So I have the following object from my controller, which has a name, a list of beans and a list of operations:
{
"name": "Charge",
"beans": [
],
"operations": [
{
"name": "getSize",
"returnType": "java.lang.Integer",
"description": "empty description",
"parameters": [
]
},
{
"name": "truncate",
"returnType": "java.lang.Void",
"description": "empty description",
"parameters": [
]
},
{
"name": "count",
"returnType": "java.lang.Integer",
"description": "empty description",
"parameters": [
{
"name": "javaCode",
"type": "java.lang.String",
"value": null
}
]
},
{
"name": "update",
"returnType": "java.lang.Integer",
"description": "empty description",
"parameters": [
{
"name": "javaSelectCode",
"type": "java.lang.String",
"value": null
},
{
"name": "javaUpdateCode",
"type": "java.lang.String",
"value": null
}
]
},
{
"name": "delete",
"returnType": "java.lang.Integer",
"description": "empty description",
"parameters": [
{
"name": "javaCode",
"type": "java.lang.String",
"value": null
}
]
},
{
"name": "dump",
"returnType": "java.lang.Void",
"description": "empty description",
"parameters": [
{
"name": "javaSelectCode",
"type": "java.lang.String",
"value": null
},
{
"name": "destinationPath",
"type": "java.lang.String",
"value": null
}
]
},
{
"name": "select",
"returnType": "java.lang.String",
"description": "empty description",
"parameters": [
{
"name": "javaCode",
"type": "java.lang.String",
"value": null
}
]
}
],
"$$hashKey": "object:620"
}
Basically I want to display all the operations from this object in a dropdown menu.
So I was thinking of having something like:
<div ng-repeat="operation in object.operations">
{{operation.name}}
</div>
Except the code above doesn't display anything on the screen, no errors in the console, nothing.
Any help would be much appreciated!
EDIT:
Javascript service:
app.controller('selectAll', ['$http', '$scope' , '$rootScope', function ($http, $scope, $rootScope) {
$scope.response;
$scope.operations;
$rootScope.$on("invokeSelectAll", function(){
$scope.invokeSelectAll();
});
$scope.invokeSelectAll = function(){
$scope.response = $http.post('/invoke/selectAll/', $rootScope.dataObj);
$scope.object = JSON.stringify($rootScope.object);
console.log(" object operation from selectAll " + $scope.object);
$scope.response.then(function(data) {
$scope.responses = data.data ? data.data : "Select Operation not supported on this bean";
});
}
}]);

Use JSON.stringify() to create a JSON string from a JavaScript object.
Use JSON.parse() to parse a JSON string to a JavaScript object.
In your case, you need to use JSON.parse() because you get a JSON string from the server and want to parse it to a JavaScript object.
$scope.object = JSON.parse($rootScope.object);
you are using JSON.stringify which is used to change javascript object to string and store it as a string only.
You should Parse the data with JSON.parse(), and the data becomes a JavaScript object. and you can easily use that in ng-repeat.
Try it ,It will work fine

How can we convert non-standard hast (which is parsed from a Markdown file) to HTML?
For example, this is the HTML tree data I have:
{
"_path": "/hello",
"_draft": false,
"_partial": false,
"_empty": false,
"title": "Hello!",
"description": "",
"body": {
"type": "root",
"children": [
{
"type": "element",
"tag": "h1",
"props": {
"id": "hello!"
},
"children": [
{
"type": "text",
"value": "Hello!"
}
]
}
],
"toc": {
"title": "",
"searchDepth": 2,
"depth": 2,
"links": []
}
},
"_type": "markdown",
"_id": "content:hello.md",
"_source": "content",
"_file": "hello.md",
"_extension": "md"
}
How can I parse that 'body' bit to HTML in Node.js?
I tried to use hast-util-to-html:
import { toHtml } from 'hast-util-to-html'
console.log('data.body =', toHtml(data.body))
But I got the following error:
TypeError: Cannot read properties of undefined (reading 'toLowerCase')
I think the tag key in the data should be tagName for using hast-util-to-html. tag and prop are non-standard keys I suppose, how can I standardise them?
I am trying to upload my intent everything is working fine, i am writing script in V2 and everything works but for parameter webhookState data type is enum ( [here] ) and we have to enter following of the three values ( [here][1]) now when i enter any one and try to upload it shows.
" Unable to load file: SyntaxError: Unexpected token W in JSON at position 98 "
now when I pass WEBHOOK_STATE_ENABLED(or any one) in quotes code uploads successfully (because as per my knowledge it treats it as string and gets executed) and intent is created for my agent but webhook remains off and also training phrases are not there, i am certain that the parameter webhookState is not being activated when i pass in quotes(because of above mentioned reason) Same is the case with rest, like when i try to put in type of training phrases.

Please NOTE that in the attached Json i have put it in quotes so it would get successfully executed and will create intent.
In order for it to be valid JSON, the enum value should be wrapped in quotes. It's expecting the enum value as a String.
I've tried 100 different things, and spend days looking through Google and Stackoverflow, but I can't find a solution to this problem. Everything I call after the body of this API response returns undefined!

This response is from a batch call. If I call them separately, I can easily iterate through the responses, and get everything from them. When I call them in the batch though, I can't get past "body", and I need to use a batch call.
console.log(response[0].body); will return the object inside the body of the first part of the response, but console.log(response[0].body.data); returns undefined. I just don't get it. This should be simple but it's like there's a lock on the door and I don't have the right key.
I normally have no issue iterating through objects, so I don't need a generalized answer. I need help seeing whatever it is here that I don't see. Why does the console show undefined when I call anything after the body, and what do I need to be doing to get any of these values?
That JSON contains nested JSON. body seems to be a string. Use
var body = JSON.parse(response[0].body);
The values from the body are just strings.which are embedded as json.So firstly you would need to parse them using JSON.parse.
The code would be like
var body = JSON.parse(response[0].body);
Trying to get all JSON objects in an array. It's only returning the last one.
Here's a sample of my JSON:
{
"manufacturer":{
"name": "manufacturername",
"cameras": [
{
"name": "sdfsdfsd",
"type": "Audio device",
"resolution": "Unknown",
"channels": "1"
}
]
},
"manufacturer":{
"name": "manufacturername2",
"cameras": [
{
"name": "sdfsdf",
"type": "Camera",
"resolution": "720P/1.3MP",
"channels": "2"
},
{
"name": "D12",
"type": "Camera",
"resolution": "1080P/3MP",
"channels": "1"
}
]
}}
It is valid JSON.
Here's how I'm calling it:
//Get Manufacturer data
$http.get('data2.json').success(function(data) {
$scope.maninfo = data;
console.log($scope.maninfo);
});
The actual array is much longer - and it's just returning the last Object for some reason.
What you have is valid JSON, but it doesn't correctly express your intent. "manufacturer" (or "name", or "cameras") isn't a type name, it's a unique key into a collection of named values -- dictionary, map, hash, whatever(1). JSON data structures are just a subset of JavaScript object literal declarations (hence the name: JavaScript Object Notation).
So the example above is not an array, it's two successive value assignments to the "manufacturer" property of the same parent object. The parser is assigning the first one to the "manufacturer" property, then replacing that with the second (and in your original, larger) "array", it's then replacing that with the third, and so on.
The "cameras" properties in the manfacturer objects are properly functioning arrays. Just do the same at the higher level -- something more like this:
{
"manufacturers":
[
{
"name": "manufacturername",
"cameras": [
{
"name": "sdfsdfsd",
"type": "Audio device",
"resolution": "Unknown",
"channels": "1"
}
]
},
{
"name": "manufacturername2",
"cameras": [
{
"name": "sdfsdf",
"type": "Camera",
"resolution": "720P/1.3MP",
"channels": "2"
},
{
"name": "D12",
"type": "Camera",
"resolution": "1080P/3MP",
"channels": "1"
}
]
}
]
}
(1) Dictionary, map, hash -- or "associative array". But I didn't want to call it any kind of "array" in that paragraph, because the whole point is it's not the other kind of array.
I have QML LocalStorage using javaScript. In it I put object via JSON.stringify(). When I try to read the object from DB using JSON.parse() is returning : scanEscape a and I did't found a reference to this scan error JSON file:

Q1: What is this error ?
Q2: How to solve it?
P.S.: (Tested on Qt 5.2b & 5.1.1)
Bug was actually some missed debugging log in Qt. Upon creating Bugtrack issue problem was adressed and will be solved in next stable release (Qt 5.2.0).
