Match Regex Globally Then Loop Through Result?

Mar 27, 2011

I've got the current script which returns 1 match in matches[0] with a url, but I need it to return ALL occurrences in the string.And then I need to know how to loop through the matches and display each "url" in this case.Nothing I've tried seems to find more than 1 match even when [string] contains a list of urls, which indicates I've done something wrong.

Return Match Using Regex

May 18, 2007

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

<div id="wrapper">
<a href="#">a great link that contain text and symbols</a>
<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

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>...).

JQuery :: Use Regex To Match A Value In Form Input?

Jul 16, 2010

I'm trying to create a branching form wherein the user selects a date using the datepicker plugin, then, depending on whether they choose a weekday or a Saturday, they are presented with one or the other of 2 select lists to choose the time.

I'm just getting started, and I can't seem to get the regex right. Here's a simplifed version of the relevant part of the datepicker,

$(function() {
$(".datepicker").datepicker({dateFormat: 'D, mm-dd-yy',buttonText: 'Click Me!', });

and here's the initial test to see if the chosen date falls on a weekday or a Saturday:

$(document).ready(function() {
$(':input[name=datepicker]').change(function() {
if ($(this).val()!=/^Sat,.*/)

RegEx - Match Non-alphanumeric Characters But Ignore?

Jul 18, 2009

We have been using the following js/regex to find and replace all non-alphanumeric characters apart from - and + outputString = outputString.replace(/[^w|^+|^-]*/g, "");

However it doesn't work entirely - it doesn't replace the ^ and | characters. I can't help but wonder if this is something to do with the ^ and | being used as meta-characters in the regex itself.

I've tried switching to use [W|^+|^-], but that replaces the - and +. I thought that possibly a lookahead assertion may be the answer, but I'm not very sure how to implement them.

Apr 28, 2011

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.

Make A Script Globally Available To Entire Domain With ONE Download?

May 5, 2011

By my understanding, if I want to use a given JS on multiple pages, I need to call for that script in each page.

If I understand correctly, it then downloads it, and the functionality is then available to that given page.

Now, presuming that I've got that at least mostly correct, it seems like there should be a way to just download it once, and use it till the session is over. My thinking is to call for the heavy JS's on the welcome page after a succeful login, and then not have to slow down each and every page by calling for those same scripts.

Is this common, or at least possible?

Are there specific reasons to not do this?

JQuery :: (tablesorter) Globally Sort Multiple Tables On A Page?

May 13, 2009

I am using the excellent jquery.tablesorter successfully for a large number of 40-row tables that live together on one page. So far I'm very happy with the plugin. My users also need the ability to apply any column sort they invoke automatically to *all* tables on the pae. They do not wish to sort the tables individually. As recommended in another thread, I have been looking at sortStart and sortEnd, but have been pulling my hair out trying to get this working. My JS:

<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
// extend the default setting to always sort on the first column
$.tablesorter.defaults.sortList = [[0,0]];

Recursive Function With For Loop, For Loop Is Breaking When Calling Itself

Jan 22, 2011

I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together.

What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array.

What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created.

Here is the test object:

test = [
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [


'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking.

Send A Loop Variable (i) To A Function Inside The Loop

Aug 4, 2011

I'm looking to send a loop variable (i) to a function inside the loop, but I can't seem to get it to use the value I want, it keeps making it a reference of i and therefore the function is always called using the last value of i rather than the one it was set with.

So if i have 5 Tabs then Tab 1, when clicked, should call DefaultTabClick(0) and so on rather than always using 4 for any of the tabs.

RegEx In Javascript

Jul 23, 2005

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;
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.

RegEx In Javascript?

Jul 23, 2005

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?

Issues Getting And Regex'ing A Url

Jan 9, 2006

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,"");

window.alert("found :: " + me + " :: " + current_url);
} else {

if my page was 'd get the alert to be:

found :: undefined ::

I dont understand why i am getting undefined. When re.test() works.
surely that means the regex is correct.

Space In REGEX In IE6

May 9, 2007

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.
