没有提交表单的Mysql num行

Question

I have a jquery php mysql query, which works fine, but before my form being submitted, I would like to tell my visitors how many results will they receive. For example: Show results (5).

Could you tell me an easy way of doing that please?

I would really appreciate it.

edit: my ajax looks like the following:

<script language="javascript" type="text/javascript">
<!-- 
//Browser Support Code
function ajaxFunction(){
 var ajaxRequest;  // The variable that makes Ajax possible!

 try{
   // Opera 8.0+, Firefox, Safari
   ajaxRequest = new XMLHttpRequest();
 }catch (e){
   // Internet Explorer Browsers
   try{
      ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
   }catch (e) {
      try{
         ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
      }catch (e){
         // Something went wrong
         alert("Your browser broke!");
         return false;
      }
   }
 }
 // Create a function that will receive data 
 // sent from the server and will update
 // div section in the same page.
 ajaxRequest.onreadystatechange = function(){
   if(ajaxRequest.readyState == 4){
      var ajaxDisplay = document.getElementById('ajaxDiv');
      ajaxDisplay.innerHTML = ajaxRequest.responseText;
   }
 }
 // Now get the value from user and pass it to
 // server script.
 var bedno = document.getElementById('bedno').value;
 var district = document.getElementById('district').value;
 var loc = document.getElementById('location').value;
 var queryString = "?bedno=" + bedno ;
 queryString +=  "&district=" + district + "&location=" + loc;
 ajaxRequest.open("GET", "ajax-example.php" + 
                              queryString, true);
 ajaxRequest.send(null); 
}
//-->
</script>

Answer 1

Your AJAX is right.
In your ajax-example.php file fetch the result using your parameters.
And echo the result.
example

 $st = mysqli_query($link, "your query");
 $result = mysqli_num_rows($st);
 echo $result;
