要删除第一行,您可以将行的内容与这样的“a”进行比较….
$(document).ready(function(){
$("button").click(function(){
let row_len = $(".parent-row>.row").length;
$(".parent-row>.row").each(function(index, element){
if($(element).html().trim() == 'A') {
element.remove();
}
});
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="parent-row">
<div class="row">
A
</div>
</div>
<div class="parent-row">
<div class="row">

</div>
<div class="row">

</div>
</div>
<div class="parent-row">
<div class="row">

<div class="row">

</div>
<button type="button">Reset</button>
