convert array with strings of minute format to seconds format

Question

["4", "5.67", "1:45.67", "4:43.45"]

I have this string array and i want to convert all of the strings to numbers with seconds format so it will become something like this

[4, 5.67, 105.67, 283.45]

how can i do it?

function hmsToSecondsOnly(str) {
    var p = str.split(':'),
        s = 0, m = 1;

    while (p.length > 0) {
        s += m * parseInt(p.pop(), 10);
        m *= 60;
    }

    return s;
}

I found this but it seems to only work in MM:SS format like 1:40 but i want convert strings in x:xx.xx format

You can try using map() like the following way:

 var data = ["4", "5.67", "1:45.67", "4:43.45"]; data = data.map(function(item){ //split to get the hour var a1 = item.split(':'); //split to get the seconds var a2 = item.split('.'); //check the length if(a1.length > 1){ //split to get minutes var t = a1[1].split('.'); //calculate, cast and return return +((a1[0]*60 + +t[0]) + '.' + a2[a2.length - 1]); } else return +item; }); console.log(data);

You could map the formatted time values.

 const data = ["4", "5.67", "1:45.67", "4:43.45"], result = data.map(time => time.split(':').map(Number).reduce((m, s) => m * 60 + s) ); console.log(result);

Another simple solution with RegEx.

 const input = ["4", "5.67", "1:45.67", "4:43.45"] const result = input.map(ele => ele.replace(/^(\d+):(\d+[.]\d*)$/, (m, g1, g2) => `${g1 * 60 + parseFloat(g2)}`)); console.log(result)
