Q160 Can you access global variables (such as MyName) from a different page than where it is held?

There are four means of passing data from one page to another:

• Using cookies
• Using the location search property
• Using frames
• Using hidden form fields - although I have not tested this out yet
• Using the location hash property - although doesn;t work on very old browsers

There are loads of articles/examples on this site that describe the first three options.

Far and away the best is the 2nd method:

<script language="JavaScript"><!--
function nextpage(href,string) {
    location.href = href + '?' + string;
}

<a href="javascript:nextpage('apage.html',MyName);">Next Page<\/a>

And then in the next page:

<script language="JavaScript"><!--
if (location.search.length > -1)
    document.write("Hello, " +  location.search.substring(1));
//--></script>

NOTE: the above technique "appears" to fail in Internet Explorer 3 and 4. If it does fail, this is because you are attempting this offline. Once you move your pages online it will work.
