一款簡單的無重新整理驗證手機號是否註冊：
用戶端實現：
<!DOCTYPE html><html><head><meta charset="utf-8"><style>#btn{width:80px;height:30px;}</style></head><body><form> 請輸入手機號：<input type="text" id="name" name="name"><input type="button" onclick="show()" id="btn" value="驗證"></form><p id="txt"></p><script>var usernamereg = /^1(3|4|5|7|8)\d{9}$/;function show(){var name=document.getElementById("name").value;var xmlHttp=new XMLHttpRequest();var url="post.php";xmlHttp.onreadystatechange=function stateChanged() { if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete"){ if(!usernamereg.test(name)){ document.getElementById("txt").innerHTML="手機號有誤";}else{ document.getElementById("txt").innerHTML=xmlHttp.responseText } }}xmlHttp.open("POST",url,true);xmlHttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");xmlHttp.send("name=" + name);} </script></body></html>
服務端實現：
<?php$con = mysqli_connect('localhost', 'username', 'password');if(! $con ){ die('串連失敗: ' . mysqli_error($con));}mysqli_select_db($con,'bdm256727651_db');$username = "select userName FROM Forms where userName = '$_POST[name]' ";$result = mysqli_query($con,$username );$rows=mysqli_num_rows($result);if($rows){echo "手機號登入";exit;}else{echo "手機號可用";}mysqli_close($con)?>
以上這篇ajax+php實現無重新整理驗證手機號的執行個體就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支援php中文網。
