Disable Right Click using Javascript
Simple way yo disable right click:
<body oncontextmenu="return false;">
Using script:
<script>
var isNS = (navigator.appName == "Netscape") ? 1 : 0;
if(navigator.appName == "Netscape") document.captureEvents(Event.MOUSEDOWN||Event.MOUSEUP);
function mischandler(){
return false;
}
function mousehandler(e){
var myevent = (isNS) ? e : event;
var eventbutton = (isNS) ? myevent.which : myevent.button;
if((eventbutton==2)||(eventbutton==3)) return false;
}
document.oncontextmenu = mischandler;
document.onmousedown = mousehandler;
document.onmouseup = mousehandler;
</script>
From: http://www.reconn.us/content/view/36/45/
Now...
Can i disable right click only on images?
Yes, by using getElementsByTagName i can set no right click on images only
<script>
function noRtClk(){
return false;
}
//document.oncontextmenu = noRtClk;
var e=document.getElementsByTagName("img");
for(var i=0;i<e.length;i++)
{
e[i].oncontextmenu = noRtClk;
}
</script>

meta refresh problem in IE7
<meta equiv="Refresh" content="3;url=http://mysite.com">
this meta tag will redirect to the specified url in 3 seconds.
but it won't work in Internet Explorer 7.
BUT...
we can use a script...
function Refresher(t) {
if(t) refresh = setTimeout("document.location='http://www.mysite.com';",
t*1000);
}
Then call it inside body tag..
<BODY onLoad="Refresher(20)">Cheers!

php explode and implode
Use of Explode and implode functions
Explode - splits a string by a string
eg:
$a = explode("/","23/02/2008");
then
$a[0] = "23"
$a[1] = "02"
$a[2] = "2008"
Implode - joins array elements into string with a string
$b = implode("-",$a);
then
$b = "23-02-2008"

Getting Last generated auto increment value in mysql
Some tables have auto increment field.
after executing a insert command in mysql, sometimes we may want to know the last added value.... for that we can use
mysql_insert_id()
function
eg:
mysql_query($sql3); //executing some query
$last_num = mysql_insert_id(); //last added value
Cheers!

how to change the alert box title?
Want to know how to change the alert box title in javascript...
the answer is: we cant change the title of js alert box.
however, we can use popup boxes, that look like alert boxes with custom title.... but there is a chance - some browsers will block that.
Or we can use vbscript msgBox, but cant get the result in FF.
Or we can use custom designs like this:
http://www.acejs.com/scriptsfolder/121015/121015.html
BUT it is not working like exactly as a alert box. (following codes will get executed though we dont click the ok button)
My opinion: Its better not to use any other custom alert boxes.
