copied!<p>OnKeyUp will only fire once per event. pressing 'A' 'B' and 'C' will result in three calls to suggest1();</p> <p>To make sure your browser is working correctly try this</p> <pre><code> <script type="text/javascript"> function suggest1() { document.getElementById('myDiv').innerHTML = document.getElementById('dam').value; } </script> <input type="text" name="dam" id="dam" onkeyup="suggest1();"><br /> <div id="myDiv"></div> </code></pre> <p>You should see the div change for every keystroke that occurs in the input. </p> <p>There is two many unknowns for me to directly point at your actual issue. Your PHP will output nothing for a zero entry query, and will only output 1 item if you query LIKE only matches one thing. I think your problem lies elsewhere, an not with onkeyup</p> <p>T test to onkeyup on your system/browser: Try adding some debug header like <code>echo strlen($text).'<br />';</code> to your PHP file. You should see the number change with out relying on your SQL query for every key press that adds or deletes text (that includes the backspace key). </p> <p>Your code looks fine. And runs fine for me using the public HTTP GET echo service at <a href="http://ivanzuzak.info/urlecho/" rel="nofollow">http://ivanzuzak.info/urlecho/</a></p> <p>Swapping out your PHP for the echo service works fine (with a bit of a typing delay)</p> <pre><code><script type="text/javascript"> function suggest1() { var dam_text = document.getElementById('dam').value; if (window.XMLHttpRequest) { xmlhttp = new XMLHttpRequest(); } else { xmlhttp = new ActiveXObject('MicrosoftXMLHTTP'); } xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState == 4 && xmlhttp.status == 200) { document.getElementById('myDiv').innerHTML = xmlhttp.responseText; } } var target = 'http://urlecho.appspot.com/echo?body=' + dam_text; xmlhttp.open('GET', target, true); xmlhttp.send(); } </script> <input type="text" name="dam" id="dam" onkeyup="suggest1();"><br /> <div id="myDiv"></div> </code></pre>

Querying!
