get search results then populate page without refresh

I am not realy sure where to start. I have a page setup to search for members in my admin panel. I am trying to find a way to get search results without refreshing the page when clicking a button. I already have a file that searches the db which is a seperate php file. The page the search box is on is also a php file. I have spent days googling and reading posts on here with little success. All i want is a button that when clicked will search the db for the member name in the search box then populate a list on the same page without refreshing the page. any tips would be much appreciated. this is my searchbox code below.

        <div class="search-box">
        <input type="text" autocomplete="off" class="inputboox1" tabindex="1" placeholder="Search Member..." />
        <div class="result" style='overflow:auto; width:190px;max-height:100px;'></div>
    </div>

You need to use ajax for this, try something like that with jQuery:

var searchValue = $('#idOfSearchField').val();
$.ajax({
    url: 'search.php',
    data: {
      text: searchValue
    },
    cache: false,
    success: function(data) {
        $('.result').html(data);
    }
});

You can even use "keydown" events to send queries as the user types

You should use ajax.

  1. Create your HTML form
  2. Add a click event on your submit button
  3. Call your backend endpoint from javascript
  4. Display the response

Here is an example from w3schools:

HTML:

<html>
  <head>
  <script>
    function showResult(str) {
      if (str.length==0) { 
        document.getElementById("livesearch").innerHTML="";
        document.getElementById("livesearch").style.border="0px";
        return;
      }
      if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
      } else {  // code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
      }
      xmlhttp.onreadystatechange=function() {
        if (this.readyState==4 && this.status==200) {
          document.getElementById("livesearch").innerHTML=this.responseText;
          document.getElementById("livesearch").style.border="1px solid #A5ACB2";
        }
      }
      xmlhttp.open("GET","livesearch.php?q="+str,true);
      xmlhttp.send();
    }
  </script>
  </head>
  <body>

    <form>
      <input type="text" size="30" onkeyup="showResult(this.value)">
      <div id="livesearch"></div>
    </form>

  </body>
</html>

PHP:

<?php
$xmlDoc=new DOMDocument();
$xmlDoc->load("links.xml");

$x=$xmlDoc->getElementsByTagName('link');

//get the q parameter from URL
$q=$_GET["q"];

//lookup all links from the xml file if length of q>0
if (strlen($q)>0) {
  $hint="";
  for($i=0; $i<($x->length); $i++) {
    $y=$x->item($i)->getElementsByTagName('title');
    $z=$x->item($i)->getElementsByTagName('url');
    if ($y->item(0)->nodeType==1) {
      //find a link matching the search text
      if (stristr($y->item(0)->childNodes->item(0)->nodeValue,$q)) {
        if ($hint=="") {
          $hint="<a href='" . 
          $z->item(0)->childNodes->item(0)->nodeValue . 
          "' target='_blank'>" . 
          $y->item(0)->childNodes->item(0)->nodeValue . "</a>";
        } else {
          $hint=$hint . "<br /><a href='" . 
          $z->item(0)->childNodes->item(0)->nodeValue . 
          "' target='_blank'>" . 
          $y->item(0)->childNodes->item(0)->nodeValue . "</a>";
        }
      }
    }
  }
}

// Set output to "no suggestion" if no hint was found
// or to the correct values
if ($hint=="") {
  $response="no suggestion";
} else {
  $response=$hint;
}

//output the response
echo $response;
?>
