右击是Javascript事件吗?如果是,我该如何使用它?
当前回答
最简单的右击方式是使用
$('classx').on('contextmenu', function (event) {
});
然而,这不是跨浏览器的解决方案,浏览器的行为不同,特别是firefox和IE。我推荐下面的跨浏览器解决方案
$('classx').on('mousedown', function (event) {
var keycode = ( event.keyCode ? event.keyCode : event.which );
if (keycode === 3) {
//your right click code goes here
}
});

这是最简单的方法,它可以在所有浏览器上运行,除了应用程序web视图,如(CefSharp铬等…). 我希望我的代码能帮助到你,祝你好运!
const contentToRightClick=document.querySelector("div#contentToRightClick"); //const contentToRightClick=window; //If you want to add it into the whole document contentToRightClick.oncontextmenu=function(e){ e=(e||window.event); e.preventDefault(); console.log(e); return false; //Remove it if you want to keep the default contextmenu } div#contentToRightClick{ background-color: #eee; border: 1px solid rgba(0,0,0,.2); overflow: hidden; padding: 20px; height: 150px; } <div id="contentToRightClick">Right click on the box !</div>
正如其他人所提到的,可以通过通常的鼠标事件(鼠标下拉、鼠标上拉、单击)来检测鼠标右键。但是,如果您在弹出右键菜单时寻找触发事件,那么就找错地方了。右键单击/上下文菜单也可以通过键盘(shift+F10或上下文菜单键在Windows和一些Linux)访问。在这种情况下,你正在寻找的事件是oncontextmenu:
window.oncontextmenu = function ()
{
showCustomMenu();
return false; // cancel default menu
}
至于鼠标事件本身,浏览器为事件对象设置了一个属性,可以从事件处理函数中访问:
document.body.onclick = function (e) {
var isRightMB;
e = e || window.event;
if ("which" in e) // Gecko (Firefox), WebKit (Safari/Chrome) & Opera
isRightMB = e.which == 3;
else if ("button" in e) // IE, Opera
isRightMB = e.button == 2;
alert("Right mouse button " + (isRightMB ? "" : " was not") + "clicked!");
}
窗口。oncontextmenu - MDC
下面的代码使用jQuery生成一个基于默认鼠标下拉和鼠标上拉事件的自定义右键单击事件。 它考虑到以下几点:
鼠标悬停时触发 仅当鼠标按下之前的同一元素时触发 这段代码特别适用于JFX Webview(因为上下文菜单事件不会在那里触发) 当键盘上的上下文菜单键被按下时,它不会触发(就像on('contextmenu',…)的解决方案一样)
$(function () { // global rightclick handler - trigger custom event "rightclick" var mouseDownElements = []; $(document).on('mousedown', '*', function(event) { if (event.which == 3) { mouseDownElements.push(this); } }); $(document).on('mouseup', '*', function(event) { if (event.which == 3 && mouseDownElements.indexOf(this) >= 0) { $(this).trigger('rightclick'); } }); $(document).on('mouseup', function() { mouseDownElements.length = 0; }); // disable contextmenu $(document).on('contextmenu', function(event) { event.preventDefault(); }); }); // Usage: $('#testButton').on('rightclick', function(event) { alert('this was a rightclick'); }); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <button id="testButton">Rightclick me</button>
您可能想尝试以下属性:
按钮- (caniuse); Which - (caniuse)(弃用)。
function onMouseDown(e)
{
if (e.which === 1 || e.button === 0)
{
console.log('Left mouse button at ' + e.clientX + 'x' + e.clientY);
}
if (e.which === 2 || e.button === 1)
{
console.log('Middle mouse button at ' + e.clientX + 'x' + e.clientY);
}
if (e.which === 3 || e.button === 2)
{
console.log('Right mouse button at ' + e.clientX + 'x' + e.clientY);
}
if (e.which === 4 || e.button === 3)
{
console.log('Backward mouse button at ' + e.clientX + 'x' + e.clientY);
}
if (e.which === 5 || e.button === 4)
{
console.log('Forward mouse button at ' + e.clientX + 'x' + e.clientY);
}
}
window.addEventListener("mousedown", onMouseDown);
document.addEventListener("contextmenu", function(e)
{
e.preventDefault();
});

操作系统
On Windows and Linux there are modifier keys Alt, Shift and Ctrl. On Mac there’s one more: Cmd, corresponding to the property metaKey... Even if we’d like to force Mac users to Ctrl+click – that’s kind of difficult. The problem is: a left-click with Ctrl is interpreted as a right-click on MacOS, and it generates the contextmenu event, not click like Windows/Linux. So if we want users of all operating systems to feel comfortable, then together with ctrlKey we should check metaKey. For JS-code it means that we should check if (event.ctrlKey || event.metaKey)...

是的,它是一个javascript鼠标下拉事件。有一个jQuery插件也可以做到这一点
