下面就是實現(xiàn)效果所需代碼:
function click(e) { if (document.all) { if (event.button==1||event.button==2||event.button==3) { oncontextmenu='return false'; } } if (document.layers) { if (e.which == 3) { oncontextmenu='return false'; } } } if (document.layers) { document.captureEvents(Event.MOUSEDOWN); } document.onmousedown=click; document.oncontextmenu = new Function("return false;") var travel=true var hotkey=17 /* hotkey即為熱鍵的鍵值,是ASII碼,這里99代表c鍵 */ if (document.layers) document.captureEvents(Event.KEYDOWN) function gogo(e) { if (document.layers) { if (e.which==hotkey&&travel){ alert("操作錯誤.或許是您按錯了按鍵!"); } } else if (document.all){ if (event.keyCode==hotkey&&travel){ alert("操作錯誤.或許是您按錯了按鍵!"); }} } document.onkeydown=gogo 把上面的代碼另存為一個JS文件,然后在想實現(xiàn)此效果的頁面調(diào)用即可! |
