所有其他浏览器(Chrome 17,Firefox,IE9)运行良好。 IE7在“80行第6行”中给出了一个脚本错误。根据代码开头的注释,这是我上传的脚本。我不太了解javascript,但我没有看到80号线上的任何内容。代码在这里:

// tumblrBadge by Robert Nyman, http://www.robertnyman.com/, http://code.google.com/p/tumblrbadge/
var tumblrBadge = function () {
    // User settings
    var settings = {
        userName : "rs2006db", // Your Tumblr user name
        itemsToShow : 5, // Number of Tumblr posts to retrieve
        itemToAddBadgeTo : "tumblr", // Id of HTML element to put badge code into
        imageSize : 100, // Values can be 75, 100, 250, 400 or 500
        shortPublishDate : true, // Whether the publishing date should be cut shorter
        timeToWait : 2000 // Milliseconds, 1000 = 1 second
    };

    // Badge functionality
    var head = document.getElementsByTagName("head")[0];
    var badgeContainer = document.getElementById(settings.itemToAddBadgeTo);
    if (head && badgeContainer) {
        var badgeJSON = document.createElement("script");
        badgeJSON.type = "text/javascript";
        badgeJSON.src = "http://" + settings.userName + ".tumblr.com/api/read/json?callback=tumblrBadge.listItems&num=" + settings.itemsToShow;
        head.appendChild(badgeJSON);

        var wait = setTimeout(function () {
            badgeJSON.onload = null;
            badgeJSON.parentNode.removeChild(badgeJSON);
            badgeJSON = null;
        }, settings.timeToWait);

        listItems = function (json) {
            var posts = json.posts,
                list = document.createElement("ul"),
                title,
                titletext, 
                post, 
                listItem, 
                text, 
                link, 
                img, 
                conversation, 
                postLink;
            list.className = "tumblr";
            for (var i=0, il=posts.length; i<il; i=i+1) {
                post = posts[i];

                // Only get content for text, photo, quote and link posts
                if (/regular|photo|quote|link|conversation/.test(post.type)) {


                    listItem = document.createElement("p");
                    title = post["title"];
                    text = post["regular-body"] || post["photo-caption"] || post["quote-source"] || post["link-text"] || post["link-url"] || "";
                    if (post.type === "photo") {
                        link = document.createElement("a");
                        link.href = post.url;
                        img = document.createElement("img");
                        // To avoid a creeping page
                        img.width = settings.imageSize;
                        img.src = post["photo-url-" + settings.imageSize];
                        link.appendChild(img);
                        listItem.appendChild(link);
                        text = "<em>" + text + "</em>";
                    }
                    else if (post.type === "quote") {
                        text = post["quote-text"] + "<em>" + text + "</em>";
                    }
                    else if (post.type === "link") {
                        text = '<a href="' + post["link-url"] + '">' + text + '</a>';
                    }
                    else if (post.type === "conversation") {
                        conversation = post["conversation-lines"];
                        for (var j=0, jl=conversation.length; j<jl; j=j+1) {
                            text += conversation[j].label + " " + conversation[j].phrase + ((j === (jl -1))? "" : "<br>");
                        }
                    }
                    if (post.type === "regular") {
                        text = "<strong>" + post["regular-title"]+ "</strong>" + text;
                        text = "" + post["date"] + " - " + text;
                        text = "<br />" + text;
                    }

                    listItem.innerHTML += text || "";

                    // Apply list item to list
                    list.appendChild(listItem);
                }
            }

            // Apply list to container element
            badgeContainer.innerHTML = "";
            badgeContainer.appendChild(list);
        };

        return {
            listItems : listItems
        };
    }
}();

尝试替换此行(80):

listItem.innerHTML + = text || “”;

使用:

listItem.innerHTML =文字? listItem.innerHTML + text:“”;
