JavaScript - My Event Won't Register Or Perform Its Task

never mind

is it possible to capture the control.event or element.event that was fired to invoke the onbeforeunload event.

for example, if a button is clicked and it causes the onbeforeunload event to fire can i determine which button was clicked.

thanks

This is urgent needs to be done by sunday.




Table must be generated dynamically, depending on the number of columns and rows that the user enters.
Table is filled with numbers, starting from the bottom-right corner, and then sequentially in a circle, in
clockwise, until all fields are filled.

Note: technology that is certified as HTML, CSS, JavaScript, jQuery, AngularJS.
The interface should be crossbrowser compatible (IE8 +, Chrome, Firefox, Opera, Safari). When should
be optimized and user interface tidy and generally correspond to the sketch.

Wth 234 posts you should know very well that this forum is not a free coding service. As a general rule, the people helping out in this forum don't write code for others (especially code that appears to be for homework), but try to help with fixing code that doesn't work. You may perhaps get someone to write this script for you, but you'll be far more likely to get help if you have made a substantial effort and written some code yourself. Then someone here will almost certainly help you correct/improve your work.

Why have you left starting your assignment so late? The outlook for your future employment appears doubtful, to say the least.

I have a ondrag event handler and in that I am trying to retrieve e.ClientX but it always return 0 in Mozilla. Works fine in IE though.

How can retrieve the clientX and clientY in ondrag event?

will make another thread with simpler explanation.

Hello fellow scriptwriters,

Is it possible to use JavaScript cookies to function the same way as for registering for a site or logging in to a members' area? And if (or not)so, what are some things to help me get started? I'd like to know because I am planning to make an alternative to PHP and MySQL methods.
Code:

function getCookie( name ) {
  var start = document.cookie.indexOf( name + "=" );
  var len = start + name.length + 1;
  if ( ( !start ) && ( name != document.cookie.substring( 0, name.length ) ) ) {
    return null;
  }
  if ( start == -1 ) return null;
  var end = document.cookie.indexOf( ";", len );
  if ( end == -1 ) end = document.cookie.length;
  return unescape( document.cookie.substring( len, end ) );
}

function setCookie( name, value, expires, path, domain, secure ) {
  var today = new Date();
  today.setTime( today.getTime() );
  if ( expires ) {
    expires = expires * 1000 * 60 * 60 * 24;
  }
  var expires_date = new Date( today.getTime() + (expires) );
  document.cookie = name+"="+escape( value ) +
    ( ( expires ) ? ";expires="+expires_date.toGMTString() : "" ) + //expires.toGMTString()
    ( ( path ) ? ";path=" + path : "" ) +
    ( ( domain ) ? ";domain=" + domain : "" ) +
    ( ( secure ) ? ";secure" : "" );
}

function deleteCookie( name, path, domain ) {
  if ( getCookie( name ) ) document.cookie = name + "=" +
    ( ( path ) ? ";path=" + path : "") +
    ( ( domain ) ? ";domain=" + domain : "" ) +
    ";expires=Thu, 01-Jan-1970 00:00:01 GMT";
}

I am 98% done with the Codecademy JS curriculum but I am stuck on this program. Can anyone see the problem?

Code:

var cashRegister = {
    total:0,
    //Dont forget to add your property
    lastTransactionAmount: 0;
    add: function(itemCost) {
        this.total +=  itemCost;
        this.lastTransactionAmount = itemCost;
    },
    scan: function(item,quantity) {
        switch (item) {
        case "eggs": this.add(0.98 * quantity); break;
        case "milk": this.add(1.23 * quantity); break;
        case "magazine": this.add(4.99 * quantity); break;
        case "chocolate": this.add(0.45 * quantity); break;
        }
        return true;
    },
    //Add the voidLastTransaction Method here
    voidLastTransaction: function(){
        this.total -= this.lastTransactionAmount;
    },
    
};

cashRegister.scan('eggs',1);
cashRegister.scan('milk',1);
cashRegister.scan('magazine',1);
cashRegister.scan('chocolate',4);

//Void the last transaction and then add 3 instead
cashRegister.voidLastTransaction();
cashRegister.scan('chocolate',3);

//Show the total bill
console.log('Your bill is '+cashRegister.total);

Hi all,

I am rather stuck with the following code and am finding it tough to find resources to help me. I am new to DOM functions and any explanation would be much appreciated!

Code:

var DATE =

{date:
         xxx, layers:
{top:
         'topLayer'
},
ids: [xxx], go: function() {}
};

I also need to add a function to the variable 'DATE' so that it can register DOM events, then modify 'DATE' so that it adds another name-value pair to layers on page.

I have been trying to working this out for 24 hours now and am very confused. Any support would be awesome!

Thank you!

Hello All,

How can i want to capture onscroll event in Javascript ?

Thanks in advance.

Hi,

New to javascript. Doing web page with ASP/VB.NET. Have text boxes for UI on page. Two command buttons - Submit (for db update) and Cancel. I need the Cancel button to prompt the user to verify cancellation. Need OK/Cancel buttons on alert. If user selects Cancel-no action. If user selects OK then I want the text boxes cleared of user text input and focus returned to first text box. I think this may be the code but do not know how to apply it.

function Clear()
{
var res=window.confirm("Please confirm cancellation-text boxes will be cleared");
if(res==true)
{
document.getElementById("StrtDte").value="";
document.getElementById("EndDte").value="";
document.getElementById("txtProjRegHrsAl").value="";
document.getElementById("txtProjOTHrsAl").value="";
document.getElementById("ddlRAS").focus();
}
}

Is this code valid or invalid for the events I need? How do I set it to fire when user clicks the ASP Cancel button?

Thanks,

John

I have a asp:textbox where I'd like to capture when the user hits Enter, and then instead of doing whatever it normally would, then it should call a javascript function. I'm not sure how to do that, other than I suppose I should use the OnTextChanged event. But I'm not sure which parameters are sent with the event...

Thanks in advance

Hi Chaps,
I have a PHP form with one input and a button. A jQuery script ('loading' animated gif) is triggered on the click of the submit button.
I also have a Spry Validation field linked to the input.
At the moment, if the validation is triggered, the animated gif continues and won't stop. The furthest I've managed to get with it, is to click the validation message to stop the animation, but what I'm really after is to stop the animation when the validation is visible/triggered, but I can't find a suitable Event.
Code:

<script type="text/javascript">
			$(function() {

				$("#button_download")
					.click(function() {
					})
					.throbber();

				$("#sprytextfield1")
					.click(function(sprytextfield1) {
						$.throbberHide();
					})
			});
</script>

If someone can point me in the right direction, that would be sweet.

Hello forum,
My name is juan and recently started html programming. I have a web page with a drop box with the name of states.
Code:

<option value="">Alabama</option>
<option value="">Alaska</option>

I can add a onclick="code here" to the tag so that when the drop box alabama is selected it triggers the onclick event.

Im using Ibox in order to have a image of the state open.

Code:

<a href="images/large/image_1b.jpg"  rel="ibox" title="alabama at 1024x450!"><img 
src="images/small/image_1.jpg" alt=""/></a>

the above is a <a> link tag correct? How do I go bout adding the above code into the onclick event?

Hi
I'm a newbie. Please help me. I'm using Joomla. I've got a dropdown which reads the filename from the database. When the user selects it I want an onchange event to open the pdf. I've been at it for 2 days now.

Code:

<?php
$con = mysql_connect('localhost', 'root', '');
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("metnet", $con);
$sql="SELECT * FROM newsletter";
$result = mysql_query($sql);
echo "<form method='post'>";
$dropdown = "<select name='sname' onChange='location(this.form.sname)' >";
while($row = mysql_fetch_assoc($result)) {
$dropdown .= "\r\n<option value='{$row['fpath']}'>{$row['fpath']}</option>";
}
$dropdown .= "\r\n</select>";
echo $dropdown;
?>

I'm trying to assign and event to a tag during the onload function,
but I don't seem to be using the correct syntax.

Can someone tell me the correct way to make the assignment?

Code:

<!DOC HTML>
<html>
<head>
<title> Test Event Assignment </title>

<script type="text/javascript">

var eMessages = ['Main 1','Main 2','Main 3'];
function eMsg(msg) { alert(msg); }

window.onload = function() {
  var sel = document.getElementById('mmenu').getElementsByTagName('dt');
  for (var i=0; i<sel.length; i++) {
//    sel[i].onclick="eMsg(eMessages[i])";          // does not work
//    sel[i].onclick="eMsg('"+eMessages[i]+"')";    // does not work
    sel[i].onclick=eMsg(eMessages[i]);              // works, but only one time on-load
  }
}
</script>

<style type="text/css">
dt { border:1px solid black; background-Color:yellow; width:50px; }
</style>

</head>
<body>
<dl id="mmenu">
 <dt> A </dt>
 <dt> B </dt>
 <dt> C </dt>
</dl>
</body>
</html>

Ultimately I would like it to do something more useful than an alert,
but approaching the problem one piece at a time.
