How to use split?

How to use split?

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($(‘

‘).text($(‘[id$=txtEntry2]’).val()));

I figure “split” is the way to go, but there is very little documentation that I can find.

Solutions/Answers:

Solution 1:

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])));

Solution 2:

If it is the basic JavaScript split function, look at documentation, JavaScript split() Method (W3Schools).

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];

Solution 3:

Look in JavaScript split() Method

Usage:

"something -- something_else".split(" -- ") 

Solution 4:

    var str;
    var sid = new Array();
    str = "your_string";
    sid = (str.split("_"));

Output:

    sid[0]="your";
    sid[1]="string";
