You need to use JSON.parse()

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse

It will make a javascript object or array out of string.

var getedTags = JSON.parse(data)

To reverse this, you can use JSON.stringify() https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify

It will turn your array or javascript object into a string.

You should convert the data you get from server into array. I presume the data type you are getting is JSON.

You can do JSON.parse(data) to convert in Object.

You can use JSON.parse() from parse string to object. 

var getedTags = [];
$.get(getTagurl,
function (data) {
    getedTags = JSON.parse(data);
});
