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);
  });
});

这是一个快速和肮脏的方法来替换所有破碎的图像，没有必要改变HTML代码;)

codepen例子

    $("img").each(function(){
        var img = $(this);
        var image = new Image();
        image.src = $(img).attr("src");
        var no_image = "https://dummyimage.com/100x100/7080b5/000000&text=No+image";
        if (image.naturalWidth == 0 || image.readyState == 'uninitialized'){
            $(img).unbind("error").attr("src", no_image).css({
                height: $(img).css("height"),
                width: $(img).css("width"),
            });
        }
  });

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;
    }}
 />

(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');

纯粹的JS。 我的任务是:如果图像'bl-once.png'是空的->插入第一个(没有404状态)图像从数组列表(在当前目录):

<img src=“http://localhost:63342/GetImage/bl-once.png” width=“200” onerror=“replaceEmptyImage.insertImg（this）”>

也许它需要改进，但是:

var srcToInsertArr = ['empty1.png', 'empty2.png', 'needed.png', 'notActual.png']; // try to insert one by one img from this array var path; var imgNotFounded = true; // to mark when success var replaceEmptyImage = { insertImg: function (elem) { if (srcToInsertArr.length == 0) { // if there are no more src to try return return "no-image.png"; } if(!/undefined/.test(elem.src)) { // remember path path = elem.src.split("/").slice(0, -1).join("/"); // "http://localhost:63342/GetImage" } var url = path + "/" + srcToInsertArr[0]; srcToInsertArr.splice(0, 1); // tried 1 src if(imgNotFounded){ // while not success replaceEmptyImage.getImg(url, path, elem); // CALL GET IMAGE } }, getImg: function (src, path, elem) { // GET IMAGE if (src && path && elem) { // src = "http://localhost:63342/GetImage/needed.png" var pathArr = src.split("/"); // ["http:", "", "localhost:63342", "GetImage", "needed.png"] var name = pathArr[pathArr.length - 1]; // "needed.png" xhr = new XMLHttpRequest(); xhr.open('GET', src, true); xhr.send(); xhr.onreadystatechange = function () { if (xhr.status == 200) { elem.src = src; // insert correct src imgNotFounded = false; // mark success } else { console.log(name + " doesn't exist!"); elem.onerror(); } } } } };

因此，它将插入正确的'needed.png'到我的src或'no-image.png'从当前目录。

CoffeeScript变体:

我这样做是为了修复Turbolinks的一个问题，该问题有时会导致.error()方法在Firefox中被引发，即使图像确实存在。

$("img").error ->
  e = $(@).get 0
  $(@).hide() if !$.browser.msie && (typeof this.naturalWidth == "undefined" || this.naturalWidth == 0)
