How to split comma separated string using JavaScript? [duplicate]
(4 answers)
Closed 3 years ago.
I am new to stack overflow learning javascript and programming.
I have a problem that i am stuck while learning and thinking any help on this question will be
useful for me thanks and the question is:
Example i have a variable a in the code below and i want to convert it to an array in javascript
var a = ["baby,cat,dog"]
i wanted it to be
a = ["baby","cat","dog"].
Use String.prototype.split() as below
var a = ["baby,cat,dog"];
a = a[0].split(',');
console.log(a);
You could take the array and map the splitted values and get a flat array back.
var array = ["baby,cat,dog"];
result = array.flatMap(s => s.split(','));
console.log(result);

Parse JSON in JavaScript? [duplicate]

I want to turn this into an array
"["65747add-afd2-45b5-92e0-150bbe40e6d9", "9c247ea5-6b81-4f47-a50c-42367dedd50b", "c1555363-aca9-4e04-8844-e0180397c72e"]"
I am getting it from the page like this:
$('#layout-uuids').text()
Is there away to just get it as an array or do I need to turn the string into an array somehow?
Thanks!
That string looks like JSON. If it is indeed JSON, all you need is JSON.parse():
var someArray = JSON.parse($('#layout-uuids').text());

Convert a multidimensional javascript array to JSON?
(9 answers)
Closed 2 years ago.
I have an array of arrays which I have planted in the DOM, so that I can reuse it at a later stage to transfer to the server:
[["1","aaaaaa","1"],["2","bbbbbbb","2"],["3","ccccccc","3"]]
If I would like to convert it back into a Javascript array, how would I go about doing this?
var obj = $.parseJSON('[["1","aaaaaa","1"],["2","bbbbbbb","2"],["3","ccccccc","3"]]')
Assuming jquery is ok to use because of tag.
If the browzer has the JSON object then
JSON.parse(string);
or if you have jQuery
$.parseJSON(string);
var array = JSON.parse(my_JSON)
jQuery.parseJSON()
var myArr = $.parseJSON(myJsonString);
