我找到了解決問題的辦法。它使用普通的舊Javascript完成，並應與大多數瀏覽器兼容。如果沒有，請隨時舉報。
/**
* addKeyActions takes an array of objects that looks like this:
*
* {
* keyCodes: [120], //F9
* modifiers: ['ctrlKey', 'shiftKey', 'altKey', 'altGraphKey', 'metaKey'], //Only legal modifiers
* callback: function(event){};
* }
*
* A good resource to find the keycodes you are looking for is:
* http://www.cambiaresearch.com/articles/15/javascript-char-codes-key-codes
*
* However, there are more keycodes than written on this page, so if you can't find what you are looking for,
* I have provided a function that you can call to display the keycode for the current button pressed - alertKeyCodes

請注意，函數和使用位置的定義在2個獨立的文件中。一個是從準備好文檔開始的調用以及上面的定義。
$(document).ready(function() {
var SingleKeys = {

callback: function(event){return preventDefaultEventPropagation();}
};

keyCodes: [8], //Backspace
callback: function(event){
var sourceOfEvent = event.target || event.srcElement;
if(sourceOfEvent.tagName == "BODY"){
return preventDefaultEventPropagation();
}
}
};
var EnterKeys = {
keyCodes: [13], //Enter
callback: function(event){
var sourceOfEvent = event.target || event.srcElement;
if(sourceOfEvent.tagName == "BODY"){
return preventDefaultEventPropagation();
}
if(sourceOfEvent.tagName == "INPUT" && sourceOfEvent.type == "text"){
return preventDefaultEventPropagation();
}
}
};
var AltKeys = {
keyCodes: [36, 37, 39], //Home, Left, Right
modifiers: ['altKey'],

};
var CtrlKeys = {

什麼是您的jQuery版本？ –
它們全都未能被阻止，或者它是特定的鍵。 –
這可能是一種替代方法：http://stackoverflow.com/questions/1400528/is-there-a-way-to-capture-override-ctrl-r-or-f--on-ie-using-javascript此外，你應該在事件處理程序中返回false。 –
