hi

i write below code for filter textfield and textarea in part of my form , that code is as follow as

(function($){
  $.fn.setReadOnly = function(readonly, opacityRo, opacityNRo) {
    if(!opacityNRo) {
            opacityNRo = 1; 
    }
    if(!opacityRo) {
            opacityRo = 0.5; 
    }
 
    if(opacityRo<=100 && opacityRo>1) {opacityRo /= 100;}
    if(opacityNRo<=100 && opacityNRo>1) {opacityNRo /= 100;}
 
   return this.filter('input:text').add('textarea')
      .attr('readonly',readonly)
      .css('opacity', readonly ? opacityRo : opacityNRo);
  } 
})(jQuery);
 

in this code i filter wraped set to textfield and add textarea how i can make list of textfield and textarea without need to add textarea later . my meaning is that writing textfield and textarea together in filter method

thanks alot for your help.
