I know that you can pass data to a view using:
navigator.pushView(views.LoadoutView, list.selectedItem)
But what if I pass that data, and then want to pass another piece of data to the same view using a similar method?
Can I get/set a new property or can I write the current data to an xml file as soon as it is received?
Here is a little diagram I made of what I'm trying to achieve (I spent hours on it :P).
From what I've understood, you need to push multiple objects to a view at once, correct?
The data object can only be a single object or object reference, which means that if you want to push more than just your list.selectedItem, create a new Object (a generic one will do) that contains both your properties and push it, much like the following;
var myDataObject:Object = {firstPieceOfData:list.selectedItem, secondPieceOfData:yourSecondObjectHere};
navigator.pushView(views.LoadoutView, myDataObject);

I have an array in Mule that I am iterating over. I believe the for each makes a copy of the array I pass it and iterates through that. Is it possible to access that copy by reference and modify it? Based on certain conditions I would like to add extra elements to the array. I have tried to use vars.rootMessage but it does not give me what I am expecting.
No. Just create a new array in a variable and add to it. To provide more context, Mule 4 variables live in Mule Events, which are immutable. That means that a change results in the creation of a new event.
I have this solution that helps me creating a Wizard to fill some data and turn into JSON, the problem now is that I have to receive a xlsx and turn specific data from it into JSON, not all the data but only the ones I want which are documented in the last link.
In this link: https://stackblitz.com/edit/xlsx-to-json I can access the excel data and turn into object (when I print document.getElementById('output').innerHTML = JSON.parse(dataString); it shows [object Object])
I want to implement this solution and automatically get the specified fields in the config.ts but can't get to work. For now, I have these in my HTML and app-component.ts
https://stackblitz.com/edit/angular-xbsxd9 (It's probably not compiling but it's to show the code only)
It wasn't quite clear what you were asking, but based on the assumption that what you are trying to do is:
Given the data in the spreadsheet that is uploaded
Use a config that holds the list of column names you want returned in the JSON when the user clicks to download
based on this, I've created a fork of your sample here -> Forked Stackbliz
what I've done is:
use the map operator on the array returned from the sheet_to_json method
Within the map, the process is looping through each key of the record (each key being a column in this case).
If a column in the row is defined in the propertymap file (config), then return it.
This approach strips out all columns you don't care about up front. so that by the time the user clicks to download the file, only the columns you want are returned. If you need to maintain the original columns, then you can move this logic somewhere more convenient for you.
I also augmented the property map a little to give you more granular control over how to format the data in the returned JSON. i.e. don't treat numbers as strings in the final output. you can use this as a template if it suites your needs for any additional formatting.
hope it helps.
I need to pass data between views in my client-server app. For simple string value, I can put them as attributes on the target element and read the value when the select event is triggered on it. From there, I can pass this string value onto the next document pretty easily.
But the problem comes with much more complex data that's in JSON format. I tried doing JSON.stringify(myData) and putting this value in an attribute. But the compiler doesn't like the { in this attribute value.
I could probably try escaping all the different characters that the compiler has problems with. But I don't think that's a good idea.
Is there any way of implementing jQuery's .data() functionality in TVML and TVJS ? Or is there any other way that makes sending data between views a possibility ?
You can pass your data as URL parameters. Then in the new view, get them using Javascript.
EDIT: And I see in the comment above you came to a similar conclusion.
You could keep your data in a semi-global associative array. Store the key in an attribute on the element and use that to get your data structure.
Ex:
var globalData;
function onSelect(e){
var id=e.target.getAttribute("id");
var specificData=globalData[id];
}
I have a REST API call which fetches JSON data in tree format....
Now, i store that in a scope variable $scope.treeData []
And this is connected to a ivh-tree.
Now, i am using interval to update this data every 60 secs
The problem is:
The moment the new data is fetched and replaced in the scope variable, all the properties of the tree is lost and its re-initialized to default (the new data is present though).
By Properties, i mean, checkbox selections or node expansions etc.
The tree refreshes to the basic minimal unexpanded format.
So, is there a way by which i can update the existing scope variable with only the changed data i.e. add new nodes or remove existing nodes or change some property ?
Or is there any tree widget which i can use.
Its difficult in finding angular components for tree which atleast preserve the tree state on data update
To add the new nodes you could use angular.merge:
angular.merge($scope.treeData, json.treeData)
You would still have to remove the elements manually though.

I have a controller that access a WCF service which returns a Json object (collection). All rows are of same type, but at different calls the row stricture is different (the return object comes from a user-built sql query, executed with executeReader and serialized as Json
So I don't know the row structure upfront.
What I need is an easy way to pass this Json string to something which will generate a view of type list on the fly for it. Doesn't matter formatting, etc, just should be output easily as a table.
Does anyone knows how can I accomplish this?
Another option might be to have something that generate the view on the fly for a IEnumerable of anonymous objects (since using this I could convert the json to a list of anonymous)
EDIT
I found something that does pretty much what I need, except it display metadata about passed object.
It is preetyPrint.js, and I integrated it in my page as below:
In my controller I set the result json object to ViewBag.Result, and in the view I used this code:
<script src="#Url.Content("~/Scripts/prettyprint.js")" type="text/javascript"> </script>
<div id="resultGrid"></div>
<script>
var resultObject = #Html.Raw(ViewBag.Result);
var ppTable = prettyPrint(resultObject);
document.getElementById('resultGrid').appendChild(ppTable);
</script>
Does anyone knows such script that actually "dump" the data instead of metadata?
Thanks.
You should create a class to deserialize to if you know the properties of the row. Then use the JavaScriptSerializer class to deserialize to a list of your new class you created. Then you can take a look at the WebGrid class to output the HTML, or just manually iterate over the property metadata in your view.
Creating a custom class will provide you the ability to use metadata to control formatting or other display attributes of the output.
If you cannot create a custom class, you can always use Json.NET or the JavaScriptSerializer to deserialize to a list of dictionary objects or ExpandoObject / Dynamic's or something. Then you would have to manually write something to iterate the keys I think. The ModelMetadataProvider in MVC may be able to handle these allowing you to just iterate the properties in your view code.
