jquery validation自加方法bigger 检验某字段值大于某数或者另一字段

jQuery.validator.addMethod("bigger", function(value, element, param){

// bind to the blur event of the target in order to revalidate whenever the target field is updated

// TODO find a way to bind the event just once, avoiding the unbind-rebind overhead

var target = $(param);

//alert(value + ':' + param + '-' + target.val());

if(target.size()==0){

target = $("input[name='" + param+"']");

}

if(target.size()==0){

//input number we compare with number directly

if(parseInt(param) == param){

return parseInt(value) >= parseInt(param);

}else{

return false ;

}

}

return parseInt(value) >= parseInt(target.val());

}
