在“click to add another”事件中，此变量跟踪动态生成元素的索引：
var index = $(this).parent().parent().parent().parent().index();
正常工作，通过控制台日志记录证明。 index变量的最小值为1，没有最大值。我创建了原始html代码段的副本并将其附加到下面，并替换了输入名称（因此我可以运行jQuery验证）：
$("[name=officeAddressLine1]:last").replaceWith("<input type='text' data-
id='"+index+"' class='otherBusinessField' id='officeAddressLine"+index+"'
name='officeAddressLine"+index+"'>");
我连接index的值以使输入唯一，对于第一个动态生成的元素，我得到officeAddressLine2（这是正确的）但是之后的所有元素继续连接2 ，而不是3,4,5，......
我一直能够在点击事件中记录index的正确值。为什么在输入标记内部不会更新此值？
这是jQuery事件处理程序：
$('#BusinessBox').on('click', '.otherOffices [value=y]', function() {
if ($(this).parent().parent().parent().parent().next().attr('name') == 'otherOffice'){
return false;
}

答案 0 :(得分：1)
我发现有人不能使用jQuery的replaceWith()方法进行递归替换。替换索引1元素后，replaceWith()方法无法匹配（原始元素已被替换），因此迭代器运行一次，更改所有值，然后停止。
