    <p>I have a drop down from which user can select option like "old","new". According to the selected option i am querying data from xml and displaying it in table.</p> <p>Html</p> <pre><code>&lt;body&gt; &lt;table id="NovelList" class="NovelList" border="1"&gt; &lt;tr&gt; &lt;th&gt;Novel Title&lt;/th&gt; &lt;th&gt;Author&lt;/th&gt; &lt;th&gt;Publishing Year&lt;/th&gt; &lt;th&gt;Price&lt;/th&gt; &lt;th&gt;Purchase&lt;/th&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/body&gt; </code></pre> <p>and for adding data to table on option select i am doing this:-</p> <pre><code>var nodes = xmlDoc.evaluate(pathExpr, xmlDoc, nsResolver, XPathResult.ANY_TYPE, null); var result = nodes.iterateNext(); while (result) { var b= []; var d=result.childNodes; for(var i=0;i&lt;d.length;i++){ if(d[i].nodeType == 1){ b.push(d[i]); } } for(var p=0;p&lt;b.length;p++){ var n = b[p]; if (n.localName== "title"){var t = n.childNodes[0].nodeValue;} if (n.localName== "author"){var a = n.childNodes[0].nodeValue;} if (n.localName== "year"){var y = n.childNodes[0].nodeValue;} if (n.localName== "price"){var pr = n.childNodes[0].nodeValue;} if (n.localName== "code"){var c = n.childNodes[0].nodeValue;} } $('.NovelList tr:last').after( '&lt;tr&gt;&lt;td class="value"&gt;'+ t + '&lt;/td&gt;&lt;td class="value"&gt;'+ a + '&lt;/td&gt;&lt;td class="value"&gt;' + y + '&lt;/td&gt;&lt;td class="value"&gt;' + pr + '&lt;/td&gt;&lt;td class="chk"&gt;&lt;input type="checkbox" name="chkbox" value='+'"'+c+'"'+'&gt;&lt;/td&gt;&lt;/tr&gt;'); result = nodes.iterateNext(); } } </code></pre> <p>but as i am using ".after", every time i select an option it is getting appended to the already displayed table.</p> <p>I want to replace the table rows whenever an option is selected.</p>

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.
