Javascript onClick event in all cells

Javascript onClick event in all cells

I'm learning JavaScript and I've not that much experience. But I'm making
a HTML table and I want to add in every table cell (<td>) a onClick event.
<table id="1">
<tr>
<td onClick="tes()">1</td><td onClick="tes()">2</td>
</tr>
<tr>
<td onClick="tes()">3</td><td onClick="tes()">4</td>
</tr>
</table>
Is there another way to do this event in every cell?

Oh no. Upgrade interupted. Please help

Oh no. Upgrade interupted. Please help

I have decided to upgrade my Ubuntu 12.04 to 12.10. I had about 4.1GB
space left on /. NOt until the last minute during the install phase did
the upgrade manager ask me to make space on my drive. I started the
software manager and now I can't get out of it back to continuing the
upgrade. It keeps on asking me to repair the package catalogue, and has no
x bar or button to close it, nor can I alt-tab to the updater window. I am
stuck half way through an upgrade and can't get out. I have been a fan of
ubuntu for years but after today I fear I have lost confidence.... Please
someone help. How can they write software that allows this to happen.
Should they be making sure there is adequate disk space before the
upgrade.

Rollover to be loaded with the index page and disappears when iframe is loaded with content from a link

Rollover to be loaded with the index page and disappears when iframe is
loaded with content from a link

I'm having a small issue with iframe and rollover image.
What I want to achieve is when I load this index site it should display a
rollover image(or a slider later on once I know how to do it) in the
middle of the page. I have placed an iframe in the middle of this index
page. This iframe is going to be the target of the horizontal menubar...
How do I make them to co-exist, rollover to be loaded by default and
disappears once the iframe is loaded with content from a link?
I have tried to place a rollover inside the iframe and also now inside the
same div of the iframeBut the result is not good since the rollover image
is not disappearing when loading a link to the iframe:
<div><center>

TableView not showing

TableView not showing

I have a very big FXML file that I designed on JavaFx SceneBuilder. When I
try adding a TableView now, the TableView only shows in the JavaFx
SceneBuilder and SceneBuilder's "Preview in Window", but not when I run
the project from netbeans.
Everything else in the scene shows perfectly.
Has anyone ever experienced this problem during development? How do I make
the TableView show when I run the project?
Thank you all in advance.

Slider Puzzle problems

Slider Puzzle problems

This is my slider puzzle game. So far it can only do 3x3 games. When I try
and pass the variables l and w (length and width) of the board it doesn't
work. It only works when i set the variables ROWS and COLS as finals. When
I try and change it I get errors. I'm not sure what to do, any help would
be appreciated.
Currently the user can input values that can't do anything at the moment.
When the game is started, a 3x3 board is generated. The user can restart
the game with a different scrambled board but the buttons that solve the
board and the buttons that reset the board to the original state do not
work yet.
public class SlidePuzzle {

Wait for the end of an asynchronous Javascript function to retrieve a result (Deferred ?)

Wait for the end of an asynchronous Javascript function to retrieve a
result (Deferred ?)

Ok guys, I know this topic has already been discussed multiple times, but
I can't find an answer to solve my problem.

So I'm trying to do a simple think : I'm creating a string, like :
distance is : " + CalculateDistance(position); The wanted result is
something like distance is 5kms (8min).
CalculateDistance(position) is a function calling a Google maps API called
DistanceMatrix to calculate distance between two points. The API is
documented here, and the given sample perfectly works. I adapted it like
this :
function CalculateDistance(position)
{
var service = new google.maps.DistanceMatrixService();
var destination = new google.maps.LatLng(/* some lat/lng */);
service.getDistanceMatrix(
{
origins: [position],
destinations: [destination],
travelMode: google.maps.TravelMode.DRIVING,
unitSystem: google.maps.UnitSystem.METRIC,
avoidHighways: false,
avoidTolls: false
}, callback);
}
function callback(response, status) {
if (status == google.maps.DistanceMatrixStatus.OK)
{
var origins = response.originAddresses;
var destinations = response.destinationAddresses;
var results = response.rows[0].elements;
distanceMatrixResult = results[0].distance.text + " ( " +
results[0].duration.text + " min)";
}
Oh, by the way, distanceMatrixResult is a global variable. In fact, I just
need to get the content of results[0].distance.text (and when I print it
in the console in callback(), the value is OK) and then concatenate the
value with "Distance is". If someone have a smarter solution, it is
welcomed !
The API call is asynchronous, and in my case, distanceMatrixResult is
always empty in the result string. But when I log its value in the
console, distanceMatrixResult value became the good one AFTER the string
was created.
All I want to write is :
• Call CalculateDistance (which call callback asynchronously)
• When callback is ended, concatenate the string with the
distanceMatrixResult value.
I tried some Deferred, like $.done() and $.when().then() but I can't
success...
Can someone help me ?
Thank you !
