How to convert Javascript string of array to array?

Question

I have a data-type element for each option in select box. When I select an option I get the data-type as "[{:type=>"textbox", :label=>"Age"}]" (string of array of hashes). I want to convert this to array of hashes. I searched in google but couldn't get any. Can anyone help.

I tried replace as well, str.replace('"[', '[').replace(']"' , ']'); but didnt get result. I want this in Javascript.

but that is not coming in JSON format. SO am not able to acheive that. — Kranthi

Is that what the value actually looks like? What kind of syntax is that? It's not JSON and it doesn't look like PHP either. Sounds to me like you need a bonafide parser, and that may be outside the scope of an SO question. — JLRishe

Works for this one sample anyway:

var a = '[{:type=>"textbox", :label=>"Age"}]';

var b = JSON.parse(a.replace(/:/g, '"').replace(/=>/g,'":'));

console.table(b);
