menuitem和contextmenu crossbrowser兼容性 [英] menuitem and contextmenu crossbrowser compatibility
问题描述
contextmenu
。 function addFullScreenMenu(){
var menu = document.createElement('menu');
var item = document.createElement('menuitem');
menu.setAttribute('id','fsmenu');
menu.setAttribute('type','context');
item.setAttribute('label','Fullscreen');
item.addEventListener('click',function(e){
if(window.fullScreen){
document.body.mozCancelFullScreen();
} else {
document.body.mozRequestFullScreen();
}
});
menu.appendChild(item);
document.body.appendChild(menu);
document.body.setAttribute('contextmenu','fsmenu');
问题:工作于 firefox
但在> GoogleChrome(版本21.0.1180.81)中失败
。
应该做些什么修正,在 Googlechrome
问题2:捕获右键单击事件使用
EventListener
代码:
< script type =text / javascript>
if(document.addEventListener){
document.addEventListener('contextmenu',function(e){
alert(您试图打开上下文菜单); //获取提醒在firefox和googlechrome
e.preventDefault();
},false);
} else {
document.attachEvent('oncontextmenu',function(){
alert(您试图打开上下文菜单); //在Internet Explorer中获取警报
window.event.returnValue = false;
});
}
< / script>
问题:EventListener for right click not working in Internet Explorer(Version 9)
更新:我可以解决problem2表单Phx答案。需要针对problem1的解决方案。
和 .mozCancelFullScreen();
。 全屏API未完全实现但在许多网页浏览器中。如果你想使用它,我建议使用polyfill。这是一个很好的: https://github.com/sindresorhus/screenfull.js/ 。 (它实际上是一个包装,但它可以完成这项工作。)
包含polyfill后,您的代码将如下所示:
function addFullScreenMenu(){
var menu = document.createElement('menu');
var item = document.createElement('menuitem');
menu.setAttribute('id','fsmenu');
menu.setAttribute('type','context');
item.setAttribute('label','Fullscreen');
item.addEventListener('click',function(e){
if(screenfull.enabled){
screenfull.toggle(this);
}
else {
alert(此浏览器不支持Fullscreen API。);
}
});
menu.appendChild(item);
document.body.appendChild(menu);
document.body.setAttribute('contextmenu','fsmenu');
}
Problem 1: I had made my own contextmenu
using the following piece of code.
function addFullScreenMenu () {
var menu = document.createElement('menu');
var item = document.createElement('menuitem');
menu.setAttribute('id', 'fsmenu');
menu.setAttribute('type', 'context');
item.setAttribute('label', 'Fullscreen');
item.addEventListener('click', function (e) {
if (window.fullScreen) {
document.body.mozCancelFullScreen();
} else {
document.body.mozRequestFullScreen();
}
});
menu.appendChild(item);
document.body.appendChild(menu);
document.body.setAttribute('contextmenu', 'fsmenu');
}
Issue: Works in firefox
but fails in GoogleChrome(Version 21.0.1180.81)
.
What corrections should be done so that it does not fail in Googlechrome
Problem 2: Capturing right click event using EventListener
Code:
<script type="text/javascript">
if (document.addEventListener) {
document.addEventListener('contextmenu', function(e) {
alert("You've tried to open context menu"); //gets alerted in firefox and googlechrome
e.preventDefault();
}, false);
} else {
document.attachEvent('oncontextmenu', function() {
alert("You've tried to open context menu");//gets alerted in Internet explorer
window.event.returnValue = false;
});
}
</script>

Update: I can solve problem2 form Phx answer . Need solution for problem1.
You are using Mozilla-specific functions, namely .mozRequestFullScreen();
and .mozCancelFullScreen();
.
The fullscreen API isn't fully implemented yet in many web browsers. If you want to use it, I recommend using a polyfill. Here's a good one: https://github.com/sindresorhus/screenfull.js/. (It's actually a wrapper, but it will do the job.)
With the polyfill included, your code would look like:
function addFullScreenMenu () {
var menu = document.createElement('menu');
var item = document.createElement('menuitem');
menu.setAttribute('id', 'fsmenu');
menu.setAttribute('type', 'context');
item.setAttribute('label', 'Fullscreen');
item.addEventListener('click', function (e) {
if (screenfull.enabled) {
screenfull.toggle(this);
}
else {
alert("This browser doesn't support Fullscreen API.");
}
});
menu.appendChild(item);
document.body.appendChild(menu);
document.body.setAttribute('contextmenu', 'fsmenu');
}
