How to find the parameter key from window location path?

I have query string is as follows.
Window.location.href = http://192.168.1.25:9990/myprofile?IkNBMTEyOTA4MjYyOSI.5sTmOAZU-ZNmqDpVIx4SnLjzsMs
I am trying window.location.search I am getting ?IkNBMTEyOTA4MjYyOSI.5sTmOAZU-ZNmqDpVIx4SnLjzsMs
But expected output : IkNBMTEyOTA4MjYyOSI.5sTmOAZU-ZNmqDpVIx4SnLjzsMs I need without ?

Try:
window.location.search.substring(1)

You can use searchParams.get() like this example :
var currentUrl = Window.location.href;
var url = new URL(currentUrl);
var c = url.searchParams.get("myprofile");
Check this link

var urlStr = "http://192.168.1.25:9990/myprofile?IkNBMTEyOTA4MjYyOSI.5sTmOAZU-ZNmqDpVIx4SnLjzsMs";
function getqueryString(url) {
var retObj = {};
if (!url) return retObj;
var str = url.split('?')[1];
if (!str) return retObj;
var query = str.split('&');
for (var i = 0; i < query.length; i++) {
var pair = query[i].split('=');
retObj[pair[0]] = pair[1];
}
return retObj;
}
var rsl = getqueryString(urlStr);
console.log(rsl)
You can use this function it takes URL as the parameter and returns Back all the query parameter in an object form

How to get specific parameter's value from the querystring in jquery/javascript?

I've following query string:
url = "http://56.177.59.250/static/ajax.php?core[ajax]=true&core[call]=prj_name.contactform&width=400&core[security_token]=c7854c13380a26ff009a5cd9e6699840"
I want to get the value of variable core[call] i.e. prj_name.contactform
How should I get this value using jQuery/javascript?
Please help me.

Try this, which puts all variables into the vars{} object. You can then access vars.core.ajax, vars.width, etc. Also live on this fiddle:
var u = "http://localhost:8080/static/ajax.php?core[ajax]=true&core[call]=prj_name.contactform&width=400&core[security_token]=c7854c13380a26ff009a5cd9e6699840&x=1"
var re = /(\w+)\[(\w+)\]$/
var vars = {}
u.split('?')[1].split('&').forEach(function(e) {
var p = e.split('=');
var v = p[0].match(re);
if (v === null) {
vars[p[0]] = p[1];
} else {
if (!(v[1] in vars)) { vars[v[1]] = {}; }
vars[v[1]][v[2]] = p[1];
}
});
console.log(vars);

Javascript location.search

How could I specifically get every of these query strings in
file:///K:/CKaing_C20_A01_Casino2/game.html?First+Name=Testfirst&Last+Name=Testlast&pnum=123-456-7890&postCode=A1A+1A1&startMoney=5000
For example, I want to get Testfirst, and then assign it to a variable so I can use it later on. Same thing with the others.
This is what I have so far to remove all the +, =
var formData = location.search;
formData = formData.substring(1, formData.length);
while (formData.indexOf("+") != -1) {
formData = formData.replace("+", " ");
}
formData = unescape(formData);
var formArray = formData.split("&");
for (var i=0; i < formArray.length; ++i) {
document.writeln(formArray[i] + "<br />");
}

var splitSearch = JSON.parse("{\""+(location.search.substr(1).replace(/\=/g,"\"\:\"").replace(/\&|(\/\?)/g,"\", \""))+"\"}")
I made that one for a webpage that uses a rare ("/?") separator too.
http://example.com/?a=0&b=bee/?c=third
First one will work for URLs like that
If you want it for a conventional location:
var splitSearch = JSON.parse("{\""+(location.search.substr(1).replace(/\=/g,"\"\:\"").replace(/\&/g,"\", \""))+"\"}")
Once splitSearch is defined you can get "pnum" string like this:
splitSearch.pnum
splitSearch["pnum"]
Another way to get it:
var splitSearch = JSON.parse("{\""+(location.search.substr(1).replace(/(\=)|(\&)|(\/\?)/g, function(k) {
var rtn=k;
if (k == "\=") rtn="\"\:\"";
else if ((k == "\&") /*|| (k == "\/\?")*/) rtn="\",\"";
return rtn;
})+"\"}"))

A mix of use of replace with regEx and the split function does the work.
var str = "file:///K:/CKaing_C20_A01_Casino2/game.html?
First+Name=Testfirst&Last+Name=Testlast
&pnum=123-456-7890&postCode=A1A+1A1&startMoney=5000";
var argStrIndex = str.indexOf("?");
var argStr = str.substring(argStrIndex+1);
var args = argStr.replace(/\+/g," ").split("&");
for (var i=0;i<args.length;i++){
alert(args[i]);
}
demo: http://jsfiddle.net/7meAv/

something like that :
var search = location.search
.replace(/^\?/,'')
.replace(/\+/g,' ')
.split('&')
.map(function(string){
var split = string.split('=');
var res={};
res[split[0]]=split[1];
return res;
});
should return
[{"First Name":"Testfirst"},{"Last Name":"Testlast"},{"pnum":"123-456-7890"},{"postCode":"A1A 1A1"},{"startMoney":"5000"}]"
You'd need to take care of url encoding though.

A combination of the two answers already given (jsfiddle: http://jsfiddle.net/russianator/GymEq/)
var url = 'file:///K:/CKaing_C20_A01_Casino2/game.html?First+Name=Testfirst&Last+Name=Testlast&pnum=123-456-7890&postCode=A1A+1A1&startMoney=5000';
queryObject = {};
url.substring(url.indexOf('?')+1)
.replace(/\+/g,' ')
.split('&')
.forEach(function(item) {
splitItem = item.split('=');
queryObject[splitItem[0]] = splitItem[1];
});
Returns an object like this:
{
"First Name": "Testfirst",
"Last Name": "Testlast",
...
}

How to get an url contained in query string

I want a javascript variable to be what is behind the ?url= in the url..
for example: The current url is
http://mywebsite.com/test/index.html?url=http://www.google.com/
So the variable has to be http://www.google.com/ .
I tried this, but it doesn't work… why ?
var url = document.URL ;
var appname = url.match(?url=(.+))[1];
Thanks.

I think the following will work for you:
function querystring(key) {
var query = window.location.search.substring(1);
var keys = query.split("&");
for (i = 0; i < keys.length; i++) {
var values = keys[i].split("=");
if (values[0] == key) {
return values[1];
}
}
}
var appname = querystring("url");
alert(appname);

Try this:
var regex = /\?url\=(.+)/;
var appname = regex.exec(url)[1];
or even simpler:
var appname = /\?url\=(.+)/.exec(url)[1];

var url = location.search.match(/url=([^&]+)&*.*$/)[1]; // http://www.google.com/
location //location object
.search //the search part in location
.match //return string according to regex given
[1] //second result (result in parenthesis)
//--------Use in a function---------
function getQuery(txt){
var result = location.search.match(new RegExp(txt + "=([^&]+)&*.*$"));
return result === null ? undefined : result[1];
}

javascript parser for a string which contains .ini data

If a string contains a .ini file data , How can I parse it in JavaScript ?
Is there any JavaScript parser which will help in this regard?
here , typically string contains the content after reading a configuration file. (reading cannot be done through javascript , but somehow I gather .ini info in a string.)

I wrote a javascript function inspirated by node-iniparser.js
function parseINIString(data){
var regex = {
section: /^\s*\[\s*([^\]]*)\s*\]\s*$/,
param: /^\s*([^=]+?)\s*=\s*(.*?)\s*$/,
comment: /^\s*;.*$/
};
var value = {};
var lines = data.split(/[\r\n]+/);
var section = null;
lines.forEach(function(line){
if(regex.comment.test(line)){
return;
}else if(regex.param.test(line)){
var match = line.match(regex.param);
if(section){
value[section][match[1]] = match[2];
}else{
value[match[1]] = match[2];
}
}else if(regex.section.test(line)){
var match = line.match(regex.section);
value[match[1]] = {};
section = match[1];
}else if(line.length == 0 && section){
section = null;
};
});
return value;
}
2017-05-10 updated: fix bug of keys contains spaces.
EDIT:
Sample of ini file read and parse

You could try the config-ini-parser, it's similar to python ConfigParser without I/O operations
It could be installed by npm or bower. Here is an example:
var ConfigIniParser = require("config-ini-parser").ConfigIniParser;
var delimiter = "\r\n"; //or "\n" for *nux
parser = new ConfigIniParser(delimiter); //If don't assign the parameter delimiter then the default value \n will be used
parser.parse(iniContent);
var value = parser.get("section", "option");
parser.stringify('\n'); //get all the ini file content as a string
For more detail you could check the project main page or from the npm package page

Here's a function who's able to parse ini data from a string to an object! (on client side)
function parseINIString(data){
var regex = {
section: /^\s*\[\s*([^\]]*)\s*\]\s*$/,
param: /^\s*([\w\.\-\_]+)\s*=\s*(.*?)\s*$/,
comment: /^\s*;.*$/
};
var value = {};
var lines = data.split(/\r\n|\r|\n/);
var section = null;
for(x=0;x<lines.length;x++)
{
if(regex.comment.test(lines[x])){
return;
}else if(regex.param.test(lines[x])){
var match = lines[x].match(regex.param);
if(section){
value[section][match[1]] = match[2];
}else{
value[match[1]] = match[2];
}
}else if(regex.section.test(lines[x])){
var match = lines[x].match(regex.section);
value[match[1]] = {};
section = match[1];
}else if(lines.length == 0 && section){//changed line to lines to fix bug.
section = null;
};
}
return value;
}

Based on the other responses i've modified it so you can have nested sections :)
function parseINI(data: string) {
let rgx = {
section: /^\s*\[\s*([^\]]*)\s*\]\s*$/,
param: /^\s*([^=]+?)\s*=\s*(.*?)\s*$/,
comment: /^\s*;.*$/
};
let result = {};
let lines = data.split(/[\r\n]+/);
let section = result;
lines.forEach(function (line) {
//comments
if (rgx.comment.test(line)) return;
//params
if (rgx.param.test(line)) {
let match = line.match(rgx.param);
section[match[1]] = match[2];
return;
}
//sections
if (rgx.section.test(line)) {
section = result
let match = line.match(rgx.section);
for (let subSection of match[1].split(".")) {
!section[subSection] && (section[subSection] = {});
section = section[subSection];
}
return;
}
});
return result;
}
