VBScript rollover. Image swap

Windows : Internet Explorer 4.0+.

VBScript rollover, using image swap. Two examples: several ways of applying VBScript in a web page.

VBScript rollover

Example 1

VBScript rollover. Image swap

HTML / XHTML. Code:

<a href="#" onmouseover="onMouse_over()" onmouseout="onMouse_out()"><img src="out.gif" id="rollover" alt="" /></a>

VBScript. Code (<script> tag including):

<script type="text/vbscript">

Sub onMouse_over()

rollover.src='over.gif'

End Sub

Sub onMouse_out()

rollover.src='out.gif'

End Sub

</script>

Note: an external VBScript script file may also be used. The code itself is the same (without <script> tag pair, surely). The file is linked to page very much like a JavaScript file would be:

<script type="text/vbscript" src="vbscript.vbs"></script>

VBScript rollover

Example 2

VBScript rollover. Image swap

HTML / XHTML. Code:

<a href="#"><img src="out.gif" id="rollover2" alt="" /></a>

VBScript. Code (<script> tag including):

<script type="text/vbscript" event="OnMouseOver" for="rollover2">

rollover.src='over.gif'

</script>

<script type="text/vbscript" event="OnMouseOut" for="rollover2">

rollover.src='out.gif'

</script>

JavaScript form submit

 

Submitting a form using JavaScript. A dropdown list (form + select + multiple options) is processed without any submit button. Example: --- Select a page --- Linux Windows DOS HTML / XHTML. Code: <form action="action.php" method="post"> <select name="page" required="required" onchange="this.form.submit()"> <option value="" selected="selected" disabled="disabled"> --- Select a page --- </option> <option value="http://www.kompx.com/en/os/linux-1.htm">Linux</option> <option value="http://www.kompx.com/en/os/windows-1.htm">Windows</option> <option value="http://www.kompx.com/en/os/dos-1.htm">DOS</option> </select> <noscript><input type="submit" value="Submit" /></noscript> </form> When an option has been chosen from the dropdown list, the form's state is changed. So the onchange event occurs and JavaScript code in onchange is executed: the process of the form submission in started by the script, not by clicking submit button which is absent. Some server-side script [ 3 ] is meant then to handle the form action. The script is supposed to get what the form sends and have it processed. A PHP script in action.php is used in the example: <?php if (isset($_POST["page"])) {     header("Location: $_POST[page]");     exit; } else {     echo "No options selected"; } $_POST is an array of variables passed to the current script via the HTTP POST method. So $_POST[page] contains the content of the value attribute in a select option. That is, a URL. It is passed from form to PHP script and the script redirects browser to the URL / page selected. HTML code of <noscript><input type="submit" value="Submit" /></noscript> is present in the form as a fallback in case JavaScript happens to be turned off. Then there is a submit button to appear and the form is usable anyway. [ 1 ] As well as Netscape 3.04+, Mozilla 0.6+. [ 2 ] As well as Netscape 3.04+, Mozilla 0.6+. [ 3 ] If a CMS is used, form action may be handled by some of its inbuilt means.

It may happen to be impossible either to install Netscape 3 or to run it under Windows 7 (32-bit). Try installing Netscape 3 as Administrator then. When installed in the proper way, Netscape 3 can run under Windows 7 (32-bit) quite well.
