我使用了以下答案中的代码:jquery clone form fields and increment id创建了我的表单的可克隆区域,除了“添加另一个”和“删除行”按钮外,所有区域都运行正常。
只有原始可克隆区域的“添加/删除”按钮才有效,因此下一个克隆区域的添加/删除按钮不会执行任何操作,这意味着您使用的第一行会令人困惑。
我真的看不出发生了什么。任何帮助将不胜感激!

jQuery:
var regex = /^(.*)(\d)+$/i;
var cloneIndex = $(".clonedInput").length;
$("button.clone").click(function(){

$(this).parents(".clonedInput").clone()
.appendTo("#accordion")
.attr("id", "clonedInput" + cloneIndex)
.find("*").each(function() {

var match = id.match(regex) || [];
if (match.length == 3) {

$("button.remove").click(function(){

对于动态添加的元素,请使用.on()
jQuery documentation .on()(适用于jQuery 1.7及更高版本)
在您发布的示例中,他们使用的是.live()
,适用于jQuery 1.7及更低版本。
在任何$(document).ready()函数之外添加它:
$(document).on('click', 'button.clone', function(){
...
});
通过执行此操作,事件处理程序将添加到document
,因此只要事件冒泡到源自button.clone
元素的事件,它就会触发该函数。因此,在加载页面后添加按钮时,即使在最初加载页面时它们不可用,它们仍会触发click事件。
如果您只使用$('button.clone').click(...)
,首次加载时页面上的按钮将触发点击事件。
