Returning the array before the function is complete & Angular JS


Returning the array before the function is complete & Angular JS

I wish this helpful for you You are trying to return from an asynchronous function; you'll always get unreliable results from that, you need to pass in a callback function that handles whatever operation you want at the end of your async... Like:
code :
.service('CompileYelpResults', function (YelpResource) {
    var self = this;
    self.results = [];

    self.compileYelp = function (mapArray, callbackFn) {
        for (var j = 0; j < mapArray.length; j++) {
            YelpResource.getListings({term: self.yelpSearch, ll: mapArray[0]}, function (response) {
                self.results.push(response.businesses);
                        console.log(self.results);
            });
        }
        callbackFn(self.results);
    };
});
var parsed = CompileYelpResults.compileYelp(self.MapRouteArray, function(result) {
    console.log(result);
});
var logged = CompileYelpResults.compileYelp(self.MapRouteArray, function(result) {
    console.log(result);
});

var stringified = CompileYelpResults.compileYelp(self.MapRouteArray, function(result) {
    JSON.stringify(result);
});

How to wait for function to complete before returning?

How to wait for function to complete before returning?

Any of those help You're on the right track. Assuming you want to click the element, wait for a page transition, then check the resulting URL, you could do something like:
code :
clickIDverifyURL: function (elementURL) {
    return function (element) {
        return this.parent
            .then(function () {
                return element.click();
            })

            // Wait for the page transition. This can be a sleep, or you can search for an
            // element that should be on the new page (intern will implicitly wait for it
            // to appear), or use pollUntil to wait for a more specific condition.
            .sleep(1000)

            // Get the page URL
            .getCurrentUrl()
            .then(function (url) {
                assert.strictEqual(url, elementURL);
            });
    }
}
.findElementByCssSelector('.someselector')
.then(myModule.clickIDverifyURL('expectedURL'))
findBySomething: function (selector) {
    return function () {
        var setContext = arguments[arguments.length - 1];
        return this.parent
            .findByCssSelector(selector)
            .then(function (element) {
                setContext(element);
            });
    }
}
this.remote
    .then(myModule.findBySomething('.selector'))
    .then(myModule.clickIDverifyURL('expected URL'))
Returning a value in function export using promises when second function is complete

it should still fix some issue I'm trying to return a value after a promise runs a function once all promises are completed like the code below. , You can return the promise chain from your component:
code :
export function userRunner(userData) {
    return Promise
        .all(promises)
        .then(function (results) {
            return plotChart(results);
        })
}
import { userRunner } from './graph'

userRunner(userData).then(function (chartedResults) {})

should help you out I have this method in my service : , You are confusing the Observable map with the array map:
code :
.map(response => response.map((line) => PriceRule.fromJson(line));
.map(response => response.map((line) => Object.assign(new PriceRule(), line));
return this.http.get<PriceRule[]>(this.url);

Evaluatejsonpath returning complete array

Evaluatejsonpath returning complete array


By : cfour

Hope that helps Your JSONPath in SplitJson needs to point to an array to be split. If, after that, your EvaluateJsonPath points at a field that is an array, the array will be returned. If you want a flow file for each element in that array, you'll need another SplitJson processor. If your EvaluateJsonPath is putting the result(s) in an attribute, the flow file content will remain the same (i.e. the contents of the original incoming flow file). The current version of NiFi has a jsonPath function in Expression Language (https://nifi.apache.org/docs/nifi-docs/html/expression-language-guide.html#jsonpath) that you can use to manipulate the JSON content in the attribute.
