    <p>Say I have an html code like this:</p> <pre><code>&lt;script&gt; // just an example function to get data from input function getNumber(form) { var userInput = new Number; // convert form values into numbers userInput = Number(form.enteredNumber.value); return userInput; } function countNumbers(form) { var lastNumber = getNumber(form); // the last number to be counted for (i = 1; i &lt;= lastNumber; i++) { //count the numbers document.write(" "+i); // put the numbers on the page if((i % 10) == 0) { document.write("&lt;br&gt;"); // insert a break 10 by 10 to create a block of numbers } } } &lt;/script&gt; &lt;form&gt; Enter a number:&lt;input type="text" name="enteredNumber"/&gt; &lt;input type="button" value="Count!" onClick="countNumbers(this.form);"/&gt; &lt;/form&gt; &lt;div id="numberBlocks"&gt;&lt;/div&gt; </code></pre> <p>So if user entered 25 the result would be close to what I want, like this:</p> <p>1 2 3 4 5 6 7 8 9 10</p> <p>11 12 13 14 15 16 17 18 19</p> <p>20 21 22 23 24 25</p> <p>But the document.write clears the entire page, and I don't want that. If I use:</p> <pre><code>document.getElementById('numberBlocks').InnerHTML = i; document.getElementById('numberBlocks').InnerHTML = '&lt;br&gt;'; </code></pre> <p>it will merely replace the contents of the element, I don't want that either. the output will be:</p> <p>nothing or a number&lt;--- since the last element will be a break tag or a number.</p> <p>How do I do this, in a way, the content of page isn't destroyed and the output result is what I want?</p> <pre><code>document.getElementById('numberBlocks').InnerHTML += i document.getElementById('numberBlocks').InnerHTML = " " + "&lt;br&gt;"; </code></pre> <p>won't work either, since they will overwrite the element instead of adding new ones.</p> <p>And these two would generate the same result as document.write</p> <pre><code>res = document.getElementById('numberBlocks'); res.innerHTML = res.innerHTML +" "+i; res = document.getElementById('numberBlocks'); res.innerHTML = res.innerHTML + "&lt;br&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.
