这是JavaScript，应该是跨浏览器兼容的，并且没有丑陋的标记onerror="":

var sPathToDefaultImg = 'http://cdn.sstatic.net/stackexchange/img/logos/so/so-icon.png',
    validateImage = function( domImg ) {
        oImg = new Image();
        oImg.onerror = function() {
            domImg.src = sPathToDefaultImg;
        };
        oImg.src = domImg.src;
    },
    aImg = document.getElementsByTagName( 'IMG' ),
    i = aImg.length;

while ( i-- ) {
    validateImage( aImg[i] );
}

CODEPEN:

我使用惰性加载，必须这样做，以使它正常工作:

lazyload();

var errorURL = "https://example.com/thisimageexist.png";

$(document).ready(function () {
  $('[data-src]').on("error", function () {
    $(this).attr('src', errorURL);
  });
});

(window.jQuery || window.Zepto).fn.fallback = function (fallback) {
  return this.one('error', function () {
    var self = this;
    this.src = (fallback || 'http://lorempixel.com/$width/$height').replace(
      /\$(\w+)/g, function (m, t) { return self[t] || ''; }
    );
  });
};
    

你可以传递一个占位符路径，并通过$*访问失败图像对象的所有属性:

$('img').fallback('http://dummyimage.com/$widthx$height&text=$src');

http://jsfiddle.net/ARTsinn/Cu4Zn/

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

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" );

我相信这就是你想要的:jQuery。预加载

下面是演示中的示例代码，你指定加载和未找到的图像，你就全部设置好了:

jQuery('#images img').preload({
  placeholder:'placeholder.jpg',
  notFound:'notfound.jpg'
});
