Why my add Event listener doesn't work correctly? - easeljs

Here is my code.
var _this = this;
var i = 0;
var object;
for (i=1 ; i <5 ; i++){
object = new lib.A ();
object.x = 50 * i;
object.y = 100;
_this.addChild (object);
object.on ("tick" , position , true)
}
function position(){
object.y += 1;
}
I have an object in the library and create and add to stage 4 number.
I want to move down all object with the addEventListener (tick), but it moves last object.


You need to reference the clicked object. In your code, the object variable changes in your for-loop, so at the end it is the last known value. Instead use the clicked target from the event (passed in the click handler):
function position(event){
event.currentTarget.y += 1;
}
Cheers,


I hope you have a stage somewhere in your code to depict the canvas, as in:
stage = new createjs.Stage("gameCanvas");
I think you're missing stage.update(event) as in:
function position(event){
//....update the poositions
stage.update(event);
}

EPPlus chart(pie,barchart) selected(B2,B36,B38) .. etc excel cells

I have similar to the link below problem.
EPPlus chart from list of single excel cells. How?
I tried the code but it shows it twice in the chart. For example:
This code show excel chart -> select data-> horizontal(category) axis labels tab you show 100,100,300,600 write. What is the reason for this? The chart is written twice the first data I did not find a solution to the problem.

I think you just discovered a bug with EPPlus. Shame on me for not noticing that with that post you reference. It seems that when using the Excel union range selector (the cell names separated by commas) the iterator for the ExcelRange class returns a double reference to the first cell, in this case B2.
A work around would be to use the other overload for Series.Add which will take two string ranges. Here is a unit test that show the problem and the workaround:
[TestMethod]
public void Chart_From_Cell_Union_Selector_Bug_Test()
{
var existingFile = new FileInfo(#"c:\temp\Chart_From_Cell_Union_Selector_Bug_Test.xlsx");
if (existingFile.Exists)
existingFile.Delete();
using (var pck = new ExcelPackage(existingFile))
{
var myWorkSheet = pck.Workbook.Worksheets.Add("Content");
var ExcelWorksheet = pck.Workbook.Worksheets.Add("Chart");
//Some data
myWorkSheet.Cells["A1"].Value = "A";
myWorkSheet.Cells["A2"].Value = 100; myWorkSheet.Cells["A3"].Value = 400; myWorkSheet.Cells["A4"].Value = 200; myWorkSheet.Cells["A5"].Value = 300; myWorkSheet.Cells["A6"].Value = 600; myWorkSheet.Cells["A7"].Value = 500;
myWorkSheet.Cells["B1"].Value = "B";
myWorkSheet.Cells["B2"].Value = 300; myWorkSheet.Cells["B3"].Value = 200; myWorkSheet.Cells["B4"].Value = 1000; myWorkSheet.Cells["B5"].Value = 600; myWorkSheet.Cells["B6"].Value = 500; myWorkSheet.Cells["B7"].Value = 200;
//Pie chart shows with EXTRA B2 entry due to problem with ExcelRange Enumerator
ExcelRange values = myWorkSheet.Cells["B2,B4,B6"]; //when the iterator is evaluated it will return the first cell twice: "B2,B2,B4,B6"
ExcelRange xvalues = myWorkSheet.Cells["A2,A4,A6"]; //when the iterator is evaluated it will return the first cell twice: "A2,A2,A4,A6"
var chartBug = ExcelWorksheet.Drawings.AddChart("Chart BAD", eChartType.Pie);
chartBug.Series.Add(values, xvalues);
chartBug.Title.Text = "Using ExcelRange";
//Pie chart shows correctly when using string addresses and avoiding ExcelRange
var chartGood = ExcelWorksheet.Drawings.AddChart("Chart GOOD", eChartType.Pie);
chartGood.SetPosition(10, 0, 0, 0);
chartGood.Series.Add("Content!B2,Content!B4,Content!B6", "Content!A2,Content!A4,Content!A6");
chartGood.Title.Text = "Using String References";
pck.Save();
}
}
Here is the output:
I will post it as an issue on their codeplex page to see if they can get it fixed for the next release.

Access non static function from static function

Here is some insight: I am working with UnityScript in Unity 4.6.3. I have one script called Pause.js and it contains this function:
function fadeMusicOut () {
while (audio.volume >= 0.005) {
yield WaitForSeconds(0.1);
Debug.Log("Loop Entered: " + audio.volume);
audio.volume = (audio.volume - 0.015);
}
Another script GameManager.js has this function:
static function Score (wallName : String) {
if (wallName == "rightWall") {
playerScore01 += 1;
}
else {
playerScore02 += 1;
}
if (playerScore01 == SettingsBack.scoreLimit || playerScore02 == SettingsBack.scoreLimit)
{
startParticles = 1;
SettingsBack.gameOver = 1;
BallControl.fadeSound = 1;
yield WaitForSeconds(4);
Camera.main.SendMessage("fadeOut");
Pause.fadeMusic = 1;
SettingsBack.soundVolume = 0;
yield WaitForSeconds(2);
playerScore01 = 0;
playerScore02 = 0;
SettingsBack.soundVolume = oldSoundVol;
Application.LoadLevel("_Menu");
}
}
So pretty much I want to call the fadeMusicOut() function from static function Score, but it will not let me because it says it needs an instance of that object.
The Pause.js script is not attached to any game objects, but it is attached to 2 buttons that call their specific functions. The GameManager.js script is attached to an object called GM. So how can I go about calling fadeMusicOut() from the Score function?
I have tried setting new vars that import the game object but still no luck. I tried making fadeMusicOut() a static function, but it creates many errors.
Any help at all is appreciated.

How to call ImageView by objectName in QML

I am dynamically creating images in my QML. This is the code I am using:
for (var n = 0; n < 3 * numberOfTiles; n ++) {
var image = imageDefinition.createObject();
image.translationX = getX(n);
image.translationY = getY(n);
image.objectName = ("image"+n)
drawContainer.add(image);
}
Image creating works well, except I don't know how to call those images afterdawrds. I can't set them an ID, and I don't know if setting objectName like that works.
I don't get any errors, and if this work, how can I call "image3" from QML to move it? I don't want to use c++.

Found out a solution on my own. First I add this to have global access
property list<ImageView> images
And then I create images in array and copy them over
onCreationCompleted: {
//you need a tmp variable, since you can't do that with property variant
var imagesTmp = Array();
for (var n = 0; n < 3 * numberOfTiles; n ++) {
imagesTmp[n] = imageDefinition.createObject()
imagesTmp[n].translationX = getX(n);
imagesTmp[n].translationY = getY(n);
drawContainer.add(imagesTmp[n]);
}
images = imagesTmp;
images[3].translationX = 10; //as example, this works!
}
As it turns out images keeps reference to the image

How can i force website to stay in frame?

I'm using Firefox + searchbastard addon to do a multi-search on shopping search engines.The pages are part of a frame. This works just fine for all sites I tried so far except for shopmania.com.
If I use noscript to forbid scripts from the shopmania domain name then everything stays in place but the part of the website elements become nonresponsive. I know there is an option in Firefox to force links that open in a new window to open in a new tab. Is there something similar to prevent websites from popping out of frame? Maybe a Firefox addon that blocks these requests?
Or at least can someone please tell me what is causing only this website to act like this?
EDIT: What tool can i use to pause firefox OR javascript and stepthrough code like in c++ ? I tried a javascript debugger and firebug. They don't help but i'm probably not using them right..
EDIT2: I tried this greasemonkey script : https://userscripts.org/scripts/show/92424. It does not work so i guess it isn't because of 'target' attribute

This is wrong. I'm guessing you're using a plugin to capture and override the output some site gives you. I'm pretty sure this violates their ToS and it's not a very nice thing to do in general.
JavaScript is not designed to allow this kind of meddling. It's patchy at best.
If you want to use the data from a website, to aggregate or display in some manner, use their public API. If they don't have a public API they probably don't want you to use their service in such a manner.

The solution : I took the script from Stop execution of Javascript function (client side) or tweak it and modified it to search for the tag that has in it top.location = location and then appended a new script with the if (top != self) {top.location = location;} line commented . Being a js total newbie i don't know if it's the most elegant choice but it soves the prob. Special thanks to Tim Fountain.
I will leave this open just in case someone else will suggest a better solution, for my and others's education. Again thanks for the help.

Ext.form.Basic how to reset fields when trackResetOnLoad true?

I got a Ext.form.Basic with the trackResetOnLoad:true config.
When I call reset() on a field it gets its values from the form setValues() method.
How do I reset my fields now?
When I just do field.setValue('') the form marks it as invalid because the field is required.
Thanks in advance.

You have to manually reset all of the originValues of all fields (and some other)
This snipped will do this
var items = form.getForm().getFields().items,
i = 0,
len = items.length;
for(; i < len; i++) {
var c = items[i];
c.value = '';
if(c.mixins && c.mixins.field && typeof c.mixins.field['initValue'] == 'function'){
c.mixins.field.initValue.apply(c);
c.wasDirty = false;
}
}
working example

What works for me is to take a copy of the values just after the form is created using something like var originalValues = myForm.getFieldValues(); then I can later restore those values using myForm.setValues(originalValues); instead of calling myForm.reset(...);
