Hello, I am trying to access HTML DOM elements in a remote window using JavaScript and getElementsByTagName but the resultant arrays are undefined.
<pre>
var remoteWin = window.open(URL,'rmtWindow');
remoteTags = remoteWin.document.getElementsByTagName("<tag>");
localTags = self.document.getElementsByTagName("<tag>");
</pre>
This works fine for localTags but not for remoteTags.
Am I not referencing the remote window correctly?
Also there seems to be some inconsistency in returned values:
<pre>
<a href="href URI string" param="hvalue"><img src="img URI string" param="ivalue"></a>
getElementsByTagName("a") returns the full "href URI string" string but getElementsByTagName("img") returns "[object HTMLImageElement]"
</pre>
I want to retrieve and manipulate the actual text strings of these elements, i.e., I want to access "img URI string", "hvalue" and "ivalue". I assume that I need to access properties of "[object HTMLImageElement]" to obtain the strings, including the strings for the optional parameter strings, but where or how do I find the definition of these properties?
Is there a way to associate the returned value for each embedded "img" element with its encapsulating "a" element? It is highly unlikely that the array indicies will match.
[Edit] Is the "img" element a child of the "a" element? If so I can associate them that way.
Thank you for your help, Art
[Edit] Firefox did not complain about this code, just left the values "undefined".
Opera [9.6], throws an exception and says "Security error: attempted to read protected variable".
Yet neither gives me any trouble when I write to a remote window. What's going on???

Hello,
I am part of a Volunteer Fire Department and have been tasked with coming up with a way to train the members how to properly use their two way radios on the fire scene.
To do this I would like to create a website that shoots out a Scenario to a member sitting in front of the computer with a radio in hand, He must communicate to another member sitting at another computer viewing the same training site. Once the second member receives the message over the radio he would click on a button on the site that would register what message was received and the "Trainer" can score if it was a correct transmitting by what the receiving operator clicked.
This is just a basic explanation of what I want done, I slightly knowledgeable in PHP and HTML but would need some help in designing something like this, I believe storing the information in a database would be the best bet.
Therefore I am looking for someone who is interested in helping the Fire Department to build this web tool.
Please let me know if you are interested in helping with this project, or provide any helpful feedback on the best approach to this project.
Thank You.

Depending where you are located, you might want to contact your local universty and find out if their computer science department supports "Senior Projects", where a team of senior computer science majors are assigned to you to solve your problem. They are graded on the completed project. Cool idea. The students get a chance to solve a real-world problem and you get a system built for free !
Just an idea ...

Good Idea but the closest university is about an an hour away and they don't have any web courses or anything offered.
|
|
|
|

When it comes to making websites the designers can be on the other side of the world to their client - often the two never meet - I agree that a university option would be your best bet for a free site. you could also ask around for friends of friends that are web designers who may be able to give you a basic mates rates site.

Replace your

There is an option in dreamweaver or many editors to replace text of all files in a particular folder.
Hope this will help.

var marqueeWidth='950';
var marqueeHeight='18px';
var pauseMarquee=true;
var fontFamily = 'arial,sans-serif';
var marqueeSpeed=1;
var speedTwo=marqueeSpeed;
var textSpan, marquee;
var fontSize = parseInt(marqueeHeight) - 6;
function marquee(){
var content = document.getElementById('scroller').getAttribute('content');
if (document.getElementById){
var scrollit = '<div style="position:relative; margin:auto; width:'+marqueeWidth+'px;height:'+marqueeHeight+';overflow:hidden;color:#FFFFFF;"';
if (pauseMarquee) scrollit += ' onmouseover="speedTwo=0" onmouseout="speedTwo=marqueeSpeed"';
scrollit +='><div id="marquee" style="position:absolute;left:0px;top:0px;font-family:'+fontFamily+';font-size:'+fontSize+'px;white-space:nowrap;"><\/div><\/div>';
document.getElementById('scroller').innerHTML = scrollit;
marquee = document.getElementById("marquee");
marquee.style.left=(parseInt(marqueeWidth))+"px";
marquee.innerHTML='<span id="text">'+content+'<\/span>';
textSpan = document.getElementById("text").offsetWidth;
setInterval("scrollscroller()",17);
}
}
function scrollscroller(){
marquee.style.left = (parseInt(marquee.style.left)>(-10 - textSpan)) ?parseInt(marquee.style.left)-speedTwo+"px" : parseInt(marqueeWidth)+4+"px";
}
window.onload=marquee;
That js should get you started - you need to change it so that it goes up and down not left though.

Hello,
I have a div, supposed the be at the bottom of the page, since its position is relative and there are another 2 divs placed before it. However it is diplayed at the top of the page. It is like that, in order to sva space I discarded the elements. The problem is, div footersub behaves like there are not leftsub or rightsub.
Please help.
Thanks alot.
<div id="centrallarge">
<h1 style="height:45px; width:900px;"><img src="images\digersayfa.jpg" alt="photo"/></h1>
<div id="central" style="Width:900px; margin-top:2px; height:700px;">
<div id="leftsub" style="Width:300px; height:650px; margin-top:50px;">
</div>
<div id="rightsub" style="Width:550px; height:700px; font-family:Tahoma; font-s
</div>
<div id="footersub">
</div>
</div>
</div>
|
|
|
|
|
Use this CSS on the page:
html,
body {
margin:0;
padding:0;
height:100%;
}
#centrallarge {
min-height:100%;
position:relative;
}
#footersub {
position:absolute;
bottom:0;
width:100%;
height:60px;
}
This will work in most of the browser.

I am writing a web-based system with java. There are some labels and reports printing. Each requires different printers which are connected to the same client computer.
How could I set so that, when I Print Doc A, document A would print to printer A, and when clicked Print for Doc B, document B would print to printer B.
The URL for both the documents are different. doc A is on http://www.xyz.com and doc b is on http://www.abc.com.
info: It is a web-based system used within a lan. So each user use the system with a fixed computer.

If you are using standard html in browser there is no way to force print the document in a printer of your choice. You can give alert to choose the printer of your type before calling window.print, which will open the print dialog.
After that it is on user's choice to use proper printer or not.
|
|
|
|
|
If you are sure that the web application will only run in lan, you can use PrintDocument classes to print the document from the server computer rather than invoking the browser print function.
This way you will eliminate the user's choice of printer selection. But mind that the printers should be connected to your server where the application is hosted. ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Hi Abhishek,
I am not sure how to use PrintDocument classes. Can you please guide me how to go about it.
Thanks.
|

Create An object of PrintDocument, draw on the Document using Graphics object, print the document.
http://www.dreamincode.net/forums/showtopic71580.htm[^]
check this .. This might help. but it is written in VB.NET.
Another way is to generate Reports and print the resource.
|
|

|

Hi Abhishek,
Thanks for your reply.
The object which is mentioned at http://www.dreamincode.net/forums/showtopic71580.htm, is for printing the pdfs.Our Reports are in pdfs, so I think we can print those using system default printer, I would like to change the printer for labels. I think that would be the easier approach.
Let me know your view.
Thanks.
