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');
});
当前回答
$.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");
});
其他回答
$.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!');
}
});
$.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");
});

<button id="btn">Click me with any mouse button: left, right, middle, ...</button>
<p id="message"></p>
<script>
let btn = document.querySelector('#btn');
// disable context menu when right-mouse clicked
btn.addEventListener('contextmenu', (e) => {
e.preventDefault();
});
// show the mouse event message
btn.addEventListener('mouseup', (e) => {
let msg = document.querySelector('#message');
switch (e.button) {
case 0:
msg.textContent = 'Left mouse button clicked.';
break;
case 1:
msg.textContent = 'Middle mouse button clicked.';
break;
case 2:
msg.textContent = 'Right mouse button clicked.';
break;
default:
msg.textContent = `Unknown mouse button code: ${event.button}`;
}
});
</script>
</body>
</html>
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。
