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');
});

使用jquery，你可以使用事件对象类型
jQuery(".element").on("click contextmenu", function(e){
if(e.type == "contextmenu") {
alert("Right click");
}
});
$.event.special.rightclick = {
bindType: "contextmenu",
delegateType: "contextmenu"
};
$(document).on("rightclick", "div", function() {
console.log("hello");
return false;
});

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...
}
});
$.event.special.rightclick = {
bindType: "contextmenu",
delegateType: "contextmenu"
};
$(document).on("rightclick", "div", function() {
console.log("hello");
return false;
});
从jQuery 1.1.3版本开始，事件。使事件正常化。keyCode和事件。charCode，这样就不必担心浏览器兼容性问题。关于event.which的文档
事件。它将分别给1、2或3个鼠标左、中、右按钮，这样:
$('#element').mousedown(function(event) {
switch (event.which) {
case 1:
alert('Left Mouse button pressed.');
break;
case 2:
alert('Middle Mouse button pressed.');
break;
case 3:
alert('Right Mouse button pressed.');
break;
default:
alert('You have a strange Mouse!');
}
});
