    <p>I already have add/delete rows dynamically in Javascript, there is no problem in adding rows, only having a problem with deleting rows. For now, what I have made is when I want to delete a row <strong>it always deletes the last one</strong>, so I think <strong><code>I want if it only can be deleted the selected row</code></strong>, and I don't know how to modify the script to what I wanted be.</p> <p>Here is the script:</p> <pre><code>var i=0; function addRow() { i++; m.r.value = i; var tbl = document.getElementById('table'); var lastRow = tbl.rows.length; var iteration = lastRow - 1; var row = tbl.insertRow(lastRow); var cellLeft = row.insertCell(0); var textNode = document.createTextNode(iteration); cellLeft.appendChild(textNode); var cellRightSel1 = row.insertCell(1); var sel = document.createElement('select'); sel.name = 'name' + iteration; sel.setAttribute("onchange", "choosec(this);"); var item = new Option("",""); sel.options[sel.length] = item; &lt;? while($data = mysql_fetch_array($result)){ ?&gt; var item = new Option("&lt;?=$data["Name"];?&gt;","&lt;?=$data["ID"];?&gt;"); sel.options[sel.length] = item; &lt;? } ?&gt; cellRightSel1.appendChild(sel); var cellRightSel2 = row.insertCell(2); var sel = document.createElement('select'); sel.name = 'class' + iteration; sel.setAttribute("onchange", "choosepoint(this);"); var item = new Option ("",""); sel.options[sel.length] = item; &lt;? while($data = mysql_fetch_array($result_sub)){ ?&gt; var item = new Option("&lt;?=$data["Class"];?&gt;","&lt;?=$data["ID"];?&gt;"); sel.options[sel.length] = item; &lt;? } ?&gt; cellRightSel2.appendChild(sel); var cellRight = row.insertCell(3); var div = document.createElement('div'); div.id = 'point' + iteration; cellRight.appendChild(div); } function removeRow(){ var tbl = document.getElementById('table'); var lastRow = tbl.rows.length; var rem = lastRow - 1; if (lastRow &gt; 2) tbl.deleteRow(rem); } </code></pre> <p>Help is appreciated, thanks.</p> <p><strong>My solved problems:</strong></p> <pre><code>function removeRow(t){ var i = t.parentNode.parentNode.rowIndex; var tbl = document.getElementById('table'); var lastRow = tbl.rows.length; var iteration = lastRow - 1; tbl.deleteRow(i); } </code></pre>

    1. COA global var named `i`? Inline event handler? Have you considered using jQuery? (Actually, before people like Raynos complain about suggesting jQuery, you can also improve that without jQuery - but why write more code than encessary)

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.
