Finding variables dynamically

Question

I have 3 defined variables.

var age = 25;
var name = 'vincent';
var work = 'painter';

below function required to assign corresponding values to the variables.

function assign(_data){
 //_data contains "age_25" and it might be "Name_Raja" 
 //this can be any one of the three variables.
}

How to identify the corresponding variable from the data?

• Ronen Ness: is _data a list? why not a dictionary?

Answer 1

Use indexOf of to identify what data contains

var name = '',
 age = 0,
 work = '';
function assign(_data) {
 _data = _data.toLowerCase();
 if (_data.indexOf('name_')) {
 name = _data.split('_')[1];
 } 
 else if (_data.indexOf('age_')) {
 age = parseInt(_data.split('_')[1]);
 } 
 else if (_data.indexOf('work_')) {
 work = _data.split('_')[1];
 }
}

Answer 2

function assign(_data){
 window[_data.split("_")[0]] = _data.split("_")[1];
}

This assigns the value of the corresponding key.
