I have this string

'john smith~123 Street~Apt 4~New York~NY~12345' 

Using JavaScript, what is the fastest way to parse this into

var name = "john smith"; var street= "123 Street"; //etc...

With JavaScript’s String.prototype.split function:

var input = 'john smith~123 Street~Apt 4~New York~NY~12345'; var fields = input.split('~'); var name = fields[0]; var street = fields[1]; // etc. 

According to ECMAScript6 ES6, the clean way is destructuring arrays:

const input = 'john smith~123 Street~Apt 4~New York~NY~12345'; const [name, street, unit, city, state, zip] = input.split('~'); console.log(name); // john smith console.log(street); // 123 Street console.log(unit); // Apt 4 console.log(city); // New York console.log(state); // NY console.log(zip); // 12345

You may have extra items in the input string. In this case, you can use rest operator to get an array for the rest or just ignore them:

const input = 'john smith~123 Street~Apt 4~New York~NY~12345'; const [name, street, ...others] = input.split('~'); console.log(name); // john smith console.log(street); // 123 Street console.log(others); // ["Apt 4", "New York", "NY", "12345"]

I supposed a read-only reference for values and used the const declaration.

Enjoy ES6!

You don't need jQuery.

var s = 'john smith~123 Street~Apt 4~New York~NY~12345'; var fields = s.split(/~/); var name = fields[0]; var street = fields[1]; 

Even though this is not the simplest way, you could do this:

var addressString = "~john smith~123 Street~Apt 4~New York~NY~12345~", keys = "name address1 address2 city state zipcode".split(" "), address = {}; // clean up the string with the first replace // "abuse" the second replace to map the keys to the matches addressString.replace(/^~|~$/g).replace(/[^~]+/g, function(match){ address[ keys.unshift() ] = match; }); // address will contain the mapped result address = { address1: "123 Street" address2: "Apt 4" city: "New York" name: "john smith" state: "NY" zipcode: "12345" } 

Update for ES2015, using destructuring

const [address1, address2, city, name, state, zipcode] = addressString.match(/[^~]+/g); // The variables defined above now contain the appropriate information: console.log(address1, address2, city, name, state, zipcode); // -> john smith 123 Street Apt 4 New York NY 12345 

You'll want to look into JavaScript's substr or split, as this is not really a task suited for jQuery.

If Spliter is found then only

it will Split it

else return the same string

function SplitTheString(ResultStr) { if (ResultStr != null) { var SplitChars = '~'; if (ResultStr.indexOf(SplitChars) >= 0) { var DtlStr = ResultStr.split(SplitChars); var name = DtlStr[0]; var street = DtlStr[1]; } } } 

well, easiest way would be something like:

var address = theEncodedString.split(/~/) var name = address[0], street = address[1] 

You can use split to split the text.

As an alternative, you can also use match as follow

var str = 'john smith~123 Street~Apt 4~New York~NY~12345'; matches = str.match(/[^~]+/g); console.log(matches); document.write(matches);

The regex [^~]+ will match all the characters except ~ and return the matches in an array. You can then extract the matches from it.

split() method in JavaScript is used to convert a string to an array. It takes one optional argument, as a character, on which to split. In your case (~).

If splitOn is skipped, it will simply put string as it is on 0th position of an array.

If splitOn is just a “”, then it will convert array of single characters.

So in your case:

var arr = input.split('~'); 

will get the name at arr[0] and the street at arr[1].

You can read for a more detailed explanation at Split on in JavaScript

Something like:

var divided = str.split("/~/"); var name=divided[0]; var street = divided[1]; 

Is probably going to be easiest

Zach had this one right.. using his method you could also make a seemingly "multi-dimensional" array.. I created a quick example at JSFiddle

// array[0][0] will produce brian // array[0][1] will produce james // array[1][0] will produce kevin // array[1][1] will produce haley var array = []; array[0] = "brian,james,doug".split(","); array[1] = "kevin,haley,steph".split(","); 

This string.split("~")[0]; gets things done.

source: String.prototype.split()

Another functional approach using curry and function composition.

So the first thing would be the split function. We want to make this "john smith~123 Street~Apt 4~New York~NY~12345" into this ["john smith", "123 Street", "Apt 4", "New York", "NY", "12345"]

const split = (separator) => (text) => text.split(separator); const splitByTilde = split('~'); 

So now we can use our specialized splitByTilde function. Example:

splitByTilde("john smith~123 Street~Apt 4~New York~NY~12345") // ["john smith", "123 Street", "Apt 4", "New York", "NY", "12345"] 

To get the first element we can use the list[0] operator. Let's build a first function:

const first = (list) => list[0]; 

The algorithm is: split by the colon and then get the first element of the given list. So we can compose those functions to build our final getName function. Building a compose function with reduce:

const compose = (...fns) => (value) => fns.reduceRight((acc, fn) => fn(acc), value); 

And now using it to compose splitByTilde and first functions.

const getName = compose(first, splitByTilde); let string = 'john smith~123 Street~Apt 4~New York~NY~12345'; getName(string); // "john smith" 

Try in Plain Javascript

 //basic url= var ar= [url,statu] = window.location.href.split("=");

Since the splitting on commas question is duplicated to this question, adding this here.

If you want to split on a character and also handle extra whitespace that might follow that character, which often happens with commas, you can use replace then split, like this:

var items = string.replace(/,\s+/, ",").split(',') 

This isn't as good as the destructuring answer, but seeing as this question was asked 12 years ago, I decided to give it an answer that also would have worked 12 years ago.

function Record(s) { var keys = ["name", "address", "address2", "city", "state", "zip"], values = s.split("~"), i for (i = 0; i<keys.length; i++) { this[keys[i]] = values[i] } } var record = new Record('john smith~123 Street~Apt 4~New York~NY~12345') record.name // contains john smith record.address // contains 123 Street record.address2 // contains Apt 4 record.city // contains New York record.state // contains NY record.zip // contains zip 

Use this code --

function myFunction() { var str = "How are you doing today?"; var res = str.split("/"); }
