Getting Undefined Using $_get Function	View Content

Hi..

I encountered problem in using $_GET to get the DATE_PROCESS.

here is my code:

Code:

<script>
function editloan(){

var dateprocess = document.getElementById('dateprocess').value; 

alert(dateprocess);
window.location = "SSSLoan.php?dateprocess="+dateprocess;
}
</script>

Code:

<div id="searchname">
<form>

New to javascript, so I'm trying to work through a rather older, but helpful nonetheless book entitled "Head Rush Ajax".

I'm only finishing up the first chapter...lol and my code is not doing what its supposed to be doing. I'm sure its something simple like a typo, but I have been over it several times and cant spot the problem.

When I try to run the script in IE8, it throws an error saying object expected. line 43 code 0

Here is my complete script. According to the book I should be able to click the button and the values will update only once.

PHP Code:
var request = null;

   function createRequest() {
     try {
       request = new XMLHttpRequest();
     } catch (trymicrosoft) {
       try {
         request = new ActiveXObject("Msxml2.XMLHTTP");
       } catch (othermicrosoft) {
         try {
           request = new ActiveXObject("Microsoft.XMLHTTP");
         } catch (failed) {
           request = null;
         }
       }
     }

     if (request == null)
       alert("Error creating request object!");
   }

  function getBoardsSold() {
      createRequest();
      var url="getUpdatedBoardSales-ajax.php";
      request.open("GET", url, true);
      request.onreadystatechange = updatePage;
      request.send(null);
  }

  function updatePage()  {
   if (request.readyState == 4) {
    var newTotal = request.responseText;
    var boardsSoldEl = document.getElementById("boards-sold");
    var cashEl =   document.getElementById("cash");
    replaceText(boardsSoldEl, newTotal);

    // Figure out how much cash katie has made
    var priceEl = document.getElementById("price");
    var price = getText(priceEl);
    var costEl = document.getElementById("cost");
    var cost = getText(costEl);
    var cashPerBoard = price - cost;
    var cash = cashPerBoard * newTotal;

    //update the cash for the slopes on the form
    cash = Math.round(cash * 100) / 100;
    replaceText(cashEl, cash);
  }
}

Thanks for any help in advance!

Hi, so I have this function:

Code:

 function centerZoom() {
 var bounds = new google.maps.LatLngBounds(); 
for (var i = 0; i < gmarkers.length; i++) {
    if (!gmarkers[i].isHidden()) {
      var point = gmarkers[i].getPoint();
      bounds.extend(point);
    }
 map.setZoom(map.getBoundsZoomLevel(bounds));
        map.setCenter(bounds.getCenter()); 
		 } 
	}

which I call he

Code:

for (var j = 0; j < gmarkers.length; j++) 
    {
	
	var str=gmarkers[j].myname.toLowerCase();
	var patt1=inp;
        if (str.match(patt1)) 
        {
            found = true;
gmarkers[j].show();
	centerZoom();
}

which I thought was pretty straightforward, but I keep getting a "centerZoom is undefined" message. The only place I don't get that is if I take it out of the initialize sequence, but it doesn't work then anyway (and from what I understand, being that it contains var bounds = new... it has to go in initialize.

Here's the rest of the page, if anybody has any ideas

Function Returns Undefined

Suppose we have following javascript codes: Case 1.

var foo = function ()
{
var x = "hello";
var bar = function () {
alert(x);

}
return bar;
}

var bar_ref= foo();

document.write(bar_ref()); // it pops up "hello" and print-outs "undefined".

If we modified above code slightly, shown as follow: Case 2.
var foo = function ()
{
var x = "hello";
var bar = function () {
alert(x);

}
return bar();
}

var bar_ref= foo();

document.write(bar_ref()); // it only pops up "hello".

As you can see, Case 2 modified the return value from "return bar" to "return bar()," which won't cause the "undefined" output. To me, it looks like when the JS interpreter executes the line "bar_ref();" it triggers the execution of function "foo", besides both "return bar" and "return bar()" do the same job which is to execute function body of "bar". The only difference is that after the execution of function bar, its function body does not exist anymore, so when the interpreter executes the line "return bar;" it follows the function identifier "bar" and ends up with "undefined". This is why the Case 1 gives us "undefined", but I am not quite clear about why the Case 2 can trace down to the function body of "bar". Do you have any ideas about such difference outputs?

Onclick Event - Function Becomes Undefined

The following coding works in Konqueror 3.5.10 on Ubuntu 8.04.3 LTS but not on Firefox 3.0.10 Linux/3.5.7 XP, Opera 10.10 Linux or IE8 XP.

I can't see why but it may be to do with the recursion (showtable calls onclick calls addit which calls showtable ...). Somehow it is not seeing the addit routine the second time round.

It is meant just to add a line. Eventually it needs to be a complex table but this is for illustration. There are other ways to solve this but this would be the simplest - if it worked!

What happens is that one line is added OK but then it chokes. This is what makes me think it is the recursion but I can't see otherwise how to make it write the updated text. I realise I should have a document.close() in it as well and I have tried adding <![CDATA[ ... ]]> as well.

Other than in Konqueror, it gives an error message saying object not found (in IE8) or more explicitly:

Code:

function onclick(event){
    addit(4);
}

with 'addit is not defined' in Firebug.

In Konqueror it works sweetly.

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns='http://www.w3.org/1999/xhtml' xml:lang='en' lang='en'>
<head>
<script language='Javascript' type='text/javascript'>
if(typeof(sections) == 'undefined'){
    var sections=['Text 0','Text 1','Text 2'];
}
function addit(ilocal){
    sections.splice(sections.length,0,'Text '+ilocal);
    showtable();
 }
function showtable(){
    var i,j,ip1;
    for(i=0;i<sections.length;i++){
        ip1=i+1;
        document.write('Section ',i,':  ',sections[i],'<br>');
    }
    document.write("<input type='button' value='Add' onClick='addit(",ip1,")' /><br>");
    for(j=0;j<sections.length;j++){document.write(sections[j]," ");}
}

Cannot Set Property 'value' Of Undefined (anonymous Function)

Hello, I'm hoping someone can help me with this.

I have 3 pages that I need to put into my framework, they are products, shopping cart and billing. At the moment they work perfectly fine. Here is a live example -

http://www.cems.uwe.ac.uk/~r4-george...g/products.php

Now, I have a framework for a whole website that I need to put these pages into. (http://www.cems.uwe.ac.uk/~r4-george/wp4/index.php) The index uses a switch statement to go between pages.

Here is the index.php

PHP Code:
<?php # index.php

/*
*    This is the main page.
*    This page includes the configuration file,
*    the templates, and any content-specific modules.
*/

// Require the configuration file before any PHP code:
require_once ('./modules/config.inc.php');

// Validate what page to show:
if (isset($_GET['p'])) {
    $p = $_GET['p'];
} elseif (isset($_POST['p'])) { // Forms
    $p = $_POST['p'];
} else {
    $p = NULL;
}

// Determine what page to display:
switch ($p) {

    case 'about':
        $page = 'about.inc.php';
        $page_title = 'About This Site Again';
        break;

    case 'products':
        $page = 'products.inc.php';
        $page_title = 'Products on this site';
        break;

    case 'this':
        $page = 'this.inc.php';
        $page_title = 'This is Another Page.';
        break;

    case 'that':
        $page = 'that.inc.php';
        $page_title = 'That is Also a Page.';
        break;

    case 'contact':
        $page = 'contact.inc.php';
        $page_title = 'Contact Us';
        break;

    case 'search':
        $page = 'search.inc.php';
        $page_title = 'Search Results';
        break;

    // Default is to include the main page.
    default:
        $page = 'main.inc.php';
        $page_title = 'Site Home Page';
        break;

} // End of main switch.

// Make sure the file exists:
if (!file_exists('./modules/' . $page)) {
    $page = 'main.inc.php';
    $page_title = 'Site Home Page';
}

// Include the header file:
include_once ('./includes/header.inc');

echo "<div id=\"content\">";

// Include the content-specific module:
// $page is determined from the above switch.
include ('./modules/' . $page);

// Include the footer file to complete the template:
include_once ('./includes/footer.inc');

?>

It uses the .inc.php files located in the modules folder to switch between pages.

Here is my products.inc.php -

PHP Code:
<?
    include("includes/db.php");
    include("includes/functions.php");

    if($_REQUEST['command']=='add' && $_REQUEST['productid']>0){
        $pid=$_REQUEST['productid'];
        addtocart($pid,1);
        header("location:shoppingcart.php");
        exit();
    }
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Products</title>
<script language="javascript">
    function addtocart(pid){
        document.form1.productid.value=pid;
        document.form1.command.value='add';
        document.form1.submit();
    }
</script>
</head>

<body>
<form name="form1">
    <input type="hidden" name="productid" />
    <input type="hidden" name="command" />
</form>
<div align="center">
    <h1 align="center">Products</h1>
    <table border="0" cellpadding="2px" width="600px">
        <?
            $result=mysql_query("select * from products");
            while($row=mysql_fetch_array($result)){
        ?>
        <tr>
            <td><img src="<?=$row['picture']?>" /></td>
            <td>       <b><?=$row['name']?></b><br />
                    <?=$row['description']?><br />
                    Price:<big style="color:green">
                        £<?=$row['price']?></big><br /><br />
                    <input type="button" value="Add to Cart" onclick="addtocart(<?=$row['serial']?>)" />
            </td>
        </tr>
        <tr><td colspan="2"><hr size="1" /></td>
        <? } ?>
    </table>
</div>
</body>
</html>

This is EXACTLY the same code as the working example. The products get listed correctly but the problem I have is the 'Add to Cart' button fails to work.

Live example - http://www.cems.uwe.ac.uk/~r4-george...php?p=products

Everything is in the right directory. When I inspect the 'Add to Cart' button in chrome I get the following -

Quote:
Uncaught TypeError: Cannot set property 'value' of undefined
addtocart index.php:51
(anonymous function)index.php:83
onclick
Any help is really appreciated, I'm struggling to see what I have done wrong. I don't know whether it's a Javascript problem.

If you need any of the code from other pages I can post it too.

Thanks in advance.

var Letters = ["A", "B", "C", "D", "E", "F", "G", "H"];

// Convert the y coordinate of the piece to partial SAN (Simplified Algebraic Notation)
 for(var yCoord = 0; yCoord >  yCoord * 7; yCoord++)
    {
	 if(y == yCoord * BlockSize)
	   {
	    var SANy = Letters[yCoord];
	   }
	}
return SANy;
}

this is how i'm calling the functions:

Code:

var oldPGNx = XCoordToSAN(oldXposition);
  var oldPGNy = YCoordToSAN(oldYposition);
  var newPGNx = XCoordToSAN(newXposition);
  var newPGNy = YCoordToSAN(newYposition);
  
  NewPGNData = oldPGNx + oldPGNy + "-" + newPGNx + newPGNy + " ";
  // Finally update the Data
  document.getElementById("PGNArea").value = OldPGNData + NewPGNData;

Java Script Function Returning Undefined

I have a function where in I call another function that assigns a value to a var.

e.g.
Code:

function setVar{
   var thisVar = 'hello';
   return thisVar;
}
function callFuncSetVar {
   var newVar = setVar();
  alert(newVar);
}

For some reason my code below is returning 'undefined'. But when I place an alert(); before the 'return' it shows the correct value. However when I place an alert(); to show the var that is set to what the function returns it says 'undefined'.

Firebug throws no errors. I am using a little bit of jQuery.

Undefined Variable In Function - Scope Issue?

Similar Tutorials

View Content

Hi all,

I'm just starting out with Javascript as a development language and this will probably be a relatively simple problem for someone to solve for me.

I am trying to access a variable (this.bodyEl.innerHTML) from within a function but get an error message indicating that it is "undefined". I know that it is a valid variable because I call it elsewhere outside of the inner function itself.

I'm sure this is just a scope issue, but I'd welcome any suggestions on how to solve it with an explanation of where I've gone wrong if you have the time.

Here's the code:

Code:

    displayFeed: function(responseData) {
        this.bodyEl.innerHTML = "xxxx"; // I can see this
        var responseDoc = Presto.Util.parseXml(responseData);
        var items = Ext.DomQuery.select("/rss/channel/item", responseDoc);
        items.each(function(item, bodyHTML) {
            var rssTitle = Ext.DomQuery.selectValue("/title", item);
            var rssDescription = Ext.DomQuery.selectValue("/description", item);
            var rssLink = Ext.DomQuery.selectValue("/link", item);
            // but this results in an undefined error
            this.bodyEl.innerHTML = '<a href="' + rssLink + '">' + rssTitle + '</a><br/>';
        }); // end of items processing
    }

This is a fragment of the code from my script. The first access of "this.bodyEl.innerHTML" works fine, but the second access in the items.each loop doesn't and I get an undefined variable error.

Is this a scoping problem, and if so how is it best solved.

Thanks in advance, Innes (NZ)

"result Of Expression 'this.form.fireevent' [undefined] Is Not A Function". Help!

Hi,
My webpage can work normally in IE but not in Safari(e.g. when I clicked on some buttons like 'Delete' button, the page opened in Safari stays the same while it should delete the object chosen).

When I tried debugging on Safari, after clicking the 'update' button, this
message error appeared: "TypeError: Result of expression 'this.form.fireEvent' [undefined] is not a function". I believe this code makes the incompatability between the 2 browser:
Code:

    	    function DeleteClick()
        	{
        		var frmSWO = document.getElementById("form");
        		var answer = confirm("Do you really want to delete?")
				if (answer != 0)
				{
					frmSWO.action = "/domsWeb/mtd/doms/web/operation/eDepotMNR/controller/manageWorkOrder/DeleteJobOrImage.do";
        			frmSWO.method = "post";
        			this.form.fireEvent('onsubmit');
        			frmSWO.submit();
				}   		
        	}

Any suggest how should I amend the script for it to work on 2 browser concurrently?
Thanks all!

"is Undefined" Error When Calling Function

Similar Tutorials

Hi everyone,

I'm using a JavaScript to upload multiple files, namely this one: http://valums.com/ajax-upload/

The script has the ability to post additional parameters to the server, by calling the function setParams

Code:

			var doktyp = "default";
            var uploader = new qq.FileUploader({
                element: document.getElementById('file-uploader-scope'),
                action: 'uploads.php',
				// additional data to send, name-value pairs
				debug: true,
				onSubmit: uploader.setParams ({
						dateityp: getCheckedValue(document.forms['doktyp'].elements['dateityp']),
						comment: jQuery('#dateityp').val()
					})
				
            });

Without the onSubmit: part the script works well and does as it's supposed to, but with it FireBug reports "uploader is undefined" und the script seizes to function.
Now JavaScript istn't my strong suit, so I have been reading up on this for the last two hours, tried calling that function from a different place, tried to modify it, but no luck; the error remains the same (or slightly different; if I point at the class in question directly, the function doesnt work...).

I would appreciate any advice you could give.

Change _get Variable And Reload

From a previous search page that passes 4 form variables via $_GET to a new results.php page. On this results page, I'm building a form with many more choices to refine to refine the search results.

But I can't seem to remember the javascript to put into this form to update several $_Get variables in the url and reload the page as things are selected - so that the results are refined with each change they make.

I'm sure it was pretty simple. I just don't remember and can't seem to find something does/explains what I want.

thanks!
