Hmmm, maybe someone can help me out here or point me in the right direction , as i have been banging my head against the wall for a number of days now and dont seem to be gettin anywhere useful.
(and admittedly i'm pretty new with regards to json,objects, google visulization etc)
essentially, i am running 3 different queries on the same page against 3 different fusion tables, which in return are supposed to return an array of 3 different xets of markers.
all is fine, when i run the queries individually and make an array of the markers .
however, running the 3 queries on the same page, i can't seem to find a way to identify the query in the response function.
any hints much appreciated. and i'll be happy to provide more info if needed (tried to get rid of some unneccessary stuff)
this is what i have. thanks
a) calling the function "setFusionData()" with all relevant vars. something like setFusionData("'LatLng','name'", 2729461);
(this is calles 3 times with different variables)
function setFusionData(selColumns,tableId) {
/****
an actual query example is this:
http://www.google.com/fusiontables/gvizdata?tqx=reqId:1234&tq="select+'LatLng','name'+from+2729461"
****/
var query = new google.visualization.Query(
'http://www.google.com/fusiontables/gvizdata?tqx=reqId:1234&tq='+ encodeURIComponent("SELECT "+selColumns+" FROM "+tableId+"")
);
query.send(getFusionData); //do something with the response
}
function getFusionData(response) {
/**
here, is the problem as i need to get the table id or reqId or anything that is uniquely passed on from "setFusionData" above
also something like
alert(JSON.stringify(response)) does not return any reqId or table id either
***/
/*return rows/columns and add values to an array of markers***/
var numRows = response.getDataTable().getNumberOfRows();
var numCols = response.getDataTable().getNumberOfColumns();
for (i = 0; i < numRows; i++) {
/* add markers to array etc this works fine***/
}
}
i also tried something like this:
function setFusionData(selColumns,tableId) {
......
query.send(getFusionData({reqId:tableId}));
}
function getFusionData(response) {
alert(response['reqId']);//returns tableId. but how do i get the tableData ?
}
with wich i can get the reqId, but not the table*Data*. So I am only able to get either id or data :(
----edit----------------
after messing around a bit more (see below) it appears that the key/value pairs that get returned when typing the query into the browser directly are different than what gets returned by the call from the script...i.e the following
http ://www.google.com/fusiontables/gvizdata?tqx=reqId:1234&tq="select+'LatLng','name'+from+2729461"
typed directly into the browser bar will return
version:'0.5',reqId:'1234',status:'ok',table etc
however, calling the same from within the script returns something like
{
"rj":"0.5","ef":"ok","pb":[],"qb":[],"h":"{"cols":
[{"id":"col2","label":"LatLng","type":"string"},{"id":"col1","label":"name","type":"string"}],
"rows":
[{"c":[{"v":"47.20572,12.70414"},
{"v":"Hohe Tauern"}]},{"c":[{"v":"47.5530395,12.925611"},{"v":"Berchtesgaden"}]},{"c":[{"v":"47.5585405,14.61887"},{"v":"Gesu00e4use"}]}],
"p":{"totalrows":3}
}"
}
, so no 'reqId' but only some cryptic keys (without one that looks like the reqId either)...... anyone any idea why that would/could be ?
Sometimes you can figure it out by just looking at the JSON response, your sample request returns:
google.visualization.Query.setResponse({
version:'0.5',
reqId:'1234',
status:'ok',
table: {
...
}
})
You already got response.reqId to identify which request is this the response for, now you can use response.table to create a new DataTable instance:
var dt = new google.visualization.DataTable(response.table);
Or, since you have multiple tables, put then in an array indexed with the reqId
tables[response.reqId] = new google.visualization.DataTable(response.table);
You'd do var tables = new Array() before calling setFusionData() for the first time.

So I have a List and I am able to filter to find on it which works fine for reducing the list to what I am looking for.
However, let's say I just want to get back an array of numbers, not a List, back from my search, something like:
var found = campaignTimelineBoardTemplatesModels.map((campaignTime) => {
if (campaignTime.getId() == num)
return Math.random();
});
The problem is that found is now still a List, and 2, is that I have a undefined members in this List as it seems to hold the same size as my original List.
So Map didn't do it.
All I am trying to do is get back a simple list of pure numbers that match a condition back as a pure array.
Is it possible?
Thanks,
Sean
found it, magic of reduce:
var IDs = campaignTimelineBoardTemplatesModels.reduce((result,campaignTimelineBoardTemplatesModel: CampaignTimelineBoardTemplatesModel)=>{
if (campaignTimelineBoardTemplatesModel.getCampaignTimelineId() == i_campaign_timeline_id)
result.push(campaignTimelineBoardTemplatesModel.getCampaignTimelineId());
return result;
},[])
Sometimes JavaScript is playing with me (although the deal was that I would be playing with it...) This test code below keeps resisting so I'm looking for a little help from more clever people around here.
Answering to a recent question I tried to create a readable list of all the color IDs useable in Google Advanced Calendar API.
The request is very simple : Calendar.Colors.get()
The response is an object with a couple of properties, each one being other objects with other properties.
I can go down to the second level but the last -and most useful in this case - level returns a disturbing "undefined" (see partial log below)
And that's my question...
code with comments :
function getColorList(){
var colors = Calendar.Colors.get();
//Logger.log(JSON.stringify(colors));
for(var cat in colors){
Logger.log("category "+cat+" = "+JSON.stringify(colors[cat])+'\n\n')
}
// from there I try the "event" category
var events = colors["event"];
Logger.log('object colors["event"] = '+ JSON.stringify(events))
// then I try to get every properties in this object
for(var val in events){
Logger.log("key "+val+" = "+JSON.stringify(events[val]))
}
}
Full log is viewable here (externalized to keep this reasonably short)
Looks like (key) may be indicating a read-only definition as Sandy was eluding to.
Just make your own object from colors to loop through after converting it to string:
var json = JSON.stringify(colors["event"]);
var myObj = JSON.parse(json);
for(var val in myObj){
Logger.log("key "+ val +" = "+JSON.stringify(myObj[val]))
}
I am trying to count the number of rows in an advanceddatagrid
I need a function which could count all item with or without filterFunction.
I tried some solution but none works. The best that I found, is to expand all items and use a cursor for looping.
But, when we have a lot of data, expanding all is not a good solution.
Do you have an idea on how to do that ?
Thank you
The only way I came up was investigating dataProvider
// current not expanded data row lenght
grid.dataProvider.lenght;
// expanded length
// I assume you use xml as your data provider
// then you can count it like this
xmlListTotalSize(new XMLList(grid.dataProvider.source.source));
// or with casts
xmlListTotalSize(new XMLList((IHierarchicalCollectionView(view.grid.dataProvider).source as HierarchicalData).source));
and xmllist traversal function might look something like this:
private static function xmlListTotalSize(x:XMLList):int
{
var i:int = x.length();
for each(var xChild:XML in x.children())
i += xmlListTotalSize(xChild.children());
return i;
}
I generally find indexOf very useful, to get an index directly, and not writing 3-4 lines of for loop to get a match.
Is there any similar function, say like indicesOf , to get an array of all possible matches ?
Or may be having a different name, but acts as a shortcut as beautifully as "indexOf" ?
As you don't mind creating a new Array, you can use the filter() function - it executes a function on each item of the array, then returns a new Array with the items that return true:
// our comparison function
function myCompFunction( element:*, index:int, array:Array ):Boolean
{
return ( element > 10 );
}
var ar:Array = [5,10,15,20];
var ar2:Array = ar.filter( myCompFunction ); // ar2 is now [15,20]
It's not exactly indicies, but then again, you don't need to dereference your objects.
NOTE: because it's calling a function on each element, looping through the array yourself will still be quicker
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/Array.html#filter()
Unfortunately, there is not such shortcut. indexOf works for only one item, and there is no alternative for multiple items.
The solutions are obvious - iterate over the entire array or use some kind of sort on the array. Maybe there are other methods, but they are almost the same - loop through everything and check. Sorry to say it, but that's the way it is :)
I'm trying to create a flash application that will keep track of user generated values. The app should basically allow the user to input the name of the item and it's cost. The total costs should then be added up to show a total value to the user. I can probably figure out how to add the values together, but I'm not really sure how to allow the user to create a list and then allow the user to save it. Can anyone point me towards a tutorial or point me in the right direction?
I am using variables to add user inputed numbers to come up with a total. The first problem is that actionscript 3.0 does not allow variables for texts. I just converted it to 2.0 to fix this. The second problem, is when I test the app and put in my values and click submit, I get NaN in the total values field. Is there a reason why it wouldn't add the values?
Here is the code I used for the submit button:
on (release) {
total = Number(rent) + Number(food) + Number(travel) + Number(entertainment) + Number(bills);
}
Am I missing anything?
Can I give the input text instance names and then give them variables? How are some ways to go about this?
Thanks for the help!
Have an object array, say for example
var stack:Array = new Array();
Then push the item name and it's cost to that array when user inputs, like
stack.push({item:AAA, cost:xx});
So that you can generate the list whenever you want with that array.
You have to see how this works in code. A list in actionscript could be stored inside an array, vector, dictionary or even an Object.
Var myList:Array = [];
myList.push({name: "item 1", cost: 5 });
myList.push({name: "item 2", cost: 7.5 });
If you want to grab the 'product' of "item 1" from the list, you have to create a function for that, lets call it getProductByName
function getProductByName(name:String):Object
{
for each(var product:Object in myList)
{
if (product.name === name) return product;
}
return null; // no match found
}
You can call that function like this:
var product = getProductByName("item 1");
trace(product.cost); // 5
And you can alter the product, so lets make it more expensive
product.cost += 1;
trace(product.cost); // 6
Have fun! If you are using classes, you would create one for the product, with public name and cost, and in that case you'de better use a vector, to ensure working with the right type.
This is what fixed the issue for me in action script 3.0:
myButton.addEventListener(MouseEvent.CLICK, addThem);
function addThem(e:MouseEvent)
{
totalField.text = String ( Number(field1.text) + Number(field2.text) + ....);
}
I also had to name the instances appropriately.
