I need to break apart a string that always looks like this:
something — something_else.
I need to put “something_else” in another input field. Currently, this string example is being added to an HTML table row on the fly like this:
tRow.append($('<td>').text($('[id$=txtEntry2]').val()));
I figure “split” is the way to go, but there is very little documentation that I can find.

Documentation can be found e.g. at MDN. Note that .split() is not a jQuery method, but a native string method.
If you use .split() on a string, then you get an array back with the substrings:
var str = 'something -- something_else';
var substr = str.split(' -- ');
// substr[0] contains "something"
// substr[1] contains "something_else"
If this value is in some field you could also do:
tRow.append($('<td>').text($('[id$=txtEntry2]').val().split(' -- ')[0])));
If it is the basic JavaScript split function, look at documentation, JavaScript split() Method.
Basically, you just do this:
var array = myString.split(' -- ')
Then your two values are stored in the array – you can get the values like this:
var firstValue = array[0];
var secondValue = array[1];
0
Look in JavaScript split() Method
- Mozilla Developer Network
- W3Schools
Usage:
"something -- something_else".split(" -- ")
According to MDN, the
split()method divides a String into an
ordered set of substrings, puts these substrings into an array, and
returns the array.
🔸 Example
var str = 'Hello my friend'
var split1 = str.split(' ') // ["Hello", "my", "friend"]
var split2 = str.split('') // ["H", "e", "l", "l", "o", " ", "m", "y", " ", "f", "r", "i", "e", "n", "d"]
🔹 In your case
var str = 'something -- something_else'
var splitArr = str.split(' -- ') // ["something", "something_else"]
console.log(splitArr[0]) // something
console.log(splitArr[1]) // something_else
