在手风琴中折叠动态添加的选项卡

Question

这是一个示例。

$(function() {
        var icons = {
            header: "ui-icon-circle-arrow-e",
            headerSelected: "ui-icon-circle-arrow-s"
        };
        $( "#accordion" ).accordion({
            icons: icons,
            collapsible: true
        });
        $( "#header1" ).click(function(e) { return false;
            $( "#accordion" ).accordion( "option", "icons", false );
        });
});

$('#accordion .accClicked')
        .off('click')
    .click(function(){
        $(this).next().toggle('fast');
    });

    $('#add').click(function() {
       var $tab="<h3 id='header3' class='accClicked'><a href='#'>Section 3</a></h3><div>Bonjour Stackoverflow</div>";
       $('#accordion').append($tab);

    });

我可以添加一个新标签，但我不能折叠它。我搜索并发现我应该以某种方式更新 DOM，但我只是没有找到我该怎么做。

我可以简单地使用 jquery-ui 手风琴，但问题是，当您打开另一个选项卡时，它会自动关闭打开的选项卡，但我不需要。这是它的链接：JQuery-UI Accordion

您可以将点击重写变成一个函数，并为您添加的每个选项卡再次运行它：

$(function() {
    var icons = {
        header: "ui-icon-circle-arrow-e",
        headerSelected: "ui-icon-circle-arrow-s"
    };
    $("#accordion").accordion({
        icons: icons,
        collapsible: true
    });
    $("#header1").click(function(e) {
        return false;
        $("#accordion").accordion("option", "icons", false);
    });
});

// from here we change to:
function resetTabClick() {
    $('#accordion .accClicked')
        .off('click').click(function(){
            $(this).next().toggle('fast');
    });
}
resetTabClick();

$('#add').click(function() {
       var $tab="<h3 id='header3' class='accClicked'><a href='#'>Section 3</a></h3><div>Bonjour Stackoverflow</div>";
       $('#accordion').append($tab);

       resetTabClick();

 });

你很亲密。您只需要将选项卡的回调函数包装在一个函数中，以便在向 DOM 添加新选项卡时调用它。

此外，如果您希望新标签页最初关闭，请添加样式 display: none;。

$(function() {
    var icons = {
        header: "ui-icon-circle-arrow-e",
        headerSelected: "ui-icon-circle-arrow-s"
    };
    $("#accordion").accordion({
        icons: icons,
        collapsible: true
    });
    $("#header1").click(function(e) {
        return false;
        $("#accordion").accordion("option", "icons", false);
    });
});

function makeNewTab() {
    $('#accordion .accClicked')
        .off('click').click(function(){
            $(this).next().toggle('fast');
    });
}

$('#add').click(function() {
       var $tab="<h3 id='header3' class='accClicked'><a href='#'>Section 3</a></h3><div style='display:none;'>Bonjour Stackoverflow</div>";
       $('#accordion').append($tab);
       makeNewTab();

 });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<div id="accordion">
    <h3 id="header1" class="accClicked"><a href="#">Section 1</a></h3>
    <div> Good Morning Stackoverflow</div>
    <h3 id="header2" class="accClicked"><a href="#">Section 2</a></h3>
    <div>Buongiorno Stackoverflow</div>
    <h3 id="header3" class="accClicked"><a href="#">Section 3</a></h3>
    <div>Bonjour Stackoverflow</div>
</div>

<button id="add">
 Add tab
</button>

您需要将处理程序分配给新选项卡。检查这个

$(function() {
  var icons = {
    header: "ui-icon-circle-arrow-e",
    headerSelected: "ui-icon-circle-arrow-s"
  };
  $("#accordion").accordion({
    icons: icons,
    collapsible: true
  });
  $("#header1").click(function(e) {
    return false;
    $("#accordion").accordion("option", "icons", false);
  });
});

$('#accordion .accClicked')
  .off('click')
  .click(function() {
    $(this).next().toggle('fast');
  });

var i = 4;
$('#add').click(function() {
  var $tab = "<h3 id='header" + i + "' class='accClicked'><a href='#'>Section " + i + "</a></h3><div>Bonjour Stackoverflow</div>";
  $('#accordion').append($tab);
  $('#accordion .accClicked')
    .off('click')
    .click(function() {
      $(this).next().toggle('fast');
    });
  i++;
});
