无论单击哪个按钮，我只想获取该按钮的ID.

Whichever may be the button click, I just want to get id of that button.

$(function () {

        var id = $(this).attr('id');

        alert(id);
})

$("input").click(function (event) {
        var urlid = $(this).attr('id')

问题

$("input")->选择带有标签input的元素，例如. <input type="text"/>而不是<button>标记.

$("input") --> selects elements with tag input eg. <input type="text"/> but not <button> tag .
