jQuery .append 不适用于 $(document).ready

Question

这是toggleClass of parent div not changing with onClick的后续行动

在我的 HTML 布局中，我发现我需要在记录之后而不是之前生成 div #filters，因为我需要使用 PHP 来为每个状态构建按钮。这给了我使用 jQuery .append 将#filters 移动到记录上方的#move-filters-here 的想法。但是在我过滤一个状态后，过滤器出现在记录下方，.append 无法将#filters 移动到记录上方的#move-filters-here。

.append 不能与 (document).ready 一起使用吗？

有没有其他方法可以让.append 移动#filters？

.append 是否需要在 Onclick 功能后再次“触发”？

$(document).ready(function(){

$("#filters").append("#move-filters-here");

$('.state-button').on('click', function() {

  let _this = $(this);

  if (!_this.hasClass('active')) {

    $('.state-button.active, .record.active').removeClass('active');
    $('[data-state=' + _this.data('state') + ']').addClass('active');

  }

});

});

  .record {
    display: none;
}

.state-button {
    border: 2px solid #c2c2c2;
    padding: 5px;
    border-radius: 5px;
    margin: 0 10px 0 10px;
}

.state-button.active {
    border-color: red;
}

.record.active {
    display: block;
}

Answer 1

我假设您将 append 与 appendTo 混淆了。现在，您将文字文本 "#move-filters-here" 附加到 #filters 元素的内容中。如果您改用$('#filters').appendTo('#move-filters-here')，它会起作用。

$(document).ready(function(){

$("#filters").appendTo("#move-filters-here");

$('.state-button').on('click', function() {

  let _this = $(this);

  if (!_this.hasClass('active')) {

    $('.state-button.active, .record.active').removeClass('active');
    $('[data-state=' + _this.data('state') + ']').addClass('active');

  }

});

});

  .record {
    display: none;
}

.state-button {
    border: 2px solid #c2c2c2;
    padding: 5px;
    border-radius: 5px;
    margin: 0 10px 0 10px;
}

.state-button.active {
    border-color: red;
}

.record.active {
    display: block;
}

_{(或者，如果您出于某种原因特别想使用append，则需要以相反的方式进行操作，并且实际上将要附加的内容引用为 元素：$('#move-filters-here').append($('#filters')).)}

Answer 2

如果你想将#filter 附加到#move-filters-here 你可以这样做：

$("#move-filters-here").append($("#filters"));

反之亦然，您可以这样实现目标：

$("#filters").append("#move-filters-here");
