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.

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?

I have a simple form with an options drop down box:
<form method="POST" name="form">
<select autocomplete="off" id="input" name="input" onchange="this.form.submit();goHere();">
<option>Choose...</option>
[code]....
I wish to identify the option chosen in the function but not by its value, by its position:
<script>
function goHere(){
var s = document.getElementById("input");
[code]....
I was hoping that variable "u" would be either 0, 1, 2, or 3.How can I get a variable to alert me the position of the selected option in the form? I think it is elements[i].

I need to come up with a function
function regExpPos (text, re, parenNum) { ... }
that will return the position within text of RegExp.$parenNum if there
is a match, and -1 otherwise.
For example:
var re = /some(thing|or other)?.*(n(est)(?:ed)?.*(parens) )/
var text = "There were some nesting parens in the test";
alert (regExpPos (text, re, 3));
should show 17
Would anyone have one of these?

I'm finally diving into regexp by porting a perl script over to js that uses regexp to compress javascript into a bookmarklet capable format.I've successfully worked out 90% of the expressions but am troubled with a few, this one at the moment is odd:I want to remove the first line if it hasjavascript:So I thought str.replace(/^javascripts+:s+/, "") would be ok. I want javascript text, any space, colon, any space and new line. what I'm doing wrong.btw this is the original perl version
$src =~ s{^// ?javascript.+:.+
}{};

I found this in felgall's page. I added script tag
<script type="text/javascript">
var re = /(t)he/g;
var mystring = "Over the moon.";
re.text(mystring);
alert(RegExp.input); // or RegExp.$_
alert(RegExp.leftContext); // or RegExp["$`"]
alert(RegExp.rightContext); // or RegExp["$'"]
alert(RegExp.lastMatch); // or RegExp["$&"]
alert(RegExp.lastParen); // or RegExp["$+"]
alert(re.source);
</script>
I don't see message box. Please tell me what I can do.

I have a list of checkboxes with Ids that go something like;
chk_AGE=16
chk_AGE=17
chk_AGE=18
[code].....
When a user checks/unchecks '16' (for example), I want javascript to look up how many checkboxes in my form have an Id that begins with "chk_AGE" and return the number in an alert box ("3" in this case).If my user had checked/unchecked "Officer" an alert box would return "2" as there are 2 checkboxes that begin "chk_RANK".

I have a function, triggered when a particular type of link is clicked,which collects and inserts some text after the parent of the clicked link. This function works fine when the parent is a p tag, but I'm having trouble when the link is within a list tag. In this instance I would want the new text to be presented after the closing list item tag. How do can I distinguish whether the clicked link is within a p tag or within an li tag?
<tt>function fnGetSnippet(ni){
$.get("../scripts/ajax_fsheets.asp?id=getDD&ddID=" + ni +
"&q=" + new Date().getTime(), function(responseText){
<x-tab></x-tab>

Anyone know if there's a simple way of revealing all elements on a page that have a title attribute? I want to stick a script in a favelet to use as a development tool (highlight all titled elements with red border, etc)
I don't want it to be limited just to links or form elements.
If there's not something already out there, I'll probably have a hack at some existing favelets I have on my site, but no harm in asking if one's out there already, eh?

When we refresh the page (F5, or icon in browser), it will first
trigger ONUNLOAD event and then trigger
ONLOAD event. When we close the browser (X on right top icon), it will
trigger ONUNLOAD event.
Now when ONUNLOAD event is triggered, there is no way to distinguish
between
refresh the page or close the browser.
Here's the code fragment. The logic in window_unload() only applies to
closing the browser, not refreshing the page.
<BODY ONUNLOAD="window_unload()">
function window_unload()
{//logic that only applies to close the browser, not refresh the page.
}
Anyone knows the workaround to the problem?

I am developing a fairly complicated application with a lot of JavaScript and making use of JQuery. The application repeatedly makes simultaneous GET requests.
I am looking for a way of assigning a unique token to each request when it is made, so that I can store information about that request and cache the request / response combo, when using $.get() (or potentially $.ajax() if required for the extra functionality).
So far I have not had any joy and after a while googling this am none the wiser. I have used similar functionality in Flex 3 with the AsyncToken object which can maintain data between HTTP request / response.

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 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;
