How to pull out the text written between symbols for each line from textarea?

How to pull out the text written between (any) symbols for each line from textarea using javascript.
I was thinking to use split() but didn't use it before enough. It needs to be specific enought to create array.

Example of textarea:
Mike Smith June 22 (happy)
Liza Gray May 01 (sad)
Peter Dec (lucky)

Result:
Array (happy,sad,lucky)

It's easier for me to do it excel but I need it to be done with javascript.
Hope you have a simple solution, Thanks.

Here's an example from javascript console:
> a='Mike Smith June 22 (happy)'
< "Mike Smith June 22 (happy)"
> a.substr(a.indexOf('(')+1).replace(')','')
< "happy"

Open in new window

Does this work for you?

console log it, or push to a new array. 'group' is the found element

var txt = "Mike Smith June 22 (happy) Liza Gray May 01 (sad) Peter Dec (lucky)";
txt.replace(/\(([^)]+)\)/g, function(m, group) { 
    console.log(group)
})

Open in new window


outputs:
 happy
 sad
 lucky

Using split performs marginally better, but looks uglier. Not sure it's worth the perf boost. depends how many operations you plan on doing.

var newTxt = txt.split('(');
for (var i = 1; i < newTxt.length; i++) {
        console.log(newTxt[i].split(')')[0]);
}

Open in new window


here's a perf test:

Hi,
the easiest one would be the usage of a regular expression:
/\((.*?)\)/g

Open in new window


You can test it here:

Just enter the above regex, set the global flag (the g at the end) and add your sample content - voila.

Rainer,

Simply setting the global flag you will end up with the parenthesis included in the results. see jsfiddle: http://jsfiddle.net/em1mq9b5/

You need the call back function to extract the group (ie, no parenthesis). See above solution:

or any other solution that loops over the resulting arrays:
