    $.ajax({
        method: "post",
        data: dataPosting,
        url: 'check_dup_email.php',
        success: function (data) {
            console.log(data);
            if (parseInt(data) === 1) {
                $('#email_status').html('Email already used');
                $('#cemail').focus();
                console.log('Already Exists');
            } else {
                console.log('carry on');
                $('#email_status').html('');
            }

        }

我尝试了我的表单的电子邮件验证...我想显示已存在的电子邮件，其中输入已在数据库中的电子邮件ID ...？请有人帮帮我吗？

你应该更改ajax代码。你的比较错误的响应值 .just 更改ajax代码中的比较值。

$.ajax({
    method: "post",
    data: {
            cemail : email
           },
    url: 'check_dup_email.php',
    success: function (data) {
        console.log(data);
        if ((data) == "equal") {
            $('#email_status').html('Email already used');
            $('#cemail').focus();
            console.log('Already Exists');
        } else {
            console.log('carry on');
            $('#email_status').html('');
        }

    }
});

php代码：

<?php 
    include_once("init.php");
    include_once'dbconfig.php';  
    //$email=filter_input(INPUT_POST,'cemail'); 
    $query="select * from stock_sales where st_email='purender@gmail.com' "; 
     $result = mysqli_query($conn,$query);
     $count=mysqli_num_rows($result); 
       if($count===1){ echo "equal"; } else{ echo "not equal"; }

电子邮件已经在jquery中存在验证
