How to use split?

I have a string likes below
a_b_c_d
I hope to decode it to an array t as
t[0]->a
t[1]->b
t[2]->c
t[3]->d
Just wonder if there ia function of javascript can parse the string directly.
var string = "a_b_c_d";
var t = string.split('_');
DEMO FIDDLE
Just split the string
var t = "a_b_c_d".split("_");

I have a string like this
var assignments= "NAME1,NAME2,NAME3,NAME4,NAME5,NAME6"
how do i print only first three strings like this "NAME1,NAME2,NAME3" in JavaScript
You can do this way
let string= "NAME1,NAME2,NAME3,NAME4,NAME5,NAME6".split(',')
let output = string.splice(',',3).join(',')
console.log(output)
Using standard Array functions you can do what you want. The code below shows the various stages, though you can write it more concisely as one line if you like.
var assignments= "NAME1,NAME2,NAME3,NAME4,NAME5,NAME6"
var splitAssignements = assignments.split(",")
var firstThreeArray = splitAssignements.slice(0,3)
var firstThreeString = firstThreeArray.join(",")
console.log(firstThreeString)

I have a string like below.
sections = "12A,13B,14C"
But I need [12A, 13B, 14C] for future use. How to create array from above string?
You have to use split method for that to split your string data into array values, have a look to updated code
var sections = "12A,13B,14C";
sections = sections.split(',');
console.log(sections);
Hope this will help! Just use split method of JS.
sections = "12A,13B,14C"
let array = sections.split(',');
console.log(array)

how to convert the following string to map so that i can access the values
data.message ="{"id":"60653","key":"project1","self":"http://127.0.0.1:321/rest/api/2/issue/project1"}"
if your string is a valid JSON just use the JSON.parse function:
var str = '{"id":"60653","key":"project1","self":"http://127.0.0.1:321/rest/api/2/issue/project1"}'
var mydata = JSON.parse(str);
Use JSON.parse
Here's the corresponding MDN documentation:

I have a string that always contains 8 variable values that are separated with a hypen (-) like in the following example:
5-2-2-2-2-2-2-1
What is the best way to split this into 8 separate values so that I can use each of them in a variable if the values can be either an integer or the value 'n/a' ?
Many thanks for any help with this, Tim.
var str = '5-2-2-2-2-2-2-1';
var parts = str.split('-');
for (var i=0;i<parts.length;i++){
console.log(parts[i]);
}

How can I get query string values in JavaScript?

Given the following string/query string:
ajax/hovercard/hovercard.php?id=100000472545907&extragetparams=%7B%22hc_location%22%3A%22stream%22%7D
What is the best way to extract the id?
Try this:
yoururl.match(/id=(.*)&/)[1]
Fiddle
params = location.search.substring(location.search.indexOf('id')).split('&')[0]
id = params.substr(3)
If it is always shipped in this exact order - then
url.match(/\d+/)
otherwise
url.match(/id=(\d+)/)
