我使用 jquery 1.3.2。我在一页中有 2 个具有相同 ID 的相同提交按钮。按钮具有不同的表单 ID。

两个按钮具有相同的 id

<input type="submit" id="edit-submit-43" class="form-submit">

两种形式都有不同的id

<form action="/productxy" accept-charset="UTF-8" method="post" id="uc-product-kit-add-to-cart-form-43-1" class="ajax-cart-submit-form"></form>

如何获取被点击的按钮形式的id，而不是html中第一个按钮？

You don't show your JS, but assuming you are binding a common click handler to the buttons or a common submit handler to the forms you would use this in combination with DOM traversal methods:

$(".form-submit").click(function() {
    // assuming the button is actually inside its associated form:
    var parentFormID = $(this).closest("form").attr("id");
});

or:

$("form").submit(function() {
    var myId = this.id;
});

Within an event handler this will refer to the element that the event applied to.

And note that it is not valid to have duplicate IDs.

HTML 页面中的 ID 应该是唯一的。

将此更改为

<input type="submit" class="form-submit">

您可以完全删除idfor 按钮，因为它不是必需的

$('.form-submit').on('click', function() {

     var $form = $(this).closest('form');

     // this should give you the corresponding form 
     // in which the button is in

     var formId = $form.attr('id');
});
