Magento custom validation and remove forward and back slashes

var theForm = new VarienForm('theForm', true); 
Validation.add('validate-hello','You failed to enter!',
function(field_value){
if(field_value == 'hello')
{ return true; } return false; }); 

Lastly add your validation class to your input field.

 v = v.replace(/\//g, '');
v = v.replace (/\\/g,'');

Where the variable is declared already.
