Question

Can I write a function that takes in a string made up of a number or “pairs” separated by “|” characters and produces an object as shown below? Each pair has its two components separated internally with commas.

Example:

objectify("a,dog|b,cat|z,rat")  -->  {a: "dog", b: "cat", z: "rat"}
objectify("one,uno|two,dos")    -->  {one: "uno", two: "dos"}

Thanks!

Answer 1

function objectify(str) {
    var obj = {},
        arr = str.split('|');
    for (i=0; i<arr.length;i++) {
        var parts = arr[i].split(',');
        obj[parts[0]] = parts[1];
    }
    return obj;
}

FIDDLE

Create an empty object, split the string on | and iterate over the parts, split again on comma, and use the result as key/value pairs in the object, and return the object when done.
