What I initially wanted to do is this:
if (myTargetName == 'a') {
var myOtherTargetName:String = "b";
var myOtherTarget:DisplayObject = getChildByName(myOtherTargetName);
}
if (myTargetName == 'c') {
var myOtherTargetName:String = "d";
var myOtherTarget:DisplayObject = getChildByName(myOtherTargetName);
}
as you can see, I get a 'Duplicate variable definition' error since im declaring the variables twice. My solution I thought would be to just declare those variables outside the if statements, and change the variable inside the statement, like so:
var myOtherTargetName:String = ""
var myOtherTarget:DisplayObject = None;
if (myTargetName == 'a') {
myOtherTargetName = "b";
myOtherTarget = getChildByName(myOtherTargetName);
}
if (myTargetName == 'c') {
myOtherTargetName = "d";
myOtherTarget = getChildByName(myOtherTargetName);
}
This gives an error saying "access of undefined property None". Now, I don't want to set
myOtherTarget:DisplayObject
to an actual existing display object which is on the stage just yet, I want to set it to an object on the stage inside the if statements. Is there a way to set
myOtherTarget:DisplayObject
to nothing?
It is easy, copy+paste it:
var myOtherTarget:DisplayObject = null;
or simply:
var myOtherTarget:DisplayObject;

I have an input textfield named "textbox" and a button named "submit".I also have two text messages "mc_error" and "form_submitted" which are not visible from the beginning. Upon clicking the button, I want it to check if the textfield contains "#" in it. I have tried the below code that uses indexOf but it always returns the value -1 and therefore upon execution always "mc_error" becomes visible.
var str:String = textbox.text;
submit.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler);
mc_error.visible = false;
form_submitted.visible = false;
function fl_MouseClickHandler(event:MouseEvent):void
{
var index:int = str.indexOf("#");
if(index == -1)
{
mc_error.visible=true;
}
else
{
form_submitted.visible=true;
}
}
Would be grateful if got some immediate answers as i need it working in 2 days.Thanks
Because you set variable before user inputs anything there and it is always "". Just don't use that variable (or read it in the function body as shown below) and it will be fine.
function fl_MouseClickHandler(event:MouseEvent):void
{
var str:String = textbox.text;
var index:int = str.indexOf("#");
if(index == -1)
{
mc_error.visible=true;
}
else
{
form_submitted.visible=true;
}
}
Serge's solution here seemed like the way to go about this, but I'm a bit afraid that my circumstances may be too different...
I have a button where users can add a new set of rows with controls to a FlexTable, in order to allow them to insert a new member into a record set. After designing and building the app to do this (and despite assurances to the contrary), a requirement was then added for the users to be able to edit the record sets at a later date.
I've finally managed to get the data retrieved and correctly displayed on the Ui - for single member record sets. As a final stage, I am now attempting to extend this to accommodate record sets having more than one member. Obviously this requires determining how many members there are in the record set, and then adding the new rows/control group to the FlexTable, before loading the member into each control group.
So within this routine, (depending on how many members there are) I may need to trigger the same callback, which the user normally does with a button. However, the difference with Serge's fine example, is that his code triggers the checkbox callback at the end of his routine once all the Ui components are in place. My situation needs to do this on the fly - and so far I'm getting 'Unexpected error', which suggests to me that the Ui is not able to update with the added FlexTable controls before my code attempts to assign values to them.
Does anyone have any insight into this problem? Is my only recourse to completely re-build a fixed Ui and dispense with the dynamic rowset model?
Code follows -
1. event for adding controls:
var app = UiApp.getActiveApplication();
var oFlexGrid = app.getElementById('ExpenseDetail');
var oRowCount = app.getElementById('rowCount');
var oScriptDBId = app.getElementById('scriptDBId');
var iRows = parseInt(e.parameter.rowCount);
var sVId = e.parameter.scriptDBId;
var vGridDefs = loadArrayById(sVId); //retrieve upload definition array from ScriptDB
var vControlNames = [];
if (isOdd(iRows)){
var sColour = 'AliceBlue';
} else {
var sColour = 'LavenderBlush';
};
oFlexGrid.insertRow(0);
oFlexGrid.insertRow(0);
oFlexGrid.insertRow(0);
oFlexGrid.insertRow(0);
oFlexGrid.setRowStyleAttributes(0,{'backgroundColor':sColour});
oFlexGrid.setRowStyleAttributes(1,{'backgroundColor':sColour});
oFlexGrid.setRowStyleAttributes(2,{'backgroundColor':sColour});
oFlexGrid.setRowStyleAttributes(3,{'backgroundColor':sColour});
var vExpenseDef = Get_NamedRangeValues_(CONST_SSKEY_APP,'UIAPP_GridExpense');
iRows = iRows+1;
vControlNames = CreateGrid_MixedSet_(iRows, vExpenseDef, oFlexGrid, app);
oRowCount.setText(iRows.toString()).setValue(iRows.toString());
//SOME INCONSEQUENTIAL CODE REMOVED HERE, LET ME KNOW IF YOU NEED IT
vGridDefs = vGridDefs.concat(vControlNames); // unify grid definition arrays
var sAryId = saveArray('expenseFieldDef', vGridDefs);
oScriptDBId.setText(sAryId).setValue(sAryId); //store array and save ScriptDB ID
if (e.parameter.source == 'btnExpenseAdd'){
hideDialog(); //IGNORE CHEKCBOX-DRIVEN CALLS
};
return app;
2. routine that calls the event
var app = UiApp.getActiveApplication();
var oPanelExpense = app.getElementById('mainPanelExpense');
var oPanelIncome = app.getElementById('mainPanelIncome');
var oPanelEdit = app.getElementById('mainPanelEdit');
var chkExpenseAdd= app.getElementById('chkExpenseAdd');
var bExpenseTrigger = e.parameter.chkExpenseAdd;
var sVoucherId = nnGenericFuncLib.cacheLoadObject(CACHE_EDIT_VOUCHERID);
var sVoucher = e.parameter.ListSearch1Vouchers;
var aryVoucherInfo = getVoucherEditDetail(sVoucherId);
//SAVE FOR RECORD MARKING CALLBACK
nnGenericFuncLib.cacheSaveObject(CACHE_EDIT_OLDRECORDS, JSON.stringify(aryVoucherInfo), CACHE_TIMEOUT);
sVoucher = nnGenericFuncLib.textPad(sVoucher, '0', 7);
var bExp = (sVoucher.substring(0,2) == '03')
var oRowCount = app.getElementById('rowCount');
var iRowCount = parseInt(e.parameter.rowCount);
var sControlName = '';
var vControlVal = '';
var iExpIdx = 0;
var sControlType = '';
var oControl = '';
var vSummaryTotal = 0;
for (var iVal in aryVoucherInfo){
sControlName = aryVoucherInfo[iVal][2];
vControlVal = aryVoucherInfo[iVal][3];
switch (sControlName){
case 'ESUM60':
vSummaryTotal = vControlVal;
break;
case 'EXUSRN':
continue; //DON'T OVERWRITE CURRENT USERNAME
break;
};
if (sControlName.indexOf('_')!=-1){ //TEST FOR CONTROL SET MEMBER
var aryControlSet = sControlName.split('_');
if (parseInt(aryControlSet[1])>iRowCount){//*** TRIGGER THE EVENT ***
Logger.log(bExpenseTrigger + ' - ' + !bExpenseTrigger);
chkExpenseAdd.setValue(!bExpenseTrigger, true);
iRowCount = iRowCount +1;
};
};
oControl = app.getElementById(sControlName);
var vCache = cacheSaveReturn(CACHE_UIEX_LISTS,sControlName);
if (typeof vCache == 'undefined'){
oControl.setValue(vControlVal);
oControl.setText(vControlVal);
//controlSetTextBox(oControl,vControlVal);
//controlSetDateBox(oControl,vControlVal);
} else {
if (!(nnGenericFuncLib.arrayIsReal(vCache))){
vCache = JSON.parse(vCache);
};
vCache = vCache.indexOf(vControlVal);
if (vCache != -1){
oControl.setSelectedIndex(vCache);
} else {
controlSetListBox(oControl,vControlVal);
};
};
};
//SOME CODE REMOVED HERE
hideDialog();
return app;
Mogsdad to the rescue!
The answer (see above) for those at the back of the class (with me) is to simply pass the app instance parameter (e) to the event function, calling it directly from the main routine, thus keeping the chronology in step for when it returns the app to complete the routine. No need for the checkbox in this situation.
This only took me all day, but thanks Mogsdad! :)
Snippet below taken from 1/2 way down code sample 2 in the OP:
if (sControlName.indexOf('_')!=-1){ //TEST FOR CONTROL SET MEMBER
var aryControlSet = sControlName.split('_');
if (parseInt(aryControlSet[1])>iRowCount){
eventAddExpense(e); //THAT'S ALL IT TAKES
iRowCount = iRowCount +1;
};
};
I have twenty eight instances of a two-frame MovieClip (frame1 = off - frame 2 = on) to select PDFs to send. The following code works fine, but I am looking to tighten it up and make it less verbose and easier to read. I include only one reference to an instance for space and sanity sake.
function PDFClick(e:MouseEvent):void {
targetPDF = e.target.ID;
trace("targetPDF " +targetPDF);
if (targetPDF == "PDF1")
if (pdf.pcconnectionPDF1.currentFrame == 1)
{
pdf.pcconnectionPDF1.gotoAndPlay(2);
PDF1 = 1;
trace("PDF1 is "+PDF1);
}else{
pdf.pcconnectionPDF1.gotoAndPlay(1);
PDF1 = 0;
trace("PDF1 is "+PDF1);
}
Thanks! trying to learn
You'll want to generalize your calls to your ID, that way you don't need special code for each condition.
function PDFClick(e:MouseEvent):void {
var ID:String = e.target.ID;
var mc = pdf["pcconnection" + ID];
if (mc.currentframe == 1) {
mc.gotoAndPlay(2);
this[ID] = 1;
} else {
mc.gotoAndPlay(1);
this[ID] = 0;
}
}
How about this:
function PDFClick(e:MouseEvent):void {
targetPDF = e.target.ID;
trace("targetPDF " +targetPDF);
if (targetPDF == "PDF1") {
var frame:int = pdf.pconnectionPDF1.currentFrame;
pdf.pconnectionPDF1.gotoAndPlay( frame == 1 ? (PDF1 = 1)+1 : (PDF1 = 0)+1 );
}
}
I think that's about what you are looking for.
I'm tying to pass the contents of
B1L_bnt.text
to
buddy_txt.text
Can anyone tell me what am doing Wong here?
function clickHandler(event:MouseEvent):void
{
/*container_mcM.removeEventListener(MouseEvent.CLICK,clickHandler);*/
var clickedObject:DisplayObject = event.target as DisplayObject;
var bobby = Object(root).littlepicker.B1L_bnt.text;
if (clickedObject.name == 'frd_bnt1')
{
Object(root).BFFwho.buddy_txt.text = "bobby";
Object(root).gotoAndPlay(15);
}
Try this:
function clickHandler(event:MouseEvent):void
{
/*container_mcM.removeEventListener(MouseEvent.CLICK,clickHandler);*/
var clickedObject:DisplayObject = event.target as DisplayObject;
var bobby = Object(root).littlepicker.B1L_bnt.text;
if (clickedObject.name == 'frd_bnt1')
{
Object(root).BFFwho.buddy_txt.text = bobby;
Object(root).gotoAndPlay(15);
}
The issue was that you were declaring a variable named bobby. When you were trying to set the text of buddy_txtyou were setting it to a literal String 'bobby' instead of the value of the variable.
I'll start by showing my code.
var modules:Object = new Object();
modules = DPServices.getModules.lastResult;
for each (var item:Object in modules){
if(item.menu == 0){
// Don't know what to do here!!
}
}
modulesDG.dataProvider = modules;
By the way this is ActionScript 3.
What I am trying to do is change the value from a 0 to 'No' or a 1 to 'Yes'. I have tried modules.menu = 'no', modules.item.menu = 'no', and modules.#menu = 'no'. So how do I change this value?
Is modules an object of objects? If not, this should be fine:
item.menu = 'no';
You want to change menu to 1 if it's 0?
Isn't it enough to just do:
if(item.menu == 0){
item.menu = 1;
}
Though I'm not exactly sure what you're asking for.
