Jquery中Event对象属性小结

首先,声明转载的网址:破洛洛   http://www.poluoluo.com/jzxy/201504/353727.html


JS的Event对象是触发事件的时候传递给事件处理函数的一个对象,这个对象中存在触发事件的基本信息。如:触发事件的事件源、键盘码(如果存在)等基本信息。

1、通过event.type获取事件的类型

2、获取事件目标的属性值
html部分代码如下: 可以获取到属性href的值为‘http://google.com'。

代码如下:

代码如下:

3、获取鼠标对应的坐标值x与y

这里传递的参数名不一定非要是event,可以是任意的名称,只要后面的相对应就可以。默认传入的值为event。如果你不给参数的话,就会默认传入一个叫event的参数。

代码如下:

4、which属性可以获取相应的事件对应的值

which 属性指示按了哪个键或按钮。

代码如下:

关于如何得到一个键在Javascript中的Keycode值,可以参考:

代码如下:

以上是js中的键值参考,其中比较重要的有13(enter),32(空格),27(ESC),16(Shift),17(Ctrl),18(Alt)。

更多的值可以通过下面的jQuery来获取:
