Question

我正在通过ajax和php验证用户电子邮件，但这里ajax始终显示电子邮件已退出;

AJAX / Javascript代码：

$.ajax({
    type: "POST",
    url: "classes/aeAjaxFunction.php",
    data: "do=sem&ci=" + ci11,
    success: function(msg) {
        if(msg ="yes") {
            alert('Email already exist');
        }
        else {
        // alert("Occured internal Error. please check network connection");
        }

        // $('#psid').html("<img src='images/spacer.gif'>");

        //$('#email1').html(msg);

        //

        //$('#sid').sSelect({ddMaxHeight: '300px'});

    },
    error: function() {
        // alert('some error has occured...');
    },
    start: function() {
        // alert('ajax has been started...');   
    }
});

PHP代码：

<?php

function checkSpEmail($postAr) {

    $mysqli = dbconn::get_mysqli();
    $email = $postAr['ci'];

    $selEmail = "SELECT fld_email FROM tbl_spouse WHERE fld_email = '$email' ";

    $res = mysqli_query($mysqli, $selEmail);
    $count = mysqli_num_rows($res);

    if (mysqli_num_rows($res) == 1) {
        echo 'yes';
        exit;
    }
}

?>

Answer 1

更改您的ajax代码，您使用的是msg = "yes"，您必须使用msg == "yes"

$.ajax({
    type: "POST",
    cache: false, 
    url: "classes/aeAjaxFunction.php",
    data: "do=sem&ci=" + ci11,
    success: function(msg) {
        if(msg == "yes") {
            alert('Email already exist');
        }
        else {
        // alert("Occured internal Error. please check network connection");
        }

        // $('#psid').html("<img src='images/spacer.gif'>");

        //$('#email1').html(msg);

        //

        //$('#sid').sSelect({ddMaxHeight: '300px'});

    },
    error: function() {
        // alert('some error has occured...');
    },
    start: function() {
        // alert('ajax has been started...');   
    }
});

Answer 2

更改

if(msg ="yes")

到

if(msg =="yes")

ajax总是显示电子邮件已经存在于此功能中的电子邮件
