我正在克隆一个 HTML 块，然后将其附加到一个 div 中。

var part = $('#parts_tpl').clone();
$('#parts_tpl').after(part);

HTML 包含一个表单，出于某种原因，选择框不会更新新克隆的 HTML 中的值。如果我尝试更新原始选择框值，它会起作用。我只是不使用新克隆的表单。

我确保新创建的选择框具有唯一的 id、名称等。这就是我的做法：

// increment ids and names for select tags
    $('#' + content.attr('id')).find('select').each(function() {
        var id = $(this).attr('id') + partID;
        var name = $(this).attr('name') + partID;

        if ($(this).attr('id')) { $(this).attr('id', id); }
        if ($(this).attr('name')) { $(this).attr('name', name); }
    });

这是我的 HTML 的样子：

<div class="parts" id="parts_tpl">
   <fieldset>
      <label>Part Specifications</label>
      <a href="#" class="btn removePartBtn" id="removePartBtn" style="float: right; display: none;">Remove Part</a>

好吧，事实证明。我正在使用一个名为Uniform的插件。Uniform 在克隆选择时效果不佳。这是我必须做的来修复它。

// fix uniform to update properly on cloned elements
$('select').change(function() { 
    $.uniform.update('#' + $(this).attr('id')); 
});

我也遇到了统一和克隆的问题，我的复选框在克隆后表现得很奇怪，我解决它的方法是使用统一的“恢复”，它基本上从所有元素中删除统一，然后我克隆了我所拥有的克隆，并重新应用制服。我想如果我愿意的话，我可以只对单个克隆源元素使用还原，而不是从所有元素中删除（没有检查）。

所以它最终看起来像这样：

$.uniform.restore($( "select, input:checkbox, input:radio, input:file")); // remove uniform effects
var clonedItem = $("#originalItem").clone(); // clone and add
$("body").append(clonedItem);
$( "select, input:checkbox, input:radio, input:file").uniform(); // restore uniform

希望这可以帮助某人。
