Body
You're passing a string, not a variable, use: <pre><code>onclick="myFunction(data)" </code></pre> A string must be quoted, a variable (a reference, in this case, to a string) must not (otherwise it'll be assessed as a literal string). Incidentally, JavaScript doesn't require you to explicitly create a string before assigning a value to it, you could use just: <pre><code>var data = 'This is what I want to show.'; </code></pre> And while using <code>innerHTML</code> works, if all you're doing is updating text content (and there are no nested nodes to be considered) you could simply use: <pre><code>function myFunction(text) { // the var declaration prevents the variable becoming global var elem = document.getElementById('replace'); elem.appendChild(document.createTextNode(text)); } </code></pre> And to make it more generally-useful, avoid hard-coding the <code>id</code> of the element to change within the function, instead pass it to the function: <pre><code>function myFunction(text, elem) { // testing if the element is a node, if not assume it's a string of the id: var elem = elem.nodeType === 1 ? elem : document.getElementById('replace'); elem.appendChild(document.createTextNode(text)); } </code></pre> And coupling the above with: <pre><code>onclick="myFunction(data, 'replace')" </code></pre> Or: <pre><code>onclick="myFunction(data, document.getElementById('replace'))" </code></pre> I'd also, strongly, advise not using in-line/obtrusive JavaScript, simply to make it easier to update the functions to be called, the arguments and the functions themselves, in one place (rather than having to navigate through the document and finding every instance in which the function is called): <pre><code>// define the function here var buttons = document.getElementsByTagName('button'), replace = document.getElementById('replace'), data = 'Text I want to show.'; for (var i = 0, len = buttons.length; i < len; i++){ buttons[i].onclick = function(){ myFunction(data, replace); }; } </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.
