使用javascript和PHP对每个类元素进行验证，然后从“下一步”按钮中删除禁用的类

我试图对每个类元素进行验证。我使用的表单有多个输入，具有相同的名称属性。我想验证每个输入元素

这是我的HTML

 <input type="text" class="date_of_birth" name="date[]" onkeyup="dateOfBirth('stepbirth')" />
 <span class="stepbirthVal"></span>
 <input type="text" class="date_of_birth" name="date[]" onkeyup="dateOfBirth('stepbirth')" />
 <span class="stepbirthVal"></span>
 <a href="javascript:;" id="stepbirth" class="btn disabled" onclick="kindKompas('stepbirth')">Next Step</a>

我希望你们能理解我的问题

提前感谢。

您应该循环查看以逗号分隔的日期字符串列表，验证每个字符串。以下是解决方案的模型：

<?php 

$fieldValue = "20/02/2000,03/05/2010";
$fieldName = "stepbirth";

//Validate the DOB
if ($fieldName == 'stepbirth')
{
    $birthDateLen = strlen($fieldValue);

    if ($birthDateLen > 9)
    {
        foreach (explode(",", $fieldValue) as $dateString) {
            echo $dateString;
            //Get Timestamp passed over
            $dt = DateTime::createFromFormat('d/m/Y', $dateString);
            //$userDate = $dt->getTimestamp();

            //Get Date 1 Year from Today
            $yearTime = date(strtotime('+10000 year'));

            //Get last 4 characters of the Date for the Year
            $year =  substr($fieldValue, -4);

            if ($year <= 1900)
            {
                echo '{"code":0,"message":""}';
            }
            else if ($userDate < $yearTime)
            {
                //If User's Date is Within 1 Year
                echo '{"code":1,"message":""}';
            }
            else
            {
                echo '{"code":0,"message":"Fill date to 365 days from now.}';       
            }
        }
    }
}

//Get Parameters Passed From the JS Call to This Script
$fieldValue = $_GET["q"];
$fieldName = $_GET["q2"];

//Validate the DOB
if($fieldName == 'stepbirth')
{
    $birthDateLen = strlen($fieldValue);

    if($birthDateLen > 9)
    {
        if (checkBirthDate($fieldValue))
        {
            //

            //Get last 4 characters of the Date for the Year
            $year =  substr($fieldValue, -4);
            if($year > 1900)
            {

                //Get Timestamp passed over
                $dt = DateTime::createFromFormat('d/m/Y', $fieldValue);
                $userDate = $dt->getTimestamp();

                //Get Date 1 Year from Today
                $yearTime = date(strtotime('+10000 year'));

                //If User's Date is Within 1 Year
                if($userDate < $yearTime)
                {
                    echo '{"code":1,"message":""}';
                }
                else
                {

                }
            }

        }
        else
        {
            echo '{"code":0,"message":"Please fill valid date of birth."}';
        }
    }

    else
    {
        echo '{"code":0,"message":""}';
    }
