Jquery中Event对象属性小结

 那篇小说首要介绍了Jquery中Event对象属性的操作方法的下结论,特别的事无巨细,是篇特别正确的篇章,这里推荐给大家。

 

 

JS的Event对象是接触事件的时候传递给事件管理函数的贰个对象,这一个指标中设有触发事件的主题音讯。如:触发事件的事件源、键盘码(借使存在)等为主音信。

1、通过event.type获取事件的品类

 

代码如下:

<script>
$(function(){
$(“a”).click(function(event) {
alert(event.type);//获取事件类型
//return false;//阻止链接跳转
event.preventDefault();
});
})
</script>

 

2、获取事件指标的属性值
html部分代码如下:

 

代码如下:

<body>
<a href=’ me .</a>
</body>

 

 

代码如下:

<script>
$(function(){
$(“a[href=) {
alert(event.target.href);//获取触发事件的<a>成分的href属性值
return false;//阻止链接跳转
});
})
</script>

 

能够获得到属性href的值为‘

3、获取鼠标对应的坐标值x与y

 

代码如下:

<script>
$(function(){
$(“a”).click(function(e) {
alert(“Current mouse position: ” + e.pageX + “, ” + e.pageY
);//获取鼠标当前相对于页面包车型客车坐标
return false;//阻止链接跳转
});
})
</script>

 

此地传递的参数名不自然非若是event,能够是即兴的称呼,只要后边的对峙应就足以。暗中同意传入的值为event。假使你不给参数的话,就能够默许传入一个叫event的参数。

4、which属性能够收获相应的风浪对应的值
which 属性提醒按了哪个键或按钮。

 

代码如下:

<script>
$(function(){
$(“a”).mousedown(function(e){
alert(e.which) // 1 = 鼠标左键 left; 2 = 鼠标中键; 3 = 鼠标右键
return false;//阻止链接跳转
})
})
</script>

 

有关什么获取三个键在Javascript中的Keycode值,可以参谋:

 

代码如下:

keycode 8 = BackSpace BackSpace
keycode 9 = Tab Tab
keycode 12 = Clear
keycode 13 = Enter
keycode 16 = Shift_L
keycode 17 = Control_L

如上是js中的键值参照他事他说加以考察,当中相比较根本的有13(enter),32(空格),27(ESC),16(Shift),17(Ctrl),18(Alt)。

更加多的值能够透过下边包车型地铁jQuery来取得:

 

代码如下:

<script>
$(function(){
$(“input”).keyup(function(e){//获取keyup时间的值
alert(e.which);
})
})
</script>

那篇文章首要介绍了Jquery中Event对象属性的操作方法的下结论,特其他事无巨细,是篇极其科学的稿子,这里推荐给大家…

Jquery中伊芙nt对象属性小结,jqueryevent

 JS的Event对象是触发事件的时候传递给事件管理函数的二个对象,那么些指标中留存触发事件的主干新闻。如:触发事件的事件源、键盘码(纵然存在)等着力音讯。

1、通过event.type获取事件的品种

复制代码 代码如下:

<script>
$(function(){
    $(“a”).click(function(event) {
      alert(event.type);//获取事件类型
      //return false;//阻止链接跳转
      event.preventDefault();
    });
})
</script>

2、获取事件目的的属性值
html部分代码如下:

复制代码 代码如下:

<body>
<a href=’ me .</a>
</body>

复制代码 代码如下:

<script>
$(function(){
    $(“a[href=) {
     
alert(event.target.href);//获取触发事件的<a>成分的href属性值
      return false;//阻止链接跳转
    });
})
</script>

能够赢获得属性href的值为‘

3、获取鼠标对应的坐标值x与y

复制代码 代码如下:

<script>
$(function(){
    $(“a”).click(function(e) {
      alert(“Current mouse position: ” + e.pageX + “, ” + e.pageY
);//获取鼠标当前相对于页面的坐标
      return false;//阻止链接跳转
    });
})
</script>

此间传递的参数名不确定非如若event,可以是大肆的名称,只要后边的相对应就足以。私下认可传入的值为event。假如您不给参数的话,就能够私下认可传入三个叫event的参数。

4、which属性能够得到相应的事件对应的值
which 属性提示按了哪个键或开关。

复制代码 代码如下:

<script>
$(function(){
    $(“a”).mousedown(function(e){
        alert(e.which)  // 1 = 鼠标左键 left; 2 = 鼠标中键; 3 =
鼠标右键
        return false;//阻止链接跳转
    })
})
</script>

关于如何获得多个键在Javascript中的Keycode值,能够参照:

keycode 18 = Alt_L
keycode 19 = Pause
