i have an array and i want to insert "ZZ" if the current array value(string) contains "ata", the code should replace at the end of "ata" word.
var duplicatesArray = ["abıca","abrık","apşak","abbak","abu","aparma","apalisına","appak","aparmadutı","apşak","apışık","apşak","apışıklık","apışık","apalak","apılamak","apul","apul","apulamak","aparmak","at","arkasına","gelmek","ata","atabeg","at","eri","at","ağaç","at","oğlanı","at","akdarıcı","at","otayıcı","at","uşağı","at","oğlanı","at","oynağı","at","bırakmak","at","boynuna","düşmek","at","boynuna","düşmek","at","cıvlandurmak","at","çapmak","at","çapmak","at","depretmek","at","depmek","atı","doldurmak","at","segirtmek","ateş","evi","ateş","göyniigi","atışmak","ateşe","urmak","ateşe","nal","komak","at","şalmak","at","şalmak","at","tonı","at","kaşnısı","at","kaldırmak","at","kulağı","at","koparmals","at","koşmak","at","kulağı","götliği","atlaz","atlandurmak","atlandurmak","atlanmak","atlu","azuğı","atımı","yir","ata","atalar","atıcıduğı","aç","itmek","acıtğan","acıtmak","aç","dirilmek","acır","acırak","acışıklık","acışmak","aç","tutmak"
];
var uniqueArray = duplicatesArray.filter(function(elem, pos) {
return duplicatesArray.indexOf(elem) == pos;
});
for (var i = 0; i < uniqueArray.length; i++) {
var st = uniqueArray[i];
if((st.endsWith("mak")==false) && (st.endsWith("mek")== false) && (st.length>3))
{
var b = "ata";
var insert = "ZZ";
var position = st.indexOf("b");
st = st.slice(0, position) + insert + st.slice(position);
document.writeln(st);
document.write("<br>");
}
}
I may need to edit this answer later once some details have been clarified, but it seems like you should use the .map() method on your uniqueArray.
This code will walk through each word in the list and either let it unchanged or apply the replacement if all conditions are fulfilled.
// using a shorter, already deduplicated list for sake of clarity
var uniqueArray = [
"abıca","gelmek","ata","atabeg","at","eri","yir","atalar","tutmak"
];
var result = uniqueArray.map(function(word) {
return (
!word.endsWith("mak") &&
!word.endsWith("mek") &&
word.length > 3 ?
word.replace(/ata/, "ataZZ") : word
);
});
console.log(result);
I am right or wrong? :)
var initialArray = ["abıca","abrık","apşak","abbak","abu","aparma","apalisına","appak","aparmadutı","apşak","apışık","apşak","apışıklık","apışık","apalak","apılamak","apul","apul","apulamak","aparmak","at","arkasına","gelmek","ata","atabeg","at","eri","at","ağaç","at","oğlanı","at","akdarıcı","at","otayıcı","at","uşağı","at","oğlanı","at","oynağı","at","bırakmak","at","boynuna","düşmek","at","boynuna","düşmek","at","cıvlandurmak","at","çapmak","at","çapmak","at","depretmek","at","depmek","atı","doldurmak","at","segirtmek","ateş","evi","ateş","göyniigi","atışmak","ateşe","urmak","ateşe","nal","komak","at","şalmak","at","şalmak","at","tonı","at","kaşnısı","at","kaldırmak","at","kulağı","at","koparmals","at","koşmak","at","kulağı","götliği","atlaz","atlandurmak","atlandurmak","atlanmak","atlu","azuğı","atımı","yir","ata","atalar","atıcıduğı","aç","itmek","acıtğan","acıtmak","aç","dirilmek","acır","acırak","acışıklık","acışmak","aç","tutmak"];
var newArray = []
var regexp = /(ata)(.*)?/;
for (var i = 0; i< initialArray.length; i += 1) {
newArray.push(initialArray[i].replace(regexp, "$1ZZ$2"))
}
console.log(newArray)
// ... "gelmek", "ataZZ", "ataZZbeg" ...

I want to get the name from current url and assign it to a text box.
http://www.myabc.com/123/kdkd?refid=hari-doss
I just want to display "hari-doss" from the above url in a text box.
Note that the name is dynamic one. It will change depends on the user account.
Could anyone please help me out.
var url = "http://www.example.com/username_here801";
var urlsplit = url.split("/");
var username = urlsplit[3];
$('#textboxid').val(username);
the following script will give you the name.there is a function for extract query string at url
var QueryString = function () {
// This function is anonymous, is executed immediately and
// the return value is assigned to QueryString!
var query_string = {};
var query = window.location.search.substring(1);
var vars = query.split("&");
for (var i = 0; i < vars.length; i++) {
var pair = vars[i].split("=");
// If first entry with this name
if (typeof query_string[pair[0]] === "undefined") {
query_string[pair[0]] = pair[1];
// If second entry with this name
} else if (typeof query_string[pair[0]] === "string") {
var arr = [query_string[pair[0]], pair[1]];
query_string[pair[0]] = arr;
// If third or later entry with this name
} else {
query_string[pair[0]].push(pair[1]);
}
}
return query_string;
}();
var name = QueryString.refid;
This is a function that I have been using for the past couple of years -
function getQueryStringValue(key) {
key = key.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + key + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
Here is the usage -
$('#textbox').html(getQueryStringValue(refid));
This allows you to return the value of any key in a query string and also allows for changes to the query string (more values, etc.)
Do this:
//for getting current page URL
//var current_url = document.URL;
//so considering the current page URL = http://www.myabc.com/123/kdkd?refid=hari-doss
var current_url = "http://www.myabc.com/123/kdkd?refid=hari-doss";
var pos = current_url.lastIndexOf("=");
var name = current_url.substring(pos+1, current_url.length);
alert(name);//with output "hari-doss"

i have problem regarding how to compare string in an array..
in my list have jack,john,nami#domain,nami
function **alreadyInList**(list, toBeAdded) {
// return true or false
var delims = "(,)";
var tokens = list.split(delims);
for ( var i = 0; i < tokens.length; i++){
if (tokens[i] === toBeAdded ){
return true;
}
else
return false;
}
}
function addListTo(selectbox, textbox) {
var values = new Array();
var c = 0;
for ( i = 0; i < selectbox.options.length; i++) {
if (selectbox.options[i].selected) {
if (!**alreadyInList**(textbox.value,selectbox.options[i].value)) {
values[c++] = selectbox.options[i].value;
}
}
}
if (values.length == 0) return;
var v = values[0];
for (i = 1; i < values.length; i++) {
v += ',' + values[i];
}
if (textbox.value.length>0) {
if (textbox.value=='Any') {
textbox.value = v;
} else {
textbox.value += ',';
textbox.value += v;
}
} else {
textbox.value += v;
}
}
when i put my condition and i want to add the string into textbox it only work for the first string lets say i put nami as my string then when i want to put nami again it cannot so it works..but after "," i put name#domain .i can put back nami..means i dont want to repetitive string inside my textbox.can someone help me.sorry im still new in this programming..sorry for my english
Here is a revised version of your function to check if a name appears twice in any string in the array
function alreadyInList(list, toBeAdded) {
// return true or false
var delims = ",",
tokens = list.split(delims),
found = false;
var end = tokens.forEach(function (value) {
if (value.indexOf(toBeAdded) !== -1 && found == false) {
found = true;
alert('It\'s been found!');
// Do something
return true;
}
return false;
});
if (found != true) {
alert('Not in the list');
return false;
} else {
return false;
}
}
alreadyInList('marry,joe,gerry', 'marry');
JSFiddle Demo
Additionally if its just one occurance in the list you need something simple without a function.
var str = "marry,joe,gerry",
key = "marry";
if ( str.indexOf(key) !== -1 ) {
// Its found! Do something
}
As Sasquatch pointed out above, the issue is the delimiter you are using for split. You want to split by a single comma ',' -- not by the three characters '(,)'.
The way your code is written, tokens only ever has a single value because the split delimiter is wrong. It is matching the entire string variable list to your toBeAdded string and returning false.
My problem is I am trying to extract certain things from the url. I am currently using
window.location.href.substr()
to grab something like "/localhost:123/list/chart=2/view=1"
What i have now, is using the index positioning to grab the chart and view value.
var chart = window.location.href.substr(-8);
var view = window.location.href.substr(-1);
But the problem comes in with I have 10 or more charts. The positioning is messed up. Is there a way where you can ask the code to get the string between "chart=" and the closest "/"?
var str = "/localhost:123/list/chart=2/view=1";
var data = str.match(/\/chart=([0-9]+)\/view=([0-9]+)/);
var chart = data[1];
var view = data[2];
Of course you may want to add in some validation checks before using the outcome of the match.
Inspired by Paul S. I have written a function version of my answer:
function getPathVal(name)
{
var path = window.location.pathname;
var regx = new RegExp('(?:/|&|\\?)'+name+'='+'([^/&,]+)');
var data = path.match(regx);
return data[1] || null;
}
getPathVal('chart');//2
Function should work for fetching params from standard get parameter syntax in a URI, or the syntax in your example URI
Here's a way using String.prototype.indexOf
function getPathVar(key) {
var str = window.location.pathname,
i = str.indexOf('/' + key + '=') + key.length + 2,
j = str.indexOf('/', i);
if (i === key.length + 1) return '';
return str.slice(i, j);
}
// assuming current path as described in question
getPathVar('chart');
You could split your string up, with "/" as delimiter and then loop through the resulting array to find the desired parameters. That way you can easily extract all parameters automatically:
var x = "/localhost:123/list/chart=2/view=1";
var res = {};
var spl = x.split("/");
for (var i = 0; i < spl.length; i++) {
var part = spl[i];
var index = part.indexOf("=");
if (index > 0) {
res[part.substring(0, index)] = part.substring(index + 1);
}
}
console.log(res);
// res = { chart: 2, view: 1}

How can I get query string values in JavaScript?

Duplicate This question has been answered, is not unique, and doesn’t differentiate itself from another question.
I need to parse the query string www.mysite.com/default.aspx?dest=aboutus.aspx.
How do I get the dest variable in JavaScript?
Here is a fast and easy way of parsing query strings in JavaScript:
function getQueryVariable(variable) {
var query = window.location.search.substring(1);
var vars = query.split('&');
for (var i = 0; i < vars.length; i++) {
var pair = vars[i].split('=');
if (decodeURIComponent(pair[0]) == variable) {
return decodeURIComponent(pair[1]);
}
}
console.log('Query variable %s not found', variable);
}
Now make a request to page.html?x=Hello:
console.log(getQueryVariable('x'));
function parseQuery(queryString) {
var query = {};
var pairs = (queryString[0] === '?' ? queryString.substr(1) : queryString).split('&');
for (var i = 0; i < pairs.length; i++) {
var pair = pairs[i].split('=');
query[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1] || '');
}
return query;
}
Turns query string like hello=1&another=2 into object {hello: 1, another: 2}. From there, it's easy to extract the variable you need.
That said, it does not deal with array cases such as "hello=1&hello=2&hello=3". To work with this, you must check whether a property of the object you make exists before adding to it, and turn the value of it into an array, pushing any additional bits.
You can also use the excellent URI.js library by Rodney Rehm. Here's how:-
var qs = URI('www.mysite.com/default.aspx?dest=aboutus.aspx').query(true); // == { dest : 'aboutus.aspx' }
alert(qs.dest); // == aboutus.aspx
And to parse the query string of current page:-
var $_GET = URI(document.URL).query(true); // ala PHP
alert($_GET['dest']); // == aboutus.aspx
Me too! http://jsfiddle.net/drzaus/8EE8k/
(Note: without fancy nested or duplicate checking)
deparam = (function(d,x,params,p,i,j) {
return function (qs) {
// start bucket; can't cheat by setting it in scope declaration or it overwrites
params = {};
// remove preceding non-querystring, correct spaces, and split
qs = qs.substring(qs.indexOf('?')+1).replace(x,' ').split('&');
// march and parse
for (i = qs.length; i > 0;) {
p = qs[--i];
// allow equals in value
j = p.indexOf('=');
// what if no val?
if(j === -1) params[d(p)] = undefined;
else params[d(p.substring(0,j))] = d(p.substring(j+1));
}
return params;
};//-- fn deparam
})(decodeURIComponent, /\+/g);
And tests:
var tests = {};
tests["simple params"] = "ID=2&first=1&second=b";
tests["full url"] = "http://blah.com/?third=c&fourth=d&fifth=e";
tests['just ?'] = '?animal=bear&fruit=apple&building=Empire State Building&spaces=these+are+pluses';
tests['with equals'] = 'foo=bar&baz=quux&equals=with=extra=equals&grault=garply';
tests['no value'] = 'foo=bar&baz=&qux=quux';
tests['value omit'] = 'foo=bar&baz&qux=quux';
var $output = document.getElementById('output');
function output(msg) {
msg = Array.prototype.slice.call(arguments, 0).join("\n");
if($output) $output.innerHTML += "\n" + msg + "\n";
else console.log(msg);
}
var results = {}; // save results, so we can confirm we're not incorrectly referencing
$.each(tests, function(msg, test) {
var q = deparam(test);
results[msg] = q;
output(msg, test, JSON.stringify(q), $.param(q));
output('-------------------');
});
output('=== confirming results non-overwrite ===');
$.each(results, function(msg, result) {
output(msg, JSON.stringify(result));
output('-------------------');
});
Results in:
simple params
ID=2&first=1&second=b
{"second":"b","first":"1","ID":"2"}
second=b&first=1&ID=2
-------------------
full url
http://blah.com/?third=c&fourth=d&fifth=e
{"fifth":"e","fourth":"d","third":"c"}
fifth=e&fourth=d&third=c

{"grault":"garply","equals":"with=extra=equals","baz":"quux","foo":"bar"}

-------------------

foo=bar&baz=&qux=quux
{"qux":"quux","baz":"","foo":"bar"}
qux=quux&baz=&foo=bar
-------------------
value omit

{"qux":"quux","foo":"bar"} <-- it's there, i swear!
qux=quux&baz=&foo=bar <-- ...see, jQuery found it
-------------------
Here's my version based loosely on Braceyard's version above but parsing into a 'dictionary' and support for search args without '='. In use it in my JQuery $(document).ready() function. The arguments are stored as key/value pairs in argsParsed, which you might want to save somewhere...
'use strict';
function parseQuery(search) {
var args = search.substring(1).split('&');
var argsParsed = {};
var i, arg, kvp, key, value;
for (i=0; i < args.length; i++) {
arg = args[i];
if (-1 === arg.indexOf('=')) {
argsParsed[decodeURIComponent(arg).trim()] = true;
}
else {
kvp = arg.split('=');
key = decodeURIComponent(kvp[0]).trim();
value = decodeURIComponent(kvp[1]).trim();
argsParsed[key] = value;
}
}
return argsParsed;
}
parseQuery(document.location.search);
Following on from my comment to the answer #bobby posted, here is the code I would use:
function parseQuery(str)
{
if(typeof str != "string" || str.length == 0) return {};
var s = str.split("&");
var s_length = s.length;
var bit, query = {}, first, second;
for(var i = 0; i < s_length; i++)
{
bit = s[i].split("=");
first = decodeURIComponent(bit[0]);
if(first.length == 0) continue;
second = decodeURIComponent(bit[1]);
if(typeof query[first] == "undefined") query[first] = second;
else if(query[first] instanceof Array) query[first].push(second);
else query[first] = [query[first], second];
}
return query;
}
This code takes in the querystring provided (as 'str') and returns an object. The string is split on all occurances of &, resulting in an array. the array is then travsersed and each item in it is split by "=". This results in sub arrays wherein the 0th element is the parameter and the 1st element is the value (or undefined if no = sign). These are mapped to object properties, so for example the string "hello=1&another=2&something" is turned into:
{
hello: "1",
another: "2",
something: undefined
}
In addition, this code notices repeating reoccurances such as "hello=1&hello=2" and converts the result into an array, eg:
{
hello: ["1", "2"]
}
You'll also notice it deals with cases in whih the = sign is not used. It also ignores if there is an equal sign straight after an & symbol.
A bit overkill for the original question, but a reusable solution if you ever need to work with querystrings in javascript :)
If you know that you will only have that one querystring variable you can simply do:
var dest = location.search.replace(/^.*?\=/, '');
The following function will parse the search string with a regular expression, cache the result and return the value of the requested variable:
window.getSearch = function(variable) {
var parsedSearch;
parsedSearch = window.parsedSearch || (function() {
var match, re, ret;
re = /\??(.*?)=([^\&]*)&?/gi;
ret = {};
while (match = re.exec(document.location.search)) {
ret[match[1]] = match[2];
}
return window.parsedSearch = ret;
})();
return parsedSearch[variable];
};
You can either call it once without any parameters and work with the window.parsedSearch object, or call getSearch subsequently.
I haven't fully tested this, the regular expression might still need some tweaking...
How about this?
function getQueryVar(varName){
// Grab and unescape the query string - appending an '&' keeps the RegExp simple
// for the sake of this example.
var queryStr = unescape(window.location.search) + '&';
// Dynamic replacement RegExp
var regex = new RegExp('.*?[&\\?]' + varName + '=(.*?)&.*');
// Apply RegExp to the query string
var val = queryStr.replace(regex, "$1");
// If the string is the same, we didn't find a match - return false
return val == queryStr ? false : val;
}
..then just call it with:
alert('Var "dest" = ' + getQueryVar('dest'));
Cheers
I wanted a simple function that took a URL as an input and returned a map of the query params.
If I were to improve this function, I would support the standard for array data in the URL, and or nested variables.
This should work back and for with the jQuery.param( qparams ) function.
function getQueryParams(url){
var qparams = {},
parts = (url||'').split('?'),
qparts, qpart,
i=0;
if(parts.length <= 1 ){
return qparams;
}else{
qparts = parts[1].split('&');
for(i in qparts){
qpart = qparts[i].split('=');
qparams[decodeURIComponent(qpart[0])] =
decodeURIComponent(qpart[1] || '');
}
}
return qparams;
};
