我成功地设法创建了一个表单，可以将新行添加到由两个表单集组成的表单中。
出现新字段，我可以输入并提交数据。但是在第一次提交后，这些字段显示为empthy。如果我重新输入数据，则值将正确传递。所以我在add - 脚本的末尾添加了一个重新验证，并且表单通过了。但是没有数据被添加到模型中，所以我认为数据是在第一个approche中没有传递的。
感谢您的帮助！

更新
所以我发现了问题：
function updateElementIndex(el, prefix, ndx) {
var id_regex = new RegExp('(' + prefix + '-\\d+-)');
var replacement = prefix + '-' + ndx + '-';
if ($(el).attr("for")) $(el).attr("for", $(el).attr("for").replace(id_regex,
replacement));
if (el.id) el.id = el.id.replace(id_regex, replacement);
if (el.name) el.name = el.name.replace(id_regex, replacement);
}
不更新ID或名称。然而，“For”已更新。如果我纠正这个问题，一切都会变得很好。
那么我该如何解决这个问题呢？
答案 0 :(得分：0)
此行帽将替换为：
$(row).children().children().each(function () {
updateElementIndex(this, prefix, formCount);
$(this).val("");
$(row).children().children().children().each(function () {
updateElementIndex(this, prefix, formCount);
$(this).val("");
由于HTML生成了一个带有3个嵌套元素的div
<div id="div_id_attr-0-prueftext_attributiv" class="form-group">
<label class="control-label " for="id_attr-0-prueftext_attributiv">
</label>
<div class="controls ">
<input id="id_attr-1-prueftext_attributiv" class="textinput
extInput form-control" type="text" name="attr-
1-prueftext_attributiv" maxlength="64"></input>
</div>
</div>
使用两个.children（）替换只能达到标签和控制而不是输入。
