使用jQuery从变量中删除HTML div

Question

我有一些json响应，我需要根据主题从json响应中删除一些匹配的元素。

检查jQuery代码从json响应中删除HTML元素的位置。

我尝试了remove（）方法，但是在这里没有用。 HTML Strcture看起来像这样，一旦匹配主题后，我想基于主题删除匹配的元素，然后从响应变量中删除匹配的元素：

<div class="mailleft_cover" data-abc="New Whatsapp Chat Message From: 91956953****@c.us">
    <div class="checkbox">
        <label>
            <input type="checkbox" class="mailUid" value="384">
        </label>
        <span class="glyphicon glyphicon-star-empty single_move_starred"></span>
    </div>

    <a href="#" data-uid="384" data-mailbox="INBOX" class="list-group-item wml_get_single_mail active">
        <span class="hide"></span>
        <span class="email"><img alt="icon" class="whatsppp-icon" src="http://54.161.237.21.xip.io/wp-content/plugins/box_26_12_18/images/whatsppp.png"><span class="personcontact"> 91956953****</span></span>

        <br>
        <span class="last-msg c2">again next message</span>
        <span class="subject hide"><em>New Whatsapp Chat Message From: 91956953****@c.us</em></span>
        <span class="badge">Feb 19</span>
    </a>
    <span class="show_drop"><i class="glyphicon glyphicon-chevron-right"></i></span>        
</div>
<div class="mailleft_cover">
    <div class="checkbox">
        <label>
            <input type="checkbox" class="mailUid" value="378">
        </label>
        <span class="glyphicon glyphicon-star-empty single_move_starred"></span>
    </div>

    <a href="#" data-uid="378" data-mailbox="INBOX" class="list-group-item wml_get_single_mail">
        <span class="hide"></span>
        <span class="email">developer.odz@gmail.com</span>

        <span class="message-icon"><span class="glyphicon glyphicon-envelope"></span></span><br>
        <span class="last-msg c2"><em>Jinny the jin</em></span>
        <span class="subject hide"><em>Jinny the jin</em></span>
        <span class="badge">Feb 19</span>
    </a>

</div>

jQuery代码从json响应中获取数据，然后过滤数据并在此之后检查与dom元素匹配的主题，我想从response.htmldata变量中删除匹配的元素：

 jQuery(response.htmldata).filter('.mailleft_cover').each(function(i) {
    var subject = jQuery(this).attr('data-abc');
    var current_div = jQuery(this).html();
    jQuery(document).find('.mailleft_cover').each(function(i) {            
        var domElem = $(this).find('a > span.subject em')[0];
        var domElem = jQuery(domElem).text();
        var activeElem = false;
        ifnew = false;
        if (domElem == subject) {               
            var this_ = jQuery(this);
            if (jQuery(this_[0]).find('a').hasClass('active')) {
                console.log('Logging this elem: ', this_[0]);
                activeElem = true;
            }
            var test = jQuery(this).html(current_div);                
            if (activeElem) {
                jQuery(test[0]).find('a').trigger('click');                    
            }
            //Now remove current div from response.htmldata
            return false;
        } else {
            ifnew = true;
            console.log('subject not matched');
            //var test = jQuery(this).html(current_div);                            
        }

    });
});
