    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;
}

url地址验证

复制代码 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);

    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").next('p').html('*请输入正确的网址');
        $.urlfag=false;
        return false;
    }
