I am hoping that this is a proper forum to post to.
I got an Ajax script from Dynamic Drive called "Dynamic Ajax Content" that loads external pages into a DIV in the Parent page. The effect is much like that of an iFrame.
I am loading videos into the target DIV.

All of that works fine, but visibility on the parent page seems to be a problem. By necessity, I must(?) place the div close to the bottom of the page. However, when I click on a link that loads the video, I would like to have the parent page "jump" to the DIV with the video.
It is probably easier to visualize this than for me to try to explain it:
http://www.inatheaternearyou.com/peak-moments/peak-moments.html

For instance, if you click on "The Natural", the video indeed loads, but it is not 100% viewable since it is at the bottom of the page.
I tried to emulate an <a name=#jump"> <a href="#jump"> scenario, but since javascript is controlling the generation of the Ajax window, it was to no avail (I am embarrassed to say my javascript skills have eroded a bit!).

Are there any lines of code that can be added to the javascript that will correct this problem?
Another alternative?

Here is the javascript:

I suppose i could solve this by having drop-down menus in lieu of the line-by-line ones my page currently is going with, but I like to have all the titles laid out, because people are less likely to go searching for something (and for SEO purposes).

Any help on this? :)

Rick

The anchor tag will actually work, you just don't know how to implement it.

Add this tag INSIDE your AJAX <object> element.

<object height="405" width="660">
	<a style="padding-right: 660px; position: relative; bottom: -15px; visibility: hidden;" name="jump">Video</a>
	<!-- The rest of your params and embed code -->
</object>

Then, when you use AJAX to load a video, add this to your JavaScript:

document.location.href = document.location.href.replace(/(?:#(?![^#]*\.)).*$/, "") + "#jump";

The reason for the extra regular expression is so that it removes the current anchor with the new one, and you don't get a URL searching for <a name="jump#jump">

Thanks for the help - I appreciate it :)

Spycat,

Itsjareds has just beaten me to it. My advice is just about the same, maybe a bit simpler (no RegExp needed).

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<title>Airshow :: Untitled</title>
<script>
function goToVideo(){
	location.hash = 'video';
}
</script>
</head>
<body>
<a href="" onclick="goToVideo(); return false;">Go to Video</a>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>

Note: <br>s (or other content) after the video ensure that the window can scroll far enough.

Spycat,

A small word of warning. Whether you use Itsjareds' code or mine, you have to pay attention to a subsequent form submission from the page. It may be better to set the form's action explicitly rather than rely on action="" to re-serve the same url (which the browser will request by default). The requested url may have its #video fragment still intact so the re-served document may jump to the video again (unless you take measures server-side, such as a redirect).

Of course:

  • If you submit a form with action="explicitlyThisDocumentWithoutTheHash" then you avoid the jump.
  • If you submit a form with action="anotherDodument" then this is all academic.
  • If you don't perform a form submission from the page then this is all academic.

I appreciate your help - thanks sos much! :)

Hi Jared,

Brilliant solution -- this seems to work really well.
The only alteration I did was increase the bottom margin from -15px to 50px to insure it picked up my writing below the video:

<object width="660" height="405">
  <a style="padding-right: 660px; position: relative; bottom: -50px; visibility: hidden; clear:both;" name="jump">Video</a>
    <param name="movie" value="http://www.youtube.com/v/Bmsfdx40eSc&hl=en&fs=1&rel=0&color1=0x2b405b&color2=0x6b8ab6&border=1&border=1" />
    <param name="allowFullScreen" value="true" />
    <param name="allowscriptaccess" value="always" />
    <embed src="http://www.youtube.com/v/Bmsfdx40eSc&hl=en&fs=1&rel=0&color1=0x2b405b&color2=0x6b8ab6&border=1&border=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="660" height="405"></embed>
  </object>

BTW, here is where I placed your regular expression.
I am assuming I put it in its proper place, seeing as it works well :)

function loadpage(page_request, containerid){
if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1)){
document.getElementById(containerid).style.display="none"
document.getElementById(containerid).innerHTML=page_request.responseText
document.getElementById(containerid).innerHTML=document.getElementById("clip").innerHTML
document.getElementById(containerid).style.display="block"
document.location.href = document.location.href.replace(/(?:#(?![^#]*\.)).*$/, "") + "#jump";
}

Here is the page in question.
All links are not set up yet, but the one for "The Natural" is:

Hi Airshow,

How's it goin'?
Thanks for your fast response.
I am intrigued as to the many ways the same goal can be reached thru multiple means.
I like your solution as well, but seeing as how I have been negligent in maintaining any javascript skills I may have had at one time, I am a bit confused as to which pages I should put your code on.
As the parent page calls the child page containing the video, I ask:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<title>Airshow :: Untitled</title>
The below goes into the Parent page, correct?
<script>
function goToVideo(){
	location.hash = 'video';
}
</script>
</head>
<body>
Which document does the below go into?
<a href="" onclick="goToVideo(); return false;">Go to Video</a>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>

I am guessing the code below with the named anchor would be the target for the above link, and would be placed on the Child Page, no?

<a name="video">Video</a>
<div style="width:150px;height:150px;background-color:#d9f4d2;border:3px solid #000000;"></div>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>
</body>
</html>

Note: <br>s (or other content) after the video ensure that the window can scroll far enough.

Airshow

Again, thanks :)

Spycat,

Mine was a very crude demo of how you can use javascript to go to a named anchor on the same page. It is virtually identical to Itsjareds' solution, which he kindly wrote in the context of your original code. (I was lazy).

There's no need to change Itsjareds' code but if you want to try, then change his line document.location.href = document.location.href.replace(/(?:#(?![^#]*\.)).*$/, "") + "#jump"; to document.location.hash = "jump" . Everything else in my demo page is just padding. .hash is a built-in property of URL objects, thus making the hash fragment individually read/writable.

Airshow

Yep, basically Airshow's method was much cleaner and involved writing no regular expressions. The way I went about it just re-invented the wheel -- I didn't know about the other way :P. I would advise you to replace my code with his, since his is much less (if not at all) error prone.

So, change my line:

document.location.href.replace(/(?:#(?![^#]*\.)).*$/, "") + "#jump";

To:

document.location.hash = "jump";

Both would be fine as long as your page isn't similar to facebook where it navigates through hash urls (does not change the page but adds #/newPage.html to the URL). Good luck with the rest of your site :)

itsjareds & Airshow,

I want to thank the two of you for taking the time to provide
solutions to my dilemma - I sincerely appreciate it! :)
Here is the page:

Take care & best wishes!
