hi,
i would like to know how i can evaluate the current url so that either javascript :history.go(-1)'or javascript :history.go(-2) is executed. I would like for the javascript :history.go(-2) to be executed if the url is suffixed with the "#top"... like http://localhost...#top. I currently have: -
echo "<A HREF='javascript:javascript:history.go(-1)'>HOME</A><br><br>";
-
thanks in advance,
geebee

now i have: -
-
<html>
-
-
<BODY>
-
-
<SCRIPT LANGUAGE="JavaScript">
-
-
function showLoc()
-
{
-
var x = window.location;
-
-
if (x = "http://httplocalhost/checkurl.html")
-
{
-
document.write("<a href='http://www.microsoft.com'>go to microsoft</a>");
-
}
-
else
-
{
-
document.write "stay here"
-
}
-
-
var t = ['Property - Typeof - Value',
-
'window.location - ' + (typeof x) + ' - ' + x ];
-
for (var prop in x){
-
t.push(prop + ' - ' + (typeof x[prop]) + ' - ' + (x[prop] || 'n/a'));
-
}
-
alert(t.join('\n'));
-
}
-
</SCRIPT>
-
-
-
-
</html>
-
but its not doing anything...
saying "error on page" at the bottom of the window.

firstly, window.location is an object, not a string. secondly, there's a syntax error in line 18 (missing brackets) and probably the wrong operator on line 12. thirdly, javascript should be served with a type declaration in the <script> tag.
ok..
i figure it out.. here is my code... appearing at the bottom after the PHP code: -
<SCRIPT LANGUAGE="JavaScript">
-
function showLoc()
-
{
-
var x = window.location;
-
if (x == "http://localhost/checkurl.html")
-
{
-
document.write("<a href='http://www.microsoft.com'>go to microsoft</a>");
-
}
-
else
-
{
-
document.write ("stay here")
-
}
-
-
}
-
-
x=0;
-
document.self.location.reload();
-
</SCRIPT>
-
the only problem now is i cant figure out how to get the document.write results after the results of my PHP are listed. i tried <BODY ONLOAD = ...> but that only lists the document.write output from the javascript.
thanks in advance,
geebee

what PHP code?
just out of interest, do you ever enter the first statement in the if clause?
yes, i entered the first line of the IF statement. but it only works if i have the <BODY ONLOAD = showLoc()..> and then my PHP output does not display. only the document.write output from the javascript function displays. i want the PHP results to display as a result of my PHP code (not posted here because it is irrelevant i think), and then the document.write from the javascript function to be displayed beneath that.
thanks in advance,
geebee

obviously.... the output is defined in a function after all @geraldjr30
then there is something wrong with your PHP code.

document.write reopens the document for writing, so don't use it after the page has loaded. Either use DOM methods, set innerHTML of an element or use it during page load only.
ok... i think im almost there..
i have.. -
<?php>
-
...
-
...
-
?>
-
-
<SCRIPT LANGUAGE="JavaScript">
-
function showLoc()
-
{
-
var x = window.location;
-
if (x == "http://localhost/REC.php?count=sunday&fac=des&SRG_GROUP=Charity")
-
{
-
-
document.body.innerHTML += "<a href=\"http://www.AOL.com\">AOL</a>";
-
}
-
else
-
{
-
document.body.innerHTML += "<a href=\"http://www.msn.com\">MICROSOFT</a>";
-
}
-
}
-
</SCRIPT>
-
but neither AHREF is being shown on the page...
thanks in advance,

Are you calling showLoc body onload?
now i am calling it on BODY load.. but the MICROSOFT link is appearing. The url in the address bar is http://localhost/REC.php?count=sunda..._GROUP=Charity
so it should be listing the AOL link instead... am i evaluating the current url wrong? once again my code is... -
<SCRIPT LANGUAGE="JavaScript">
-
function showLoc()
-
{
-
var x = window.location;
-
if (x == "http://localhost/REC.php?count=sunday&fac=DES&SRG_GROUP=Charity")
-
{
-
-
document.body.innerHTML += "<a href=\"http://www.AOL.com\">AOL</a>";
-
}
-
else
-
{
-
document.body.innerHTML += "<a href=\"http://www.msn.com\">MICROSOFT</a>";
-
}
-
}
-
</SCRIPT>
-
thanks in advance,

try this one: - if (x.href == "http://localhost/REC.php?count=sunday&fac=DES&SRG_GROUP=Charity")
ok thanks... that works!!!! now all i need to figure out is to evaluate whether or not the url in the address bar is suffixed with "#top", as there may be any day followed by the word "count" in the url, and i would rather not have an if statement for ever day of the week. how would i amend this?
thanks in advance,
geebee

I've told you about that problem already in post #4 (and #6)........ @geraldjr30
use window.location.hash (see post #2)
regards
it works... but no matter how hard i try, i cant get the MICROSOFT or AOL link to appear at the top of the page... it appears off to the side of the PHP output... -
<BODY onload="showLoc();">
-
-
-
<SCRIPT LANGUAGE="JavaScript">
-
function showLoc()
-
{
-
var x = window.location.hash;
-
if (x == "#top")
-
{
-
-
document.body.innerHTML += "<a href=\"http://www.AOL.com\">AOL</a>";
-
}
-
else
-
{
-
document.body.innerHTML += "<a href=\"http://www.msn.com\">MICROSOFT</a>";
-
}
-
}
-
</SCRIPT>
-
thanks in advance,

it will be appended at the end.... looks like it. to get it on the top either use DOM methods to include the links or a different styling.
thanks...
how i get the page to refresh with the following: -
echo "<td width = '100' height = '10'><br><a href='#top'>back to top</a></td>";
-
thanks in advance,
geebee

besides clicking on the link?
i want it to refresh when you click on the #top link
Dormilich 8,658
Recognized Expert Moderator Expert
ah, try with the whole url. like href="localhost/this_page.htm#top".
will this work even if the url parameters are changed? like the url for this page could change depending on the form values posted to it from the previous page.

if you send the values via POST then you don't need to worry. you can get the URL in PHP via the $_SERVER variable (just check out phpinfo()). if I remember right it's $_SERVER['REQUEST_URI']. but others may do as well.
