Split a string only the at the first n occurrences of a delimiter

Question

I\'d like to split a string only the at the first n occurrences of a delimiter. I know, I could add them together using a loop, but isn\'t there a more straight forward appr

Answer 1

Hi there i had the same problem wanted to split only several times, couldnt find anything so i just extended the DOM - just a quick and dirty solution but it works :)

String.prototype.split = function(seperator,limit) {
    var value = "";
    var hops  = [];

    // Validate limit
    limit = typeof(limit)==='number'?limit:0;

    // Join back given value
    for ( var i = 0; i < this.length; i++ ) { value += this[i]; }

    // Walkthrough given hops
    for ( var i = 0; i < limit; i++ ) {
        var pos = value.indexOf(seperator);
        if ( pos != -1 ) {
            hops.push(value.slice(0,pos));
            value = value.slice(pos + seperator.length,value.length)

        // Done here break dat
        } else {
            break;
        }
    }
    // Add non processed rest and return
    hops.push(value)
    return hops;
}

In your case would look like that

>>> "Split this, but not this".split(' ',2)
["Split", "this,", "but not this"]
