Replace string in javascript array

Question

I have an array in javascript. This array has strings that contains commas (\",\"). I want all commas to be removed from this array. Can this be done?

Answer 1

Yes.

for(var i=0; i < arr.length; i++) {
 arr[i] = arr[i].replace(/,/g, '');
}

Answer 2

you can also do in inline in a shorter syntax

array = array.map(x => x.replace(/,/g,""));

Answer 3

You can use array.map or forEach. According to our scenario, array.map creates or given a new array. forEach allows you to manipulate data in an already existing array. Today I used it like this for me.

document.addEventListener("DOMContentLoaded", () => {
    // products service
    const products = new Products();
    // get producsts from API.
    products
    .getProducts()
    .then(products => {
        /*
        raw output of data "SHEPPERD'S SALLAD" to "SHEPPERDS SALLAD"
        so I want to get an output like this and just want the object 
        to affect the title proporties. other features should stay 
        the same as it came from the db.
        */ 
        products.forEach(product => product.title = product.title.replace(/'/g,''));
        Storage.saveProducts(products);
    });
});

Answer 4

You can simply do:

array = ["erf,","erfeer,rf","erfer"];
array = array.map(function(x){ return x.replace(/,/g,"") });

Now Array Becomes:

["erf", "erfeerrf", "erfer"]

Answer 5

Given the required string in variable s :-

var result = s.replace(/,/g, '');

Answer 6

Sure -- just iterate through the array and do a standard removal on each iteration.

Or if the nature of your array permits, you could first convert the array to a string, take out the commas, then convert back into an array.
