jQuery : how to get array value from array key

Question

Say I have an array :

var courseArray = array('0.15' => '10 Unités', '0.20' => '20 Unités', '0.30' => '30 Unités');

Now I want to to corresponding value from this array if I know the key.

Something like will do ?

var courseArray = array('0.15' => '10 Unités', '0.20' => '20 Unités', '0.30' => '30 Unités');
var courseKey = $( "#amount" ).val();
var courseValue = courseArray[courseKey];

Thanks for any help.

var courseArray = {'0.15':'10 Unités', '0.20' :'20 Unités', '0.30':'30 Unités'}; — Pranav C Balan

use below code .

Array you have created is not valid;

you need to create JSON Object to get data base on key . (LINK)

DEMO

var courseArray = {'0.15':'10 Unités', '0.20':'20 Unités', '0.30':'30 Unités'};
alert(courseArray['0.15']);
