javascript - Jquery 选择器 - 多个项目

Question

假设我有两个 jquery 选择:

var txtA = $('#txtA');
var txtB = $('#txtB');

为了附加相同的事件函数，这是最简洁的方法吗，还是我错过了一段明显的语法或 jquery 技巧？

$(jQuery.merge(txtA , txtB )).click(function () { alert('hello'); });

谢谢。

Answer 1

.add()应该这样做(前提是您已经填充了 txtA 和 txtB 并希望重用这些选择。):

txtA.add(txtB).click(function () {
    alert('hello');
});

Given a jQuery object that represents a set of DOM elements, the .add() method constructs a new jQuery object from the union of those elements and the ones passed into the method. The argument to .add() can be pretty much anything that $() accepts, including a jQuery selector expression, references to DOM elements, or an HTML snippet.
