所以我已经验证我的contact.php（phpmailer文件）正在运行。但最后，如果回复成功，contact.php会说echo: 'done'
if(!$mail1->send()) {
echo 'error';
//echo 'Mailer Error: ' . $mail->ErrorInfo;
return false;
} else {
echo 'done';
return true;
}
那时（我猜是因为我付了开发人员为我创建了表单，但是最近还没有尝试用我自己的主机测试。这是他提供的代码。
/************
AJAX Method
*************/
function submitForm()
{
//1. user clicked on submit/send button after filling form
$('#contactform').on('submit',function(e){
//2. this line will prevent the window's reload!
e.preventDefault();
});//end form submit
//3. handilg the success div
$('#success_message').show();
$('#success_message h2').text('Processing, wait please...');
$('#submit_cf').attr('disabled','disabled');
//4. the actual ajx process starting from here
$formData = $('#contactform').serialize();
$.ajax({
url : "contact.php",
type: "POST",
data : $formData,
success: function(data) {
//data - response from server
//console.log(data);
if(data == 'done'){
$('#success_message h2').text('Mail Sent Successfully!');
}else{
$('#success_message h2').text('There is an error, try again later!');
// $('#submit_cf').attr('disabled','disabled');
}
}//end success
});//end ajax
}//end submitForm() function
})(jQuery, window, document);
</script>
我假设echo: 'data'，return: true将单词data发送回ajax表单，其中：
if(data == 'done'){
$('#success_message h2').text('Mail Sent Successfully!');
将接管并使用div#success_message h2填充Mail Sent Successfully html。
只有相反，ajax根本不起作用。相反，新页面只加载了“完成”一词（这是我在使用echo时所期望的：'完成'）。
我不知道如何让ajax接受'done'然后用成功消息填充同一页面。
我将jquery加载到标题中，因为它用于其他几个脚本。 ajax脚本位于html而不是外部脚本中。
请告诉我有一个简单的解决方法，还是我需要重新开始使用Swift？
答案 0 :(得分：1)
看完剧本后，它的设置有些奇怪。我会记下我认为你需要改变的内容，但首先回答你的问题：
我假设echo：'data'，return：true应该将单词数据发送回ajax表单...
不，data是从ajax页面返回的内容，在我的回答中我已将其更改为response，因此更清楚它的作用。它将包含成功/错误消息
相反，新页面只加载“完成”一词......
这个通常表示存在问题，或者首先没有加载jQuery，或者是否存在阻止jquery正常运行的错误，因此应该阻止表单正常提交的行（e.preventDefault()）被打断了。
我将jquery加载到标题中，因为它用于其他几个脚本。 ajax脚本位于html而不是外部脚本中。
这不应该太难以解决，你可以自己使用这个脚本而不是html。它必须在事件监听器之间而不是你的方式，并确保它在jQuery库加载之后放置：
<script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script type="text/javascript" src="/js/myScript.js"></script>
请告诉我有一个简单的解决方法，还是我需要重新开始使用Swift？
你不应该在Swift中重新开始
<强> /js/myScript.js
$(document).ready(function(){
// Make a function on this would make more sense, but you only need it if you
// want to re-use this feature, otherwise you can incorporate it back
// I made it as a function so it cleans up the submit a bit
function doSuccess(acton,message,disable)
{
$(acton).show();
$(acton+' h2').text(message);
$(disable).attr('disabled','disabled');
}
// It's strange to have the on('submit') inside the function since it's
// a listener, you shouldn't need to wrap this in a function, but wrap
// everything inside the listener instead
$('#contactform').on('submit',function(e){
// This is fine, it does prevent the form from submitting
e.preventDefault();
// Assign to variable this form
var thisForm = $(this);
// Run messaging
doSuccess('#success_message','Processing, please wait...','#submit_cf');
// Run ajax
$.ajax({
url : "contact.php",
type: "POST",
// You can serialize the form here
data : thisForm.serialize(),
success: function(response) {
// Just do the text here from php
$('#success_message h2').text(response);
}
});
});
});
在PHP方面，只需回显消息。由于您没有任何复杂的回报，因此更容易：
# You can use a ternary since there are only two options
echo ($mail1->send())? 'Your message sent successfully' : 'There is an error, try again later!';
# Unless there is a reason to return true or false (unless this is part of a
# function or method), you don't need it. It's not doing anything
最后一个注意事项，无论你使用submitForm()（可能是你的提交按钮或内联javascript），你应该能够删除它，因为该功能将不再存在。
编辑/只是作为一个侧面：我将演示如何执行此操作（尽可能简单的示例）以获得一致的结果并结束。在这个阶段对你来说可能太复杂了，但是，如果你感兴趣并阅读这些符号，那就很简单了。如果您复制所有内容并将它们放在我下面标记的正确文件夹中，您可以在决定实施之前先看到它的工作原理。
它涉及调度程序页面，xml页面和javascript ajax对象。我们的想法是，您可以使用xml作为自动化指令来构建它并执行自动化工作流程：
<强> /dispatcher.php
这是将接收您的ajax调用的页面。它将接收所有ajax调用并发送正确的指令。您可能希望在其中构建一些检查（例如表单令牌匹配），因为这种自动化可能很危险。这些是它的基础：
// Check specifically for actions
if(!empty($_POST['action'])) {
// This will fetch an xml file and parse it (see next section)
$config = simplexml_load_file(__DIR__."/xml/settings.xml");
// Assign the action
$action = $_POST['action'];
// Check the parsed file for the proper ajax action
if(!empty($config->ajax->action->{$action})) {
// Loop through the action
foreach($config->ajax->action->{$action} as $do) {
// If there is an include action
if(isset($do->{"include"})) {
// Loop through the includes
foreach($do->{"include"} as $include) {
// If the file exists, include it
if(is_file($inc = __DIR__.$include))
include($inc);
}
}
}
}
// Stop processing
exit;
}
<强> /xml/settings.xml
这只是一个基本的xml文件，可帮助您自动调用呼叫。这很直接。有一点需要注意，您需要将xml文件夹放在根目录之外，或者使用.htaccess（或web.config for Windows）来保护此文件夹不被访问，除了php。网上有一些例子。您可以展开此xml以包含具有<include>标记的多个页面，并且调度程序将一个接一个地运行。
<?xml version="1.0" encoding="UTF-8"?>
<config>
<ajax>
<action>
<!-- This would correlate to a hidden field in your form. See html form example -->
<email_user>
<include>/contact.php</include>
<!-- To run more actions on this call, just add another tag here -->
<!-- <include>/another/page/here.php</include> -->
</email_user>
</action>
</ajax>
</config>
<强> /js/myScript.js
这与上述版本略有不同。我会使用Ajax对象，因此可以重复使用。
// @param $ [object] This accepts jQuery object
var AjaxEngine = function($)
{
// Used to overwrite default url
var useUrl;
// Default url for call
var url = '/dispatcher.php';
// This is the do before function
var beforeFunc;
// This is the default do before
var useBefore = false;
// This is what overwrites the url (not needed in this instance)
this.useUrl = function(useUrl)
{
url = useUrl;
return this;
}
// This assigns the beforeSend action in ajax
this.doBefore = function(beforeFunc)
{
useBefore = beforeFunc;
return this;
}
// This is the actual send function
// @param data [object] This is what data to send to the dispatcher
// @param fun [object] This is the anonymous function that will run
// on success of the form
this.send = function(data,func)
{
$.ajax({
// Runs before the sending (this is where you add waiting messages)
beforeSend: useBefore,
url: url,
data: data,
type: 'post',
// This will take the response and drop it into the
// anonymous function
success: function(response){
func(response);
}
});
return this;
};
}
// Wait for document to be ready
$(document).ready(function(){
// If you use a class, you can act on any form that has the "ajax_form" class
// This is very powerful. It means you can have many different forms on
// the same page and use the same script/dispatcher to run/process each
$('.ajax_form').on('submit',function(e){
e.preventDefault();
var thisForm = $(this);
// Create new ajax engine, you have to pass jQuery for ajax to work
var Ajax = new AjaxEngine($);
// Set do before action, in your case you have 3 things that must
// happen before ajax sends. In this example, this function is fixed
// (not ideal), but you can add automation so you send the correct
// doBefore function on a per-form basis
Ajax.doBefore(function() {
$('#success_message').show();
$('#success_message h2').text('Processing, please wait...');
$('#submit_cf').attr('disabled','disabled');
})
// Send the form data and response function to "/dispatcher.php"
.send(thisForm.serialize(),function(response) {
// Do a "try/catch" here, that way you can catch errors
// Most common in this scenario would be an empty response, or
// mal-formed json (like a fatal error in php or whatever)
try {
// Parse the response
var parseResp = JSON.parse(response);
// See if there are instructions
var instr = (parseResp.instructions !== "undefined")? parseResp.instructions : 'text';
// Apply instructions, these are just some examples.
switch(instr) {
case('html'):
// Take from php apply html
$(parseResp.sendto).html(parseResp.data);
break;
default:
// Take from php apply text
$(parseResp.sendto).text(parseResp.data);
}
}
catch(Exception) {
// This will show you in the console what is wrong
console.log(Exception.message);
// This will show you what was received back so you can address issue
console.log(response);
}
});
});
});
<强>的index.php
网站根目录中的示例表单：
<form action="/tester.php" id="contactform" class="ajax_form">
<div id="success_message">
<h2>Hey</h2>
</div>
<input type="text" name="test" value="1050724273" />
<!-- Send this to the dispatcher and match the value in the xml file -->
<input type="hidden" name="action" value="email_user" />
<input type="submit" value="Save" />
</form>
<强> /contact.php
最后，这是将基于xml文件中的标记在我们的自动化中运行的页面。关键是返回json：
<?php
// Do all your code first, then output json at the very bottom
// For complex html output, do a buffer so you can capture it easily
ob_start();
?>
<h1>Hello people</h1>
<?php
// Get the above text/html from the buffer
$data = ob_get_contents();
// Clear out the buffer
ob_end_clean();
// This is what will be sent back as the "response" in the ajax
$response = array(
// This will tell the ajax where to drop the response
'sendto'=>'#contactform',//'#success_message h2',
// This is the content from above (<h1>Hello people</h1>)
'data'=>$data,
// This is just incase you want to expand out the ajax
// to include checks for success and failure
'success'=>true,
// This tells your ajax how to output using the switch
'instructions'=>'html'//'text'
);
// If you have extra includes that you want to run in the ajax call,
// don't die here, but in this instance, since there is only one include (contact.php),
// just die and output the response
die(json_encode($response));
