Replace every nth character from a string

rated 0 times [ 168] [ 3] / answers: 1 / hits: 18228 / 9 Years ago, sun, august 16, 2015, 12:00:00

I have this JavaScript:

var str = abcdefoihewfojias.split('');



for (var i = 0; i < str.length; i++) {

    var xp = str[i] = |;

}

alert( str.join() );

I aim to replace every fourth letter in the string abcdefoihewfojias with |, so it becomes abc|efo|....etc,but I do not have a clue how to do this.

To support re-usability and the option to wrap this in an object/function let's parameterise it:

var str = abcdefoihewfojias.split('');

var nth = 4; // the nth character you want to replace

var replaceWith = | // the character you want to replace the nth value

for (var i = nth-1; i < str.length-1; i+=nth) {

    str[i] = replaceWith;

}

alert( str.join() );
