I have a string that is encoded simply by replacing the letter with the
next letter in the alphabeta. I need a function to convert it back.
Following is the function:

How To Get Width Of A Space Char

Feb 15, 2009

I wrote the following function to get a font metrics table and it works for all printable characters except spaces. Does anyone know how I could get the width of a space char with known font, size etc...?

I tried several different variations on the "node.style.whiteSpace" line and also tried using an html entity   (which gave me the width of the string ' ') but nothing seems to work. All I'm getting for spaces is zero width.

javascript Code:

function JSFontMetrics(inFont, inSize, inWeight, inVariant, inStyle)
{
var node= document.createElement('span');
var text= document.createTextNode('');
var width = 0;

[Code].....

Type More Than 1 Char Into A Drop Down List

Jan 10, 2005

I cannot remember the site nor the author, but it works BEAUTIFULLY!
I have changed the timeoutInterval to 500 milliseconds as I type with one finger - the original was 250 or even less.

<script language="JavaScript">
// script allows you to type more than one character into a drop-down list
//
//A typical drop-down need to have ONKEYPRESS and ONKEY functions added
//
//Example: <SELECT ID='vc_DESCRIPTION' NAME='vc_DESCRIPTION' onkeypress='listbox_onkeypress()' onblur='listbox_onblur()'>


var toFind = ""; // keyboard buffer
var timeoutID = ""; // process id for timer - when stopping the timeout
var timeoutInterval = 500; // milliseconds - keyboard buffer
var timeoutCtr = 0; // initialise of timer countdown
var timeoutCtrLimit = 3; // number of times timer is allowed to count down
var oControl = ""; // maintains a global reference to the user control

function listbox_onkeypress(){

window.clearInterval(timeoutID)
oControl = window.event.srcElement;
var keycode = window.event.keyCode;

if(keycode >= 32 ){
var c = String.fromCharCode(keycode);
c = c.toUpperCase();
toFind += c ;
find(); // search the listbox
timeoutID = window.setInterval("idle()", timeoutInterval); // restart the timer
}
}

function listbox_onblur(){ // function is called when user leaves listbox

window.clearInterval(timeoutID);
resetToFind();
}

function idle(){ // function is called if timeout expires - 3rd time stops timer and clear kb buffer

timeoutCtr += 1

if(timeoutCtr > timeoutCtrLimit){
resetToFind();
timeoutCtr = 0;
window.clearInterval(timeoutID);
}
}

function resetToFind(){

toFind = ""
}

function find(){

var allOptions = document.all.item(oControl.id);

for (i=0; i < allOptions.length; i++){
nextOptionText = allOptions(i).text.toUpperCase();

if(!isNaN(nextOptionText) && !isNaN(toFind) ){
nextOptionText *= 1;
toFind *= 1;
}

if(toFind == nextOptionText){
oControl.selectedIndex = i;
window.event.returnValue = false;
break;
}

if(i < allOptions.length-1){
lookAheadOptionText = allOptions(i+1).text.toUpperCase();

if( (toFind > nextOptionText) && (toFind < lookAheadOptionText) ){
oControl.selectedIndex = i+1;
window.event.cancelBubble = true;
window.event.returnValue = false;
break;
}
}
else{

if(toFind > nextOptionText){
oControl.selectedIndex = allOptions.length-1
window.event.cancelBubble = true;
window.event.returnValue = false;
break;

}

Limit Char Over Two Textarea Boxes?

Sep 8, 2005

I have a form where users can enter text in one or two textareas. If they only enter text in of of the textareas I can limit the max char to 300 using this:

<script type="text/javascript">
var maxL=300;//nr of max permited characters
function limit(obj){
var nr= document.getElementById('nrc')
var v = new String();
s = obj.value.split('');
for(i=0;i<maxL;i++){v += s[i]}
if(s.length>=maxL){
obj.value=v;
nr.firstChild.data = maxL-v.length;
}
else{nr.firstChild.data = maxL-s.length;}
}
onload=function(){
document.getElementById('nrc').firstChild.data=maxL;
}
</script>

Is there a way that I can limit the total char between the two textareas i.e. If a user enters 180 in the first one they can only enter 120 in the second one.

Identifying Invalid Char Position Using RegExp

Jul 23, 2005

I would like to use one or more RegExps to validate country names as having
the first and last words beginning with an uppercase letter, intermediate
words beginning with either uppercase or lowercase, and all other characters
being lowercase characters. For example:

Turks and Caicos

The difficult part is that I want to obtain save the string positions of the
invalid characters in an array, rather than just obtain a true or false
value.

Can anybody with more experience with Regular Expressions than me suggest
some code, sites, or approaches.

Regexp - Negative Match For Fixed String (vs. A Char List)?

Mar 28, 2007

Is there a way in a regexp to *not* match a fixed string value?

Using [^blah] gives matches to anything not containing *any* of letters
b,l,a and h. Whereas I want to match anything that does not containing
the exact string 'blah', i.e. *all* the letters.

Possible?
