This uses regular expressions and the exec method:

var s = blabla blabla-5 amount-10 blabla direction-left;

var amount = parseInt(/amount-(d+)/.exec(s)[1], 10);

var direction = /direction-([^s]+)/.exec(s)[1];

The code will cause an error if the amount or direction is missing; if this is possible, check if the result of exec is non-null before indexing into the array that should be returned.
