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 am trying to figure out how to set up my reg exp search so that the search
will only match on the exact word.
Here is the current problem code:
Word1 = "RealPlayer.exe"
Word2 = "Player.exe"
RegExp re = Word2;
if (re.Find(Word1))
{
bFound = TRUE;
}
Currently the bFound is set to TRUE since "Player.exe" is found within
"RealPlayer.exe". But I only want bFound to be TRUE is if the entire word
matches.
I need a regexp function which makes a match when the string contains <img...AND the img tag above dows NOT contain a certain path Here is what I have:
<imgs.*(src).+>
This matches if my string contains "<img .....src.....>" (the dots can be anything, I dont care). However, after the "src" part and before the ....
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.
Can someone please let me know what this matches - i can work out some but not all code...

View 4 Replies View RelatedI have this string: this is my test <a href="yay.html">yay</a> and want to just match the part before the <a...: this is my test I can't figure out the regular expression for this. I've tried everything I can think of. It seems that it needs to do a non-greedy search on the first < it finds, but nothing works, like: ((.*<)?)

how would i replace just the number? so as to get back "abc23 456" - or ideally "abc 456" ?
why I get an array containing [xml, xml]
Code:
str = 'index.xml'
re = RegExp( /([^s./]+)$/ ) ;
str.match(re) // -> [xml, xml]
I only need xml, not an array, and especially not [xml, xml]
Update: thnx mrhoo, thats clear now!
how can I do a multiple replaces without using regexp? Right now I just have a while that keeps checking if it exist, then if it does, replacing it. Not very efficient.

How to check if some char in textbox contains one of the ones in string "allowedChars"
Is 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

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.
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].....
How can I check if a number exists by itself in this string by using
the RegExp object?
var mystring = "11,111,01,011";
var match = "1";
var re = new RegExp( match );
var isFound = re.test( mystring ) );
Running this code returns 'true' which is not what I want since number
one doesn't exist by itself. I need to use the "match" variable since
it will change depending on user input.
I can only get it to work without variables in the expression. E.g.
var re = new RegExp( /1/ );
I just want the list to move along with the screen whilst scrolling. I tried a css version and that didnt work. I found this one but my blogger html checker says this when I try to save/preview:

I'm trying to create a script where all the hyperlinks in a page will be replaced with a new set of coding before it. (e.g: a href="this.htm?http://www.google.com").
My code generates this change through a series of random numbers and only runs the script when "2" is the generated number (out of 12). Now, I only know how to replace all occurrences of "href" in all "a" tags, but there are times when I use Javascript to launch new windows or even javascript to navigate to the top of a page.
I tried to use a string match method to search for occurrences of "javascript:" and so forth, but I can't seem to get it working. Code:

I am trying to do a pattern match and check something in a condition but cant get it to work. The first value changes and I need to check and do something if I get a hit on it.

if (mydata.indexOf("first") == "something")

Basically I am trying to find out if first is equal to one in the mydata string. My above attempt is not working.
I have a zip code field in my form.
I have a list of allowable zip codes:
43001,43002,43003, etc...
How do I validate against them so the user can only enter one of the zip codes in the list? I assume I have to put the list in to an array.
