I need to know what page i'm on based on the URL.
When i use $(location).attr('href')i get a very long url like this:
http://localhost:8181/research/gadgets/ifr?container=default&mid=0&nocache=0&country=ALL&lang=ALL&view=default&nerwVersion=~project.version~&url=http%3A%2F%2Flocalhost%3A8181%2Fresearch%2Fnerw-gadgets%2FCompanyDetails%2FCompanyDetails.xml&oaaParent=http%3A%2F%2Flocalhost%3A8181
The URL in the browser looks like this:
http://localhost:8181/research/?view=home
How do i get the view=home bit?

Try This:-
function getQuerystring(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(window.location.search);
return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
Usage getQuerystring("view");

Get URL parameters & values with jQuery

How to pass the values from one page to other page using the url in jquery.
I got few examples from google, below is my code but not able to pass the values.
Can any one help me on this ?

This is the function I always use in my work
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
from an SO answer here. Please note that you don't need to use jquery for this.
To use it:
Given a URL
http://www.example.com?testParam=value
get its value by
var myVal = getparameterByName("testParam");
I hope it helps.

How do I make a more specific url for location.href.match?

I am using a series of if statements to manipulate css on a forum using the following:
if(location.href.match(/(showforum=3)/i) != null) {
$(document).ready(function(){
$("#topimg").addClass("announce");
});}
The code works perfectly fine, but every other showforum beginning with a 3 displays this image unless I code it otherwise. So my question would be how do I make my location more exact so that it only makes changes to 3 and not 3x? Is it even possible using this coding?

Change your regex so that the "value's boundary" is checked as well:
var pattern = /showforum=3(?=&|$)/i;
if (pattern.test(location.href)) {
...
}
Note the accompanying change in the testing expression: if you only need to find out whether or not some string matches the pattern, you should use regexp.test(string) syntax, not string.match(regexp) !== null.

function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
if( getParameterByName("showforum") == 3 ){
//........
}

How do I get query string value [duplicate]

I need to grab only the value 60408571 from the following url:
http://www.domain.com/ProductDetail.aspx?ProductId=60408571&this-is-a-page-title-that-goes-here
So far, I've successfully been able to grab everything after ?ProductId=, but this returns:
60408571&this-is-a-page-title-that-goes-here
The JavaScript I'm currently using is:
if(window.location.href.indexOf("ProductId") > -1) {
s.prop14 = window.location.search.replace("?ProductId=", "");
}
I only want to grab the numerical value if the page the user is on is a page with ProductId in the url.
Thank you for your help.

Thanks Tom. I modified my code, based on the reference Tom provided, and I now have:
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
if(window.location.href.indexOf("ProductId") > -1) {
//s.prop14 = window.location.search.replace("?ProductId=", "");
s.prop14 = getParameterByName('ProductId');
}
Works great! Thanks again.

If the URL won't change you can also do this way:
var productId = findProductId(window.location.query);
function findProductId(url){
return url.split('&')[0].split('=')[1];
}

How replace query string values using jQuery?

I have a problem , my original URL looks like this:
test.com/?manufacturer=0&body-style=0&min-price=270%2C000&max-price=780%2C000
As you can see, the min-price and max-price values in the query string is not correct due to the comma that is passed to the URL. It should be in their respective integer value like min-price=270000 and max-price=780000.
I need to convert the query string values of min-max and max-price using jQuery. I currently do not how to do this actually. But I have codes to get them from the URL and then convert them to the correct value. I just don't know how to implement them back to the URL (as new URL) using jQuery. These are my existing codes:
//Function to get value of parameter in query string
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
//Function to remove commas and convert to number
function convert_to_pure_number(x) {
//Remove commas
var x_withoutcommas=x.replace(/,/g,'');
//Convert to plain number
var y =parseInt( x_withoutcommas ,10);
return y;
}
var min_price_original=getParameterByName('min-price');
var max_price_original=getParameterByName('max-price');
var min_price_converted=convert_to_pure_number(min_price_original);
var max_price_converted=convert_to_pure_number(max_price_original);
Any suggestions how will I continue the above code with the additional code to put them back to the URL posted? Thanks for any help.
UPDATE
This is the process:
Form will be posted to the server--> URL will contain commas --> My new code will remove the comma --> In the query string value, correct value will be used.
Cheers.

use replace function like this :
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
var min_price_original=getParameterByName('min-price').replace('%2C','');
var max_price_original=getParameterByName('max-price').replace('%2C','');
