jQuery inArray not working

in my validation the required fields can change. I have an array (required) of input ids which are required. If the array contains the string 'All' then all inputs are required.

I'm trying to use JQuery.inArray() to determine if required.

function getIfRequired(id){
    console.log("id: "+id);
    console.log(required);
    console.log("inarray: "+jQuery.inArray(required, 'All'));

    if (jQuery.inArray(required, 'All') > -1){ return true; }
    else if(jQuery.inArray(required, id) != -1){ return true; }
    else{ return false; }
}

But it keeps returning '-1' (not found).

here are example log outputs:

id: clientname
["clientname", "sourceid", "clientcountry","clienttown", "clienttownid", "typeoflaw"] 
inarray: -1 

id: clientname
["All"] 
inarray: -1

Why is it not working?

You call wrong jQuery.inArray. First goes the value and then the array

see http://api.jquery.com/jQuery.inArray/

write 

jQuery.inArray('All', required);

instead of 

jQuery.inArray(required, 'All');

because required not found in All

You will write as below

 console.log("inarray: "+jQuery.inArray('All', required));

You have your value and array parameters transposed, e.g.:

jQuery.inArray('All', required);
