JavaScript - How To Output The Html Code From Javascript?

Hello all!

I'm having a bit of an issue here with my lastest project. What I'm trying to do is have a menu that a user would click one of two links which would change the targeted iFrame, then repeat for two more options, and again for two more.

It is essentially a filtering system for videos (the best way for you to see what I mean is to check out http://grph.cmwdesign.ca).

My actual issue here is the changing of the iframe href, and on top of that, I seem to not to be able to properly get my functions to run all the time.

Here is my Javascript:

Code:

		

		var categoryLink=new Array(); 
		var counter;
		var link = "";
		categoryLink[0] = "";   
		categoryLink[1] = "";   
		categoryLink[2] = "";   
		counter = "0";

$(document).ready(function() {
        $(".atonal").live('click', function() { {
          alert("sometext");
          		if (categoryLink[0]=="") {
					categoryLink[0] = "atonal";
					$("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
					
				
				else {
					categoryLink[0] = "";
					$("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
				}
          
        });
});

$(document).ready(function() {
        $(".tonal").live('click', function() {
          alert("sometext");
          		if (categoryLink[0]=="") {
					categoryLink[0] = "tonal";
					$("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
					
				
				else {
					categoryLink[0] = "";
					$("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
				}
          
        });
});


$(document).ready(function() {
        $(".being").live('click', function() {
          alert("sometext");
         categoryLink[1] = "being"; $("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
					
          
          		if (categoryLink[1]=="") {
					categoryLink[1] = "being";
					$("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
					
				
				else {
					categoryLink[1] = "";
					$("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
				}
          
        });
});

$(document).ready(function() {
        $(".doing").live('click', function() {
          alert("sometext");
          		if (categoryLink[1]=="") {
					categoryLink[1] = "doing";
					$("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
					
				
				else {
					categoryLink[1] = "";
					$("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
				}
          
        });
});


$(document).ready(function() {
        $(".abstract").live('click', function() {
                 alert("sometext");
          		if (categoryLink[2]=="") {
					categoryLink[2] = "abstract";
					$("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
					
				
				else {
					categoryLink[2] = "";
					$("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
				}
          
        });
});

$(document).ready(function() {
        $(".documentary").live('click', function() {
                 alert("sometext");
          		if (categoryLink[2]=="") {
					categoryLink[2] = "documentary";
					$("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
					
				
				else {
					categoryLink[2] = "";
					$("a.frame").attr('href', categoryLink[0] + categoryLink[1] + categoryLink[2]);
				}
          
        });
});

and the HTML in question:

Code:

<table>
<tr>
<td height="35" width="210" valign="top">choose your sound</td>
<td width="165" valign="top"><a href="#" id="atonal">atonal sounds</a></td>
<td width="165" valign="top"><a href="#" id="tonal">tonal sounds</a></td>
</tr>
<tr>
<td height="35" width="210" valign="top">choose your text</td>
<td width="165" valign="top"><a href="#" id="being">being words</a></td>
<td width="165" valign="top"><a href="#" id="doing">doing words</td>
</tr>
<tr>
<td height="35" width="210" valign="top">choose your image</td>
<td width="165" valign="top"><a href="#" id="abstract">abstract images</a></td>
<td width="165" valign="top"><a href="#" id="documentary">documentary images</a></td>
</tr>
</table>

I'm no Javascript wiz, so I'm sure I'm probably not going about this entirely the correct way. Any suggestions would be great!

I'm programming a function that breaks a massive string (2 million + characters) into "manageable" chunks of 500,000 characters. The function goes as follows:
Code:

var json_string = "{'action':'message-send','recipients':recipients,'message':message";
			var bytes_chunks = scripting.messages.voice.recorder.bytes.chunk(500000);
			$.each(bytes_chunks,function(i,v){
				json_string += ",'voice_bytes_"+i+"':'"+v+"'";
			});
			json_string += "}";

As you can see, everything should work fine, and the function should return a stringified json array (which would be parsed and sent to a server) but the string is truncated and function exited after the first interval. When I decrease the length of "v" using substr to 5 characters, all the expected children are returned. What could the problem be?

I have a very basic calculator that I am trying to make that takes info from radio buttons (i.e. 1 for bad 5 for good) and outputs an average or score at the end, but its not working correctly. I have changed the last line to output what the total number is not the average, to see if it is outputting the correct number, and its not... It says "[object HTMLInputElement]"... Any thoughts will be greatly appreciated! Thanks!

function calcScore(){

Hi There,

I really need your help.

How could I amend the following code below to incorporate the fieldnames on the top before displaying the values of the recordset?

Ie.

[FIELDNAME1] [FIELDNAME2] [FIELDNAME3] [FIELDNAME4]
value1 value2 value3 value4

Code:

<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>New Page 1</title>

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

function getsqltable() {

  	var strtable = ""
	var cn = new ActiveXObject("ADODB.Connection")
	var rs = new ActiveXObject("ADODB.Recordset")
	var dbfile = "imts.mdb"
	var dbPath = "F:/PROJECTS/IMTS PROJECT/V7/database/"

	cn.Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source = " + dbPath + dbfile + "")
	
	var mySQL = "SELECT * FROM tbl_imts WHERE [File Number] = 'A-2010-00301'"
       
    rs.Open(mySQL, cn, 1, 3)

    rs.MoveFirst
    
       strtable='<table cellpadding=0 cellspacing=0 width=75%>';
       while (!rs.eof)
       {
           strtable+='<tr>';
           strtable+='<td>'+rs.fields(0)+'</td>' + '<td>'+rs.fields(1)+'</td>' + '<td>'+rs.fields(2)+'</td>' + '<td>'+rs.fields(3)+'</td>'
           strtable+='</tr>';
           rs.movenext;
       }
       strtable+='</table>';
       
       
       rs.close;
       cn.close;
       
       document.getElementById('htmltable').innerHTML=strtable;
   }
   </script>


</head>

<body>

   <input type="button" onclick="getsqltable();" value="Click Me"/>
   
   <div id="htmltable"></div>
   
</body>

</html>

I've tried modifying the while code, but it puts it all on one line:

Code:

       while (!rs.eof)
       {
           strtable+='<tr>';
           strtable+='<td>'+rs.fields(0).Name+'</td>' + '<td>'+rs.fields(1).Name+'</td>' + '<td>'+rs.fields(2).Name+'</td>' + '<td>'+rs.fields(3).Name+'</td>'
           strtable+='<td>'+rs.fields(0)+'</td>' + '<td>'+rs.fields(1)+'</td>' + '<td>'+rs.fields(2)+'</td>' + '<td>'+rs.fields(3)+'</td>'
           strtable+='</tr>';
           rs.movenext;
       }

any ideas?

Much thanks and appreciation for everyones help.

Cheers and much thanks in advance,

Jay

Hey Everyone,

Thanks for reading my thread, I really hope I'm not asking a dumb question as I am teaching myself java but here goes. I'm a bit stuck and want my code to output a message when a form input does not contain a word (like lets say codingforums.com). I know it outputs my message when the field is left blank but here's what I have, any help will be greatly appreciated

Thanks.

Code:

function checkPostFields(form) {
	
	var msg = '';
	var value_missing = false;

	if (form.elements['test'].value == ''
			) {
		msg += '<?php echo $errormessage; ?>\n';
		value_missing = true;
	}
}

i have borrowed a java script to produce a weather forecast using data from my weather station.

}
//-->
</script>


</body>
</html>
this basically turns my PHP variables intoa forecast by using the script above and also sager_cast.js (which crunches the numbers).

my question is how can i record the output to a text file

ie. this bit

Quote:
<br />
Sager =
<span id="forecast">forecast will appear here</span>
i know how to run a cron job on my host server but whenever i try to use php to geta at it, it fails.

i understand that php and JS and side server / client server / host server different, but surely there must be a way to record the output using my host and the script that i have.

my goal is to catch the forecast every 15 mins (with a time stamp) and then look back at the (text) file to see how it has changed.

can anyone please help?

one suggestion is to turn the number crunching JS script into php so i can 'get at it' but there are thousands of lines of code!

thanks in advance, and hello from a newbie poster!

Hi Guys,
I want to output my pagetitle in javascript. An idea of syntax?

<title> products</title>

eg My page title is javascript code
outputs...
My page title is products

no joy with
Code:

<body>
<script TYPE="text/javascript"> 
document.write(document.title); </script> 
</body>

Thanks

OK,

There's a script on my site that's included like <script src='somePHPfile.php?params... etc

It generates an image with some text in it and a few links.

When I click 'view source' it just comes up with the <script> tags and nothing else. In Firefox, if I right click on the actual image and go to this frame > view source, I can see everything it's doing.

Is there some way I can access this code with Javascript/jquery? I've tried html/dom parsers, etc. with no luck.

Firstly I know this is a PHP issue yet it is within javascript and IMO is the root cause of the problem.

I'm trying to output markers from a search query of locations from my database, onto a Google Map (api v.3) using a tut I found http://tips4php.net/2010/10/use-php-...g-data-on-map/

When adding this to my page I'm getting Undefined index:errors.

I have changed the variables in the php part of the script to suit my database yet have left everything else alone, cant figure out why I'm still getting a blank map????

Please help....

My code with errors being shown at bottom;

Code:

<script src="http://maps.google.com/maps/api/js?v=3&sensor=false" type="text/javascript"></script>
<script type="text/javascript"> 
 var icon = new google.maps.MarkerImage("http://maps.google.com/mapfiles/ms/micons/blue.png",
 new google.maps.Size(32, 32), new google.maps.Point(0, 0),
 new google.maps.Point(16, 32));
 var center = null;
 var map = null;
 var currentPopup;
 var bounds = new google.maps.LatLngBounds();
 function addMarker(lat, lng, info) {
 var pt = new google.maps.LatLng(lat, lng);
 bounds.extend(pt);
 var marker = new google.maps.Marker({
 position: pt,
 icon: icon,
 map: map
 });
 var popup = new google.maps.InfoWindow({
 content: info,
 maxWidth: 300
 });
 google.maps.event.addListener(marker, "click", function() {
 if (currentPopup != null) {
 currentPopup.close();
 currentPopup = null;
 }
 popup.open(map, marker);
 currentPopup = popup;
 });
 google.maps.event.addListener(popup, "closeclick", function() {
 map.panTo(center);
 currentPopup = null;
 });
 }
 function initMap() {
 map = new google.maps.Map(document.getElementById("map"), {
 center: new google.maps.LatLng(0, 0),
 zoom: 14,
 mapTypeId: google.maps.MapTypeId.ROADMAP,
 mapTypeControl: false,
 mapTypeControlOptions: {
 style: google.maps.MapTypeControlStyle.HORIZONTAL_BAR
 },
 navigationControl: true,
 navigationControlOptions: {

 }
 });

Hi,

I am not entirely sure what I am doing wrong here, and I have been looking at this for ages, so apologies in advance if I have become so bleary eyed I can't see something simple.

I use php to create buttons based on values pulled for a table. The problem I have is when you click on the first button the javascript function works great, when you click on the next button you get the same output even though it should be different results. I am working in ff and I can see on my firebug console that the javascript function is being called, but it is not passing the new value of the second or third button, it just keeps repassing the value of the first button. So not entirely sure where I am going wrong here.

My page is:
Code:

<script type="text/javascript">
function loadXMLDoc2(File,ID,Msg){
if (window.XMLHttpRequest)  {
  xmlhttp=new XMLHttpRequest();
  }
else {
	try{
  xmlhttp=new ActiveXObject("Msxml2.XMLHTTP");
  } catch (e) {
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }	
}

xmlhttp.onreadystatechange=function(){
  if (xmlhttp.readyState==4 && xmlhttp.status==200){
    document.getElementById(ID).innerHTML=xmlhttp.responseText;
    }
  }

var params=Msg;
xmlhttp.open("POST",File,true);

xmlhttp.setRequestHeader("Pragma", "Cache-Control:no-cache");
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.setRequestHeader("Content-length", params.length);
xmlhttp.setRequestHeader("Connection", "close");
xmlhttp.send(params);
}
</script>
<head>
<body>
<?php

	$con = mysql_connect("localhost","user","password");
	if (!$con)		{
		die('Could not connect: ' . mysql_error());
		}
	mysql_select_db("mydb", $con);

	$result = mysql_query("SELECT DISTINCT theme FROM goods	WHERE category='{$_POST['category']}'
	ORDER BY theme DESC");
	

	while($row = mysql_fetch_array($result)){
		echo '<input type="text" class="hidden" name="theme" id="theme" value="' . $row['theme'] . '" ><input type="button" class="button3" name="product" id="product" value="' . $row['product'] . '" onClick="loadXMLDoc2(\'getShow.php\',\'txtHint\',\'theme=\'+encodeURI(document.getElementById(\'rtheme\').value))" >&nbsp';
		}
echo '<br /><br />

<div id="txtHint"><div>
<br />
<br />';

	mysql_close($con);
?>

And getShow.php produces a table with a list of product images, names and prices, based on theme.

So basically not sure where I am going wrong here?

Hi Guys,
I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled!
I create the following code but it did not work

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>New Web Project</title>
<script language="JavaScript" type="">
function changeColor(){
document.bgColor = "Gray";
}
</script>
</head>
<body>
<script language="JavaScript" type="text/javascript">
var person = "";
person = prompt('What is Your Name:');
if (person == "Foo") {
document.write("<h1 />Welcome " + person);
document.bgColor = "Yellow";
}
else {
document.write("<h1 />Access Denied!!!!");
document.bgColor = "Red";
document.getElementById("gree").disabled = true;
}
</script>

<div>
<p/><input id="gree" type="button" value="Gray " onClick="changeColor();">
</div>
</body>
</html>

as you can see I used the:
document.getElementById("gree").disabled = true;
but it did not work , could you please give an idea how I can solve this problem?
Thanks
