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)

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);
});

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。

通过使用Prestaul的答案，我添加了一些检查，我更喜欢使用jQuery的方式。

<img src="image1.png" onerror="imgError(this,1);"/>
<img src="image2.png" onerror="imgError(this,2);"/>

function imgError(image, type) {
    if (typeof jQuery !== 'undefined') {
       var imgWidth=$(image).attr("width");
       var imgHeight=$(image).attr("height");

        // Type 1 puts a placeholder image
        // Type 2 hides img tag
        if (type == 1) {
            if (typeof imgWidth !== 'undefined' && typeof imgHeight !== 'undefined') {
                $(image).attr("src", "http://lorempixel.com/" + imgWidth + "/" + imgHeight + "/");
            } else {
               $(image).attr("src", "http://lorempixel.com/200/200/");
            }
        } else if (type == 2) {
            $(image).hide();
        }
    }
    return true;
}

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';
    }
  });
});

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