nor accessible because the method getElementById returns only a single HTML element instance. Unlike the getElementsByTagName method, the returned element is not guaranteed to be a certain type other than having the parameter identifier equal to the id attribute. As a result, the object model referenced after the getElementById method may or may not apply to the found element. In the case of the property innerHTML, that is not a problem because virtually all visible elements have the innerHTML property. What could be more problematic is if the identifier assumed the retrieved element were a table when in fact the element is a table cell. At that point, the object model referencing would result in an exception. When writing JavaScript code that dynamically retrieves an HTML element(s), it is a good idea to test the found element before manipulating it. As a rule of thumb, when using getElementsByTag, you know what the HTML elements are but do not know where they are or what they represent. When using getElementById, you know what the found HTML element represents and where it is, but do not know the type and hence the object hierarchy.

The property innerHTML is special in that it seems simple to use but can have devastating consequences. To illustrate the problem, consider the following HTML code: <html> <head> <title>Document Chunk HTML</title> <script language="JavaScript" type="text/javascript"> E B V N function GoodReplace() { document.getElementById("mycell").innerHTML = "hello"; } function BadReplace() { document.getElementById("mytable").innerHTML = "hello"; } function TestTable() { window.alert(document.getElementsByTagName( "table")[ 0].rows[ 0].cells[ 0].innerHTML); } </script> </head> <body> <button onclick="GoodReplace()">GoodReplace</button> <button onclick="BadReplace()">BadReplace</button> <button onclick="TestTable()">TestTable</button> <table id="mytable" border="1"> <tr id="myrow"><td id="mycell">Nothing</td><td>Second cell</td></tr> </table> </body> </html>

In this example, there are three buttons (GoodReplace, BadReplace, and TestTable), and the HTML elements table, table row, and row cell have added identifiers. The GoodReplace button will perform a legal HTML injection. The BadReplace button will perform an illegal HTML injection. And the TestTable button is used to test the validity of an object model. The TestTable button is used as a way of verifying the result of the HTML injection performed by either GoodReplace or BadReplace. Downloading the HTML page and presenting it in the browser results in something similar to Figure 3-5.

Figure 3-5. Initial generation of the HTML page To check that the HTML page is in a valid state, the button TestTable is clicked. Clicking the button calls the function TestTable, which tests whether the content within a table cell exists by outputting the content in a dialog box. The generated output appears similar to Figure 3-6. The dialog box in Figure 3-6 confirms that the table cell contains the value Nothing. This means our HTML page is in a stable state. If the GoodReplace button is clicked, the function GoodReplace is called, which changes the table cell contents from Nothing to Hello. To verify that the HTML page is still valid, the TestTable button is clicked. If the HTML page is valid, a dialog with the text Hello should appear, and it does, as is illustrated in Figure 3-7.

Figure 3-7. Modified contents of the cell For interest, let s add some complications by clicking the button BadReplace. Clicking BadReplace calls the function BadReplace, and that assigns the property innerHTML of the HTML table with other text. This means that the HTML content <table><tr><td>...</table> is changed to <table>Nothing</table>. The changed HTML is not legal and is displayed as shown in Figure 3-8.
