    if(email == ""){
        $("#report_email").next('p').html("*请输入邮箱地址!");
        return false;
    }
    var re = /^([a-zA-Z0-9]+[_|_|.]?)*[a-zA-Z0-9]+@([a-zA-Z0-9]+[_|_|.]?)*[a-zA-Z0-9]+.[a-zA-Z]{2,3}$/ig;
    if(!re.test(email)){
        $("#report_email").next('p').html("*邮箱地址格式错误!");
        return false;
    }
    return true;

代码如下:
function getUrlArray(e, type){
    var urls = $.trim($("#report_url_list").val());
    urls = urls.replace(/s*n+s*/ig,"n");
    $("#report_url_list").val(urls);
        //format the urls
    if(type == "blur"){
        reportUrlElm.val(urls);
    }
    if(e && e.keyCode == 13){
        reportUrlElm.val(urls + "n");
    }

    urls = urls.split("n");
    user_urls = urls;
    return urls;
}
function checkurls(e, type) {
    $("#errorList").find("span").hide();
    urls = getUrlArray(e, type);
    var urlfag = true;
    url_index = 0;
    var urlText="请填写举报网站，您可以举报多个网址，每行一个，一次不超过20个。";
    if(!urls[0] || urls[0] == urlText){
        $("#report_url_list").val(urlText).css("color","#757575");
        $("#report_url_list").next('p').html('*请输入正确的网址');
        $.urlfag=false;
        return false;
    }
    if(urls.length > 20){
            $("#report_url_list").next('p').html("已超过20个，请分批举报")
            $.urlfag=false;
            return false;
    }
    $.urlfag=true;
    for(url_index=0;url_index<urls.length;url_index++){
        $.urlfag = checkEachUrl(urls, url_index)  && $.urlfag ;
    }
    return  urlfag;
}
function checkEachUrl(urls, index){
    var e=urls[index];
    a = e.replace(/^http:///, "");
