is it possible to combine the the following functions with each other in an array for example and if so, would someone be kind enough to show me how. the reasons are 1. to see if it is at all possible and 2. to learn so that I can combine further possibilities in the future. the first script compares user keywords from search mashines and the second replaces certain strings/paterns with others.

I have a validation regular expression: [?&-#$%():;,._ 0-9a-zA-Z] in a hundreds of pages in edit boxes. Is there anyway I can on-the-fly add two items to this list: (after a page loads)
1) A single quote : '
2) A double quote : "
Sort of like a search and replace for the ENTIRE form (html document).
I want to replace a string after checking it is valid by passing the values to a function.
The string is '<img width="300" height="300">'
Code:
var text = '<img width=300 height=300>'
text = text.replace(/<img width=(.*?) height=(.*?)>/gi, check_img($1, $2));
The $1 and $2 values are not being passed to the function.
This same method works in PHP by the e Modifier but not in JS.

If I find a line like this: Code: |Note|Dur:16th,Grace|Pos:n-10^|Opts:Stem=Up , I will have to insert the first character after Pos: (n, b, or #) into the Pos: field of a later "Chord" line (will be a list separated by commas). If there is a number (positive or negative) following Pos:, nothing needs to be done.

this will match any instance of a number following a letter/[a-z][0-9]/gmiso thatvar str="abc123 456";alert(str.replace(/[a-z][0-9]/gmi,''));would return "ab23 456".
how would i replace just the number? so as to get back "abc23 456" - or ideally "abc 456" ?
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.
View 14 Replies View RelatedWhat's the best way to search all visible text on a page and do a find eplace on a string?
I've seen all sorts of ways to do it by tag type or ID... but I want to scan the entire page.
My page populates a table with a list of names and other information from a
JavaScript object. I receive changes (adds, change & delete) to that list,
convert it into a JavaScript object. I do understand how to add the new
names to the list.
I have 3 questions:
1) How can I search through the table rows to find the rows to be changed
or removed?
2) How can I resort the table, so the names continue to appear in
alphabetical order.
3) How can change or remove data in the cells, once I've found the
appropriate row?
i have a implementation where i need to perform a search and replace. i will try to explain to the best of my ability. i have a variable, var a = "THIS IS SOME SOME TEXT";
then i have another array variable, var b = new Array(); which contains elements in key=value format eg. SOME=NEWSOME so what i need to do is, i need to loop through this array and if SOME exists in var a, then i need to replace it with NEWSOME. so for each value before =, if it exists in var a replace it with whats after =. and replace only once, so if SOME exists multiple times just replace the first occurence.
so essentially my final string would be, THIS IS NEWSOME SOME TEXT.
I want to change this code so that I can have multiple word variables I can change, possibly separated by comas I guess?.. Open to other idea's as well. Do you also know how I can make it so that it's NOT case sensitive? Code:

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 need to search and replace patterns in web pages, but I
can't find a way even after reading the ad hoc chapter in New Rider's
"Inside JavaScript".
Here's what I want to do:
function filter() {
var items = new Array("John", "Jane");
for (x = 0; x < items.length; x++) {
//Doesn't work
pattern = '/' + items[x] + '/'
//Doesn't work either
document.body = document.body.replace(pattern,"IGNORED");
}
ie., create an array of items to look for in the BODY section of the
page, and if any item exists, replace the item with IGNORED.
Anyone knows how to do this?

View 2 Replies View RelatedI have a large string, but need to search for a specific character and replace it only if it is between two other items.

View 8 Replies View RelatedIn a string (that contain the Flash version installed), I want to replace:
all "," by "."
"win" by <nothing>
all spaces by <nothing>
So far I do it this way:
strFlashVer = strFlashVer.replace(/,/g, '.');
strFlashVer = strFlashVer.replace('win', '');
strFlashVer = strFlashVer.replace(/ /g, '');
but I'm sure theres better way (I'm not really good with reg exp).
I'm trying to reduce a large number of pdf files to text format. Acrobat has a batch processing feature that will convert the files, and also allows a JavaScript to be executed as part of the conversion process.
I would like to add JavaScript code that allows me to replace and/or remove certain text/characters from the file.
Examples would be:
A) Remove all double, triple, multi-spaces and carriage returns
B) Change all uppercase characters to lowercase
C) Remove all punctuation
What i'm really aiming for is to be able to run the batch process in Adobe, then have a javascript filter out all that junk within a file with X amount of lines, not just one.
I have around 100,000 html files that I need to do a search/replace on. I currently have the word "Manchester" in all of these files which needs replacing with the full file path location;

I coudn't understand some behavior of RegExp.test function.
Example html code:
----------------
<html><head></head><body><script type="text/javascript">
var r = /^https?:///g;
document.write( [
r.test('http://a'),
r.test('http://b'),
r.test('http://c'),
r.test('http://d')
]);
</script></body></html>
---------------------
The page displays true, false, true, false. (in Opera, Firefox and IE)
This is strange because I expected it would display true, true, true,
true. There must be something I didn't know about the function
RegExp.test.
What is the best way to execute a function when the user clicks and holds an element for, say, 3 seconds? A Google search didn't reveal anything, but I couldn't really come up with a concise search query either. The only way I can think of is setting a timeout onclick, and clearing it onmouseup. Is this the best method?
On a somewhat related note, I am trying to check if the user has entered a valid time, in the form (m)m:ss, where the first m is optional. I decided to use a regular expression. (Is that the best way?) So far I have come up with [0-5][0-9]:[0-5][0-9], however, this allows other characters at the beginning or end of the string, as well as forcing the first character. If I change the first character to [0-5]?, it makes the first character optional but it allows times that don't meet that requirement - which basically defeats the purpose of having that rule at all.
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.
The javascript below is looking for the word 'margaret thatcher' in the body and surrounding it with a link. It's lower-case but the script is ignoring the case so that won't matter. But, the problem is that because Margaret Thatcher is a proper noun, it will be capitalized in the body text yet replaced with lower-case text. How can I modify this script to look for the word while ignoring the case but use the same text it found as the replacement instead of using the text object?
