如何使用jQuery获得鼠标点击按钮?
$('div').bind('click', function(){
alert('clicked');
});
这是由右键和左键点击触发的,有什么方法可以捕捉到鼠标右键点击?如果存在以下内容,我会很高兴:
$('div').bind('rightclick', function(){
alert('right mouse button is pressed');
});

$.fn.rightclick = function(func){
$(this).mousedown(function(event){
if(event.button == 2) {
var oncontextmenu = document.oncontextmenu;
document.oncontextmenu = function(){return false;};
setTimeout(function(){document.oncontextmenu = oncontextmenu;},300);
func(event);
return false;
}
});
};
$('.item').rightclick(function(e){
alert("item");
});
事件。which === 1确保它是一个左键点击(当使用jQuery时)。
但您还应该考虑修改器键:ctrlcmdshiftalt
如果你只对捕捉简单的、未修改的左键点击感兴趣,你可以这样做:
var isSimpleClick = function (event) {
return !(
event.which !== 1 || // not a left click
event.metaKey || // "open link in new tab" (mac)
event.ctrlKey || // "open link in new tab" (windows/linux)
event.shiftKey || // "open link in new window"
event.altKey // "save link as"
);
};
$('a').on('click', function (event) {
if (isSimpleClick(event)) {
event.preventDefault();
// do something...
}
});
通过查看鼠标事件的事件对象的属性,你可以很容易地知道按下了哪个鼠标按钮:
/*
1 = Left mouse button
2 = Centre mouse button
3 = Right mouse button
*/
$([selector]).mousedown(function(e) {
if (e.which === 3) {
/* Right mouse button was clicked! */
}
});

对于那些不知道是否应该使用事件的人。在普通JS或Angular中:现在已弃用,所以更喜欢使用event。按钮。
注意:使用此方法和(mousedown)事件:
左键按关联到1 右键单击与2关联 滚动按钮按下与4相关联
and (mouseup)事件将不会返回相同的数字,而是0。
