使用codeigniter和ajax发送电子邮件，电子邮件已发送但出现错误消息

Question

I have this code written already by someone else, the problem is when sending the email it always show "Error Sending!" even that most of the times the email is sent successfully.

View (Form submission):

                        <!-- Contact Form Starts -->
                        <div class="col s12 m7 l9 xl9 rightside">
                            <h6 class="uppercase m-none">Feel free to drop me a line</h6>
                            <div class="row">
                                <p class="col s12 m12 l7 xl7 second-font">
                                    If you have any suggestions or consultations, please fill out the form below and I will reply shortly.

                            </div>
                            <form class="contactform" method="post" action="<?php echo site_url('en/send') ?>">

                        <!-- Contact Form Ends -->

Controller (send function):

    function send()
{

    $this->load->library('email');

    $config['mailtype'] = 'html';
    $config['charset'] = 'utf-8';
    $config['wordwrap'] = TRUE;

    $this->email->initialize($config);

    $body    = '
        <strong>Name: </strong>'.$this->input->post("name").'<br />
        <strong>Email: </strong>'.$this->input->post("email").'<br />
        <strong>Message: </strong>'.$this->input->post("message").'<br />
    ';

    $emailto = 'anemail@email.com'; //any email

    $this->load->library('email');

    $this->email->from($this->input->post("email"), $this->input->post("name"));
    $this->email->to($emailto);

    $this->email->subject('New Request');
    $this->email->message($body);

    $this->email->send();


    $data['contactus'] = $this->Emodel->contactus('en');
    $data['pages'] = $this->Emodel->get_pages('en');
    $data['social'] = $this->Emodel->get_header_social();
    $data['result'] = "Message Sent Successfully";


    $data['_title'] = "Contact";

    $this->load->view('en/home',$data);
}

JS file:

(function($) {

"use strict";

$(document).ready(function() {

    // PRELOADER
    $("body").toggleClass("loaded");
    setTimeout(function() {
        $("body").addClass("loaded");
    }, 3000);

    // PORTFOLIO DIRECTION AWARE HOVER EFFECT
    var item = $("#bl-work-items>div");
    var elementsLength = item.length;
    for (var i = 0; i < elementsLength; i++) {
        $(item[i]).hoverdir();
    }

    // TEXT ROTATOR
    $("#selector").animatedHeadline({
         animationType: "clip"
    });

    // BOX LAYOUT
    Boxlayout.init();

    // REMOVE # FROM URL
    $("a[href='#']").on("click", (function(e) {
        e.preventDefault();
    }));

    // AJAX CONTACT FORM
    $(".contactform").on("submit", function() {
        $(".output_message").text("Loading...");

        var form = $(this);
        $.ajax({

            url: form.attr("action"),
            method: form.attr("method"),
            data: form.serialize(),
            success: function(result) {
                if (result == "success") {
                    $(".contactform").find(".output_message").addClass("success");
                    $(".output_message").text("Message Sent!");
                } else {
                    $(".contactform").find(".output_message").addClass("error");
                    $(".output_message").text("Error Sending!");
                }
            }
        });

        return false;
    });

    // MATERIAL CAROUSEL
    $(".carousel.carousel-slider").carousel({
        fullWidth: true,
        indicators: true,
    });

    // RESUME CARDS ANIMATION
    if ($(window).width() > 800) {
        $(".resume-list-item, .resume-card").on("click", function() {
            $(".resume-list-item").removeClass("is-active");
            var e = parseInt($(this).data("index"),10);
            $("#resume-list-item-" + e).addClass("is-active");
            var t = e + 1,
                n = e - 1,
                i = e - 2;
            $(".resume-card").removeClass("front back up-front up-up-front back-back"), $(".resume-card-" + e).addClass("front"), $(".resume-card-" + t).addClass("back"), $(".resume-card-" + n).addClass("back-back"), $(".resume-card-" + i).addClass("back")
        });
    }

});

})(jQuery);

I don't have much knowledge in ajax and jquery so I copied the whole code

Because of Your Controller doesn't pass success data to the view use this code.

function send()
{
    $this->load->library('email');
    $config['mailtype'] = 'html';
    $config['charset'] = 'utf-8';
    $config['wordwrap'] = TRUE;

    $this->email->initialize($config);

    $body    = '
        <strong>Name: </strong>'.$this->input->post("name").'<br />
        <strong>Email: </strong>'.$this->input->post("email").'<br />
        <strong>Message: </strong>'.$this->input->post("message").'<br />
    ';

    $emailto = 'anemail@email.com'; //any email
    $this->load->library('email');
    $this->email->from($this->input->post("email"), $this->input->post("name"));
    $this->email->to($emailto);
    $this->email->subject('New Request');
    $this->email->message($body);
    if ($this->email->send()) {
       echo 'success';
    } else {
       echo 'error';
    }
}
