使用event對象的keyCode屬性判斷輸入的索引值
eg:if(event.keyCode==13)alert(“enter!”);
索引值對應表

如果要使用按鍵組合,則可以利用event.ctrlKey,event.shiftKey,event .altKey判斷是否按下了ctrl鍵、shift鍵以及alt鍵
===============================================
JS的event對象Event屬性和辦法:
1. type:事務的類型,如onlick中的click;
2. srcElement/target:事務源,就是產務的元素;
3. button:聲明被按下的滑鼠鍵,整數,1代表左鍵,2代表右鍵,4代表中鍵,若是按下多個鍵,酒把這些值加起來,所以3就代表閣下鍵同步選取; (firefox中 0代表左鍵,1代表中心鍵,2代表右鍵)
4. clientX/clientY:事務產生的時辰,滑鼠相對於瀏覽器視窗可視文檔地區的左上方的地位;(在DOM標準中,這兩個屬性值都不推敲文檔的遷移轉變 景象,也就是說,無論文檔遷移轉變到哪裡,只要事務產生在視窗左上方,clientX和clientY都是 0,所以在IE中,要想獲得事務產生的座標相對於文檔開首的地位,要加上
document.body.scrollLeft和 document.body.scrollTop)
5. offsetX,offsetY/layerX,layerY:事務產生的時辰,滑鼠相對於源元素左上方的地位;
6. x,y/pageX,pageY:檢索相對於父要素滑鼠程度座標的整數;
7. altKey,ctrlKey,shiftKey等:返回一個布爾值;
8. keyCode:返回keydown何keyup事務產生的時辰按鍵的代碼,以及keypress 事務的Unicode字元;(firefox2不支撐 event.keycode,可以用 event.which調換 )
9. Element,toElement:前者是指代mou搜刮引擎最佳化ver事務中滑鼠移動過的文件項目,後者指代mou搜刮引擎最佳化ut事務中滑鼠移動到的文 檔元素;
10. cancelBubble:一個布爾屬性,把它設定為true的時辰,將停止事務進一步起泡到包涵層次的元素;(e.cancelBubble = true; 相當於 e.stopPropagation();)
11. returnValue:一個布爾屬性,設定為false的時辰可以組織瀏覽器履行預設的事務動作;(e.returnValue = false; 相當於 e.preventDefault();)
12. attachEvent(),detachEvent()/addEventListener(),removeEventListener:為制訂 DOM對象事務類型註冊多個交易處理懲罰函數的辦法,它們有兩個參數,第一個是事務類型,第二個是交易處理懲罰函數。在
attachEvent()事務履行的時辰,this關鍵字指向的是window對象,而不是產務的那個元素;
13. screenX、screenY:滑鼠指標相對於顯示器左上方的地位,若是你想開啟新的視窗,這兩個屬性很首要;
一些申明:
1. event代表事務的狀況,例如觸發event對象的元素、滑鼠的地位及狀況、按下的鍵等等;
2. event對象只在事務產生的過程中才有效。
firefox裡的event跟IE裡的不合,IE裡的是全域變數,隨時可用;firefox裡的要用參數勾引才幹用,是運行時的姑且變數。
在IE/Opera中是window.event,在Firefox中是event;而事務的對象,在IE中是 window.event.srcElement,在Firefox中是event.target,Opera中兩者都可用。
3. 下面兩句結果雷同
var evt = (evt) ? evt : ((window.event) ? window.event : null);
var evt = evt || window.event; // firefox下window.event為null, IE下event為null
4. IE中事務的起泡
IE中事務可以沿著包涵層次一點點起泡到上層,也就是說,基層的DOM節點定義的交易處理懲罰函數,到了上層的節點若是還有和基層雷同事務類型的事務 處理懲罰函數,那麼上層的交易處理懲罰函數也會履行。例如, div 標籤包含了 a ,若是這兩個標籤都有onclick事務的處理懲罰函數,那麼履行的景象就是先履列標籤 a 的onclick交易處理懲罰函數,再履行 div 的交易處理懲罰函數。若是的交易處理懲罰函數履行完畢之後,不履行上層的 div 的onclick的交易處理懲罰函數了,那麼就把cancelBubble設定為true即可
