I'm trying to develop a website with a left frame div and a main div, whereby the content of the main div changes depending on what you click on in the frame div. I'm trying to achieve this with onclick, which calls a function setValue(i) and sets the global variable value. From my main div I call a function content() which has if...else statements to display different content depending on the value variable. But for some reason, even though I'm declaring value outside of any functions, when setValue assigns a number to value, it doesn't seem to carry into the function content(). Can anyone help me figure out what I'm doing wrong? I've looked it over and over, and researched online, and can't figure it out. I've just started learning Javascript, so it's probably something really simple. The code is below:
In the <head> section: - <script type="text/javascript">
-
var value;
-
function setValue(i)
-
{
-
value=i;
-
}
-
function content()
-
{
-
if (value==1)
-
{
-
document.write("<a href='cheungfai.html'>");
-
document.write("<img src='images/IMG_0171s.jpg'/>");
-
document.write("<p class='p3'>");
-
document.write("Travel and Nature Portfolio");
-
document.write("</p></a>");
-
}
-
}
-
</script>
-
In the <body> section:
[HTML]<div class="leftframe">
<p class="p2" onclick="setValue(1)" />

<div class="maincontent">
<p><script type="text/javascript">

</script></p>
</div>[/HTML]
