var myString = "hello0x0there";
splitString = string.split(/(0x0){1}/);
in firefox the returned array is 3 elements long, with the middle one being the actual 0x0. is this the intended implementation, and why?
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!
is there any smart way to do split, and ignore certain delimiters, like:
var s = "don't use ',' as part of data, some other text";
arr = s.split(",");
// obviously don't want s to be splitted at ','
How do i split with multiple delimiters( i think )? im trying to split my split with multiple delimiters different values but i cant find a good way to do so.
does anyone know how to fix this? code...
I'm trying to write a RegExp that will return search an array and
return the closest 10 matches, for example, if i entered "Hel" and my
array contained "Hello", "Hell", it would return Hello and Hell,
however, if i entered "ell" it wouldn't return anything.
The code that i need to modify is: -
var searchterm = "Hel";
var re = new RegExp("^")
re = /^/
if(searchterm !='')
{
var matches = 0;
for(var i=0; i<myarray.length; i++)
{
if(searchme != false)
{
if (searchterm == myarray[i])
{
write (myarray[i]);
matches++;
}
}
if(matches==10) break
}
}
Obviously this is only returning exact matches and having tried to add
the RegExp into there hasn't worked as yet.
i have a function (below) which reads the last n lines from a text
file. rather than read the whole line and output it as is, i want to be
able to read the line and split the tab delimited text file so I can
present it in columns, exclude unwanted data etc....
I have code...
how can I convert these to an array so I can loop through the values?

For some reason, when i split a basic string in IE I'm getting an extra value in the array which is something like this:
function(v,n){n = (n==null)?0:n; var m = this.length;for(var i = n;
That's the actual value. Here's the call I use:
var value = "test@test.com, test1@test1.com";

How can I split a piece of text like the following : /mysite/subSection into an array like the following :
array(

[1] => subSection

I am very new to javascript and programming and I need a little direction. I have working a javascript that reads the value of radio buttons and writes them to a text file. My code is at [URL]. The text file has the following format:
Name|Email|Location|Comment|5|5|5|3|2|1|4|5|3|2|0
Name2|Email2|Location2|Comment2|1|3|0|3|2|0|2|5|1|2|3
What I need to do is have javascript read the text file (c: estfile.txt) and put each section of information (name, comments, numbers, etc.) into an array. Then, add the number from each columns up. For example, the first number from Name and the first number from Name1 is 5 +1 = 6. This sum is then added to another array that can be printed on the screen. I know this is a lot of information.
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.+:.+
}{};
How can I split a string like this:
IE, Firefox, Opera, Chrome, Safari
I want the string to be splitted after each ,
Then I want that each splitted part is placed in a variable, preferable in an array, so I can loop through the array with an foreach or something.
I have a homework assignment which is pretty simple. It is a grade calculator that uses arrays to gather the grades from the user. This is what I have for the problematic section:
var homework = new Array(2);/* The grades entered by the user for Homework 1, 2, and 3 */
var project = new Array (3);/* The grades entered by the user for Project 1, 2, 3, and 4 */
[Code].....
My problem is the document.write portion of the code, where it is supposed to return either homework[0], project [0], or exam[0], it instead returns undefined. There is no problem with any other subscript. And yes, it does successfully prompt me for each of the [0] subscripts in the first part of the code. Am I just missing something that is right in front of my face? Does all arrays not start with the [0] subscript?

targetValue = targetValue[i];
// Search until found or end of array

arrayToSearchIn[searchIndex]!=targetValue) {
i++searchIndex++;

return String.fromCharCode(CHAR_CODE_A + searchIndex);
} else {
return -1;

This is my code and I have figured it to create an array from the prompt and then use the function to return the first array it finds but I cant seem to make it go on to the next index of the array. I know that when you return a value the function closes and I have tried to store my return in a variable but its not working the way I want it to or I'm not writing the correct command or is there away to do multiply returns, I think what I need to do is simply but I have been staring at this screen for a while now and just cant see it.
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.

This seems like a really stupid question. Can you include a javascript
file in a javascript file?
Rather than doing this:
<script src="A"></script>
<script src="B"></script>
I want to do
<script src="A"></script>
and then have in script A:
include("B");
where include is a magic word that includes the file B.
How do you include javascript in the definition of a jsp TLD. for example if i have a TLD called <mytld: body everytime I include this in a page, I also want some javascript to be included.
Is this done in the Java definition of the tld element?
I have a website where I need to fill its contents after retrieving
some data from another system (not a DB, but you can think like it).
I know the nature of the data, but the order that it is retrieved is
random, and there is no way to order it. Therefore, it is giving me
some pain to produce the html code.
I was thinking of having the following javascript to place my html
code. Here, "rightImg" is the ID of a DIV tag where I want to position
my code. The code should be the content of the htmlBody variable.
function addTopRightImage() {
var htmlBody = '.'
if (document.all) {
document.all('rightImg').innerHTML = htmlBody;
}
else if (document.getElementById) {
document.getElementById('rightImg').innerHTML = htmlBody;
}}
However, if I set the variable as it is shown bellow, the page is not
loaded as I want:
var htmlBody = '<jsp:include page="/WEB-INF/Standard.jsp"
flush="true"><jsp:param name="id" value="${myid}" /></jsp:include>'
Does anyone have a clue of what is going wrong? Maybe an alternative
solution?
i downloaded a script and im trying to understand the code, while trying to edit it as i want it. The script inside the php file is included in the body section.when i try to take this code into a separate file and adding it into the head section, the whole thing ONLY works on firefox :S none other browser which is very odd.

I'm looking for a way to include javascript files from within a ".js"
file. This would allow me to only need to link to one ".js" file, and
yet still organize my functions into non gargantuan files for easy
editing. I'm hoping there is some sort of include or import directive
that I could use. Or if no such directive exists, I'm wondering if
anyone has written one which I could use.
I need to do this without any server side scripting. For now at least,
the html is being used locally with local files. Code:
I have to create a web page to give to clients that is shipped on CD.
The idea is that they would open the page and it would display in their
web browser.
What this will do is to provide a list of most recent changes to the
software we're shipping. The idea is that there would be an un-ordered
list <ul/> with a list of changes (not sure of final desired mark-up).
What we want to do is to get the developers to edit a file that simply
contains a list of changes, putting in minimal markup. This "changes"
file would then be "included" in some way into a parent file that
contains all the branding and other information. We don't want the
developers to have to navigate their way around this parent file
looking for where to edit it.
As this page will be launched in a browser from disk, there won't be
any help provided by a web server, so I'm really stumped as to how to
accomplish this....could it be done with JavaScript at all?
I'm extremely new to JavaScript programming, so bear with me pleace.
