Function To Match & Substitute
Jan 10, 2006
I can remember seeing a function some time ago, but I cannot recall
what it was or how to use it.
I am wanting to have two arrays - oldArray & newArray.
I need a function which I can call so that it will look inside the
specified string ("theString") and replace each instance of each entry
of oldArray with the corresponding entry in new Array.
Example:
theString = "12345678";
oldArray = new Array("1","2","3");
newArray = new Array("One","Two","Three");
theString = theString.XXX(oldArray,newArray);
// theString = "OneTwoThree45678";
Any ideas, suggestions, references?

I have one (1) XML file that is used to display job announcement data in two ways:
1. an RSS feed
2. an HTML file using javascript.
The RSS feed displays everything and that is good. But for the HTML file I only want some of the data to display not all of it. For instance, I want to display the announcements from the xml file ONLY where <grade> (<grade>FS-0203-7</grade>) starts with the letters "FS". I have tried this IF STATEMENT: if (("grade").match(/FS.*/)); but it does not work. How do I use Match so that it only writes grades from the XML file that start with "FS" or is there a better way to do this?

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 have been working on this for a few hours and am frustrated
beyond all extent. I have tried to research this on the web as well
with no success. I am trying to match certain contents within a
wrapper div. So for example if the inside of the wrapper div was the
following:
<div id="wrapper">
<a href="#">a great link that contain text and symbols</a>
<div... </div>
<div... </div>
</div>
I would like to strip out all the internal div's. But because there
can be alot of internal div's, I figured it would be less processor
intensive to just match the first 'a' tag and repopulate the wrapper
div with the match. I am trying to use something like the following
regex:
re = /^<a(.+)</a>/;
with the following statment:
$temp = document.getElementById('wrapper').innerHTML.match (re);
but this is returning the entire contents of the wrapper div. I have
tried variations of the regex and either continue to get the entire
contents or null returns. Any help would greatly be appreciated.
BTW, I can't match to the first because the contents may be touching (ie ...</a><div>...).

How do I extract "somestring" only? I'm on IE7.
<script type="text/javascript">
var x = "(EVAL)(H:somestring)Some other Text here";
var full =(x.match(/(H:(.*?))/g)); // produces "(H:somestring)" as expected
alert(full);
var inside = (x.match(/(H:(.*))/)); // produces "(H:somestring),somestring" .. I only
want "somestring"
alert(inside);
</script>

How would i use a wildcard in String.match()? For example, I would like to see if a variable contains www.*.com, where the * can be replaced with anything. How could i go about doing that?

I 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: ((.*<)?)

I'm working on an AJAX calendar. Visitors can select a date, fill out a form to request a meeting, and click submit. Here's what's crazy. My calendar has two parts: the top part displays the meetings for each day as well as the form and the bottom part displays the actual calendar. When you click submit, the top part update correctly, but using the same variable, the bottom part is incorrect. After doing some debugging I found that the variable for some reason changes between the php and javascript.
The rest of the code is unimportant because it does not pertain to my question. I have a callback function (show_cal) that uses eval() to parse the javascript built on the server. The getEvents function works without a hitch. The getCalendatMonth does not and here's why: in the php, the echo "alert(\"" . $date . "\");"; shows the correct response (2009-28-09) however the alert(date); in my Javascript only returns a random year (1975, 1976, 2000). Does anyone have any suggestions about why the two alerts would be different?
Here's the code.
java script:
function getCalendarMonth(date)
{
if(http.readyState ==4)
{

I'm trying to match all integers before and after the hyphen:
12345-5
This is what I tried but always returns null
Code:
var divID = '12345-5';
var idPattern = /^[0-9]+$/; //Matching one or more numbers before the hyphen
var id2Pattern = /^-[0-9]+$/; //Matching starts from the hyphen and all numbers that proceed

I have a regular expression called mCheck and a variable called usrVal which contains Ƈ/20/41/11/22' I then use the usrVal.match(mCheck) so the code looks like the following
var mCheck = /^[0-9][0-9]/;
if(!usrVal.match(mCheck))
{
usrVal = Ɔ' + usrVal;
}
Now, I was under the impression that if there wasn't a match then the match method would return boolean 'False'. However it is returning 'null' instead... I have used this exact same check on other pages before and it returned false just fine....

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.

Normally I can write regular expressions decently well but for some
reason I am having trouble getting this to work. I am validating form
data and need to throw an error if there are ANY spaces in the field.
abc123 is fine, abc 123 is not. Any character is fine, just not a
space.

Bit of a noob question, but I'm using the following code to get a menu tab to highlight/switch classautomatically based on the id of the page in the querystring. All is working well until the page ids hit double digits. Subsequently a menu with the link "p=10" and above will highlight when "p=1" in the location bar. How should Iamend the code to prevent this partial match? The menu item links always end after "p="; there are no furtherkeys in the querystring toact as a delimiter.

I am trying to get good using the $.each() in jQuery. I have a simple little task that I want to solve.
I have created a simple page with 100 boxes, each box with 4 colors. What I want to happen is if you click one box, it will change colors to the next box and so on. so for example here are 4 boxes
Red | Green | Blue | Yellow
If you click on Red you would get:
Green | Green | Blue | Yellow
If you click on the Green (1st one) you would get:
Blue | Green | Blue | Yellow
I have created a jsfiddle for you to view with what I have so far. I am stumpped at creating a match for the class name and if it matches to then go onto the next color in the array.
