "";
       event.target.src = "anyplaceholderimageUrlorPath"
       return true;
    }}
 />

我也有同样的问题。这个代码在我的案子上很有效。

// Replace broken images by a default img
$('img').each(function(){
    if($(this).attr('src') === ''){
      this.src = '/default_feature_image.png';
    }
});

这里有一个独立的解决方案:

$(window).load(function() {
  $('img').each(function() {
    if ( !this.complete
    ||   typeof this.naturalWidth == "undefined"
    ||   this.naturalWidth == 0                  ) {
      // image was broken, replace with your new image
      this.src = 'http://www.tranism.com/weblog/images/broken_ipod.gif';
    }
  });
});
