javascript - 我如何检查日期是否是今天，然后使用 jquery 打印特定文本？

Question

我有以下代码:

.today-tag {margin-left:10px;color:red};

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="day">Sunday<span class="today-tag"></span></div>
<div class="day">Monday<span class="today-tag"></span></div>
<div class="day">Tuesday<span class="today-tag"></span></div>
<div class="day">Wedsday<span class="today-tag"></span></div>
<div class="day">Thursday<span class="today-tag"></span></div>
<div class="day">Friday<span class="today-tag"></span></div>
<div class="day">Saturday<span class="today-tag"></span></div>

我想在星期几旁边添加“今天”这个词。有没有办法使用 jquery 检查日期是否是今天？我已经尝试过类似的方法，但没有用。

var getdate = new Date();

if(getdate == new Date()) {
$('.today-tag').text("TODAY")
}

在我的 php 文件中，我使用此代码输出商店的开/关时间:

<?php if ( $res=FunctionsV3::getMerchantOpeningHours($merchant_id)):?>
<?php foreach ($res as $val):?>
<div class="row">
 <div class="col-md-3 col-xs-4 "></i> 
 <?php echo t($val['day'])?>
 <span class="today-tag"></span>
 </div>
 <div class="col-md-6 col-xs-6 "><?php echo $val['hours']?></div>
 <div class="col-md-3 col-xs-3"><?php echo $val['open_text']?></div>
 </div>
 <?php endforeach;?>
 <?php else :?>
 <p class="text-danger"><?php echo t("Not available.")?></p>
 <?php endif;?>

好吧，只是为了好玩。

var today = new Date().getDay();
var days = [
    'Sunday', 'Monday', 'Tuesday', 'Wedsday', 'Thursday', 'Friday', 'Saturday'
];
var daysContainer = document.getElementById('days');
days.forEach((day, index) => {
    day = today === index ? day + ' today': day;
    daysContainer.innerHTML += `
        <div class="day">${day}<span class="today-tag"></span></div>
    `;
});

#today-tag {margin-left:10px;color:red};

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<section id="days"></section>
