Javascript implements right-click mouse customization menu
JS屏蔽鼠标右键的两种方法，比较常用的一个JS小功能，用上这个代码后，浏览者在访问你网页的时候就不能点击右键了，点了也不会弹出右键菜单，本功能最好不要用的太多哦，有时候用户会反感的。
代码如下:
<html>
<head>
<title>屏蔽鼠标右键</title>
</head>
<body oncontextmenu=self.event.returnvalue=false>
第一种方法：在body标签里加上oncontextmenu=self.event.returnvalue=false;
<br>
<script language="javascript">
<!--
function document.oncontextmenu()
{
return false;
}
function nocontextmenu()
{
if(document.all) {
event.cancelBubble=true;
event.returnvalue=false;
return false;
}
}
-->
</script>
第二种方法：在body里加入onmousedown="rclick()" oncontextmenu= "nocontextmenu()"
<br>
<script language="javascript">
<!--
function rclick()
{
if(document.all) {
if (event.button == 2){
event.returnvalue=false;
}
}
}
-->
</script>
<br>详细情况请查看代码。<br>
<br>现在点击你的鼠标右键，不起作用了。
</body>
</html>以上就是本文的全部内容，希望对大家的学习有所帮助。
,两种JS实现屏蔽鼠标右键的方法,
"
在Web端，通常是不需要右键菜单，各个浏览器也有自己的右键菜单。但是对于一些特殊的网页，是需要右键菜单来增加用户体验的，比如百度音乐，QQ邮箱，相信大家都在Web端使用过右键菜单了，现在来分享一下如何实现，比较简单。
运行代码：
window.onload = function() {
document.oncontextmenu = block;
document.body.onmouseup = function(event) {
if (!event) event = window.event;
if (event.button == 2) {
var x = event.pageX || event.clientX;
var y = event.pageY || event.clientY;
document.getElementById("contextMenu").style.left = x "px";
document.getElementById("contextMenu").style.top = y "px";
document.getElementById("contextMenu").style.display = "block";
}
}
//阻止事件冒泡
document.getElementById("contextMenu").onclick = function(event) {
event.stopPropagation();
}
//点击其他地方隐藏
document.onclick = function() {
document.getElementById("contextMenu").style.display = "none";
}
for (var i = 0; i < getElementsByClassName("contextMenuItem").length; i ) {
getElementsByClassName("contextMenuItem")[i].onclick = function(event) {
event = event ? event : window.event
var target = event.srcElement ? event.srcElement : event.targe;
document.getElementById("contextMenu").style.display = "none";
//alert("您点击了： " target.innerHTML);
}
}
}
function block(event) {
if (window.event) {
event = window.event;
event.returnValue = false;
} else event.preventDefault();
}
//兼容IE不支持getElementsByClassName
function getElementsByClassName(className, root, tagName) {
if (root) {
root = typeof root == "string" ? document.getElementById(root) : root;
} else {
root = document.body;
}
tagName = tagName || "*";
if (document.getElementsByClassName) {
return root.getElementsByClassName(className);
} else {
var tag = root.getElementsByTagName(tagName);
var tagAll = [];
for (var i = 0; i < tag.length; i ) {
for (var j = 0, n = tag[i].className.split(" "); j < n.length; j ) {
if (n[j] == className) {
tagAll.push(tag[i]);
break;
}
}
}
return tagAll;
}
