How to remove a part of all strings in an array in javascript?

Question

I want split array value .

for example

gUser[1] = CAR.BENZ.CCLASS.1962

gUser[2] = CAR.PORSCHE.911.2001

I want get string only BENZ.CLASS.1962 and PORSCHE.911.2001

How to split array value on java script?

@update.

not always CAR string. so, not use substring.

Answer 1

You can use map to access each string in array then use replace. Use a regex to match string before '.' and replace only the first match, like this:

  var gUser = ['CAR.BENZ.CCLASS.1962', 'CAR.PORSCHE.911.2001']; var gUserModified = gUser.map(function(v){ return v.replace(/[^\\.]+\\./, ''); }); console.log(gUserModified); 

Answer 2

Split it with dot then slice it and join it with dot

 var gUser =[]; gUser[1] = "CAR.BENZ.CCLASS.1962"; gUser[2] = "CAR.PORSCHE.911.2001"; console.log(gUser[1].split('.').slice(1).join('.')); console.log(gUser[2].split('.').slice(1).join('.')); 

Answer 3

From your question, it's not clear if the array is a string array

If it is a string array you can do:

ES6+: gUser.map((user)=>{return user.split("CAR.")[1]})

ES5: gUser.map(function(user){return user.split("CAR.")[1]});

Answer 4

The below code is not tested but should probably work, with maybe minor tweaks

 var splitStr = '' var correctCarArr = [] for(let i = 0; i < gUser.length; i++){ splitStr = gUser[i].split('.') let temp = '' for(let j = 1; j < splitStr.length; j++){ temp += splitStr[j] } correctCarArr.push(temp) } 

Answer 5

 var gUser = []; gUser[1] = "CAR.BENZ.CCLASS.1962"; var gu1 = gUser[1].split("."); gu1.shift(); console.log(gu1.join(".")); 

Answer 6

Its easier split then shift the array to remove the first item like this:

 gUser = ["CAR.BENZ.CCLASS.1962"]; var benz = gUser[0].split("."); benz.shift(); alert(benz.join('.')); 

There are other options from shift like slice(1) but In terms of performance, shift is apparently faster https://jsperf.com/shift-pop-vs-slice/4

Answer 7

So here is the way without using any regex by only using string and array methods.

 const gUser = ['CAR.BENZ.CCLASS.1962', 'CAR.PORSCHE.911.2001', 'XYZAB.PORSCHE.YSA.2021'] for (let i = 0; i < gUser.length; i++) { console.log('Required String: ', gUser[i].split('.').slice(1).join('.')); } 

What we do is, we split the string into parts where . is encountered.

gUser[0].split('.') returns ['CAR', 'BENZ', 'CCLASS', '1962']

Later when slice(1) is called, the zeroth element of array is chopped off and will return ['BENZ', 'CCLASS', '1962']

And finally using join('.') , we merge the array elements to a single string with a . between each element, which returns BENZ.CCLASS.1962

Hope this helps! :)

Something Like This

`for(let index = 0; index < gUser.length; index++) {
    console.log(gUser[index].split('.').splice(0, 1).join('.'));
}`

I haven't tested it. Please check and let me know
