JavaScript - Can't Find The Problem

Hi, I've been trying to code a javascript fonction that uses Window.find and I'm having problems doing exactly what I want. I don't know much of java and I understand that it's not everyone who's willing to do all the work for me so I'm looking for a very kind person here

I want it to find a specific string that won't change (so no use to prompt for it) in another existing page that would be loaded in a frame. When the string is found, a sound is played like an alarm. The entire thing should reload every like 5 minutes. That's the easy part. I'm having trouble with the "If found in the frame, play a sound part".

I don't think it's pretty hard to do, but hey, I can't do it. As I said earlier, I understand I ask for someone to do the whole thing for me but I'm willing to pay by paypal for the service. Let's say... I don't know, ten bucks should do it.

I think I've been clear with what I need but if not, please feel free to ask for more specifications. Thanks for your time.

This is the script itself - no error messages are generated.

Code:

<script language="javascript" type="text/javascript">

function getXMLHTTPRequest() {

try {
req = new XMLHTTPRequest();
} catch(err1) {
  try {
  req = new ActiveXObject("Msxm12.XMLHTTP");
  } catch(err2) {
 	try {
	req = new ActiveXObject("Microsoft.XMLHTTP");
 	} catch(err3) {
 	  req = false;
 	}
  }
}
return req;
}

var http = getXMLHTTPRequest();

function getCattle(animal_id){

var myurl = 'find_cattle.php';
var CattleValue=animal_id;
	var modurl= myurl+"?d="+CattleValue;
**************the alert returns the correct value from my selection and after than nothing, I never get my alert from the response portion
	alert("Looking For "+modurl);
*******

	http.open("GET", modurl, true);
	http.onreadystatechange=useHttpResponse;
	http.send(null);
}

function useHttpResponse(){
************It never gets to this response
	alert("Made It To Response");
	if (http.readyState == 4) {
		if(http.status == 200) {
			var ListValue = http.responseXML.getElementsByTagName("animal_id")[0];
			document.getElementsById('cattle_data').innerHTML = animal_id.childNodes[0].nodeValue;
			}
		}	 
}

</script>

thank you

Hello. Please excuse my ignorance but I am not too clued up on javascript. Im hoping someone may be able to help me out here.
I have managed to locate a script which will find text on a page, but I have a couple of requests.

Firstly the script will only search up. I would like the search box to be at the top of a page but the only way to get it to work correctly is placing it at the bottom of the page.

Secondly would some kind soul advise me how to place the script in an external file and then link to it.

Thanks in advance.

Hi All,
I have the date in 2009-10-24 format.can anyone tell how can I get the day of any particular date entered by user.

Thanks in advance...

function textSize(updown) {
var size = Number(readCookie('user-font-size'));
if (size == 0) {
size = 12; // No Cookie, Set A Default Size Of 12px
}
size = size + Number(updown); // Adjust The Current Size
if (size > 20) { size = 20; } // Stop At 13
if (size < 12) { size = 12; } // Stop At 10
writeCookie('user-font-size', size, 12); // Update The Cookie
document.body.style.fontSize = size + 'px'; // Set The Users Text Size
}


function writeCookie(name, value, days) {
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
var expires = '; expires=' + date.toGMTString();
} else {
expires = '';
}
document.cookie = name + '=' + value + expires;
}

function readCookie(name) {
name += '=';
var cs = document.cookie.split(';');
for (var i = 0; i < cs.length; i++) {
var c = cs[i];
while (c.charAt(0) == ' ') {
c = c.substring(1, c.length);
}
if (c.indexOf(name) == 0) { //-----------//
return c.substring(name.length, c.length); // Gotcha //
} //-----------//
} //------------//
return null; // Failed //
} //------------

cheers hope thats enough code

Ant.

This is a function designed to return an array of all elements in "body" with a particular tag name and class name. It works fine up until the if (needles.length == 0); { line, according to my debugging. It seems to fail there though and I can't figure out why. It's probably just some noob error that I've missed but I can't for the life of me find it

Thanks in advance for any help, it's greatly appreciated!


Code:

function getElementsByClassName(tagname, classname) {
  var haystack = document.getElementById('body').getElementsByTagName(tagname);
  var needles = [];
  var i;
  for (i in haystack) {
    if (haystack[i].hasClassName(classname)) {
      needles.push(haystack[i]);
      continue;
    }
  }
  if (needles.length == 0); {
    needles = 0;
  }
  return needles;
}

Hello,
I have recently started a website which tells visitor's IP address, location and others details. I want to add some more functions to it. I found no way to detect visitors Internet Service Provider (ISP) using PHP. I would like to know if there is any way to do so in Javascript.

Click the below link to view the site:

Hi all.
Is it possible to command a find in page search from another html?
I have a 'main page' and 'directory page'
The directory page has find in page command on it, so if users can open the directory link from the main page and then search that page using the find in page search box.
To speed this up, is there any way I can have a text box on my main page that when I enter text and submit that it carries across the text entry to the find in page box on the directory page and starts this search for me?
I need to complete this using javascript so if this is possible I would great appreciate any help.
Thanks

Any help would be appreciated.

I need some help finding a "find on page" script that will display the results in the middle of the page for IE. I have tried several different ones to no avail. The ones that work in all the browsers display the result in IE at the very bottom of the page. I am not very familiar with programing in Java and I am unable to modify any for my needs. The one I found that did work in IE didn't work in any other browsers. Please help, Thx

I was trying to sum every number in the array and I wrote this function:
Code:

function sumArray(array) {
  var total = 0, i;
  for (i = 0; i <= array.length - 1; i++) {
    if(typeof array[i] == "number") {
      array[i] += total;
    }
  }
  return total;
}

I don't know why but it always returns "0". In other words, the initial value of "total" (if it was 5, it returns 5 etc...). I really can not see what is wrong here, any suggestions?

Hi All,

Just a quick question!

Is it possible to have a text box input searching for the entered text on another webpage in the same way Find In Page would do?

I have a webpage that I want users to input an item, and that this will open the targeted webpage and bring you to (and highlight) the matched item(s) like find in page does.

Is this possible or is the easiest way to just make users open the link to the target page and just complete the find in page search there?

Thanks
Glen

Hi Guys & Girls,

I am looking for help with a technical issue, which my programmer can't find the answer to.

My website has a demonstration facility which allows a client to enter their website which then in turn creates a video transparency overlaying their own website.

The problem is some sites with Flash, overlay my transparency video so that you cant see my demo video.

Any ideas please.

Thanks

I have a problem finding Form in javascript.

document.getElementById('MyForm');

return "HTMLUnknownElement". But if I add a dummy form previous for the one I actually want to find, then:

document.getElementById('DummyForm'); returns "HTMLUnknownElement", and then
document.getElementById('MyForm'); Returns "HTMLFormElement", that is what need. But this unknown element, the dummy form creates a lot of other problems with my site so this solution is no good for me. Why cant I find my Form? Thanks.
