    <p>The task at hand is to dynamically create an HTML table from variable values passed to a new page through its URL. The HTML table needs four columns: <strong>Product Name</strong>, <strong>Item Number</strong>, <strong>Price</strong>, and <strong>Quantity</strong>.</p> <p>I am using the JavaScript DOM to accomplish this task. However, I cannot get my code to work properly because I think I am misusing the tBodies[0].appendChild(tr) method. I can only get the last column in my table to display. The first 3 columns do not display. Any ideas where I've gone wrong?</p> <pre><code>&lt;FORM NAME=order ACTION=submit.php METHOD=GET&gt; &lt;TABLE ID=gradient-style SUMMARY=EuroClassic Dynamic Ordering&gt; &lt;THEAD&gt; &lt;TR&gt; &lt;TH scope=col&gt;Product&lt;/th&gt; &lt;TH scope=col&gt;Item #&lt;/th&gt; &lt;TH scope=col&gt;Price&lt;/th&gt; &lt;TH scope=col&gt;Quantity&lt;/th&gt; &lt;/TR&gt; &lt;/THEAD&gt; &lt;TBODY&gt; &lt;SCRIPT language=javascript&gt; var vars = [], hash; var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&amp;'); var i = 0; while(i &lt; hashes.length) { hash = hashes[i].split('='); vars.push(hash[0]); vars[hash[0]] = hash[1]; // hasQuantity Array created to test if the Quantity Variable // is zero or not...is product ordered? var hasQuantity = new Array(); hasQuantity = hashes[i+4].split('='); // hasQuantity != 0 indicates product has been ordered... if(hasQuantity[1] != 0) { var nameProduct = hashes[i].split('='); var tr = document.createElement('tr'); var td = document.createElement('td'); var input = document.createElement('input'); input.type = "text"; input.size = 40; input.name = nameProduct[0]; nameProduct[1] = nameProduct[1].replace(/%/g,''); nameProduct[1] = nameProduct[1].replace(/2C/g,''); nameProduct[1] = nameProduct[1].replace(/2F/g,''); nameProduct[1] = nameProduct[1].replace(/28/g,''); nameProduct[1] = nameProduct[1].replace(/29/g,''); nameProduct[1] = nameProduct[1].replace(/\+/g," "); input.value = nameProduct[1]; input.readOnly = true; td.appendChild(input); tr.appendChild(td); document.getElementById('gradient-style').tBodies[0].appendChild(tr); i++; var nameItem = hashes[i].split('='); input.type = "text"; input.size = 6; input.name = nameItem[0]; input.value = nameItem[1]; input.readOnly = true; td.appendChild(input); tr.appendChild(td); document.getElementById('gradient-style').tBodies[0].appendChild(tr); i = i+4; var namePrice = hashes[i].split('='); input.type = "text"; input.size = 6; input.name = namePrice[0]; input.value = namePrice[1]; input.readOnly = true; td.appendChild(input); tr.appendChild(td); document.getElementById('gradient-style').tBodies[0].appendChild(tr); i++; var nameQuantity = hashes[i].split('='); input.type = "text"; input.size = 6; input.name = nameQuantity[0]; input.value = nameQuantity[1]; input.readOnly = true; td.appendChild(input); tr.appendChild(td); document.getElementById('gradient-style').tBodies[0].appendChild(tr); i++; } //If Quantity Ordered is Zero, Proceed to next set of variables else { i=i+7; } } &lt;/SCRIPT&gt; &lt;/TBODY&gt; &lt;/TABLE&gt; &lt;/FORM&gt; </code></pre>

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.
