TỔNG HỢP CÁC CODE JAVASCRIPT HAY

1. Cấm click chuột phải:


Code:
<SCRIPT language=JavaScript1.1> function right(e) { if (navigator.appName == 'Netscape' && (e.which == 3 || e.which == 2)) return false; else if (navigator.appName == 'Microsoft Internet Explorer' && (event.button == 2 || event.button == 3)) { alert('Chuc Mot Ngay Vui ve - Gui Wedsite Cho Ban Be Cua Minh Nha !'); return false; } return true; } document.onmousedown=right; if (document.layers) window.captureEvents(Event.MOUSEDOWN); window.onmousedown=right; </SCRIPT> 

2. Không cho phủ khối văn bản để copy:

<script type="text/javascript"> 

/*********************************************** ********** Disable Text Selection script *************** ***********************************************/ function disableSelection(target){ if (typeof target.onselectstart!="undefined") //IE route target.onselectstart=function(){return false} else if (typeof target.style.MozUserSelect!="undefined") //Firefox route target.style.MozUserSelect="none" else //All other route (ie: Opera) target.onmousedown=function(){return false} target.style.cursor = "default" } //Sample usages //disableSelection(document.body) //Disable text selection on entire body //disableSelection(document.getElementById("mydiv")) //Disable text selection on element with id="mydiv" </script> 

3. Code chống click chuột phải và nếu người dùng cố tình click nữa thì web sẽ tự động giựt màn hình cảnh báo:

<SCRIPT language=JavaScript> document.onmousedown=click var times=0 var times2=10 function click() { if ((event.button==2) || (event.button==3)) { if (times>=1) { earthquake() } alert("Ban Ko Dc Click Chuot Phai"); times++ } } function earthquake() { alert("Ban Ko Dc Click Chuot Phai"); window.moveTo(0, 0) window.moveTo(1, 1) window.moveTo(2, 2) window.moveTo(3, 3) window.moveTo(4, 4) window.moveTo(5, 5) window.moveTo(6, 6) window.moveTo(7, 7) window.moveTo(8, 8) window.moveTo(9, 9) window.moveTo(10, 10) window.moveTo(9, 9) window.moveTo(8, 8) window.moveTo(7, 7) window.moveTo(6, 6) window.moveTo(5, 5) window.moveTo(4, 4) window.moveTo(3, 3) window.moveTo(2, 2) window.moveTo(1, 1) alert("Giat Nhu Fiml Nha??!") tremmors() } function tremmors() { window.moveTo(0, 0) window.moveTo(1, 1) window.moveTo(2, 2) window.moveTo(3, 3) window.moveTo(4, 4) window.moveTo(5, 5) window.moveTo(6, 6) window.moveTo(7, 7) window.moveTo(8, 8) window.moveTo(9, 9) window.moveTo(10, 10) window.moveTo(11, 11) window.moveTo(12, 12) window.moveTo(9, 9) window.moveTo(8, 8) window.moveTo(7, 7) window.moveTo(6, 6) window.moveTo(5, 5) window.moveTo(4, 4) window.moveTo(3, 3) window.moveTo(2, 2) window.moveTo(1, 1) tremmors() } </SCRIPT> 

4. Vòng tròn lấp lánh bao quanh chuột:
