How can I submit a form with just the Enter key on a text input field, without having to add a submit button?
如何仅使用文本输入字段上的 Enter 键提交表单，而无需添加提交按钮？
I remember this worked in the past, but I tested it now and the form doesn't get submitted unless there's a submit-type input field inside it.
我记得这在过去有效，但我现在对其进行了测试，除非其中有一个提交类型的输入字段，否则表单不会被提交。

$("input").keypress(function(event) {
if (event.which == 13) {
event.preventDefault();
$("form").submit();
}
});

Change #form to your form's ID
将#form 更改为您表单的 ID
$('#form input').keydown(function(e) {
if (e.keyCode == 13) {
$('#form').submit();
}
});
Or alternatively
或者替代地
$('input').keydown(function(e) {
if (e.keyCode == 13) {
$(this).closest('form').submit();
}
});

Jay Gilford's answer will work, but I think really the easiest way is to just slap a display: none;on a submit button in the form.
杰伊吉尔福德的答案会起作用，但我认为最简单的方法是display: none;在表单中的提交按钮上打一个耳光。

@JayGuilford's answer is a good one, but if you don't want a JS dependency, you could use a submit element and simply hide it using display: none;.
@JayGuilford 的回答很好，但是如果您不想要 JS 依赖项，则可以使用 submit 元素并简单地使用display: none;.
