Pau*_*aul 2 javascript php ajax
我有一个执行AJAX函数的表单,以将表单值提交到PHP页面.PHP页面只是通过回显DIV中的变量来响应.
它适用于GET方法,但我无法使用POST.
<html>
<body>
<script language="javascript" type="text/javascript">
<!--
//Browser Support Code
function ajaxFunction(){
var ajaxRequest;
try{
// Opera 8.0+, Firefox, Safari
ajaxRequest = new XMLHttpRequest();
} catch (e){
// Internet Explorer Browsers
try{
ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try{
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e){
// Something went wrong
alert("Browser Not Supported");
return false;
}
}
}
// Get Response
ajaxRequest.onreadystatechange = function(){
if(ajaxRequest.readyState == 4){
document.getElementById("response").innerHTML = ajaxRequest.responseText;
}
}
var name=document.getElementById("name").value
var email=document.getElementById("email").value
ajaxRequest.open("POST", "process.php?name="+name+"&email="+email, true);
ajaxRequest.send(null);
}
//-->
</script>
<form name='Form1'>
Name: <input type='text' name='name' id="name"/> <br />
Email: <input type='text' name='email' id="email"/> <br />
<input type="button" value="Submit" onClick="ajaxFunction();">
</form>
<div id="response">
</div>
</body>
</html>
和php页面,process.php
<?php
echo date("H:i:s");
echo "<br/>";
// echo "Post Variables: ".$_POST['name']." ".$POST['email']; old code
echo "Post Variables: ".$_POST['name']." ".$_POST['email'];
echo "<br/>";
echo "Get Variables: ".$_GET['name']." ".$_GET['email'];
?>
我得到的回应是:
11:32:05发布变量:获取变量:输入的名称已输入电子邮件
所以我很确定这是从PHP传递到Javascript的变量.
非常感谢.
Run Code Online (Sandbox Code Playgroud)ajaxRequest.open("POST", "process.php?name="+name+"&email="+email, true); ajaxRequest.send(null);
那不是张贴变量.在这里,您将它们作为GET参数发送,并为您的POST请求提供一个空体.相反,使用
ajaxRequest.open("POST", "process.php", true);
ajaxRequest.send("name="+name+"&email="+email);
甚至更好
ajaxRequest.open("POST", "process.php", true);
ajaxRequest.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
ajaxRequest.send("name="+encodeURIComponent(name)+"&email="+encodeURIComponent(email));
