Change data inside string with box brackets

I have a string
garments[0][1]; // The 0 and 1 can be other numbers
I need to replace the data inside the second and the third box brackets.
[0] and [1]
So that it can be
garments[4][6]
Please let me know your suggestions when you get a chance, thank you.

You can try that:
var string = 'garments[' + 4 + '][' + 6 + ']'; //in your onClick function
//To increment dynamically:
var string = 'garments[' + i + '][' + j + ']'; //i and j being variables incrementing in your loops/treatments
Update to address comments:
If you want to break "garnments[0][1]" into "garnments",0 and 1 you can do the following:
var string = "garnments[0][1]";
string = string.split('['); //string = [["garnments"],["0]"],["1]"]]
string[1].replace(']','');
string[2].replace(']',''); //string = [["garnments"],["0"],["1"]]
You can then change values and rebuild your string for further use.
It is a bit brutal though. You can use RegExp as showed by #Diego

You can use String.prototype.replace()
'garments[0][1]'.replace('[0]','[4]').replace('[1]','[6]')

For any possible string with ***[m][n] format:
Function SetNewValues(testString, n, m)
{
var keyWordLengh = testString.indexOf("[");
return testString.substring(0,keyWordLengh) + "[" + n.toString() + "][" + m.toString() + "]";
}
Where:
testString is entire string to work on, like "something[342][345]"
n,m are values to be put inside brackets :)

This would be my approach.
var string = "['foobar'][2][12]";
var match =
/\[([^\]]+)\](?:\[(\d+)\])(?:\[(\d+)\])/g
.exec(string);
console.log(match);

Adding the single string quote for value inside variable using Javascript

I have a variable, before I use that variable,I need to add string quotes to the value/data which is inside the variable using JavaScript need help
//i am getting like this //
var variable=king;
//i want to convert it with single quote//
variable=variable;
but i need the data inside variable should be in a single quotation.

You can concatenate the variable with your quotes like :
function addQuotes(value){
var quotedVar = "\'" + value + "\'";
return quotedVar;
}
And use it like :
var king = addQuotes('king');
console.log will display :
'king'
Edit : you can try it in the chrome/firefox console, I did it and it works perfectly when copy/paste from here.

var x = 'abc';
var sData = "\'" + x +"\'";
// sData will print "'abc'"

var x = 'pqr';
var sData = "\'" + x +"\'";
// sData will print "'abc'"

1) You can use doublequotes
var variable = "'" + variable + "'";
2) ... or You can escape single quote symbol with backslash
var variable = '\'' + variable + '\'';

How can I change the text in just a part of my string with javascript?

I have a javascript string that contains the following:
data-href="/Admin/Edit?pk=0001I&rk=50050055"
How can I change this string so the value of rk is changed to a value held in the string newRowKey? Not sure if it helps but the data format always looks like this with the rk followed by an = and then terminated with the "

datahref="/Admin/Edit?pk=0001I&rk=50050055";
to change it if your building the URL
datahref="/Admin/Edit?pk=0001I&rk="+ newRowKey;
or replace it if you know the existing value
datahref.replace("50050055", newRowKey);
if you do not know the value of rk, but you know its last in the URL, you could use indexOf to find it.
datahref = datahref.substring(0,datahref.indexOf("rk=")+3) + newRowKey;

Maybe you want a regular expression to replace that rk.
newRowKey = 'XXXXXX'
s = 'Edit?pk=0001I&rk=50050055';
s2 = s.replace(/(.*;)(rk=)(.*)(&|)/, '$1$2' + newRowKey)
alert( s + "\n" + s2 );
//2nd test
s = 'Edit?pk=0001I&rk=50050055&';
s2 = s.replace(/(.*;)(rk=)(.*)(&|)/, '$1$2' + newRowKey)
alert( s + "\n" + s2 );
​demo: http://jsfiddle.net/fedmich/g3TjE/

data_href.replace(/rk=.*$/,'rk=' + newRowKey);

Regular expression for replacing string with javascript

I need help in writing regular expression:
part of my string is fixed and another part of its variable.
only if fixed AND variable string exist i need to alter the string other wise no.
Fixed string:example: AA.BBB.COM
Variable string (may or mayn't exist ): US, but if exist it will be always two letter string with any combination of letter.
In below string if I have variable two letter string exist I want to append “.new”
1 ) https://XY**.US**.AA.BBB.COM
Output: https:// XYZ12**.US.NEW**.AA.BBB.COM
2 ) https://XY.UK.AA.BBB.COM
Output: https:// XYZ12.UK.NEW.AA.BBB.COM
3) https://XY.AA.BBB.COM (no variable string so no change)
Output: https:// XY.AA.BBB.COM
Thanks for your help .

Something like the following should get you started, there are other methods. Splitting and parsing might suit better depending on your real requirements:
var s = 'https://XY.US.AA.BBB.COM';
var t = 'https://XY.UK.AA.BBB.COM';
var u = 'https://XY.AA.BBB.COM';
var re = /(\.)(UK|US)(\.)/;
alert(
s.replace(re, '$1' + '$2' + '.NEW' + '$3') + '\n' +
t.replace(re, '$1' + '$2' + '.NEW' + '$3') + '\n' +
u.replace(re, '$1' + '$2' + '.NEW' + '$3')
);

Removing %20 value from get method

Removing %20 in get method?
var c=new Array(a);
(eg: a={"1","2"}) window.location="my_details.html?"+ c + "_";
and in my_details.html :
var q=window.location.search;
alert("qqqqqqqqqqqqq " + q);
var arrayList = (q)? q.substring(1).split("_"):[];
var list=new Array(arrayList);
alert("dataaaaaaaaaaaa " + list + "llll " );
and in "list" its dusplaying me "1%202";
How can I remove this %20 =space value ??
Thanks

just use this:
alert("dataaaaaaaaaaaa " + decodeURIComponent(list) + "llll " );
This should decode the %20 to space
look here: http://www.w3schools.com/jsref/jsref_decodeURIComponent.asp

If there is a space in the parameter(s), then the %20 (URL Encoding) is necessary. You cannot pass a space in a GET request.
If you need to avoid this, use POST.

As far as I can see the problem is being introduced at this line:
window.location="my_details.html?"+ c + "_";
This could be written as:
window.location="my_details.html?"+ c.toString() + "_";
The default .toString() of a JavaScript Array would be to use a delimiter of ,, i.e.
var str = ["1", "2", "3"].toString(); // 1,2,3
In you example it appears that the delimiter being used is a space. This would have been changed by something changing the default behaviour of .toString() on the Array.prototype. Try using the following:
window.location="my_details.html?"+ c.join(",") + "_";

Better to use replace() method to replace %20 to space
list.replace("%20"," ");
