Jquery Label selector with variable appended not working

Question

label selector with variable appended

 var altRoute= getAlternateRoute(route);
  $("label[for='b-'+altRoute+'-0-option']").addClass("muted");

This code snippet is not working? what am doing wrong here?

Answer 1

You have misplaced quotes. Use like this,

var altRoute = getAlternateRoute(route);
$("label[for='b-" + altRoute + "-0-option']").addClass("muted");
