无法弄清楚为什么 AJAX 没有触发答案

【问题标题】：Unable to figure out why AJAX is not triggering无法弄清楚为什么 AJAX 没有触发
【发布时间】：2016-09-06 12:06:14
【问题描述】：

我正在旋转我的轮子，试图找出我下面的代码有什么问题。由“.func2”标识的函数可以正常触发并执行它应该执行的操作。然而，当“.func1”函数被触发时（window.alert 'I am here' 正在显示），“.func1”中的 AJAX 调用没有触发。 “func2_email.php ....”没有被调用。

这两个函数都是从同一个 PHP 页面调用的。

任何想法为什么会发生这种情况？

    <script type="text/javascript">
$(function () {

     $(“.func1").on("click", function () {
        var fromEmail = $("#fromEmail").val();
        var toEmail = $("#to_Email").val();
        var transid = $("#refTransid").val();
        var repid = $("#initiatedby").val();
        var feed = $("#refFeed").val();
        var message = $("#to_message").val();
        var toName = $("#to_Name").val();
        var shareid = $("#shareid").val();

        //  window.alert(“I am here”);

        $.ajax({
            type: 'GET',
            url: “func2_email.php?fromEmail=" + fromEmail + "&toEmail=" + toEmail + "&toName=" + toName + "&message=" + message + "&shareId=" + shareid + "&transid=" + transid + "&repid=" + repid + "&feed=" + feed,
            dataType: "html",
            success: function (data) {
                $("#msg").html("<p class='successmsg'>" + toName + " has been notified");
            }               
        });
    });     

     $(“.func2").on("click", function () {

        var email = $(this).attr("email");
        var userid = $(this).attr("userid");
        var transid = $("#transid").val();
        var repid = $("#repid").val();
        var feed = $("#feed").val();

        var name = $(this).text();

        $.ajax({
            type: 'GET',
            url: “func1_email.php?userid=" + userid + "&feed=" + feed + "&transid=" + transid + "&repid=" + repid + "&email=" + email,
            dataType: "html",
            success: function (data) {
                var scrollTop    = $(document).scrollTop();
                var top          = parseInt(scrollTop+260);
                $("#msg").html("<p class='successmsg'>" + name + " has been notified </p>");

            }
        });
    });         

});
</script>

func2_email.php 的代码

    <?php
session_start();
require_once("classes/autoload.php");
$db     = new Database();

//$fromEmail  = $_GET["fromEmail"];     // If client wants to use their internal user names
$fromEmail = "admin@mydomain.com";  //Central email address
$toEmail  = $_GET["toEmail"];
$toName  = $_GET["toName"];
$message = $_GET["message"];
$shareId = $_GET["shareId"];
$transid  = $_GET["transid"];
$repid  = $_GET["repid"];
$feed  = $_GET["feed"];

$host = $db->getDbHost();
$companyname = $db->getFieldValue("companyname", "apphost", $host, "appsettings");

$body   = "Dear ".$toName."," ."</br>".$message."</br>Please click on the link below to view the page”."displaytransaction.php?transid=".$transid."&id=".$shareId."&requestor=".$repid."&feed=".$feed."<br></br>Sincerely, </br>Customer Operations</br>".$companyname;



$mail = new PHPMailer(true);  // the true param means it will throw exceptions on errors, which we need to catch

$mail->IsSMTP(); // telling the class to use SMTP
try {
$mail->Host       = "smtp.mailgun.org"; // SMTP server
$mail->SMTPDebug  = 2;                     // enables SMTP debug information (for testing)
$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->Port       = 2020;                    /
$mail->Username   = “postmaster@mydomain.com"; // SMTP account username
$mail->Password   = "d2e3d568bb45ea649661d86d6a553cf";        // SMTP account password


$mail->AddAddress($email);
$mail->SetFrom($fromEmail);
$mail->Subject = "Requesting you to join a live video sharing session on     transaction #". $transid;
$mail->MsgHTML($body);
$mail->Send();

echo "Message Sent OK<p></p>\n";
} catch (phpmailerException $e) {
echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {

echo $e->getMessage(); //来自其他任何东西的无聊错误消息！ }

【问题讨论】：

你能发布你的func2_email.php吗
检查浏览器中的网络选项卡，确保它确实没有被触发，也没有其他问题。
“ 是双引号吗？
@sr3z 这是 func2_email.php 的代码
在替换引号后为我工作。唯一的问题 - 是否故意“.func1”点击调用 func2_email ，反之亦然？我的意思是我需要点击 func1 来调用 func2_email

【解决方案1】：

我已签入我的编辑器并尝试在我的本地环境中运行此代码。进行了 Ajax 调用。请尝试一下，然后根据需要进行修改。

@Yonel，是的，那些是简单的 " 引号（就在 ENTER 键的左侧，带有 shift 键）
Chrome 或 Safari 中没有任何内容
