Question

I found another similar question about this with a solution but it didn’t work for me. I am new to jquery so thanks in advance for helping me solve my noobie question.

I am trying to use a variable for the class name. So that I can loop through the right fields based on this variable. My variable returns .reqfields4 but I get this error Error: Syntax error, unrecognized expression: ", if I enter the value manually, it works.

How can I achieve this? Thanks.

var reqsection='\".reqfields4\"';

$(".reqfields4").each ( function() { 
//$(reqsection).each ( function() {               
          if(( $(this).val())==''){
               some code...
               }
          else{
               some code...
              }
            });

Just change var reqsection='\".reqfields4\"'; to var reqsection='.reqfields4'; – you don’t need the inner string quotes.
