Loading string format arrays into an array

Question

I am getting a set of Arrays in string format from Database like

["#464b4e","#7ebcbd"], ["#747493","#f5f6f7"], ["#58383c","#8d8566"]

Now I need to load them into array to make an array of arrays. Using this code

        let imgIndicators = [];
        imgIndicators.push( obj[i]['dicatorsbg']);
        console.log(imgIndicators);

is creating an array like

["["#464b4e","#7ebcbd"], ["#747493","#f5f6f7"], ["#58383c","#8d8566"]"]

which as you can see is big long string item, so I tried splitting the data by , like

imgIndicators.push( obj[i]['dicatorsbg'].split(','));

This time code is accepting all , and creating an array of 6 string elemet like

 ["["#464b4e"", ""#7ebcbd"]", " ["#747493"", ""#f5f6f7"]", " ["#58383c"", ""#8d8566"]"]

How can I fix this code to create something like this?

 [
   ["#464b4e", "#7ebcbd"], 
   ["#747493", "#f5f6f7"], 
   ["#58383c", "#8d8566"]
]

do you get a JSON string or some other format? where is 'dicatorsbg' coming from? — Nina Scholz

I guess it is JSON string because I have this in my PHP side echo json_encode($products); — Mona Coder

Since it's a JSON (assuming $product is an array-like or object-like in php), please just follow this: 1) Post an example of the JSON, even the original one, if you can share it. 2) Post the expected result. It's not a great deal, it's just matter of parsing the JSON string, acquiring the desired value and pushing it to a new array, that's it. — briosheje

does JSON.parse works for you or just taking the string as is into the javascript part? - with maybe wrapped into brackets? but if the last part is necessary, you do not have a valid JSON. — Nina Scholz

If you are really sure that the format will be correct, you can try:

imgIndicators = JSON.parse("[" + obj[i]['dicatorsbg'] + "]");

Its easy , You have to use JSON.parse() as shown below, shall give you your required result.

//your db output string 
var yourStringArray = '["#464b4e","#7ebcbd"], ["#747493","#f5f6f7"], ["#58383c","#8d8566"]' ; 

// the array you want
var requiredArray = JSON.parse("[" + yourStringArray + "]");
