单击选项卡时如何刷新选项卡内容？

Question

<div class="tab">
    <button class="tablinks" onclick="openMenu(event, 'Pending')">Pending</button>
    <button class="tablinks" onclick="openMenu(event, 'Completed')">Completed</button>
    <button class="tablinks" onclick="openMenu(event, 'Rejected')">Rejected</button>
    <button class="tablinks" onclick="openMenu(event, 'All')" id="defaultOpen">All</button>
</div>

<div id="Pending" class="tabcontent">
<%
 perform db selection pending records
%>

<div id="All" class="tabcontent">
<%
 perform db selection all records
%>

<script>
function openMenu(evt, Status) {
    var i, tabcontent, tablinks;
    tabcontent = document.getElementsByClassName("tabcontent");
    for (i = 0; i < tabcontent.length; i++) {
        tabcontent[i].style.display = "none";
    }
    tablinks = document.getElementsByClassName("tablinks");
    for (i = 0; i < tablinks.length; i++) {
        tablinks[i].className = tablinks[i].className.replace(" active", "");
        
    }
    document.getElementById(Status).style.display = "block";
    evt.currentTarget.className += " active";
}

// Get the element with id="defaultOpen" and click on it
document.getElementById("defaultOpen").click();
</script>

请参阅https://www.w3schools.com/howto/howto_js_tabs.asp示例。 我开发了一个标签来显示不同的状态内容。 我会执行记录状态更改，但是当某些记录状态发生更改时，我不知道如何刷新选项卡内容。

您可以使用 jQuery 做得更快更简单：

 <html> <body> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> </head> <div class="tab"> <button class="tablinks" data-val="Pending">Pending</button> <button class="tablinks" data-val="Completed">Completed</button> <button class="tablinks" data-val="Rejected">Rejected</button> <button class="tablinks active" data-val="All">All</button> </div> <div id="Pending" class="tabcontent"> <% perform db selection pending records %> <div id="All" class="tabcontent"> <% perform db selection all records %> <script> $(".tablinks").click(function(){ var val = $(this).attr("data-val"); if(val=="All") $('.tabcontent').show(); else { $('.tabcontent').hide(); $('#'+val).show(); $(".tablinks").removeClass("active"); $(this).addClass("active"); } }); </script> </body> </html>
