ecshop模板中如何实现局部刷新

建立一个ajax.js文件,代码如下:

// JavaScript Document var xmlHttp; function S_xmlhttprequest() { xmlHttp=null; if (window.XMLHttpRequest) {// code for IE7, Firefox, Opera, etc. xmlHttp=new XMLHttpRequest(); } else if (window.ActiveXObject) {// code for IE6, IE5 xmlHttp=new ActiveXObject("Microsoft.XMLHTTP"); } } function getName(name) { if(name = document.myform.name.value) { S_xmlhttprequest(); xmlHttp.open("get","date.php?name="+name,true); xmlHttp.onreadystatechange = byname; xmlHttp.send(null); } } function byname() { if(xmlHttp.readyState ==1) { document.getElementById(‘name’).innerHTML = "<font color=red>loading….</font>"; } if(xmlHttp.readyState == 4) { if(xmlHttp.status == 200) { var name = xmlHttp.responseText; document.getElementById(‘name’).innerHTML = name; } } } function getEmail(email) { var email = document.myform.email.value; if(email =="") { alert("用户名不能为空"); document.myform.email.focus(); return false; } else { S_xmlhttprequest(); xmlHttp.open("get","date.php?email="+email,true); xmlHttp.onreadystatechange = byemail; xmlHttp.send(null); } } function byemail() { if(xmlHttp.readyState ==1) { document.getElementById(’email’).innerHTML = "<font color=red>loading….</font>"; } if(xmlHttp.readyState == 4) { if(xmlHttp.status == 200) { var email = xmlHttp.responseText; document.getElementById(’email’).innerHTML = email; } } }

建立一个register.php文件,,代码如下:

<title>注册页面</title><script src="Ajax.js" language="javascript"></script><body><form action="" method="post" name="myform"><table align="center"><tr><td>用户名:</td><td><input type="text" name="name" value="" onblur="getName(‘name’)"/></td><td><div id="name"><font color="#CC66CC">*用户名必填*</font></div></td></tr><tr><td>邮箱:</td><td><input type="text" name="email" value="" onblur="getEmail(’email’)"/></td><td><div id="email"><font color="#CC66CC">*邮箱必填*</font></div></td></tr></table></form>建立一个date.php页面,用于查询数据库 :

<? sleep(1); $connt = mysql_connect("localhost","root","123456"); mysql_select_db(‘test’,$connt ); mysql_query("set names ‘gb2312’");if($_GET[‘name’]) { $name = $_GET[‘name’]; $sql = "select * from test where"; $restul = mysql_query($sql); $array = mysql_fetch_row($restul); // print_r($array); if(is_array($array)) { echo "<font color=’red’>该用户名已经存在</font>"; } else { echo "<font color=’red’>该用户名可以用</font>"; } } if($_GET[’email’]) { $name = $_GET[’email’]; $sql = "select * from test where email=’$email’"; $restul = mysql_query($sql); $array = mysql_fetch_row($restul); // print_r($array); if(is_array($array)) { echo "<font color=’red’>该邮箱已存在</font>"; } else { echo "<font color=’red’>该邮箱可以用</font>"; } }?>此即可实现,注册的时候局部刷新的效果……

旁观者的姓名永远爬不到比赛的计分板上。
