正在开发一个b2c的国外商城,昨天做了一个历史浏览记录发出来跟大家分享一下.

JS：

//cookie相关函数

function getCookieVal(offset) {

    var endstr = document.cookie.indexOf(";", offset);

    if (endstr == -1) endstr = document.cookie.length;

    return unescape(document.cookie.substring(offset, endstr));

}

function getCookie(name) {

    var arg = name + "=";

    var alen = arg.length;

    var clen = document.cookie.length;

    var i = 0;

    while (i < clen) {

        var j = i + alen;

        if (document.cookie.substring(i, j) == arg) return getCookieVal(j);

        i = document.cookie.indexOf(" ", i) + 1;

        if (i == 0) break;

    }

    return null;

}

function setCookie(name, value) {

    var exp = new Date();

    exp.setTime(exp.getTime() + 3600000000);

    document.cookie = name + "=" + value + "; expires=" + exp.toGMTString();

}

function glog(evt) {

    var evt = evt ? evt : window.event;

    var srcElem = (evt.target) ? evt.target : evt.srcElement;

    try {

        while (srcElem.parentNode && srcElem != srcElem.parentNode) {

            if (srcElem.tagName && srcElem.tagName.toUpperCase() == "A") {

                addressCookie = srcElem.href;

                var ProductId = addressCookie.substr(addressCookie.indexOf("id=") + 3);

                var imgUrl = document.getElementById("img_" + ProductId + "").src;

                var productNameTitle = document.getElementById("Name_" + ProductId + "").text;

                var productName;

                if (productNameTitle.length > 28) {

                    productName = productNameTitle.substr(0, 25) + "...";

                }

                else {

                    productName = productNameTitle;

                }

                var productPrice = document.getElementById("Price_" + ProductId + "").textContent;

                address = srcElem.href + "+" + ProductId + "+" + imgUrl + "+" + productNameTitle + "+" + productName + "+" + productPrice + "|";

                wlink = address;

                old_info = getCookie("history_info");

                var insert = true;

                if (old_info == null) {//判断cookie是否为空

                    insert = true;

                }

                else {

                    var old_link = old_info.split("|");

                    for (var j = 0; j <= 5; j++) {

                        if (old_link[j].indexOf(addressCookie) != -1) //存在这个cookie

                            insert = false;

                        if (old_link[j] == "null")

                            break;

                    }

                }

                if (insert) {

                    wlink += getCookie("history_info");

                    setCookie("history_info", wlink);

                    history_show().reload();

                    break;

                }

                else {

                    var old_link1 = old_info.split("|");

                    var length = old_link1.length;

                    var newcookie = '';

                    for (var j = 0; length <= 6 ? j <= length - 1 : j <= 5; j++) {

                        if (old_link1[j].indexOf(addressCookie) == -1) {

                            if (j == length - 1 || j == 5) {

                                newcookie = newcookie + old_link1[j]

                            }

                            else {

                                newcookie = newcookie + old_link1[j] + '|'

                            }

                        }

                    }

                    newcookie = wlink + newcookie

                    setCookie("history_info", newcookie);

                    history_show().reload();

                    break;

                }

            }

            srcElem = srcElem.parentNode;

        }

    }

    catch (e) { }

    return true;

}

function history_show() {

        var history_info = getCookie("history_info");

        if (history_info != null) {

            history_arg = history_info.split("|");

            var content = "";

            for (var i = 0; history_arg.length >= 6 ? i<=5 : i<=history_arg.length - 1; i++) {

                if (history_arg[i] != "null") {

                    historyArry = history_arg[i].split("+");

                    content += "<li><div class=\"products_scan_pic\"><a οnclick=\"glog(event)\" href=\"ProductsInfo.aspx?id=" + historyArry[1] + "\"><img id=\"img_" + historyArry[1] + "\" src=\"" + historyArry[2] + "\" οnerrοr=\"javascript:this.src='images/Product/nophoto.jpg'\" width=\"47\" height=\"47\" /></a></div><div class=\"products_scan_txt\"><a href=\"ProductsInfo.aspx?id=" + historyArry[1] + "\" οnclick=\"glog(event)\" id=\"Name_" + historyArry[1] + "\" title=\"" + historyArry[3] + "\">" + historyArry[4] + "</a><br/><div id=\"Price_" + historyArry[1] + "\"><div class=\"products_seller_t2\">" + historyArry[5] + "</div></div></div></li>";

                }

            }

            document.getElementById("history").innerHTML = content;

        }

    else {

        document.getElementById("history").innerHTML = "<span style=\"color:#DE8500\">You have no recently viewed items or searches</span>";

    }

}

//清空cookies

function ClearHistory() {

    var exp = new Date();

    exp.setTime(exp.getTime() - 1);

    document.cookie = "history_info=;expires=" + exp.toGMTString() + "";

    document.getElementById("history").innerHTML = "<span style=\"color:#DE8500\">Cleared view history successfully</span>";

}

前台调用方式：

<script type="text/javascript" defer="defer">history_show();</script>

 

效果图：

 

清除历史浏览记录：

<div class="products_scan_title"><span><a href="#" οnclick="ClearHistory()">Clear History</a></span>Your last viewed items</div>

 

在这个项目之前我开发了一个类似"暴走漫画"搞笑图片制作的网站,现在网上很流行的搞笑图片,大多都来自那个网站,它的图片制作是用flash制作的,由于公司的某些策划和原因,我用asp.net开发了一个类似的,不过总感觉有瑕疵,这也是程序和flash的区别,无解!!.     网址:www.banmx.com    也希望有懂Gid.用asp.net开发过类似项目的朋友能给点意见. QQ357253950
