jquery中郵箱地址 URL網站地址正則驗證實例代碼 QQ網站有一個網站舉報的功能，看了一些js代碼覺得寫得很不錯，我就拿下來了，下面是一個email驗證與url網址驗證js代碼，分享給大家

email地址驗證

復制代碼代碼如下: function checkEmail(){
??? var email=$.trim($("#report_email").val());
??? if(email == ""){
??????? $("#report_email").next('p').html("*請輸入郵箱地址!");
??????? return false;
??? }
??? var re = /^([a-zA-Z0-9]+[_|_|.]?)*[a-zA-Z0-9]+@([a-zA-Z0-9]+[_|_|.]?)*[a-zA-Z0-9]+.[a-zA-Z]{2,3}$/ig;
??? if(!re.test(email)){
??????? $("#report_email").next('p').html("*郵箱地址格式錯誤!");
??????? return false;
??? }
??? return true;
}

url地址驗證

復制代碼代碼如下:
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);
??? } // www.jbxue.com
??? 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; // www.jbxue.com
??? var urlText="請填寫舉報網站，您可以舉報多個網址，每行一個，一次不超過20個。";
??? if(!urls[0] || urls[0] == urlText){
??????? $("#report_url_list").val(urlText).css("color","#757575");
??????? $("#report_url_list").next('p').html('*請輸入正確的網址');
??????? $.urlfag=false;
??????? return false;
??? }
??? if(urls.length > 20){
??????????? $("#report_url_list").next('p').html("已超過20個，請分批舉報")
??????????? $.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:///, "");

??? if (a.indexOf("/") != -1) {
??????? a = a.substring(0, a.indexOf("/"));
??? }
??? var rg = /^((https?|ftp|news)://)?([w-]+.)+(.)+(:d+)?(/[w- ./?%&=]*)?$/i;
??? if(!rg.test(a)){
??????? urlError("格式錯誤",index,-1);
??????? return false;
??? }
??? if(inUrlArray(urls,index)){
??????? urlError("請不要舉報同一條網站",index,-1);
??????? return false;??
??? }
??? $.ajax({
??????? async:false,
??????? url:"http://api.pc.qq.com/tapi/url_report.php?url=http://"+a,
??????? dataType: "jsonp",
??????? method: "GET",
??????? success:function(a){
??????????? if(a.is_existed=="yes"){
??????????????? urlError("該網址已被舉報",index,-1);
??????????????? $.urlfag= false;
??????????? }
??????? }
??? });
??? urlError("正常",index,0);
??? return true;
}

function inUrlArray(urls,index){
??? var r=false
??????? for(i=index+1;i<urls.length;i++){
??????? a = urls[index].replace(/^http(s?):///, "");
??????? b = urls[i].replace(/^http(s?):///, "");
??????? if(a==b)
??????????? r=true;
??? }
??? return r;
}
function? urlError(msg,index,type){
??? type=type|| 0;
??? var test = $("#errorList div").find("span").eq(index);
??? test.show();
??? if(type<0){
?????? test.attr('title',msg).css("background-position","-20px 0px");
??? }else{
?????? test.attr('title',msg).css("background-position","0px 0px");
??? }
}
