在Firefox和Chrome中重写快捷键 [英] Overriding shortcut keys in firefox and chrome

问题描述

我有一个脚本，应该打开一个网页的一部分，并保存更改Ctrl + n和Ctrl + s repectivly我得到它在IE浏览器中工作，但似乎并没有在Firefox和铬。任何想法？

我的搭车功能。

  function prevent （e）
 {
 try {e.stopPropagation（）;} catch（ex）{} 
 try {e.preventDefault（）} catch（ex）{} 
 try { if（e.preventDefault）
 e.preventDefault（）; 
 else {
 e.cancelBubble = true; 
 e.returnValue = false; 
 e.keyCode = 0; 
}} catch（ex）{} 
} 
  

解决方案

我看到了同样的问题。有些浏览器不允许你捕捉某些快捷方式。看看这个 https://stackoverflow.com/a/7296303/1366887

一些组合键在Chrome 4中被滥用，而在Chrome 3中则没有。请看这里： https://groups.google.com/a/chromium.org/forum/?fromgroups=#!topic/chromium-bugs/Ntc1byZXHfU

这里是Javascript：

  $（window）.keydown （event（event）{
 if（event.ctrlKey& event.keyCode == 84）{
 console.log（Hey！Ctrl + T event captured！）; 
 event.preventDefault（）; 
} 
 if（event.ctrlKey&& event.keyCode == 83）{
 console.log（Hey！Ctrl + S event captured！ ）; 
 event.preventDefault（）; 
} 
}）; 
  

我曾经使用过这么多次，

下面是另外一个可以查看的资源： http://unixpapa.com/js/key.html

没有Jquery：

< （e.ctrlKey& e.keyCode =='S'.charCodeAt（0））{
（$ c $） e.preventDefault（）;
//您的储蓄码


code $ $ $ $ $ $ $ $ $ $ $ $ $它的 JSFIDDLE 正在工作。

I have a script that is supposed to open a section of a web page and save changes on Ctrl + n and Ctrl + s repectivly I got it working in IE but it doesn't seem to work in firefox and chrome. Any ideas?

My over ride function.

function prevent(e)
{
try{e.stopPropagation();}catch(ex){}
try{e.preventDefault()}catch(ex){}
try{if (e.preventDefault)
        e.preventDefault();
    else {
        e.cancelBubble = true;
        e.returnValue = false;
        e.keyCode = 0;
    }}  catch(ex){}
}

解决方案

I have seen the same issue. Some browsers will not allow you to capture certain shortcuts. Look at this https://stackoverflow.com/a/7296303/1366887

Some key combinations are resticted in Chrome 4, but not in Chrome 3. Look here: https://groups.google.com/a/chromium.org/forum/?fromgroups=#!topic/chromium-bugs/Ntc1byZXHfU

Here is the Javascript:

$(window).keydown(function(event) {
  if(event.ctrlKey && event.keyCode == 84) { 
    console.log("Hey! Ctrl+T event captured!");
    event.preventDefault(); 
  }
  if(event.ctrlKey && event.keyCode == 83) { 
    console.log("Hey! Ctrl+S event captured!");
    event.preventDefault(); 
  }
});

I have used this numerous times, and it has worked greatly.

Here is another rescource you can take a look at: http://unixpapa.com/js/key.html

Without Jquery:

onkeydown = function(e){
  if(e.ctrlKey && e.keyCode == 'S'.charCodeAt(0)){
    e.preventDefault();
    //your saving code
  }
}

Here is a JSFIDDLE of it working.
