var queryString = "f_name=" + f_name + "&l_name=" + l_name + "&contact_no=" + contact_no + "&email=" + email;
$.ajax({
    type:'POST',
    url:'insert1.php',
    data:queryString,
    dataType:'json',

data key must be of object type This will work for you

var hashString = "#support_form";

$.ajax ({
   type: "POST",
   url:"index.php",
   data: {'hashString':hashString},
   success: function() {
      console.log("message sent!");
   }
});

Your JS should be this: 

var hashString = "#support_form";

$.ajax ({
   type: "POST",
   url:"index.php",
   data: {hashString: hashString},
   success: function() {
      console.log("message sent!");
   }
});

Your code would work if you used an object instead of a string. try this:

var hashString = {hashString: "#support_form"};

$.ajax ({
   type: "POST",
   url:"index.php",
   data: hashString,
   success: function() {
      console.log("message sent!");
   }
});

You have to do like this-

$.ajax ({
   type: "POST",
   url:"index.php",
   data: "hashString=value",
   success: function() {
      console.log("message sent!");
   }
});

So you can get the value as-

$theHash = $_POST['hashString'];
echo $theHase; //will print value

You need to specify the name/value for data

data: {hashString:hashString},

Use:

data: 'hashString=' + encodeURIComponent(hashString),
