Split a variable in js or jquery

Question

Hi I have some vars like this:

var a = Base-Shirt_Stripe.jpg
var b = Closed-Flatknit-Collar_Stripe.png

How do i create two new vars like:

var c = Base-Shirt
var d = Stripe

or

var e = Closed-Flatknit-Collar
var f = Stripe

basically split at the _ remove the _ and remove the extension.

Answer 1

//for example, we take a
var a = 'Base-Shirt_Stripe.jpg';

//then we take the part of a before the dot
//and split between `_`
//split returns an array
var split = a.substring(0,a.indexOf('.'))
             .split('_');

//split is an array, so we use indices to indicate which
console.log(split[0]); //Base-Shirt
console.log(split[1]); //Stripe

Sample here . You can do the same for your b

Answer 2

You need to make them strings to start with, then use String.split() to split the string into an array of the different parts.

jsFiddle

var a = "Base-Shirt_Stripe.jpg"
var b = "Closed-Flatknit-Collar_Stripe.png"

var aSplit = a.substr(0, a.lastIndexOf('.')).split('_');

var c = aSplit[0];
var d = aSplit[1];

var bSplit = b.substr(0, b.lastIndexOf('.')).split('_');

e = bSplit[0];
f = bSplit[1];

You could also take the removal of the extension out into its own function using String.lastIndexOf() and String.substr() .

function removeExtension(file) {
    return file.substr(0, file.lastIndexOf('.'));
}

Answer 3

may be you could do like

var a = "Base-Shirt_Stripe.jpg"
var k = a.replace(/(\.\w*)$/g, "").split("_");

alert(k[0]);
alert(k[1]);

here is the fiddle

Answer 4

//Javascript Split can divide it into parts. Javascript Split return type is array.'

 //e g.

var a = Base-Shirt_Stripe.jpg
var parts = a.split('_');

 console.log(parts[0]);
    //output
    " Base-Shirt "

 //parts[0] contain base-shirt and    parts[1]   contain Stripe.jpg.
