<p>Hei, I'm trying to fill a textfield declared in a jsp file with some text after calling a servlet using Ajax. The xmlhttp.responseText contains the text returned by the servlet, but the input with the message id is not filled with that text and I don't know why. Any suggestions? The code used is below. </p> <pre><code>function ajaxFunction() { if(xmlhttp) { var txtname = document.getElementById("txtname"); xmlhttp.open("POST","getname",true); //getname will be the servlet name xmlhttp.onreadystatechange = handleServerResponse; xmlhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xmlhttp.send("txtname=" + txtname.value); //Posting txtname to Servlet } } function handleServerResponse() { //alert(xmlhttp.readyState);//ok if (xmlhttp.readyState == 4) { alert(xmlhttp.status); if(xmlhttp.status == 200) { alert(xmlhttp.responseText); // this is ok document.getElementById("message").innerHTML=xmlhttp.responseText; // doesn't work //document.myForm.message.innerHTML=xmlhttp.responseText; //neither } else { alert("Error during AJAX call. Please try again"); } } } </script> <body> <form name="myForm" method="POST" action="/ajjax/getname"> <table> <tr> <td>Enter Name</td> <td><input type="text" name="txtname" id="txtname" /></td> </tr> <tr> <td colspan="2"><input type="button" value="Submit" onclick="ajaxFunction();" /></td> </tr> </table> <input type="text" name="message" id="message" /> </form> </body> </head> </html> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
