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.

• So what exactly should be put/appended in/to which element? – Felix Kling Commented Mar 31, 2010 at 19:18
• Just curious, what did you search for that you didn't find any documentation? I searched on Google for both "javascript split" and "jquery split" and the first result in both cases was the location I linked to. – Charles Boyung Commented Mar 31, 2010 at 19:23
• And I am sorry but I cannot see how your code example is related to your split() problem. Give us more information :) – Felix Kling Commented Mar 31, 2010 at 19:26
• I was mistakenly thinking it was a jQuery solution when in fact it's actually a javascript thing. I also saw that documentation but dismissed it too quickly – Matt Commented Mar 31, 2010 at 19:30
• You need to remember that jQuery IS javascript - unless you are doing something with selectors (and a few other things that start with $.) you are just doing javascript, not jQuery. – Charles Boyung Commented Mar 31, 2010 at 19:35

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];

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.
