jQuery .append 不适用于 $(document).ready

Question

这是父级div的toggleClass的后续内容，不会随着onClick而改变

在我的 HTML 布局中，我发现我需要#filters在记录之后而不是之前生成 div，因为我需要使用 PHP 为每个状态构建按钮。.append这给了我使用 jQuery将 #filters 移动到记录上方的 #move-filters-here 的想法。但是，在我对某个状态进行筛选后，筛选器出现在记录下方，并且.append无法将 #filters 移动到记录上方的 #move-filters-here。

尚未.append使用（文档）。准备好了吗？

有没有不同的方法来.append移动#filters？

.appendOnclick 函数之后是否需要再次“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append对感到困惑appendTo。现在您正在将文字文本附加"#move-filters-here"到#filters元素的内容中。如果您使用$('#filters').appendTo('#move-filters-here')它，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想要append特别使用，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element : $('#move-filters-here').append($('#filters'))。）}
