Set the JavaScript array variable equal to the value of the input text field containing a JavaScript array

Currently, I am attempting to populate location data for Google Maps initialization. I have tried assigning an HTML input field with a JavaScript array format in order to use it for Google Maps, but unfortunately, my attempts have been unsuccessful. Here is the code snippet:

      <input id="a" name="a" value='["WAPDA Town, Lahore, Pakistan","31.4311985","74.26435820000006","1"],["Johar Town, Lahore, Pakistan","31.469693","74.27284610000004","2"],'>

Afterwards, I call it within my script to initialize it for locations.

 var location = '[' + document.getElementById('a').value + ']';

However, I am not getting the desired result and realize that I am doing something wrong. Can anyone suggest the proper way to initialize it?

Answer №1

Give it a shot (I took out the last comma from your input)

var location = JSON.parse(`[${a.value}]`);

console.log(location);
 <input id="a" name="a" value='["WAPDA Town, Lahore, Pakistan","31.4311985","74.26435820000006","1"],["Johar Town, Lahore, Pakistan","31.469693","74.27284610000004","2"]'>
