There is a string that resembles the following pattern:
var stringArray = "[[1,2,3,4],[5,6,7,8]]"
The objective is to use Javascript to convert it to the following format:
var actualArray = [[1,2,3,4],[5,6,7,8]]
What would be the method to accomplish this task?
Your data is formatted in JSON. To parse it, you can utilize any JSON parsing tool or library. For instance, you can use JSON.parse(stringArray) (source).
Below is an example that demonstrates the use of JSON.parse:
var stringArray = "[[1,2,3,4],[5,6,7,8]]";
var parsedArray = JSON.parse(stringArray);
$('#first').html(parsedArray[0].toString());
$('#second').html(parsedArray[1].toString());<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
First element: <span id="first"></span><br>
Second element: <span id="second"></span>Another approach is using the eval function (guide), but it is recommended to avoid this method whenever possible due to security risks and decreased performance. More information on that can be found here.
Nevertheless, here is an example using the eval method:
var stringArray = "[[1,2,3,4],[5,6,7,8]]";
var parsedArray = eval(stringArray);
$('#first').html(parsedArray[0].toString());
$('#second').html(parsedArray[1].toString());<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
First element: <span id="first"></span><br>
Second element: <span id="second"></span>My URL is too long with multiple queries, such as /projects/1/&category=Branding&title=Mobile+App&about=Lorem+ipsum+Lorem+. I just want to simplify it to /projects/1/mobile-app. I've been struggling to fix this for a week. While I found so ...
