Regex: Remove A Specified Parameter From URL
Jul 23, 2005
I need to write a function that will remove a specified parameter from a
URL. For example:
removeParam("param1", "http://mysite.com/mypage.htm?param1=1¶m2=2");
would return:
"http://mysite.com/mypage.htm?param2=2"
I'm thinking that string.replace(/regex/, ""); would do the trick, but how
do I construct a correct regex?
I see a problem if the parameter name ("param1") happens to contain any
characters that have a special meaning in a regular expression.

I need to remove non digits from a number.
I thought I could do this:
var phone=དྷ-p67s82'
var re=/D/g;
phone=phone.replace(re,'');
alert(phone) yields: 22-p67s82
What dumb thing am I missing. That regex removes nothing.

var k = $(".class").index(this);
i want to remove <li> element in the same way. I tried it with .get(k), but it didn't work.
<li>one</li>
<li>two</li>
<li>three</li>
So how to remove a second <li> tag with a parameter?

I am trying to use a regEx to grab Function names and function parameter names from a text entry.
The script is written in javascript and I expect the functions to be in javascript syntax.
For example the code might look like:
Code:
function myFunction1(param1,param2,param3){
some code
}
function myFunction2();
function myFunction3(param);
Whats the best way to accomplish grabbing the function names and parameters?
Should I be breaking it down into multiple regular expressions?

I'm currently reading jQuery - Novice to Ninja (fantastic book), and trying to understand how I can add several words to the code snippet below. I currently remove, let's say Sweden as below, but what if I also want to remove Norway?And another question, what if I would like to keep only Sweden and remove the rest from a list of twenty countries? How would I do that?
Code JavaScript:
jQuery(document).ready(function() {
jQuery('#countries tbody').remove(':contains("Sweden")');

I have a function which validates the password if there is a number:
-------------------------------------------------
function findNumeric(str_obj){
regEx = /d/;
if (str_obj.match(regEx))
return true;
else
return false;
}
--------------------------------------------------
The problem arises when I put a password with a space in between e.g:
'test test1'. The fucntion returns false. I've tried 's' in the
regEx but the user can put the space anywhere..
Any idea how to solve this problem as I should be able to put any
alplanumeric value into the password, including space.

I have a variable named "acct". I first want to remove any "-" characters
from it's value. After this I want to verify that we have only exactly 12
digits in the variable.
Unfortunately I'm pretty green as far as using RegEx.
/d{12}/.test(acct); should do the second part, but how do I do the first?

Basically i want to get the current url, and then replace http:// with
something else.
Here is the current code.
var current_url = window.document.location;
var re = new RegExp("http://", "g");
if(re.test(current_url)) {
me = current_url.replace(re,"http://www.addme.com/");
window.alert("found :: " + me + " :: " + current_url);
} else {
window.alert("not");}
if my page was http://ww.google.com 'd get the alert to be:
found :: undefined :: http://www.google.com.
I dont understand why i am getting undefined. When re.test() works.
surely that means the regex is correct.

Trying to match the entire following object literal code using a RegEx.
var Punctuators = { '{' : 'LeftCurly', '}' : 'RightCurly' }
Variations on the idea of using /var.*{.*}/ of course stops at the
first }.

I was using the following code:
element.value = element.value.replace(/ /g,'');
to remove all the spaces in a string.
However in IE6 it complained with and "Expected ')'" error.
How can I tell IE6 to replace just spaces (i.e. not using s)?
I tried / / and /[ ]/ but neither of them worked either.

/^(?=.*d)(?=.*[A-Z])(?=.*[a-z]).{8,16}$/

I'm writing an ECMAScript tokeniser and parser and trying to find out if I can eliminate the switching from tokenising "/" as start of regex or the division operator depending on the parser feedback - essentially, if I can make the tokeniser independent of the parser. (I have a gut feeling this needs too much special casing to be worth it). Code:

I have been playing with this regex for a few hours now I want to make it so it accepts commas also.
At the moment it works with A-z and - . ' but can't seem to figure out how to include commas.

i have the following regex:
(s*{s*(<?)s*(>?)s*}s*)
this needs to be able to match a string and make the following replacements:
if the string matches without < or >, replace the match with a space, a replacement string, and another space. if < matches also, do not add the left space. if > matches, do not add the right space. if < and > match, do not add the beginning or ending space
Old {} String => Old Replacement String
Old {<} String => OldReplacement String
Old {>} String => Old ReplacementString
Old {<>} String => OldReplacementString
this will have to be done a LOT of times, so efficiency is very important the answer in php is below. can anyone help me figure out how to do it in javascript? PHP Code:

In have a string of data like so:
<div id="feedback">
<p>[DEC 12th Anthony]I like it[DEC 12th Anthony]I agree</p>
</div>
I'm trying to use regex to add a <br /> before each item in hard brackets so the comments are broken out. Here's what I've tried.
re = /(.*])/gi;
vTemp = aSourceObject.innerHTML.replace(re,"<br />$1");
What I end up getting is:
<div id="feedback">
<p><br />[DEC 12th Anthony]I like it[DEC 12th Anthony]I agree</p>
</div>
It gets it right, but only for the first item, not the second one. If I tell it to put the <br /> after then I get
<p>[DEC 12th Anthony]I like it[DEC 12th Anthony]<br />I agree</p>
So its like its reading the entire section in brackets as one match instead of 2 seperate matches..

I don't know where the actual issue is, but hopefully someone can explain.
The following displays "5" in FireFox, but "3" in IE:
<script type="text/javascript" language="javascript">
var newString = ",a,b,c,";
var treeArray = newString.split(/,/i);
alert(treeArray.length);
</script>

I have a string I have to parse
AB1.2CD34
I need to split the string into groups of letters and numbers..
"AB" "1.2" "CD" "34"
What is the best way of doing this ?
I've looked at string.split using a regex, but that doesn't output the
delimiters.

I am trying to write a regex that will parse BBcode into HTML using
JavaScript. Everything was going smoothly using the string class
replace() operator with regex's until I got to the list tag.
Implementing the list tag itself was fairly easy. What was not was
trying to handle the list items. For some reason, in BBcode, they
didn't bother defining an end tag for a list item. I guess that they
designed it with bad old HTML 3.2 in mind where you could make a list
by using:
<ul>
<li>item 1
<li>item2
</ul>
However, I need to make this XHTML compliant, so I needed to add the
</li> tag into the mix. Unfortunately, the only way to find where to
put it is to find the next[*] (<li>) tag or an open list (in the case
of nested lists) or close list tag. I was trying to get a rule that
handles the list items to work, but it only matches the first item in
any list. Here is the line of code:
bbcode =
bbcode.replace(/[list(=1|=a|)](.*?)[*](.*?)([*]|[list]|[/list])/g,
'[list$1]$2<li>$3</li>$4');
First, I check to make sure that the list item is inside a list. Then,
I match the[*] tag to find the start of the item, then I match either
the next[*],, orto determine the end of the item.
This successfully prevents a list item outside of a list from being
made into a <li> element, but only matches the first list item in a
list. Is there any way to make this match all occurances of this
pattern without looping over the statement until the pattern can no
longer be found?
