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:
function cnvtBack(encoded)
{
var orig = "";
for (i=0; i < encoded.length; i++)
{
var letter = "";
letter = encoded.charAt(i);
if (letter > 'a' && letter <= 'z')
letter = <<previous letter in alphabeta >> // HOW?
orig += letter;
}
}
I have this function that works well, but I ask ... is it possible to have a compact sintax to reduce the number of the char inside the text below ??
function change_txarea(val) {
if (val=='I') {
document.FrontPage_Form1.ob1.value = "Description " +[code3].....
Please help me to get all characters from every line from a word-wrapped div using javascript.Need to get all the characters for first line, second line, third line,... separately from the word-wrapped div.

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;

View 8 Replies View RelatedIs there a way to calculate the .offsetLeft or .left of a character in a string relative the element that contains the string? I'm just trying to wrap each character in an element and position the characters independently, so I have to set the .position to absolute, and set the .left and .top on each element as I create it so I can move the elements later on.

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

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.
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.

View 2 Replies View RelatedIn textareas or input textboxes, when you dynamically add '

find a char sequence in a string and highlight that with red color.
In text box when they start typing i will get list of string matching in a div. for example when they start typing "A", i will get a result as Atlantic Alaska Atlanta, some thing like this. high light "A" in all the String of the list to red color, in the same way when they type "AT", then "AT" in red color.

My assignment: Write a Java Script that will print out the Temperature in Celcius from 0 to 35, AND the corrosponding temperature in Fahrenheit. So basically it would generate the following:

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

Possible?
