I am able to render a google map on a flex canvas. I create the map using the code below and then place markers on it in the onMapReady method (not shown)
var map:com.google.maps.Map=new com.google.maps.Map();
map.id="map";
map.key="bla bla";
_mapCanvas.addChild(map);
map.addEventListener(MapEvent.MAP_READY,onMapReady);
It all works fine. However, if I remove the map and then set _mapCanvas to null, then run exactly the same code again, the onMapReady event does not fire. It is weird, but once a map has been created and deleted, the onMapReady event never seems to fire again.
Anyone got any ideas?
Thanks.
I still don't know why this was happening, but I worked around the issue by creating the map as an application-level variable, only instantiating it once, and then adding and removing it from canvases as required. Not ideal, but at least I can now display and remove a map dynamically, even if it exists in memory between invocations.

I created a click event in adobe launch which will capture the value of the link and send it to analytics. I have created a data element for saving the value and in my DOM I am saving value in local storage.
Local storage code:
$('.card').click(function() {
var name = $(this).text();
localStorage.setItem('productName', name);
});
My problem is when I click the first link no value got saved, but after when I click second link it saves the value of first link and on third link saves value of second link and so on. I want to save current link value in evar3 variable.
Data element:
Rule:
Set variables:
Thanks,

I'm scratching my head a little bit about why your jQuery selector doesn't match your Rule selector, but that's probably not immediately related or relevant, considering you said you are seeing data pop, in general, so at face value, I'm going to ignore that.
But in general, it sounds like your jQuery code is getting executed after the Rule is evaluated, so it's effectively one step behind. I'm not sure there's much if anything you can do about that if you aim to keep two separate click event listeners like this.
You're going to have to restructure to have one chain off the other (which I don't think is actually feasible with jQuery > Launch as-is. Maybe if you write two separate custom code blocks with promise chaining but that kind of sidesteps Launch and IMO is over-complicating things to begin with (see below)). Better yet, merge them into a single click event listener. On that note..
Why do you have two separate click event listeners? Is the sole reason for this to pass off the link text? Because you can reference the clicked element in the Launch Rule itself.
You should be able to reference %this.innerText% in the Set Variables fields. Or you can reference this object in custom code boxes within the Rule.
IOW at face value I don't see why you need or should be creating/using that jQuery listener or pushing to local storage like that.
Update:
You commented the following:
I tried with %this.innerText% it is also not showing current values. I
am pushing the value first to local storage because my link values are
generating on runtime through an API. They are not hardcoded. I am
also trying to figure out why my rule is getting fired before my
jquery is evaluated. But when I check in console using
_satellite.getVar('Product Name'); it shows me the correct value, but in debugger console value is wrong. Can you show me the way you want
to create rule to getting it fired correctly ? Thanks,
Okay so your link values are generated runtime through an API call? Well okay now that sounds like where the (timing) issue is, and it's the same issue in principle I mentioned you prolly had between the jQuery and Launch code. Assuming you can't change this dynamic link functionality, you have two options:
1. Explicitly trigger a launch rule (direct call rule) in a callback from the API code that's generating the link values.
This is the better method, because you won't have race condition issues with your API vs. link tracking code. The biggest caveat about this method though is that it requires requires you to actively add code to the site, which may or may not be feasible for you.
I have no idea what your code for generating the link looks like, but presumably it's some ajax call and generated from the success callback. So in the callback, you'd add a line of code something like this:
_satellite.track('product_image_click', {
text : elem.innerText
});
Again, I don't know what your API code that generates the link looks like, but presumably you have within it some element object you append to or update the DOM, so for this example, I will refer to that as elem.
'product_image_click' - This is the value you use for the direct call rule identifier in the interface, e.g. :
And then _satellite.track() call also includes an object payload in 2nd argument that you can pass to the direct call rule. So in the code above, I set a property named text and give it a value of elem.innerText.
Then, within the direct call rule, where you set variables, the data you passed can be referenced from event.details object within custom code box (e.g. event.details.text), or using % syntax within the interface fields (e.g. %event.details.text%).
2. Make use of setTimeout to delay evaluating the link click.
The one advantage of this method over option #1 is that it is passive. You don't have to add code directly to your site to make it work.
However, this is the shadier option, because you don't really know how long it will take for your link to be generated. But generally speaking, if you can determine it takes on average say 250ms for the link generation API to do its thing, and you set the timeout to be called at say 300-500ms, then you will probably be okay most of the time. However, it's never a 100% guarantee.
In addition, if clicking on the link ultimately redirects the visitor to another page, then this solution will likely not work for you at all, since the browser will almost certainly have navigated before this has a chance to execute. Because of this, I normally I wouldn't even mention this as an option, but since you mentioned this link involves an API that generates the link values when clicked, I figured maybe this isn't a navigation / redirect link, so maybe this is an option you can go for, if you can't do option #1.
First, create a direct call rule the same as shown in option #1. This will be the rule that receives the link text and makes the Adobe Analytics (or whatever other marketing tag) calls.
Then, create a separate rule as a click event, similar to what you are currently trying to do (listening for the link click, based on your css selector). In this rule, you won't be setting any AA variables. Instead, add a custom js box with code like this:
var elem = this;
(function (elem) {
window.setTimeout(function() {
_satellite.track('product_image_click', {
text : elem.innerText
});
}, 500);
})(elem);
So when the rule is triggered, it will create a setTimeout callback to call the first rule, passing the link text in the payload. And.. hopefully the 500ms timeout shown in the code example is enough time for the API to do its thing. You may be able to adjust it up or down.
Rather than defining it in Data Element I would say its better to keep it directly in the Rule itself. Please try with this %this.#text%.
Let me know if this helped.
Question
I'm working with Adobe Scene7 BasicZoomViewer and I'm looking for a way to tell the ZoomViewer to reset the zoom so that the user is no longer zoomed in on an image but instead will show the default "zoom" level.
What I've found
The closest thing I found to what I need is this reset property ZoomView.reset which "Resets the viewport when the frame (image) changes. If set to 0 it preserves the current viewport with the best possible fit while preserving the aspect ratio of the newly set image".
This looks close to something I need but it states that it will reset or preserve the aspect ratio when a new image has been inserted but I am not inserting new images.
Demo from Adobe
There is a button on the image that the API inserts into the page that resets the zoom level. Adobe provides a demo page that shows what I'm working with. If you look at the bottom left, the right-most button is the reset button. When clicked, it has to make some kind of API call and I need to figure out which one it is.
Edit
I've been able to find a minified version of the BasicZoomViewer and I am currently attempting to make sense of the code.
There is an event listener placed on the "Zoom Reset Button" that just simply calls a reset() method on line 274 in the uglified version of the file. Currently, I am trying to make sense of the file and figure out how to access this method.
c.zoomResetButton.addEventListener("click", function () {
c.zoomView.zoomReset()
});
I will be answering my own question. If someone finds a better way please feel free to answer as well.
tldr;
Create a variable to hold the instance of your s7viewers.BasicZoomViewer() and inside of that you can access the event handlers and much more.
Example of calling the reset zoom handler
// instantiate the s7viewers class and save it in a variable
var s7BasicZoomViewer = new s7viewers.BasicZoomViewer({
containerId: 's7viewer',
params: {
asset: assetUrl,
serverurl: serverUrl
})
// example of how to call the "zoomReset()" method
s7BasicZoomViewer.zoomResetButton.component.events.click[0].handler()
Explanation
After digging through the minified code that was uglified I found an event listener on the s7zoomresetbutton DOM class name, or perhaps it's watching for the ID of that DOM element which is the same ID as the container div for your S7 BasicZoom Viewer plus some added text to make this ID unique. For example, if the container div is s7viewer then the reset zoom button will have an ID of s7viewer_zoomresetbutton.
Now, going through the code I found this event listener which let me know there must be some way to call the zoomReset() method.
c.zoomResetButton.addEventListener("click", function () {
c.zoomView.zoomReset()
});
In the code above, the value of c is this or in other words it's the instance of your S7 BasicViewerZoom and in my case I have multiple depending on how many images I need to zoom on.
When instantiating the s7viewers class you can then reference that instance later and access the event handlers on each button and other properties and methods.
From there it was just looking through the object returned from the instance and calling the handler for the reset button.
I have a cytoscape graph added to my web app. In the core's configuration I've set the boxSelectionEnabled to true.
This is letting me draw a Box with holding Shift or Ctrl around graph elements.
Now i am trying to read all these elements upon the boxend event of graph like this,
this.cy.on("boxend", lang.hitch(this, function (event) {
console.log("boxend");
//read selected elements of graph by boxselection
}));
But, this even is not triggering. I tried with other box events such as boxstart,boxselect,box but those are not working as well. Although, I tried same with events such as tap,cxttap events and they are working fine without any issue.
So, is there any way to get all the box selection elements from graph with these events.
Thanks,
Suraj.
cy.on('boxend') seems to be working fine. You probably have an issue with wrapping the callback the way you have.
Following Google's documentation:
https://developers.google.com/maps/documentation/javascript/reference#FusionTablesLayer
https://developers.google.com/maps/documentation/javascript/reference#FusionTablesMouseEvent
There doesn't seem to be any documented way of capturing a rightclick event on a FutionTablesLayer like there is on the Map object. Has anyone figured out how to capture a rightclick (or contextmenu) event?
Even getting the x/y coordinates in pixels would be helpful since I could use those to find the latlng and query the FusionTable myself somehow... but it looks like the rightclick event on the Map is canceled or prevented from firing.
I'm afraid this is not possible.
The map would respond to the rightclick when you set the clickable-option of the layer to false, but this wouldn't help you much, because the latLng-property would contain the click-coordinates on the map and not the position of the marker.
I'm removing an UIComponent but parts of it last being visible.
It redraws only when I move mouse around or something. I tried to do validateNow() on its parent, tried to do setTimeout(validateNow, 100) but it doesn't help. When I call it by setTimeout it seems these artifacts shown more rarely but it doesn't solve a problem in all cases. Please guide me someone to read about validateNow(), how it works and how to make these things correctly.
The code is below:
protected var bubble: SpeechBubble;
// creation
bubble = new SpeechBubble();
map.addChild(bubble);
//...
// removing
bubble.visible = false;
map.removeChild(bubble);
map.validateNow();
setTimeout(map.validateNow, 100);
map is Google Map for Flex.
The reason this is happening is because you're messing with the Google Maps drawing logic. You should look at the developer guide provided by google. It mentions in the controls section that to create a custom control, you need to extend ControlBase.
You may need to trigger invalidation before calling validateNow(). The call to validate now causes the code to check if any of the invalidation flags are set (properties, display list, or size) then for each calls the appropriate method to correct the invalidation (commitProperties, updateDisplayList, measure) in your case it sounds like it's just not doing the clear call to the graphics or redrawing appropriately so you may need to call
bubble.invalidateDisplayList();
bubble.validateNow();
Also hope one of these solutions works out for you, generally speaking forcing validation at a given time is not usually a good idea as the framework components should trigger the appropriate invalidation and subsequent validation in it's life cycle, but I can't say I haven't done this myself :).

You may use includeInLayout property
bubble.visible = false;
bubble.includeInLayout = false;
