右击是Javascript事件吗?如果是,我该如何使用它?


当前回答

是的,虽然w3c说右键点击可以通过点击事件检测到,onClick不是通过在通常的浏览器中单击右键触发的。

事实上,右键只触发onMouseDown onMouseUp和onContextMenu。

因此,您可以将“onContextMenu”视为右键单击事件。它是一个HTML5.0标准。

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>

您可以使用事件窗口。Oncontextmenu,例如:

窗口。Oncontextmenu = function () { alert(右键) } <h1>请右键点击这里!< / h1 >

是的,它是!

function doSomething(e) {
    var rightclick;
    if (!e) var e = window.event;
    if (e.which) rightclick = (e.which == 3);
    else if (e.button) rightclick = (e.button == 2);
    alert('Rightclick: ' + rightclick); // true or false
}

没有,但是你可以检测到在"onmousedown"事件中使用了什么鼠标按钮…然后从那里判断它是否是一个“右键”。

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)...

在本章中,我们将详细介绍鼠标事件及其属性……
