Increasing value of Javascript Variables?

Question

Hello!

im processing link click events with mootools. in my html i have a links with the id of this pattern: toggle_NUMBER e.g. toggle_1 now i get the id with this peace of code

var id = $(this.get('id').replace(togglePrefix,emptyPrefix)); 

my problem starts now: i remove the prefix this way

var togglePrefix = 'toggle_', boxPrefix = 'page_', emptyPrefix = '';

so what should remain is a simple number like 1, 2 or 3. now i tried to increase this number by one

var id_new = parseInt(id)+1;

but this didnt work and i have no clue how to change it! Plz help!

Answer 1

Variable "id" is an object, because return value of $ function in mootools (and jQuery) is an object.

Try this:

var id_new = $(this).get('id').replace(togglePrefix, emptyPrefix) + 1;

Answer 2

Did you try $(this).next() before you went hacking into the ID?
