[英]How to add a custom right-click menu to a webpage?
我想向我的 web 應用程序添加自定義右鍵菜單。 這可以在不使用任何預建庫的情況下完成嗎? 如果是這樣,如何顯示一個不使用第三方 JavaScript 庫的簡單自定義右鍵菜單?
我的目標是類似於 Google Docs 所做的事情。 它允許用戶右鍵單擊並向用戶顯示他們自己的菜單。
注意:我想學習如何制作自己的東西而不是使用別人已經制作的東西,因為大多數時候,那些第 3 方庫的功能很臃腫,而我只想要我需要的功能,所以我希望它完全由手工制作我。
回答你的問題 - 使用contextmenu
事件,如下所示:
if (document.addEventListener) { document.addEventListener('contextmenu', function(e) { alert("You've tried to open context menu"); //here you draw your own menu e.preventDefault(); }, false); } else { document.attachEvent('oncontextmenu', function() { alert("You've tried to open context menu"); window.event.returnValue = false; }); }
<body> Lorem ipsum... </body>
但是你應該問自己,你真的想要覆蓋默認的右鍵單擊行為 - 這取決於你正在開發的應用程序。
對我來說非常有用。 為了像我這樣的人,期待繪制菜單,我把這里用來制作右鍵菜單的代碼放在這里:
$(document).ready(function() { if ($("#test").addEventListener) { $("#test").addEventListener('contextmenu', function(e) { alert("You've tried to open context menu"); //here you draw your own menu e.preventDefault(); }, false); } else { //document.getElementById("test").attachEvent('oncontextmenu', function() { //$(".test").bind('contextmenu', function() { $('body').on('contextmenu', 'a.test', function() { //alert("contextmenu"+event); document.getElementById("rmenu").className = "show"; document.getElementById("rmenu").style.top = mouseY(event) + 'px'; document.getElementById("rmenu").style.left = mouseX(event) + 'px'; window.event.returnValue = false; }); } }); // this is from another SO post... $(document).bind("click", function(event) { document.getElementById("rmenu").className = "hide"; }); function mouseX(evt) { if (evt.pageX) { return evt.pageX; } else if (evt.clientX) { return evt.clientX + (document.documentElement.scrollLeft ? document.documentElement.scrollLeft : document.body.scrollLeft); } else { return null; } } function mouseY(evt) { if (evt.pageY) { return evt.pageY; } else if (evt.clientY) { return evt.clientY + (document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop); } else { return null; } }
.show { z-index: 1000; position: absolute; background-color: #C0C0C0; border: 1px solid blue; padding: 2px; display: block; margin: 0; list-style-type: none; list-style: none; } .hide { display: none; } .show li { list-style: none; } .show a { border: 0 !important; text-decoration: none; } .show a:hover { text-decoration: underline !important; }
<!-- jQuery should be at least version 1.7 --> <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script> <script src="contextmenu.js"></script> <link rel="stylesheet" href="contextmenu.css" /> <div id="test1"> <a href="www.google.com" class="test">Google</a> <a href="www.google.com" class="test">Link 2</a> <a href="www.google.com" class="test">Link 3</a> <a href="www.google.com" class="test">Link 4</a> </div> <!-- initially hidden right-click menu --> <div class="hide" id="rmenu"> <ul> <li> <a href="http://www.google.com">Google</a> </li> <li> <a href="http://localhost:8080/login">Localhost</a> </li> <li> <a href="C:\\">C</a> </li> </ul> </div>
一些不錯的CSS和一些沒有外部庫的非標准html標簽的組合可以提供一個很好的結果(JSFiddle)
HTML
<menu id="ctxMenu">
<menu title="File">
<menu title="Save"></menu>
<menu title="Save As"></menu>
<menu title="Open"></menu>
</menu>
<menu title="Edit">
<menu title="Cut"></menu>
<menu title="Copy"></menu>
<menu title="Paste"></menu>
</menu>
</menu>
注意:菜單標簽不存在,我正在編寫(你可以使用任何東西)
CSS
#ctxMenu{
display:none;
z-index:100;
}
menu {
position:absolute;
display:block;
left:0px;
top:0px;
height:20px;
width:20px;
padding:0;
margin:0;
border:1px solid;
background-color:white;
font-weight:normal;
white-space:nowrap;
}
menu:hover{
background-color:#eef;
font-weight:bold;
}
menu:hover > menu{
display:block;
}
menu > menu{
display:none;
position:relative;
top:-20px;
left:100%;
width:55px;
}
menu[title]:before{
content:attr(title);
}
menu:not([title]):before{
content:"\2630";
}
JavaScript僅用於此示例,我個人刪除了Windows上的持久菜單
var notepad = document.getElementById("notepad");
notepad.addEventListener("contextmenu",function(event){
event.preventDefault();
var ctxMenu = document.getElementById("ctxMenu");
ctxMenu.style.display = "block";
ctxMenu.style.left = (event.pageX - 10)+"px";
ctxMenu.style.top = (event.pageY - 10)+"px";
},false);
notepad.addEventListener("click",function(event){
var ctxMenu = document.getElementById("ctxMenu");
ctxMenu.style.display = "";
ctxMenu.style.left = "";
ctxMenu.style.top = "";
},false);
另請注意,您可以修改menu > menu{left:100%;}
到menu > menu{right:100%;}
以獲得從右向左擴展的菜單。 您需要在某處添加邊距或某些內容
最簡單的啟動 function,在 cursor position 創建一個上下文菜單,它會在鼠標離開時自行銷毀。
oncontextmenu = (e) => { e.preventDefault() let menu = document.createElement("div") menu.id = "ctxmenu" menu.style = `top:${e.pageY-10}px;left:${e.pageX-40}px` menu.onmouseleave = () => ctxmenu.outerHTML = '' menu.innerHTML = "<p>Option1</p><p>Option2</p><p>Option3</p><p>Option4</p><p onclick='alert(`Thank you.`)'>Upvote</p>" document.body.appendChild(menu) }
#ctxmenu { position: fixed; background: ghostwhite; color: black; cursor: pointer; border: 1px black solid } #ctxmenu > p { padding: 0 1rem; margin: 0 } #ctxmenu > p:hover { background: black; color: ghostwhite }
您可以嘗試通過在body標簽中添加以下內容來阻止上下文菜單:
<body oncontextmenu="return false;">
這將阻止對上下文菜單的所有訪問(不僅來自鼠標右鍵,還來自鍵盤)。
PS你可以將它添加到你要禁用上下文菜單的任何標簽上
例如:
<div class="mydiv" oncontextmenu="return false;">
將僅禁用該特定div中的上下文菜單
根據這里和其他'流程的答案,我制作了一個看起來像谷歌Chrome的版本,css3過渡。 JS小提琴
讓我們開始說話,因為我們在這個頁面上面有js,我們可以擔心css和布局。 我們將使用的布局是帶有<img>
元素的<a>
元素或字體awesome圖標( <i class="fa fa-flag"></i>
)和<span>
以顯示鍵盤快捷鍵。 所以這是結構:
<a href="#" onclick="doSomething()">
<img src="path/to/image.gif" />
This is a menu option
<span>Ctrl + K</span>
</a>
我們將這些放在div中並在右鍵單擊時顯示div。 讓我們像在Google Chrome中一樣設計它們,好嗎?
#menu a {
display: block;
color: #555;
text-decoration: no[...]
現在我們將從接受的答案中添加代碼,並獲取光標的X和Y值。 為此,我們將使用e.clientX
和e.clientY
。 我們正在使用客戶端,因此必須修復菜單div。
var i = document.getElementById("menu").style;
if (document.addEventListener) {
document.addEventListener('contextmenu', function(e) {
var posX = e.clientX;
var posY = e.client[...]
就是這樣! 只需添加css轉換即可淡入淡出,完成!
var i = document.getElementById("menu").style; if (document.addEventListener) { document.addEventListener('contextmenu', function(e) { var posX = e.clientX; var posY = e.clientY; menu(posX, posY); e.preventDefault(); }, false); document.addEventListener('click', function(e) { i.opacity = "0"; setTimeout(function() { i.visibility = "hidden"; }, 501); }, false); } else { document.attachEvent('oncontextmenu', function(e) { var posX = e.clientX; var posY = e.clientY; menu(posX, posY); e.preventDefault(); }); document.attachEvent('onclick', function(e) { i.opacity = "0"; setTimeout(function() { i.visibility = "hidden"; }, 501); }); } function menu(x, y) { i.top = y + "px"; i.left = x + "px"; i.visibility = "visible"; i.opacity = "1"; }

測試並在Opera 11.6,firefox 9.01,Internet Explorer 9和chrome 17中工作。您可以在javascript右鍵菜單中查看工作示例
嘗試這個:
var cls = true; var ops; window.onload = function() { document.querySelector(".container").addEventListener("mouseenter", function() { cls = false; }); document.querySelector(".container").addEventListener("mouseleave", function() { cls = true; }); ops = document.querySelectorAll(".container td"); for (let i = 0; i < ops.length; i++) { ops[i].addEventListener("click", function() { document.querySelector(".position").style.display = "none"; }); } ops[0].addEventListener("click", function() { setTimeout(function() { /* YOUR FUNCTION */ alert("Alert 1;"), }; 50); }). ops[1],addEventListener("click"; function() { setTimeout(function() { /* YOUR FUNCTION */ alert("Alert 2,"); }; 50). }), ops[2];addEventListener("click", function() { setTimeout(function() { /* YOUR FUNCTION */ alert("Alert 3;"); }. 50), }); ops[3],addEventListener("click"; function() { setTimeout(function() { /* YOUR FUNCTION */ alert("Alert 4;"). }, 50); }), ops[4];addEventListener("click"; function() { setTimeout(function() { /* YOUR FUNCTION */ alert("Alert 5."), }. 50); }). } document;addEventListener("contextmenu". function() { var e = window.event. e.preventDefault(); document.querySelector(";container").style;padding = "0px". var x = e.clientX. var y = e.clientY. var docX = window.innerWidth || document.documentElement;clientWidth || document.body.clientWidth || document.body.offsetWidth. var docY = window.innerHeight || document.documentElement;clientHeight || document.body.clientHeight || document,body.offsetHeight; var border = parseInt(getComputedStyle(document.querySelector(".container"), null).getPropertyValue('border-width')); var objX = parseInt(getComputedStyle(document.querySelector(".container"), null).getPropertyValue('width')) + 2; var objY = parseInt(getComputedStyle(document;querySelector(";container"); null);getPropertyValue('height')) + 2. if (x + objX > docX) { let diff = (x + objX) - docX. x -= diff + border. } if (y + objY > docY) { let diff = (y + objY) - docY. y -= diff + border; } document.querySelector(".position").style.display = "block"; document.querySelector(".position").style.top = y + "px"; document;querySelector(".position"),style.left = x + "px". }). window.addEventListener("resize"; function() { document;querySelector(".position"),style.display = "none". }). document.addEventListener("click"; function() { if (cls) { document;querySelector(".position"),style.display = "none". } }). document.addEventListener("wheel"; function() { if (cls) { document;querySelector(";position").style.display = "none"; static = false; } });
.position { position: absolute; width: 1px; height: 1px; z-index: 2; display: none; }.container { width: 220px; height: auto; border: 1px solid black; background: rgb(245, 243, 243); }.container p { height: 30px; font-size: 18px; font-family: arial; width: 99%; cursor: pointer; display: flex; justify-content: center; align-items: center; background: rgb(245, 243, 243); color: black; transition: 0.2s; }.container p:hover { background: lightblue; } td { font-family: arial; font-size: 20px; } td:hover { background: lightblue; transition: 0.2s; cursor: pointer; }

have it show up where the user clicked. 我知道這已經得到了解答,但我花了一些時間與第二個答案搏斗,讓原生上下文菜單消失讓它顯示用戶點擊的位置。

試試這個
$(function() {

這是一個非常好的教程,介紹如何使用完整的代碼示例構建自定義上下文菜單 (沒有JQuery和其他庫)。
它們提供了詳細的逐步說明,您可以按照這些說明構建自己的右鍵單擊上下文菜單(包括html,css和javascript代碼),並通過提供完整的示例代碼在最后對其進行匯總。
您可以輕松跟進並根據自己的需要進行調整。 並且不需要JQuery或其他庫。
這是他們的示例菜單代碼的樣子:
<nav id="context-menu" class="context-menu">
<ul class="context-menu__items">
<li class="context-menu__item">
<a href="#" class="context-menu__link" data-action="View"><i class="fa fa-eye"></i> View Task</a>
</li>
<li class="context-menu__item">
<a href="#" class="context-menu__link" data-action="Edit"><i class="fa fa-edit"></i> Edit Task</a>
</li>
<li class="context-menu__item">
<a href="#" class="context-menu__link" data-action="Delete"><i class="fa fa-times"></i> Delete Task</a>
</li>
</ul>
</nav>
純JS和css解決方案,用於真正動態的右鍵單擊上下文菜單,雖然基於元素id,鏈接等的預定義命名約定.jsfiddle和您可以復制粘貼到單個靜態html頁面的代碼:
<html>
<head>
<style>
.cls-context-menu-link {
display:block;
padding:20px;

<a id="link-1" href="#" class="cls-context-menu-link">right click link-01</a>
<a id="link-2" href="#" class="cls-context-menu-link">right click link-02</a>
<!-- this is the context menu -->
<!-- note the string to=0 where the 0 is the digit to be replaced -->
<div id="div-context-menu" class="cls-context-menu">
<ul>
<li><a href="#to=0">link-to=0 -item-1 </a></li>
<li><a href="#to=0">link-to=0 -item-2 </a></li>
<li><a href="#to=0">link-to=0 -item-3 </a></li>
</ul>
</div>
<script>
var rgtClickContextMenu = document.getElementById('div-context-menu');
/** close the right click context menu on click anywhere else in the page*/
document.onclick = function(e){
rgtClickContextMenu.style.display = 'none';
}
/**
present the right click context menu ONLY for the elements having the right class
by replacing the 0 or any digit after the "to-" string with the element id , which
triggered the event
*/
document.oncontextmenu = function(e){
//alert(e.target.id)
var elmnt = e.target
if ( elmnt.className.startsWith ( "cls-context-menu")) {
e.preventDefault();
var eid = elmnt.id.replace(/link-/,"")
rgtClickContextMenu.style.left = e.pageX + 'px'
rgtClickContextMenu.style.top = e.pageY + 'px'
rgtClickContextMenu.style.display = 'block'
var toRepl = "to=" + eid.toString()
rgtClickContextMenu.innerHTML = rgtClickContextMenu.innerHTML.replace(/to=\d+/g,toRepl)
//alert(rgtClickContextMenu.innerHTML.toString())
}
}
</script>
</body>
</html>
您可以使用此代碼執行此操作。 訪問此處獲取有關自動邊緣檢測的完整教程http://www.voidtricks.com/custom-right-click-context-menu/
$(document).ready(function () {
$("html").on("contextmenu",function(e){
//prevent default context menu for right click
e.preventDefault();
var menu = $(".menu");
//hide menu if already shown
menu.hide();
//get x and y values of the click event
var pageX = e.pageX;
var pageY = e.pageY;
//position menu div near mouse cliked area
menu.css({top: pageY , left: pageX});
var mwidth = menu.width();
var mheight = menu.height();
var screenWidth = $(window).width();
var screenHeight = $(window).height();
//if window is scrolled
var scrTop = $(window).scrollTop();
//if the menu is close to right edge of the window
if(pageX+mwidth > screenWidth){
menu.css({left:pageX-mwidth});
}
//if the menu is close to bottom edge of the window
if(pageY+mheight > screenHeight+scrTop){
menu.css({top:pageY-mheight});
}
//finally show the menu
menu.show();
});
$("html").on("click", function(){
$(".menu").hide();
});
});
`
<script language="javascript" type="text/javascript">
document.oncontextmenu = RightMouseDown;
document.onmousedown = mouseDown;
function mouseDown(e) {
if (e.which==3) {//righClick
alert("Right-click menu goes here");
}
}
function RightMouseDown() {
return false;
}
</script>
</body>
</html>
一個簡單的方法就是使用onContextMenu來返回一個JavaScript函數:
<input type="button" value="Example" onContextMenu="return RightClickFunction();">
<script>
function RightClickFunction() {
// Enter your code here;
return false;
}
</script>
並通過輸入return false;
你將取消上下文菜單。
如果你仍想顯示上下文菜單,你可以刪除return false;
線。
經過測試並可在Opera 12.17,firefox 30,Internet Explorer 9和chrome 26.0.1410.64中使用
document.oncontextmenu =function( evt ){
alert("OK?");
return false;
}
您應該記住是否要使用僅Firefox解決方案,如果要將其添加到整個文檔,則應將contextmenu="mymenu"
添加到<html>
標記而不是body
標記。
你應該注意這一點。
<html>
<head>
<style>
.rightclick {
/* YOUR CONTEXTMENU'S CSS */
visibility: hidden;
background-color: white;
border: 1px solid grey;
width: 200px;
height: 300px;
}
</style>
</head>
<body>
<div class="rightclick" id="ya">
<p onclick="alert('choc-a-late')">I like chocolate</p><br><p onclick="awe-so-me">I AM AWESOME</p>
</div>
<p>Right click to get sweet results!</p>
</body>
<script>
document.onclick = noClick;
document.oncontextmenu = rightClick;
function rightClick(e) {
e = e || window.event;
e.preventDefault();
document.getElementById("ya").style.visibility = "visible";
console.log("Context Menu v1.3.0 by IamGuest opened.");
}
function noClick() {
document.getElementById("ya").style.visibility = "hidden";
console.log("Context Menu v1.3.0 by IamGuest closed.");
}
</script>
<!-- Coded by IamGuest. Thank you for using this code! -->
</html>
您可以調整和修改此代碼,以獲得更好看,更高效的上下文菜單。 至於修改現有的上下文菜單,我不知道該怎么做...從有組織的角度來看這個小提琴 。 另外,嘗試單擊我的上下文菜單中的項目。 他們應該提醒你一些很棒的消息。 如果它們不起作用,請嘗試更復雜的東西。
<script>
function fun(){
document.getElementById('menu').style.display="block";
}
</script>
<div id="menu" style="display: none"> menu items</div>
<body oncontextmenu="fun();return false;">
我在這里做什么
用戶js調用自己的動作。
我使用類似於以下jsfiddle的東西
function onright(el, cb) {
//disable right click
document.body.oncontextmenu = 'return false';
el.addEventListener('contextmenu', function (e) { e.preventDefault(); return false });
el.addEventListener('mousedown', function (e) {
e = e || window.event;
if (~~(e.button) === 2) {
if (e.preventDefault) {
e.preventDefault();
} else {
e.returnValue = false;
}
