為什么要提交此表格？

Question

我有一個問題，我想通過AJAX郵寄，我的問題是我的表格不斷提交。 由於某種原因，它會將所有表單刷新到URL中，但是我沒有使用GET發送任何內容？

HTML：

<form onsubmit="ajaxEmail();
        return false;" >
    <input type="text" name="name" id="name" value="Name" maxlength="1000" onfocus="this.value = this.value == 'Name' ? '' : this.value;" onblur="this.value = this.value == '' ? 'Name' : this.value;" />
    <input type="email" name="email" id="email" value="Email" maxlength="1000" onfocus="this.value = this.value == 'Email' ? '' : this.value;" onblur="this.value = this.value == '' ? 'Email' : this.value;" />
    <input type="text" id="subject"  value="Subject" maxlength="2000" onfocus="this.value = this.value == 'Subject' ? '' : this.value;" onblur="this.value = this.value == '' ? 'Subject' : this.value;" />
    <textarea name="Message" id="body" maxlength="40000" onfocus="this.value = this.value == 'Message' ? '' : this.value;" onblur="this.value = this.value == '' ? 'Message' : this.value;">Message</textarea>
    <input type="submit" value="send" class="submit-button"/>
</form>

JS：

$(function ajaxEmail() {
    $('#emailMsgResp').hide();
    $('#emailMsgBody').hide();

    var name = $('#name').val();
    var emailForm = $('#email').val();
    var subject = $('#subject').val();
    var message = $('#body').val();

    $.ajax({
        type: "POST", // Can be "GET"
        url: "../ajaxMail.php",
        data: {
        name: name,
        emailFrom: emailFrom,
        subject: subject,
        message: message
    },
    dataType: "json",
    success: function (data) {

        if (data['response'] == 1) {

            $('#emailMsgResp').show();
            $('#emailMsgResp').append('<div class="skill3" id="emailMsgBody" style="width:325px; height: 38px; margin: 0px auto;"><p>Thank you for contacting me' + data['response'] + '</p></div>');
            return false;

        } else if (data['response'] == 0) {

            $('#emailMsgResp').show();
            $('#emailMsgResp').append('<div class="skill3" id="emailMsgBody" style="width:325px; height: 38px; margin: 0px auto;"><p>Error: Please use your own client and write to contact@ivan-ristic.com</p></div>');
            return false;
        }
    }
    });
    return false;
});

ajaxMail.php

$email_it_to = 'mymail@mymail.com';

$name = $_POST['name'];
$email_from = $_POST['emailFrom'];
$subject = $_POST['subject'];
$body = $_POST['message'];

if(!isset($name) || !isset($email_from) || !isset($subject) || !isset($body)) {
    $response = 0;

} else {

    $email_from = $email;
    $email_subject = "Contact Form: ".stripslashes($subject);
    $email_message = "Below is a message submitted by '".stripslashes($name);
    $email_message .="' on ".date("d/m/Y")." at ".date("H:i")."\n\n";
    $email_message .= stripslashes($body);

    $headers = 'From: '.$email_from."\r\n" .

    'Reply-To: '.$email_from."\r\n" .
    'X-Mailer: PHP/' . phpversion();

    if (mail($email_it_to, $email_subject, $email_message, $headers)) {

        $response = 1;
    } else {

        $response = 0;
    }
}

echo json_encode($response);

Answer 1

您正在將函數分配為文檔就緒處理程序，因此頁面就緒后就會立即調用它。 你有：

$(function ajaxEmail() {
   /* your code */
});

...相當於：

$(document).ready(function ajaxEmail() {
    /* your code */
});

您應該擁有什么：

function ajaxEmail() {
   /* your code */
}

這將使您的函數成為可以從內聯事件屬性調用的全局函數。

或者，由於無論如何都在使用jQuery，請從表單中刪除內聯onsubmit=...處理程序，然后使用jQuery進行分配：

$(function() {
    $("form").submit(function(e) {
        e.preventDefault();

        /* your other function contents here */
    });
});

當然，最好給您的表單一個id屬性並使用$("#yourFormId").submit(...)而不是使用$("form").submit(...) （分配相同的值）處理頁面上的所有表單）。
