Question

我在我的网站（www.chrisanstey.co.uk）上运行一个AJAX联系表格，该表格不是仅在Firefox中提交，而是在其他所有浏览器中都可以正常使用。表单使用以下PHP文件：

<?php

$to = "me@somewhere.com"; //This is the email address you want to send the email to

if(!isset($_GET['action']))
{
die("You must not access this page directly!"); //Just to stop people from visiting contact.php normally
}

/* Now lets trim up the input before sending it */

$name = trim($_GET['name']); //The senders name
$email = trim($_GET['email']); //The senders email address
$subject = "A message sent from " . $name . " on Chris Anstey's portfolio"; //The senders subject
$message = trim($_GET['msg']); //The senders message

mail($to,$subject,$message,"From: ".$email.""); //a very simple send

echo 'contactarea|<p>Thank you '.$name.' for your message, I will reply to you as soon as I can.</p>'; //now lets update the "contactarea" div on the contact.html page. The contactarea| tell's the javascript which div to update.
?>

以及以下javascript文件：

function createRequestObject() {
    var ro;
    var browser = navigator.appName;
    if(browser == "Microsoft Internet Explorer"){
        ro = new ActiveXObject("Microsoft.XMLHTTP");
    }else{
        ro = new XMLHttpRequest();
    }
    return ro;
}

var http = createRequestObject();

function sendemail() {
 var msg = document.contactform.msg.value;
 var name = document.contactform.name.value;
 var email = document.contactform.email.value;
 document.contactform.send.disabled=true; 
 document.contactform.send.value='Sending....';

    http.open('get', 'contact.php?msg='+msg+'&name='+name+'&email='+email+'&action=send');
    http.onreadystatechange = handleResponse;
    http.send(null);
}

function handleResponse() {
    if(http.readyState == 4){
        var response = http.responseText;
        var update = new Array();

        if(response.indexOf('|' != -1)) {
            update = response.split('|');
            document.getElementById(update[0]).innerHTML = update[1];

        }
    }
}

表单位于Wordpress页面中，通过以下HTML在模板上调用：

<div id="contactarea">
<form name="contactform" id="contactform">
<p>Full Name:<br /> 
    <span class="wpcf7-form-control-wrap your-name"><input type="text" name="name"></span></p>
<p>Email:<br /> 
    <span class="wpcf7-form-control-wrap your-email"><input type="text" name="email"></span></p>
<p>Message:<br /> 
    <span class="wpcf7-form-control-wrap your-message"><textarea name="msg" rows="6" id="textarea"></textarea></span></p>
<p><input type="submit" value="Send Email" name="send" id="submitbutton" onClick="sendemail();"></p>
</form>
</div>

如果有任何想法或遇到类似的问题，AJAX无法在Firefox中运行，请您回复。任何帮助将不胜感激！

Answer 1

嗯，您的查询可以缓存一个。是不是在调用php？该代码在firefox中适用于我，但在它运行一次后，它应该缓存它，所以它不会再调用它。

Answer 2

我在firefox中测试了它并且ajax调用工作正常...我不认为这是问题..尝试在firefox上安装firebug插件所以我们可以看到错误消息是什么

修改如果我从你的评论中正确理解，当你点击提交按钮时页面就会改变，而你不想要...如果就是这样，那么只需将提交按钮上的onClick属性更改为

onClick="sendemail();return false;"

或将您的输入提交更改为输入按钮...这是因为当您单击提交按钮时，即使您有onClick事件，也会发送表单，因此return false应该停止它...当您想要阻止默认事件
时，它与链接相同祝你好运
