JavaScript - Textarea Onchange Detection

Good day!

I have an intranet website that was in the server and it has a flash. My problem is the client computer has no flash installer; I want that they can access the flash.exe in the server so they can install it to their computer. I read some forum that it could happen using JavaScript detection code. Honestly I have no idea about it.
Thank you

Hey,
I'm working on a mobile website and need some help with my mobile browser detection script. I have it working for iPhone, iPod Touch, and Windows Mobile Devices.

I need help getting it to detect for Blackberry Browser (Blackberry Devices), Blazer Browser (Palm Devices), Opera Mini Browser, Opera Mobile Browser, and other mobile browsers if possible.

Does anyone know how to modify (and test if you have a phone to test with, as I don't have all of these devices) this javascript?:
Code:

if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)))
{location.replace("mobile.html");}
if((navigator.appVersion.indexOf("Windows CE")>0))
{location.replace("mobile.html");}

Thanks for your help!

I have a website (www.andrewburns.net.au) that displays differently according to OS. Currently in OSX the text in the menu lines up with the image text of the site title - this is what we want to have happen and it looks fine across all browsers using OSX. However, in Windows it's offset by about 10px, and similarly displays the same offset in all Windows browsers incl Chrome, FF, Safari, and of course ie.

I'm trying to use javascript to sniff out the OS and display alternate css accordingly. I'm not a JS coder at all and a friend who is has got me this far...

Code:

var isms=( navigator.appVersion.indexOf("Windows") != -1);
document.write("Browser Version: " + isms);
if(isms) $('DIV .menu').css('left','100px');

What I'm not sure about is where to put it to make it work given there is a fair amount of other scripts operating on the site.

Is there anyone out there who can have a look at the site/source code and offer any insight/suggestions/solutions? I'd really appreciate it... I'm under a fair bit of pressure from the designer to get it pixel perfect and this is the last aspect of the site to sort out before I can sign it off.

Thanks

I'm looking for a javascript that will detect the following user information: OS version, browser version, quicktime + flash + adobe reader + java + windows media player + sliverlight versions of the users computer.

I am looking to put this script into an HTML page and the information be displayed so the user can see what versions of the programs they have. I don't know a whole lot about javascript so if there is a script i could copy and paste, that would be great!!!!

Also, is it possible to have the current versions of these programs displayed and automatically updated as well so the user can compare the version they have with the most current version of the program?
Any help would be great! Thanks!!!

Greetings,

I'm working on a php/mysql app that has multiple tabs with multiple form fields. I am trying to incorporate a javascript form field detection function that alerts the user that they have not submitted their changes if they try to navigate away. The detection works as designed, but the problem I am having is when the form is submitted, the script senses an unload and still fires the alert. The form submits to itself and updates the database and then reloads the page with the new values. Is there a way to have the script ignore the forms submit url and skip the form check?

Here is the code ( NOT mine, found it somewhere else.)

Code:

<script language="javascript">
  var ids = new Array('description');
  var values = new Array('<?php echo $detail['description']; ?>');
  
  function populateArrays() {
    // assign the default values to the items in the values array
    for (var i = 0; i < ids.length; i++) {
      var elem = document.getElementById(ids[i]);
      if (elem)
        if (elem.type == 'checkbox' || elem.type == 'radio')
          values[i] = elem.checked;
        else
          values[i] = elem.value;
    }      
  }
  var needToConfirm = true;
  
  window.onbeforeunload = confirmExit;
  function confirmExit() {
    if (needToConfirm) {
      // check to see if any changes to the data entry fields have been made
      for (var i = 0; i < values.length; i++) {
        var elem = document.getElementById(ids[i]);
        if (elem)
          if ((elem.type == 'checkbox' || elem.type == 'radio') && values[i] != elem.checked)
            return "Your changes have not been saved. Are you sure you want to leave?";
          else if (!(elem.type == 'checkbox' || elem.type == 'radio') && elem.value != values[i])
            return "Your changes have not been saved. Are you sure you want to leave?";
      }
      // no changes - return nothing      
    }
  }
</script>

The url of the page is "edit.php?&mode=edit&t=2&id=284&cn=2009-002"
The only detectable change to the query string would be the 't' variable.

Basically what I want to do is have the script look for a change in the 't' variable and if detected, check the form values for changes. If 't' doesn't change, skip the script completely.


Thanks..

i don't know what has changed in last releases of Firefox and Opera
but before i used this script to detect browser versions (IE, Opera, FF)
and block or redirect depending on version

Code:

 <script language="javascript">
 <!--

//Detect IE greater than 1 - we are blocking it completely
version=0
if (navigator.appVersion.indexOf("MSIE")!=-1){
temp=navigator.appVersion.split("MSIE")
version=parseFloat(temp[1])
}
if (version>1)
window.location="ie-error.html"


//Detect Opera less than 10 (9.80)
if (navigator.userAgent.indexOf("Opera")!=-1){
var versionindex=navigator.userAgent.indexOf("Opera")+6
if (parseInt(navigator.userAgent.charAt(versionindex))<9.8)
window.location="op-error.html"
else (window.location="index2.html")
}

//Detect Firefox less than 3.6
if (navigator.userAgent.indexOf("Firefox")!=-1){
var versionindex=navigator.userAgent.indexOf("Firefox")+8
if (parseInt(navigator.userAgent.charAt(versionindex))<3.6)
window.location="ff-error.html"
else (window.location="index2.html")
}

// -->
</script>

it worked last with Opera 9.5, FF 3.0
but after that it doesnt work at all
Firefox'es version (3.6) doesn't get detected and is redirected to error page
same goes with Opera (9.8 which is 10.0-10.5)

can anyone tell me why this happens ?
or can anyone "fix it"

i know many people are against this kind of scripts (blockers and redirecters)
but i do it so people who come with older and less compatible browsers with
W3C standards to get warned so they don't load deformed page

hey guys i'm making a lunar lander game using javascript.i want the player to land the spaceship on a black line i've drawn. but i have problems getting it right.when the player lands it properly in the line i want it to display a dialogue box which says u landed it perfectly.but the problem is even if i land it outside the line it gives me that message.so after spending sometime with it i figured out that my if statement is not working properly.it doesn't take the value from my x axis and only considers the value from my y axis.for eg lets say i drew the line from 560px to 600px on the x axis and its located at 700px on the y axis and this is my if statement
if((TopPos>695)&&(rightPos>560)&&(rightPos<600))
{
alert('you landed perfectly')
}

this is supposed to work but if i go above 600px but still maintains the height above 695 it says i have won.i have included the code could some point me out where i'm making the mistake thank you .

Code:

<html>
<head>
<title>Lunar lander</title>

<script language="JavaScript"> 
var TopPos=100;
var fuel = 300;
var gravity = 0.0001;
var speed = 0.0005;
var moveBy = 366;
var Xpix = 1000;

function animation(){
TopPos +=gravity

document.getElementById("divlander").style.top = TopPos + "px";
if ((TopPos>604)&&(Xpix<526)){
			alert('win');
	}
	else if ((moveBy<100)&&(moveBy>500)){
			alert('crashed');
	}
if(TopPos<610)
window.setTimeout("animation()",30);
gravity +=0.03;
gravity += speed;
var f = document.game.fuel.value;
f--;
document.game.fuel.value = f;
if (f<=0){
document.game.fuel.value ="0";
gravity=10;
gr=0;
speed=10;
f=1;
alert('out of fuel');
}
}
function moveObj(name, Xpix, Ypix) 
{    
   	obj = document.getElementById(name);
	
	px = parseInt(obj.style.left) + Xpix;		
	py = parseInt(obj.style.top) + Ypix;
	obj.style.left = px;
	obj.style.top = py;
}

function ProcessKeypress(e)
{
	var myObj = "divlander";
	var moveBy = 10;
	
	if (e.keyCode) keycode=e.keyCode;
	else keycode=e.which;
	ch=String.fromCharCode(keycode);
   
	if(ch=='a') 		moveObj(myObj, -moveBy, 0);
	else if(ch=='d') 	moveObj(myObj, moveBy, 0);
	else if(ch=='w') 	gravity = -1;
	
		
}

Hi,

I need a javascript that detects flash and replace z-index value.

i have 2 div. div1 (alternate HTML content) has z-index=-3 and div2 (flash object) z-index=0. If flash is detected, do nothing. if flash is not detected, i would like to set div1 z-index to a positive 3.

can someone please help me?

Hello,

I'm trying to write some javascript that will detect if the page has been loaded because of the refresh button being pressed. I've searched google on how to do this, and several websites recommend something similar to the code I'm implementing below:

Code:

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

// in head

    function checkRefresh() {

        alert("BEFO  value = " + document.getElementById("visited").getAttribute("value"));

        if (document.getElementById("visited").getAttribute("value") == null ||
            document.getElementById("visited").getAttribute("value") == "")
        {
            document.getElementById("visited").setAttribute("value", "refreshed")
        }


        alert("AFTER: value = " + document.getElementById("visited").getAttribute("value"));
    }

</script>

...

<body onload="Javascript:checkRefresh();">

...

    <form id="hiddenform">
    <input type="hidden" id="visited" value="" />
    </form>

</body>

My variation differs from most of the examples on the internet in a few ways (which may or may not affect its functionality):

1) Most examples access the elements by directly using their names (as in: document.hiddenForm.visited.value). I'm using document.getElementById(...).getAttribute(...) just because that seems to be the safest way to ensure you are in fact getting the elements you want, and setAttribute(...) to ensure you're setting the attribute in the proper way. This entails that I need to set the ID in the form and input elements rather than the name.

2) I'm accessing the input tag directly (rather than going through the form) because I really don't see how this would make a difference.

3) I'm doing all this within asp:content tags which, from what I understand, can affect the behavior of the elements within it.

I'm not sure if this works out for other programmers, but for me it doesn't seem to be working. My alert messages in the checkRefresh function tell me that the value of the input element does indeed change as expected, but it seems to get wiped out and reinitialized to the original value of "" when the page is refreshed.

Am I doing something wrong?

Thanks for any help.

Hello,

Is there a way with JavaScript to easily detect which mobile browser is being used? I would not normally ask this, but because we do not have the time or budget to implement any back end detection scripting it is our only option right now!

I don't think we will need to detect which version of the browser, or which revision of the phone is used - just need to target each family to deliver the proper video type.

Hi all,

Background:

I'm currently working on a landing page which will display the same on both desktop & mobile devices, which is what we "want" for now.
However, we've created an alternate registration page for mobile devices. This page can be accessed by clicking on a specific button, which has a class on it that will determine if the user is on a mobile device or not. If they are not, the normal action will occur, such as a registration popup, built specifically for desktop users.


The problem is:
I'm firstly having to use .remove to take away the class of pbx_ajax which operates the popup, so mobile users aren't affected by the popup and will continue onto the page we specially built for them. However, it seems my script is removing the class straight away, which prevents the popup from working for desktop users. Secondly, the script doesn't actually seem to work, it simply doesn't fire, which begs the question if i've cocked up my class bind.
Code is attached below, please if anyone has any advice, do let me know as i'm at my wits end.

Oh and i'm sure you'll notice, i'm polling for when the jQuery has loaded, as the library is located at the bottom of our site (its a rather large site).


The javascript/jquery
Code:

//$(document).ready(function() {
	//Global function that will detect what device the page is being viewed on
	function globalDetectDevice() {
		var deviceIphone = "iphone";
		var deviceIpod = "ipod";
		
		//Initialize our user agent string to lower case.
		var uagent = navigator.userAgent.toLowerCase();
		
		
		//**************************
		// Detects if the current device is an iPhone or iPod Touch.
		function DetectDevice()
		{
		    if (DetectIphone()) {
		    	window.location = "/landing/register/mobile" ;
		    }
		    else if (DetectIpod()) {
		    	window.location = "/landing/register/mobile" ;
		    }
		    else {
		    	return false;
		    }
		}
	}
	
	//Binding the above function to a class, that we can then attach to any clickable element
	//As jQuery is at the bottom of page, we poll the function until jQuery has loaded, once loaded, we clear the polling using clearTimout
	var bindTimer = setInterval(function() {
	    if ("undefined" != typeof jQuery && globalDetectDevice) {
	        $('.detectDevice').removeClass('pbx_ajax').bind('click', DetectDevice);
	        clearTimeout(bindTimer);
	    }
	}, 50);
//}

the html button
Code:

<a class="detectDevice pbx_ajax" title="Join Free" href="?cat=popup&amp;action=open&amp;settings=pbx_popup_register">~graphic("btn-get-started-prints-LP")</a>

thanks for any help

Hi i have a problem, i've been trying to fix this for the whole day

pls see my code below

Code:

for ($o = 0; $o <= $totalclass; $o++) 
{ 
	for($i = 1; $i <= 45; $i++)
	{
		if ($_SESSION['classification'][$o] == $i) 
		{
			$sql2="SELECT ClassDesc FROM tblclass WHERE ClassID = '$i'";
			$result2=mysql_query($sql2);
			
			// If successfully queried
			if($result2)
			{
				while ($row2 = mysql_fetch_assoc($result2)) 
				{
					$ClassDesc2 = $row2['ClassDesc'];
				}
			}
			//echo $ClassDesc2;
		?>
			<tr>
			<td bgcolor="FAFAF6" class="small" valign="top">Class <? echo $i; ?></td>

			</td>
			</tr>
		<?			 
		}
	}
}

i've trying to create a button or image to reset one textarea (from whole array) and so far i've been unsuccessful.

i've seen this on other website and i know it is possible to do this, pls help!

Hi folks.

I'm working on a calculator and need to use the 'onchange' function.

Basically, the user selects the year (id=taxYear) and once the year is select (default is 2008) this year will appear in 2 different lines of the page under 2 seperate ID's(ageYear & totalYear).

I've looked at a few example of the function but I'm still not sure how to approach it.

At the moment the year changes once I hit the 'calculate' button but the onChange would obviously offer a better alternative with the date changing once 'taxYear' is changed.

here is the script;

Code:

 	//check the year 
	var taxYear =       document.getElementById('taxYear').options[document.getElementById('taxYear').selectedIndex].value;
	document.getElementById('ageYear').innerHTML = taxYear;	
	document.getElementById('totalYear').innerHTML = taxYear;	

Here is the jsp;
Code:

    <tr>
      <td align="left" width="203" colspan=""><p> Your Tax Year: </p></td>
      <td align="left" 	>      	
        	<s:select name="taxYear" id="taxYear" list="#{'2008':'2008', '2009':'2009'}" theme="simple" />*        
      </td>
    </tr>

    <tr>
      <td align="left" width="203"><p> Age at December 31st <span id="ageYear"></span></p></td>
      <td align="left" colspan="1">
        	<s:textfield name="age" id="age" theme="simple" cssClass="text" value="30" /> *
        	<div id="errorage" class="warningmessage" style="display:none">
        		Please enter your Age to proceed.
        	</div>
      </td>
    </tr>
        
    <tr>
    	<td colspan="2" class="basicboldtext">
    		<br/>
    		The total pension contribution you can make for year <span id="totalYear"></span>&nbsp;is &euro;<span id="totalTax2"></span>
    		<br/>
    	</td>
    </tr>

Appreciate any help on this!

Code:

<input type = "text" style ='display:none;' onchange="display_data_from_server(this.value)"/>

Value inside that input is cahanged from js.

Is there any reason that onchange would not happen ?
i mean, it does not.

I have a onChange value Code:

   
var people = [
        ["Timothy Conner", "1999-Present", "Age: 12", "Male", ""],
        ["Andrew Conner", "1992-Present", "Age: 19", "Male", ""]
    ];

var how = "Brothers";

function find()
{
   if(document.getElementById("name").value == people [0] [0])
   {
      document.getElementById("desc").value = people [0] [1] + "   " + people [0] [2] + "   " +  people [0] [3];
   }
   if(document.getElementById("name").value == people [1] [0])
   {
     document.getElementById("desc").value = people [1] [1] + "   " + people [1] [2] + "   " +  people [1] [3];
   }
    document.getElementById("relateb").value = document.getElementById("name").value;
}

Code:

Name: <input type="text" id="name" value="" onChange="find()"/>

So for it to proses a name you must click out of a box is ther a way to make it instead of when you click out of it, it would immidiatly change?
