Functions Layer Functions - This is what controls the whole movie. Function AddPolls(): Populates Drop Down Menu with Poll Listings and then allows A user to select from that list. function AddPolls() { for (i=0; i<NumPolls; i++) { var pollName = eval("PollName"+i); var pollID = eval("PollID"+i); PollSelect.addItem(pollName, pollID); }

Change Handler Set ChangeHandler PollSelect.setChangeHandler("SelectPoll") ; _root.Status = "Select a Poll: Please take some time to answer our survey - You can only Vote once."; }

Select Poll Function Function SelectPoll(): Tells the movie what to do when a user has selected a Poll. Then loads the corresponding data for that Poll. function SelectPoll(){ PollName = PollSelect.getSelectedItem().label; PollID = PollSelect.getSelectedItem().data; _root.Status = "Loading information for "+PollName+" "; _root.Go = ""; _root.Thinking.gotoAndPlay(2); _root.CoverChart.gotoAndStop(1); loadVariables(PathToPHP+"LoadPollData.php?PollID="+PollID, _root); }

Set Poll Function Function setPollData(): Just dynamically sets the Radio Buttons with the current selection choices from the database. function setPollData() { radioGroup.setChangeHandler("vote"); CheckBox1.setLabel(Selection1); CheckBox1.setData("Votes1"); CheckBox2.setLabel(Selection2); CheckBox2.setData("Votes2"); CheckBox3.setLabel(Selection3); CheckBox3.setData("Votes3"); CheckBox4.setLabel(Selection4); CheckBox4.setData("Votes4"); QuestionNew = Question; _root.CoverBooth.gotoAndStop(2); _root.Status = "You can now Vote for "+PollName+" Category"; voteButton.setClickHandler("voteNow"); }

Vote Now Function Function voteNow(): This is what actually sends the users choice to the database and increments the total votes for that selection by 1. function voteNow() { if (radioGroup.getValue() ne "") { _root.Go = ""; _root.Thinking.gotoAndPlay(2); _root.CoverBooth.gotoAndStop(1); Status = "Thank you for you vote - We are currently checking to see if you have already voted - and updating"; loadVariables(PathToPHP+"VoteFor.php?PollID="+PollID+"&Vote="+r adioGroup.getValue(), _root); } else { _root.Status = "Please Select a Category to vote for"; }

Select Chart Function (1) Function createChart(): This creates the Charts assigns values for the title and x and y values. function createChart() { Set Chart Titles - You can also set other properties here if you feel like it. myBarChart.setChartTitle("Results"); myPieChart.setChartTitle("Results");

Select Chart (2) Set Data Provider The Selection variables are from an earlier database query - the updated values where just returned. var pollData = new DataProviderClass(); var items = new Array({label: Selection1+"("+VotesNew1+")", value: VotesNew1}, {label: Selection2+"("+VotesNew2+")", value: VotesNew2}, {label: Selection3+"("+VotesNew3+")", value: VotesNew3}, {label: Selection4+"("+VotesNew4+")", value: VotesNew4}); for (var i = 0; i < items.length; i++) { pollData.addItem(items[i]); }

Chart Function (3) Assign Data Provider to Bar and Pie Chart. myBarChart.setDataProvider(pollData); myPieChart.setDataProvider(pollData); myBarChart.sortItemsBy("value", "DESC"); myPieChart.sortItemsBy("value", "DESC"); }
