how to convert ["one","two","three","four "] to [one,two,thee,four] as array in jquery or javascript

Question

I have a scenario. I will get all the data from service in the below shown array format. but I need to convert that to by removing them as strings

var array1 = ["one","two","three","four"]

var array1 =  [one,two,thee,four]

array contains strings to variables of the array.

array accept object and if you don't want `"one","two"..` and `one,two..` then `one`, `two` should be a variable or object. — Bhushan Kawadkar, Nov 04 '14 at 06:30

Try,

var array1 = ["one","two","three","four"].map(function(val){ return window[val]; });

But the new array would contain the values of the variables not the variable itself.

@TheParamagneticCroissant look up basically starts from local scope to the global scope. – Rajaprabhu Aravindasamy Nov 04 '14 at 06:32
just replace `window` with `this` and it does :) – VDP Nov 04 '14 at 06:41
@elclanrs Yes.. Just now realised that.. thought in a different way. Ok then to overcome that then we must use eval() at this context. Am i right.?? – Rajaprabhu Aravindasamy Nov 04 '14 at 06:42
@RajaprabhuAravindasamy: I'd have to know why OP wants to do this to tell what's the right solution; both this and `eval` are questionable solutions to a problem that shouldn't exist. – elclanrs Nov 04 '14 at 06:43
yes it does. I ment like [this](http://jsfiddle.net/Vandeplas/m3m0xrs2/) It's just basic scoping – VDP Nov 04 '14 at 06:47

There are no double quotes in that array. The quotes just delimit the string literals, when they are parsed into strings they don't have quotes in them.

If you wanted to remove all the quotes from a string which actually had some in it:

str = str.replace(/"/g, "");  // RegEx to match `"` characters, with `g` for globally (instead of once)

You could do that in a loop over an array:

for (var i = 0; i < array1.length; i++) {
    array1[i] = array1[i].replace(/"/g, "");
}
