String to object in JS

Question

I have a string as

string = "firstName:name1, lastName:last1";

now I need one object obj such that

obj = {firstName:name1, lastName:last1}

How can I do this in JS?

Answer 1

Your string looks like a JSON string without the curly braces.

This should work then:

obj = eval('{' + str + '}');

Answer 2

If I'm understanding correctly:

var properties = string.split(', ');
var obj = {};
properties.forEach(function(property) {
    var tup = property.split(':');
    obj[tup[0]] = tup[1];
});

I'm assuming that the property name is to the left of the colon and the string value that it takes on is to the right.

Note that Array.forEach is JavaScript 1.6 -- you may want to use a toolkit for maximum compatibility.
