JavaScript - Anonymous Function Problem

Full Excel VBA Course - Beginner to Expert

Anonymous Function Problem	View Content

What I want to do is have a two-dimension array where some of the elements point to the value in another element. I have done this successfully in PHP using referfences (=&) and now I want to do it in JavaScript. My JS skills are limited but I found this post explaining how it can be done - http://stackoverflow.com/a/1687183

Here's the code from that - Code:

Function.prototype.toString = function() {
    return this();
}

var x = 1;
var y = function() { return x }
x++;
alert(y); // prints 2

It looks like it will do what I need to do.

However, I want to use a two-dimension array, and if I try this it doesn't work - Code:

for (var a = 2; a <= 5; a++)

	for (var b = 1; b < a; b++)

		matrix[a][b] = function() { return (matrix[b][a]) };

matrix is the two-dimension array which is alreay set up with some values. The two for loops are structured to fill in the rest of the values as references to existing values (it's a 5 x 5 array).

The problem is coming from function() { return (matrix[b][a]) } because instead of the values for a and b being used in the creation of the anonymous function the actual variable names are used instead. Then later when I attempt to read one of the values setup by this it is "undefined" because the anonymous function is tries to return matrix[a][b] rather than matrix[4][2].

Can anyone help? Thanks!

Hi All, I'm trying to convert an anonymous function to a real function (nesting is getting out of hand), however the msg object becomes undefined after conversion. Here is the converted anonymous function which fails: https://gist.github.com/2587613 and here is the original anonymous function which works: https://gist.github.com/2587667

Question About Anonymous Function Declaration

I've been going through this great tutorial on how to implement a type-ahead feature on a text field and there's something which hopefully you guys can explain.

On the third page there is this function.
Code:

AutoSuggestControl.prototype.init = function () {
    var oThis = this;
    this.textbox.onkeyup = function (oEvent) {
        if (!oEvent) {
            oEvent = window.event;
        }
        oThis.handleKeyUp(oEvent);
    };
};

What I don't understand is this line: this.textbox.onkeyup = function (oEvent) {

I know about anonymous functions, but I don't know where the value for the parameter oEvent is going to come from.

Can someone explain this? Thanks! :)

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();
    }
?>

    }
</script>
</head>

            $result=mysql_query("select * from products");
            while($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.

Passing 'this' To An Anonymous Function In An Event Listener

Similar Tutorials

Hello!

I'm working with nested functions and trying to pass a 'this' value to an anonymous being used in an assignment for an event listener. Here's the basics of my code:

Code:

<div id='abc'></div>
<script type='text/javascript'>
var abc = function () {
    this.myFunction = function() {
        var myObj
        myObj = document.createElement("input");
        myObj.setAttribute("type", "button");
        myObj.setAttribute("value", "Click Me");
        myObj.addEventListener("click", function () {
            this.doDing();
        }, false);
        document.getElementById('abc').appendChild(myObj);
    }
    this.doDing = function () { alert('ding'); }
}
var myInstance = new abc();
myInstance.myFunction();
</script>

So, this should plop a button inside our DIV and when clicked I'd like it to run the alert-ding; unfortunately it seems to want to run the function as defined under the buttons object which doesn't work out too well.

Any suggestions?

Thanks!

When Closures, Loops, Function References, And Anonymous Functions Interact

Similar Tutorials

Hey all,

I am confused about the true difference between the two below examples.

Code:

first example:
// Demonstrating a problem with closures and loops
var myArray = [“Apple”, “Car”, “Tree”, “Castle”];
var closureArray = new Array();
// Loop through myArray and create a closure for each that outputs that item
for (var i = 0; i < myArray.length; i++) {
var theItem = myArray[i];
closureArray[i] = function() {
document.write(theItem + “ < br / > ”);
}
}
// Loop through the closures and execute each one.
for (var i = 0; i < closureArray.length; i++) {
closureArray[i]();
}

Here we iterate through the length of myArray, assigning the current index of myArray to theItem variable. We declare closureArray 4 times as an anonymous function. The anonymous function in turn declares the predefined write() function, which is passed parameters. Since write() is in closureArray() a closure is created??? During each iteration, theItem is reassigned its value. The four closures reference this value. Since they reference this same value and since this value is reassigned ultimately to the value of the fourth index position, tHe time we execute closureArray later on, all four closures output the same string. This is because all four closures are within the same scope "the same environment" and therefore are referencing the same local variable, which has changed.

I have a couple of problems with this example:
1) I thought a closure is a function that is returned - the inner function is not returned above.
2) theItem is not even a local variable of the parent function (closureArray) - I thought in order for a closure to work, the inner function only accesses the local variables of the outer function, but in this case the local variable is defined OUTSIDE of the parent function.
3) The guy says the "the four closures are sharing the same environment." The thing is even in the second example, they are sharing the same environment.

Second example:
Code:

// A correct use of closures within loops
var myArray = [“Apple”, “Car”, “Tree”, “Castle”];
var closureArray = new Array();
function writeItem(word) {
return function() {
document.write(word + “ < br / > ”);
}
}
// Loop through myArray and create a closure for each that outputs that item
for (var i = 0; i < myArray.length; i++) {
var theItem = myArray[i];
closureArray[i] = writeItem(theItem);
}
// Loop through the closures and execute each one.
for (var i = 0; i < closureArray.length; i++) {
closureArray[i]();
}

Here we iterate over the length of myArray (4 times), assigning the index of myArray to theItem variable. We also return a function reference to the closureArray during each iteration (closureArray[i]), where i is index number so we assign 4 functon references. So when we iterate through myArray, we immediatelly call the writeItem() fucntion passing an argument of theItem at its current value. This returns a child anonymous function and when that child function is called, it will execute a block that calls the predefined write() method. We assign that returned anonymous function to the variable closureArray. Hence, closureArray holds a reference to that anonymous function. So closureArray during each iteration holds a reference to the anonymous function and we later call closureArray, which in turn calls the anonymous function, therefore calling the predefined write() function to output the local variable of the parent function. This outputs each distinct index of myArray.
QUESTION:
This is because since we created the closure, when we call writeItem, passing theItem argument, since theItem is a local variable of the parent function of the closure, it is never destroyed when we later call closureArray (the reference to the child anonymous function)? Yet weren't we using a closure in the first example as well? So whey wasn't those variables preserved?

I don't think it has anything to do with assigning a returned anonymous function to closureArray. Even though an anonymous function creates a new memory position in the javascript engine, therefore not overwriting the other function references we create during the iteration, it's still referring to a local variable declared outside the reference. So if it's about the closure retaining value of parent's local variable even after exiting the parent function allowing for the current indexes to be preserved, then why did the closure in the first example fail to retain each index?

Thanks for response

Js Function Problem

Hi,

In ASP.NET intranet web page have user input. Have 5 check boxes with two attending text boxes for each. The default value for the text boxes is zero and the text boxes are disabled for input. When the user checks a check box the two corresponding text boxes become enabled for input.
Have two command buttons - Submit for database posting and Cancel. I set the Cancel button with a js window.confirm, uncheck the check boxes, and reset any input values in the text boxes back to zero. When I tested the code the checked check boxes were unchecked and the first text box holding user input was reset to zero value. However, the other text boxes containing user input values were not reset to zero. I altered the sequence of the code - for example - list the check box then its text boxes and so on. I tried listing the text boxes first then the check boxes. These did not resolve the problem - I was thinking linear execution of the code.
Any suggestions to rememdy this?

This is the js function:
function Empty()
{
var res=window.confirm("Please confirm cancellation-your input will be cleared");
if(res==true)
{
document.getElementById("chkDVTT").value="";
document.getElementById("chkLM").value="";
document.getElementById("chkVMB").value="";
document.getElementById("chkVEB").value="";
document.getElementById("chkVUB").value="";

    <img src="{$images_dir}/icons/icon_reload.png" height="25" width="25" alt="Reload Captcha Image" onclick="reloadCaptcha();" class="valign image-captcha" /></p>
{/if}

now the following works totally fine, when you click the captcha code changes..... "onclick="this.src += 'reload'" you will notice i have added a custom reload button image below this with a onclick calling a custom function "reloadCaptcha(); which i want to reload the captcha image above it - however it is not working, i have done the function so it grabs the src from the element ID, i have added 2 ID's to the IMG but cannot remember if you can have multiple IDs or not which if not could be causing the problem but not 100% sure how to include the smarty code for the generated ID on that image.

Any ideas on the code above from having a quick glimps? as the code stands i get the error:

Error: captureURL is null

Many Thanks

Js Simple Function Problem?

Hello I would like to know how this is not functional. surely passing the function to another function would work so I can use the same variables without having to write it out again.

<script>
function addNumbers ()
{
var firstnumber = document.calculator.myFirstNumber.value;

var total = parseInt(firstnumber) + parseInt(secondnumber);
document.calculator.myTotal.value = total;
document.calculator.myHex.value = total.toString(16);
document.calculator.myOct.value = total.toString(8);
document.calculator.myBinary.value = total.toString(2);

document.write("End of Calculation.");
}

function subtractNumbers (addNumbers)

var total = parseInt(firstnumber) - parseInt(secondnumber);

Problem With Function Parameter

Similar Tutorials

Hi,
I am learning javascript from a book ("Javascript and JQuery Missing Manual") and one example there sets my head spinning and I can't understand how the script works. I'd be very grateful if someone could write a few words about the aspect I don't understand.

Basically it is line seven I don't understand. How is the word question tied to the items in the questions array. I understand the 0 and 1 on line eight and nine and why they focus on the first and second item in the sub-array, but still, how can the word question point to the relevant item in the questions array?

Code:

var score = 0;
var questions = [
 ['How many moons does Earth have?', 1],
 ['How many moons does Saturn have?', 31],
 ['How many moons does Venus have?', 0]
];
function askQuestion(question) {
 var answer = prompt(question[0], '');
	if (answer == question[1]) {
alert('Correct!');
score++;
} else {
alert('Sorry. The correct answer is ' + question[1]);
}
	}
for (i=0; i<questions.length; i++) {
	askQuestion(questions[i]);
	}

Calling A Function Problem

Similar Tutorials

Hi.

Firstly, i apologise for this being a google maps related question but the problem is a regular javascript question i believe, and it's really frustrating me.

As i'm sure you're aware that with the maps you can click on a red 'marker' and make an info box pop up. I'm trying to do this with a text link outside of the map. My problem is calling that script via the text link. i really can't see what i'm doing wrong;

my html link
Code:

<a href="javascript;" onmouseover="marker.openInfoWindowHtml();">test</a>

and the javascript from the map
Code:

GEvent.addListener(marker, "click", function() {
marker.openInfoWindowHtml();
});

I'm sure it's something simple but i've been trying variations for hours and I can't get my head around it. Anyone with any ideas would be an absolute star.

Cheers,
Pat.
