Using Jquery to get numeric value which is in between "/" in link

I am trying to fetch numeric value from link like this.
Example link
/produkt/114664/bergans-of-norway-airojohka-jakke-herre
So I need to fetch 114664.
I have used following jquery code
jQuery(document).ready(function($) {
var outputv = $('.-thumbnail a').map(function() {
return this.href.replace(/[^\d]/g, '');
}).get();
console.log( outputv );
});
https://jsfiddle.net/a2qL5oyp/1/
The issue I am facing is that in some cases I have urls like this
/produkt/114664/bergans-of-norway-3airojohka-3jakke-herre
Here I have "3" inside text string, so in my code I am actually getting the output as "11466433" But I only need 114664
So is there any possibility i can get numeric values only after /produkt/ ?

If you know that the path structure of your link will always be like in your question, it's safe to do this:
var path = '/produkt/114664/bergans-of-norway-airojohka-jakke-herre';
var id = path.split('/')[2];
This splits the string up by '/' into an array, where you can easily reference your desired value from there.

If you want the numerical part after /produkt/ (without limitiation where that might be...) use a regular expression, match against the string:
var str = '/produkt/114664/bergans-of-norway-3airojohka-3jakke-herre';
alert(str.match(/\/produkt\/(\d+)/)[1])
(Note: In the real code you need to make sure .match() returned a valid array before accessing [1])

how to replace part of part of string in javascript

I have two GUIDs. I am looking for to replace c013d94e from 1st guid with cd11d94e of second guid in Javascipt.
I checked javascript replace() method but not sure how i can use it with my specific case.
c013d94e-3210-e511-82ec-303a64efb676 - 1st Guid
cd11d94e-3210-e511-82ec-303a64efb676 - 2nd Guid
Following is my code where i am trying to do it
for(var i=0; i < response[1].length;i++)
angular.forEach($scope.studentPermissions[i][0].Children, function (subject) {
string 1stGuid= response[1].data[i].Id; // it contains cd11d94e-3210-e511-82ec-303a64efb676
subject.Id = // it contains c013d94e-3210-e511-82ec-303a64efb676
});

replace takes 2 parameters, the first is the string to search for and the second is the replacement string. It doesn't modify the original string, it simply returns a new string with the value replaced.
You can perform your replace like this:
var guid = 'c013d94e-3210-e511-82ec-303a64efb676';
guid = guid.replace('c013d94e', 'cd11d94e');
console.log(guid); // 'cd11d94e-3210-e511-82ec-303a64efb676'

#Jamen. Yes the other part of 1st string will always be same. How can i use concatenate?
You don't even need to use replace then? Just make a brand new string:
var guid = "cd11d94e-3210-e511-82ec-303a64efb676";
But, to actually answer the question in the title:
var input = "c013d94e-3210-e511-82ec-303a64efb676";
var output = input.replace("c013d94e", "cd11d94e");
console.log(output); // cd11d94e-3210-e511-82ec-303a64efb676
But like I said, in your situation this shouldn't be necessary, based on the quote.

javascript regex match not working as expected

I'm trying to do something very simple, but I can't get to work the way I intend. I'm sure it's doing exactly what I'm asking it to do, but I'm failing to understand the syntax.
Part 1:
In the following example, I want to extract the part of the string between geotech and Input.
x = "geotechCITYInput"
x.match(/^geotech(.*)(?:Input|List)$/)
The result:
["geotechCITYInput", "CITY"]
I've been writing regex for many years in perl/python and even javascript, but I've never seen the ?: syntax, which, I think, is what I'm supposed to use here.
Part 2:
The higher level problem I'm trying to solve is more complicated. I have a form with many elements defined as either geotechXXXXInput or geotechXXXXList. I want to create an array of XXXX values, but only if the name ends with Input.
Example form definition:
obj0.name = "geotechCITYInput"
obj1.name = "geotechCITYList"
obj2.name = "geotechSTATEInput"
obj3.name = "geotechSTATEList"
I ultimately want an array like this:
["CITY","STATE"]
I can iterate over the form objects easily with an API call, but I can't figure out how to write the regex to match the ones I want. This is what I have right now, but it doesn't work.
geotechForm.forEachItem(function(name) {
if(name.match(/Input$/)
inputFieldNames.push( name.match(/^geotech(.*)Input$/) );
});
Any suggestions would be greatly appreciated.

You were missing the Input and List suffix in your regex. This will match if the name starts with geotech and ends with either Input or List and it will return an array with the text in the middle as the second item in the array.
geotechForm.forEachItem(function (name) {
var match = name.match(/^geotech(.*)(Input|List)$/);
if (match) {
inputFieldNames.push(match[1]);
}
});

JS Regex match string with $

I am trying to write something that would look at tweets and pull up info about stocks being mentioned in the tweet. People use $ to reference stock symbols on twitter but I cant escape the $.
I also dont want to match any price mention or anything like that so basically match $AAPL and not $1500
I was thinking it would be something like this
\b\$[a-zA-Z].*\b
if there are multiple matches id like to loop through them somehow so something like
while ((tweet = reg.exec(sym_pat)) !== null) {
//replace text with stock data.
}
This expression gives me an unexpected illegal token error
var symbol_pat = new RegExp(\b\$[a-z]*);
Thanks for the help if you want to see the next issue I ran into
Javascript AJAX scope inside of $.each Scope

Okay, you've stated that you want to replace the matches with their actual stock values. So, you need to get all of the matching elements (stock ticker names) and then for each match you're going to replace the it with the stock value.
The answer will "read" very similarly to that sentence.
Assume there's a tweet variable that is the contents of a particular tweet you're going to work on:
tweet.match(/\b\$[A-Za-z]+\b/g).forEach(function(match) {
// match looks like '$AAPL'
var tickerValue = lookUpTickerValue(match);
tweet.replace(match, tickerValue);
});
This is assuming you have some logic somewhere that will grab the ticker value for the given stock name and then replace it (it should probably return the original value if it can't find a match, so you don't mangle lovely tweets like "Barbara Streisand is $ATAN").

var symbol_pat = new RegExp('\\b\\$[a-z]+\\b','gi');
// or
var symbol_pat = /\b\$[a-z]+\b/gi;
Also, for some reason JS can not calculate the beginning of a word by \b, it just catches the one at the end.
EDIT: If you're replacing the stock symbols you can use the basic replace method by a function and replace that data with predefined values:
var symbol_pat = /(^|\s)(\$[a-z]+\b)/gi;
var stocks = {AAPL:1,ETC:2}
var str = '$aapl ssd $a a$s$etc $etc';
console.log(str);
str = str.replace(symbol_pat, function() {
var stk = arguments[2].substr(1).toUpperCase();
// assuming you want to replace $etc as well as $ETC by using
// the .toUpperCase() method
if (!stocks[stk]) return arguments[0];
return arguments[0].replace(arguments[2],stocks[stk]);
});
console.log(str);

Change href value using jQuery

How do I rewrite an href value, using jQuery?
I have links with a default city
parks
malls
If the user enters a value into a #city textbox I want to replace Paris with the user-entered value.
So far I have
var newCity = $("#city").val();

Given you have unique href values (?what=parks, and ?what=malls) I would suggest not writing a path into the $.attr() method; you would have to have one call to $.attr() for each unique href, and that would grow to be very redundant, very quickly - not to mention difficult to manage.
Below I'm making one call to $.attr() and using a function to replace only the &city= portion with the new city. The good thing about this method is that these 5 lines of code can update hundreds of links without destroying the rest of the href values on each link.
$("#city").change(function(o){
$("a.malls").attr('href', function(i,a){
return a.replace( /(city=)[a-z]+/ig, '$1'+o.target.value );
});
});
One thing you may want to watch out for would be spaces, and casing. You could convert everything to lower case using the .toLowerCase() JavaScript method, and you can replace the spaces with another call to .replace() as I've down below:
'$1'+o.target.value.replace(/\s+/, '');
Online Demo: http://jsbin.com/ohejez/

$('a').attr("href", "/search/?what=parks&city=" + newCity);

As soon as a key is released within the #city input field, the href will be updated.
$('#city').keyup(function(){
$('a').attr('href','/search/?what=parks&city='+$(this).val());
});

Like this:
var newCity = $("#city").val();
$('a').attr('href', '/search/?what=parks&city=' + newCity);
EDIT: Added the search string
