Hi.  

Please can someone show me the correct regex for ensuring input has ONLY the following list of chars, in any order:

0123456789-+()

Any number of whitespace is allowed.

My test code attached.

TIA, TheFoot


function(v_val){
	return /^[0-9-+]$/.test(v_val);
}

if you want to allow whitespace :

function(v_val){
	return !/[^\d\s-+()]/.test(v_val);
}
