How to remove word before slash using jquery?
/bis/admin
In my case, I want to remove "bis". any help?

You can use the JavaScript split method
var text = "/bis/admin";
var result = text.split("/");
console.log(result[result.length - 1]);
Another example
var text = "/bis/admin/dashboard";
var result = text.split("/");
console.log(result[result.length - 1]);

You could do the following using a regular expression
var el = '/bis/admin';
var newEl = el.replace(/^.*\//, "");
newEl will be 'admin'

You can just do:
let myString = '/bis/admin';
myString.split('/')[myString.split('/').length-1];

var str = "/bis/admin";
var splitStr = str.split("/");
var out = "/" + n[n.length - 1] //Out contains /admin

split string with /.
var strn = "/bis/admin";
console.log(strn.split("/")[2]);
Or you can simply use regex
var strn = "/bis/admin";
console.log(strn.replace(/^\/([^/]*)\//,""));

I have a requirement to remove last n characters from string or remove 'page' from a particular string.
Eg:
var string = 'facebookpage';
Expected output string = 'facebook'
I would like to remove 'page' from the string.
Done it using substring.
var str = "facebookpage";
str = str.substring(0, str.length - 4);
Could you help me to find some better way to do it.

Regex for this:
//str - string;
//n - count of symbols, for return
function(str, n){
var re = new RegExp(".{" + n + "}","i");
return str.match(re);
};
EDIT:
For remove last n characters:
var re = new RegExp(".{" + n + "}$","i");
return str.replace(re, "");
UPDATE:
But use regex for this task, not good way; For example, AVG Runtime for 100000 iterations:
Str length solution = 63.34 ms
Regex solution = 172.2 ms

Use javascript replace function
var str = "facebookpage";
str = str.replace('page','');

You can use this regular expression :
(.*)\\w{4}
code :
var regex =(new RegExp("(.*)\\w{4}"))
val output = regex .exec("facebookpage")
// output is : ["facebookpage", "facebook"]
// output[1] is the Expected output which you want.
Hope this helps.

I need to extract a part of a string. My goal is to extract from this string:
217591953.1396968335.2.2.utmcsr=search_email_alerts|utmccn=(not set)|utmcmd=email
the content between utmcsr= and |
So the output would be : "search_email_alerts".

var str = "217591953.1396968335.2.2.utmcsr=search_email_alerts|utmccn=(not set)|utmcmd=email";
var newStr1 = str.split("utmcsr=");
var newStr2 = newStr1[1].split("|");
var extractedStr = newStr2[0];
The variable extractedStr will be "search_email_alerts".

Use regular expression like following:
var test = "217591953.1396968335.2.2.utmcsr=search_email_alerts|utmccn=(not set)|utmcmd=email";
var result = test.match("/utmcsr=([^|]*)\|/");
alert(result[1]); // result[1] is your desired string

var str = "217591953.1396968335.2.2.utmcsr=search_email_alerts|utmccn=(not set)|utmcmd=email";
match = str.match(/utmcsr=(.*?)\|/);
output = match[1];

var str = "217591953.1396968335.2.2.utmcsr=search_email_alerts|utmccn=(not set)|utmcmd=email"
var result = str.substring(str.indexOf("utmcsr=") + 7,str.indexOf("|"))
Result contains the desired text.

You can do that in two ways
substring
match
Here's how you can do it with regex:
var str= "217591953.1396968335.2.2.utmcsr=search_email_alerts|utmccn=(not set)|utmcmd=email";
var res = str.match(/^.*utmcsr=(.*)\|.*\|.*$/);
res[1]

Here you go -
var str = "217591953.1396968335.2.2.utmcsr=search_email_alerts|utmccn=(not set)|utmcmd=email";
var startIndex = str.indexOf("utmcsr=") + "utmcsr=".length;
var numOfCharsToExtract = str.indexOf("|") - startIndex;
var result = str.substring(startIndex, numOfCharsToExtract);

I am terrible at regex. Please have pity and give me a hand.
I am trying to split a string by the first occurrence of And (case sensitive), into an array with a length of 2. I have no idea were to begin, so can someone help me?
var strArr = "Thing And other thing".split(/magic regex/);
expect(strArr).to.deep.equal(["Thing","And other thing"]);
var strArr = "Thing and other thing".split(/magic regex/);
expect(strArr).to.deep.equal(["Thing and other thing", ""]);
var strArr = "One Thing And other thing And yet another thing".split(/magic regex/);
expect(strArr).to.deep.equal(["One Thing","And other thing And yet another thing"]);
var strArr = "yep, just one thing".split(/magic regex/);
expect(strArr).to.deep.equal(["yep, just one thing", ""]);
UPDATE this is working exactly the way I need it to, but its still ugly:
parser = function(str) {
var spl;
spl = str.split(/\s(?=And )/);
if (spl.length > 1) {
spl = [spl.shift(), spl.join(" ")];
} else {
spl = [str, ''];
}
return spl;
};

There is no need for a regular expression for that. Just get the first index of "And" in the string:
var i = str.indexOf("And");
var strArr;
if (i == -1) {
strArr = [ str ];
} else {
strArr = [ str.substr(0, i), str.substr(i) ];
}

While Guffa's method works, if you end up needing to do this the regex way, the following will work (via a positive lookahead):
var str = "Thing And other thing";
var spl = str.split(/\s(?=And\s)/);
if (spl.length > 1)
spl = [spl.shift(), spl.join(" ")];
To test:
alert(JSON.stringify(spl));
jsFiddle
Updated to ensure it splits on [space]And[space]

I suggest doing a simple split then checking if the array has one or two
strArr.split("And", 2).length;

var s='Color sentence';
My task is to do something on every first consonant . For example in this sencente "Color sentence" i need to color letters C,L,R,S,N,E,C etc.
But i need code to count every first letter .Help(I'm newbie.) ?

Assuming you're going to insert that string as HTML ?
var s = 'Color sentence';
var a = s.split(' ');
for (var i=0; i<a.length; i++) {
a[i] = '<span style="color:red">' + a[i].charAt(0) + '</span>' + a[i].slice(1);
}
var s = a.join(' ');
FIDDLE
for every other letter in the string, you'd do:
var s = 'Color sentence';
var a = s.split('');
for (var i=0; i<a.length; i++) {
if (i%2)
a[i] = '<span style="color:red">' + a[i].charAt(0) + '</span>' + a[i].slice(1);
}
var s = a.join('');
FIDDLE

You can simply call
s[0] //to get the first character in the string.
var x = "Hello";
var y = x[0];
alert(y);
Output: "H"

To do somewthing with every other character, you can use a regular expression to put an HTML element around them so that you can style them:
s = s.replace(/(^|.)(.)/g, '$1<span>$2</span>');
Demo: http://jsfiddle.net/Guffa/vLEhh/
Regular expression explanation:
(^|.) - catches the beginning of the string or one character into $1
(.) - catches one character into $2
So, the expression matches either the start of the string or one character, followed by another character. The first match in the string will be the first character, from then on it will match two characters at a time.
