validation - How to match a value to a string within "rules" using jquery validate.js (bassistance.de) -

i want check if form radio input value matches string exactly, "equalto" match string , not field input can't find if there simple way similar using "equalto".

as below want form field "foo" value match "bar" , hoping replace ????????s simple command if possible?

if not appreciate showing how can implement string match within "rules" method.

$("#this_form").validate({ rules:{             name:{                  required:true                  },              foo:{                  ????????: "bar",                  required:true                  }         } 

});

so here want form validate if value of foo "bar" , not if value "manchu".

< input type="radio" name="foo" value="bar" />

< input type="radio" name="foo" value="manchu" />

(i think reason pretty obvious, answer foo needs bar otherwise not want form submit.)

you can this:

  jquery.validator.addmethod("myfunc", function(val) {     if(val=='mystring'){       return true;     }     return false;   }, "values not match."); 

you can use method 'myfunc' use built in email function.

... foo:{      myfunc:true
