下划线前后的JavaScript匹配

Question

I have an array in JavaScript. Items in the array are like below:

var people = new Array("michael_51", "mark_57", "graham_44", "paul_22");

I would really like to split the elements before and after the underscore and then use them in a loop.

start loop...
(1st Match) - (2nd Match)
end loop...

First in the loop match would be (michael) and second would be (51) etc.

Many thanks.

Answer 1

Regex is not really necessary (apart from the split ):

var people = new Array("michael_51", "mark_57", "graham_44", "paul_22");

for(var i = 0; i < people.length; i++) {
    var data = people[i].split("_");
    alert("(1st Match): "+data[0]+" - (2nd Match): "+data[1]);
}

Answer 2

var people = new Array("michael_51", "mark_57", "graham_44", "paul_22");

for (p in people) {
    console.log(people[p].split('_'));
}

Answer 3

var i, cleanPeople = [];
for (i = 0; i < people.length; i++) {
    cleanPeople.push(people[i].split('_'));
}
