Class to Input Field

Is there a way to add a class to the actual input field rather than just the containing div? I'm trying to get the Repeater Area to work, but all new fields completely ignore the original containing class and the javascript I've written toward that. I want each field to be able to have its own class.

Hi itpates,
​
Did you try the "Extra attributes" in the Advanced area of the field settings:

class:my_field_class

You may need to use {var:area_name.key}
​

Excellent. I can see the class applied to the additional fields via the Inspector. Now...how do I get javascript to actually recognize the added fields? I am using the following to test:
​

$(".allownumericwithdecimal").on("keyup", function(){
    alert( "You typed something!!!" );
});

The original field works perfectly. Additional fields, however, totally ignore that, even though I can see class=allownumericwithdecimal in the input field. This {var:area+name.key} - does that have something to do with this functionality? If so where do I use it, and what do I replace "area_name" with?

Hi itpates,

You will need to edit your code:

$("body").on("keyup", ".field_class", function(){
alert( "You typed something!!!" );
});

Best regards
