kwstephenchan Posted January 7, 2009 Share Posted January 7, 2009 Hi all. I intend to have an input field in PHP program 1. Besides this input field, I have a button so that the user can search for value to be used instead of inputing. On pressing this button, another php program, say program 2 will be called. Program 2 will go to the database and list the values for selection. The user can then select and the selected value will be passed back to program 1 (without refreshing other fields in program 1) Can anyone advise how this can be done? I tried using Ajax, but it does not seem to be doing the trick, wonder what have I done wrong. Thanks Followings are the code bit: ***** javascript definition **** <script type="text/javascript"> var XMLHttpRequestObject = false; if (window.XMLHttpRequest) { XMLHttpRequestObject = new XMLHttpRequest(); } else if (window.ActiveXObject) { XMLHttpRequestObject = new ActiveXObject("Microsoft.XMLHttp"); } function getData(srcPHP, parm) { var url = srcPHP+"?parm=" + parm; if(XMLHttpRequestObject) { XMLHttpRequestObject.open("GET", url, true); XMLHttpRequestObject.onreadystatechange = function() { if (XMLHttpRequestObject.readyState == 4 && XMLHttpRequestObject.status == 200) { eval(XMLHttpRequestObject.responseText); } } XMLHttpRequestObject.send(null); } } function alerter(divID,pvalue) { alert(' back toJavaScript'); var showDiv = document.getElementById(divID); showDiv.innerHTML = pvalue; } </script> **** parts of program calling the Javascript **** <tr valign="baseline"> <div width="40%" height="20" align="right" class="lbtxt">Owner : </div> <div height="20" class="intxt"> <input name="m_ownerid" type="text" id="m_ownerid" size="4"> <font color="#ffffff"><?php $divID="m_ownerid"; $srcData="data.php"; $str="<img src='images/moredot.gif'>"; echo '<a href=javascript:getData(\''.$srcData.'\',\''.$divID.'\') >'.$str.'</a>'; ?>*</font></div> </tr> ***** code content in data.php **** <?php $parm = $_GET['parm']; $pvalue="passing value"; echo 'alerter(\''.$parm.'\',\''.$pvalue.'\')'; // echo '<a href=javascript:getData(\''.$srcData.'\',\''.$divID.'\') >'.$str.'</a>'; ?> <?php /* <html> <body> <table> <tr> <td> this is the html part </td> </tr> </table> </body> </html> */ ?> As noted, I have commented out the html part because if I leave them in, I'll get page error. As I am new to Ajax, wonder if it is true that the second PHP program cannot have HTML in it. Thanks for all the help.
