Convert a string to object javascript/jquery

Question

Id: {
    editable: false,
    nullable: true
},
CustomerID: {
    editable: true,
    type: Integer
},
CompanyName: {
    editable: true,
    type: String
},
ContactName: {
    editable: true,
    type: String
}

Hi, is there a way in javascript or jquery where I could convert this String into an Object?

Thanks.

JSON doesn't support function values (like String or Integer. also not supported in all browsers (versions) — DoronG

That string should be dynamic, I read fields from a database table — confused

If that is strictly the format of the string then it's invalid JSON. However, you can get around this issue with judicious use of eval():

eval('myobj = {' + stringifiedObject + '};');

As clarification, the reason you cannot use JSON.parse() here is that the JSON specification requires that all keys are quoted.

JSON.parse('{ ID: 1 }');   // Generates an exception: Invalid character
JSON.parse('{ "ID": 1 }'); // Returns object: { ID: 1 }

Based on the @Phylogenesis answer but without the eval.

Wrap the -almost- object and then run a JSON.parse.

var myObj;

stringifiedObject = '{' + stringifiedObject + '}';
myObj = JSON.parse(stringifiedObject);

Note: If you don't know the origin (or format) of the string you'd like to pase, then you can wrap the JSON.parse line between a try..catch() statement.

Unfortunately, this won't work. The JSON specification requires that key names are quoted: { "Id": { "editable": false, "nullable": true }, ...}. Running JSON.parse() on your example will generate an exception.

@Phylogenesis you're right, your answer is definitely better then.

I would use a combination of both existing answers

var new_string = JSON.parse((string.trim().charAt(0)!=='{')?('{'+string+'}'):string);

Assuming string is your input, and new_string is your output

This may work for you,

var mystring="[Id: {
    editable: false,
    nullable: true
},
CustomerID: {
    editable: true,
    type: Integer
},
CompanyName: {
    editable: true,
    type: String
},
ContactName: {
    editable: true,
    type: String
}]";

var obj1 = JSON.parse(mystring);

OR 

var obj2= eval('(' + mystring+ ')');
