我找不到适合我需要的脚本，所以我做了一个递归函数来检查损坏的图像，并尝试每四秒重新加载它们，直到它们修复。

我将它限制为10次尝试，因为如果它没有加载，那么图像可能不会出现在服务器上，函数将进入一个无限循环。不过我仍在测试中。请随意调整它:)

var retries = 0;
$.imgReload = function() {
    var loaded = 1;

    $("img").each(function() {
        if (!this.complete || typeof this.naturalWidth == "undefined" || this.naturalWidth == 0) {

            var src = $(this).attr("src");
            var date = new Date();
            $(this).attr("src", src + "?v=" + date.getTime()); //slightly change url to prevent loading from cache
            loaded =0;
        }
    });

    retries +=1;
    if (retries < 10) { // If after 10 retries error images are not fixed maybe because they
                        // are not present on server, the recursion will break the loop
        if (loaded == 0) {
            setTimeout('$.imgReload()',4000); // I think 4 seconds is enough to load a small image (<50k) from a slow server
        }
        // All images have been loaded
        else {
            // alert("images loaded");
        }
    }
    // If error images cannot be loaded  after 10 retries
    else {
        // alert("recursion exceeded");
    }
}

jQuery(document).ready(function() {
    setTimeout('$.imgReload()',5000);
});

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:

这是一个蹩脚的技巧，但它几乎是可以保证的:

<img onerror="this.parentNode.removeChild(this);">

我创建了一个小提琴来取代破碎的图像使用"onerror"事件。 这可能对你有帮助。

    //the placeholder image url
    var defaultUrl = "url('https://sadasd/image02.png')";

    $('div').each(function(index, item) {
      var currentUrl = $(item).css("background-image").replace(/^url\(['"](.+)['"]\)/, '$1');
      $('<img>', {
        src: currentUrl
      }).on("error", function(e) {
        $this = $(this);
        $this.css({
          "background-image": defaultUrl
        })
        e.target.remove()
      }.bind(this))
    })

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);
  });
});
