演示：您引用的代码有语法错误，我看不出$inputs有什么内容：
$(document).on('click', '#test-endpoint', function () {
var $form = $(this).parents('#test-form').first();
var $inputs = $form.find('input, textarea');
$inputs.each(function () {
alert("Got: " + this.tagName);
});
} // <================= Missing ); here
var $form = $(this).parents('#test-form').first();
var $inputs = $form.find('input, textarea');
$inputs.each(function ( idx, value) {
//The code never executed
});
你能分享html样本吗？它应该可以工作，你能展示你的html标记吗？作为一个侧面，而不是var$form=$this.parents'test-form'；可以替换为var$form=$'test-form'；若您有多个表单，那个么使用类而不是id，因为id必须是唯一的，那个么使用.nexist，比如var$form=$this.nexist'.testform'@Anton I发布了完整的html。如问题中所述，$inputs元素包含5个元素。是的，但我认为他可能是在控制台中手动检查$inputs，这似乎是可行的，因为他可能在加载页面时在控制台中检查。而且控制台奇怪地是半活动的，不像终端。
$(document).on('click', '#test-endpoint', function () {
var $form = $(this).parents('#test-form').first();
var $inputs = $form.find('input, textarea');
$inputs.each(function () {
alert("Got: " + this.tagName);
});
} // <================= Missing ); here
var $form = $(this).parents('#test-form').first();
var $inputs = $form.find('input, textarea');
$inputs.each(function ( idx, value) {
//The code never executed
});
