zszucs Posted October 31, 2008 Share Posted October 31, 2008 so i'm using prototype to do an autopopulate. select from a drop list and then a textbox is supposed to get filled. it works fine if it's going into a div but it doesn't work for a text box for some reason. the code is a little flaky but it does work for a div file 1 <html> <head> <title>Changing textbox value based on dropdown list using Ajax and PHP</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <script src="ajax.js"></script> <script src="prototype.js"></script> <script> function sendRequest() { new Ajax.Request("ajax.php", { method: 'post', postBody: 'id='+ $F('id'), onComplete: showResponse }); } function showResponse(req){ $('fadeBlock').innerHTML= req.responseText; //document.form1.cur_code.value = 'asdfad'; document.form1.cur_code.value = eval(req.responseText); //document.getElementById('cur_code').value=req.responseText; //$F('cur_code').value = 'asdf'; } </script> </head> <body style="font: 12px Verdana, Arial, Helvetica, sans-serif;"> <div id="fadeBlock"></div> <?php $sql = "SELECT * FROM product WHERE productid =11749"; $result = mysql_query($sql); ?> <form style="text-align:center" method="post" action="" name="form1" id="form1"> <p style="color:#000099 ">When you change the dropdown list, the respective currency code of the country will be displayed in the textbox which is fetched from PHP using Ajax. </p> <p>Country : <select name="id" onChange="sendRequest()" id="id"> <option value="">Select Country</option> <?php while($row = mysql_fetch_array($result)) { echo "<option value=\"$row[productid]\">$row[prodname]</option>\n"; } ?> </select><br/><br/> Currency : <input type="text" name="cur_code" id="cur_code" ></p> </form> </body> </html> ajax file getting called <?php include_once('functions.php'); $sql = "SELECT * FROM product WHERE id =11749"; $result = mysql_query($sql); $row = mysql_fetch_array($result); echo $row[productid]; ?> insights are appreciated Quote Link to comment Share on other sites More sharing options...

zszucs Posted October 31, 2008 Author Share Posted October 31, 2008 my bad document.form1.cur_code.value = req.responseText; actually works in a way. there was a large amount of space and then code and then the actual response that i wanted. with the large amount of space, i just assumed there was no output here's what was outputted in the text box <!-- //javascript functions, then php functions --><script>function preparehtml(whichdiv){//alert("preparing");//alert("preparing" + whichdiv);document.all("htmlfromdiv").value=document.all(whichdiv).innerHTML;document.all("prepared").value=whichdiv;}function preparetextarea(whichdiv){//alert("preparing");alert("preparing" + whichdiv);document.all("htmlfromdiv").value=document.all(whichdiv).value;document.all("prepared").value=whichdiv;}</script><SCRIPT LANGUAGE='JAVASCRIPT' TYPE='TEXT/JAVASCRIPT'> <!--/**************************************************** AUTHOR: WWW.CGISCRIPT.NET, LLC URL: http://www.cgiscript.net Use the code for FREE but leave this message intact.
