I need to dynamically create a multidimensional javascript array that matches this layout:
array_answers[0][1]:"yes"
array_answers[1][2]:"no"
array_answers[2][2-subquestion]:"text input"
array_answers[3][8]:"yes"
array_answers[4][8-subquestion]:"text input"
The first "[ ]" defines what question it is on the page (out of totalInputs)
The second "[ ]" defines what question from the database this is (questions already in order to match the corresponding input)
and the information following is the input I am trying to add
I have attempted to the following with no luck.
for(var i = 0; i < totalInputs; i++) {
array_answers.push([i]);
array_answers[i].push([questions[i]]);
array_answers[i][0] = "yes, no, or other text";
}
The last line is where it falls apart. It would make sense to me that I should be able to use [0] to indicate that I want the first array to be given this value but with no avail.
I have also tried:
for(var i = 0; i < totalInputs; i++) {
array_answers.push([i]);
array_answers[i].push([questions[i]]);
array_answers[i][questions[i]] = "yes, no, or other text";
}
but this gives me lots of empty arrays for all the numbers from 0 to whatever the value of questions[i] is.
What am I missing or is there a simpler way to do this in jQuery while still conforming to the target layout?
If I understand you correctly, you are trying to store questions and prompts (maybe?) together in a multi dimensional array. let me suggest a different way that should work.
const array_answers = questions.map(q => [q, "yes, no, other text"]);
This may be what you want
I am still not 100% sure of what you need, but i thought I would write an answer with my assumptions, that I can update as the information improves.
The first "[ ]" defines what question it is on the page (out of
totalInputs)
This part looks like you are correct, and need to use an array. But an array is just a list of "things", in your case, questions. So where you have this line:
array_answers.push([i]);
I'm not sure it is doing what you are expecting. This is adding a new array item, which is in itself an array, that contains a single number. So if totalInputs is 3, then that first line will result in this structure:
array_answers= [[0],[1],[2]]
I think what you actually might intend here is to simply house an array of question details. Now by the complexity of your keys listed for the second dimension, it looks like an object would be more appropriate.
The second "[ ]" defines what question from the database this is
(questions already in order to match the corresponding input)
So lets go ahead and create a single question.
var question = {
anythingYouWant: 'here',
2: 'even numeric keys'
}
// you can access the values in these ways
console.log(question.anythingYouWant)
console.log(question[2])
console.log(question['anythingYouWant'])
Now once you have a question object, you can then add it to your array_answers array with push.
array_answers.push(question).
If you have two identical questions like the one above, your array will look like this:
array_answers = [{
anythingYouWant: 'here',
2: 'even numeric keys'
},{
anythingYouWant: 'here',
2: 'even numeric keys'
}]
In order to access the questions within the array, you can simply use their index:
// access second question
var secondQuestion = array_answers[1]

Bit of a lengthy one so those of you who like a challenge (or I'm simply not knowledgeable enough - hopefully it's an easy solution!) read on!
(skip to the actual question part to skip the explanation and what I've tried)
Problem
I have a site that has a dataset that contains an object with multiple objects inside. Each of those objects contains an array, and within that array there are multiple objects. (yes this is painful but its from an API and I need to use this dataset without changing or modifying it.) I am trying to filter the dataset based of the key-value pairs in the final object. However, I have multiple filters being executed at once.
Example of Path before looping which retrieves the key-value pair needed for one hall.
["Hamilton Hall"]["Hire Options"][2].Commercial
After Looping Path of required key-value pair for all halls, not just one (the hall identifier is stored):
[0]["Hire Options"][2].Commercial
Looping allows me to check each hall for a specific key-value pair (kind of like map or forEach, but for an object).
After getting that out of the way back to the question.
How would I go about filtering which of the looped objects are displayed?
What I have Tried
(userInput is defined elsewhere - this happens on a btn click btw)
let results = Object.keys(halls);
for (key of results) {
let weekend = [halls[ `${key}` ][ 'Hire Options' ][4][ 'Weekend function' ]];
if(userInput == weekend) {
outputAll([halls[ `${key}` ]]);
}
}
That filters it fine. However, I run into an issue here. I want to filter by multiple queries, and naturally adding an AND into the if statement doesn't work. I also dont want to have 10 if statements (I have 10+ filters of various data types I need to sort by).
I have recently heard of ternary operators, but do not know enough about them to know if that is the correct thing to do? If so, how? Also had a brief loook at switches, but doesnt seem to look like what I want (correct me if I am wrong.)
Actual Question minus the babble/explanation
Is there a way for me to dynamically modify an if statements conditions? Such as adding or removing conditions of an if statement? Such as if the filter for 'a' is set to off, remove the AND condition for 'a' in the if statement? This would mean that the results would only filter with the active filters.
Any help, comments or 'why haven't you tried this' remark are greatly appreciated!
Thanks!
Just for extra reference, here is the code for retrieving each of the objects from the first object as it loops through them:
(Looping Code)
halls = data[ 'Halls' ];
let results = Object.keys(halls);
for (key of results) {
let arr = [halls[ `${key}` ]];
outputAll(arr);
}
You can use Array.filter on the keys array - you can structure the logic for a match how you like - just make it return true if a match is found and the element needs to be displayed.
let results = Object.keys(halls);
results.filter(key => {
if (userInput == halls[key]['Hire Options'][4]['Weekend function']) {
return true;
}
if (some other condition you want to match) {
return true;
}
return false;
}).forEach(key => outputAll([halls[key]]));
I am using IE 11.
I have an object array that is grouped using the lodash library. I want to be able to query the object and based on certain conditions come up with sums/counts. So for example, I have this object array.
I would like to have the result seen below but in an object like the image above
As you can see, each company in the group should have certain values based on the following criteria
How many times does 'company x' have a Total Count >3?
How many times does 'company x' have expectingFunding eq ‘Yes’>
How many times does 'company x' have fundedOnIKNS eq ‘No’?
I've tried quite a bit in the last couple of days but not success. I first declared 2 arrays so I can capture the unique values of company name and program. I also created an object to update when conditions were met. The only successful thing I was able to get was to keep it in an grouped object. All the values in the new object were wrong.
Here's an excerpt of the code:
const companiesSummary = {};
for (const company of Object.keys(myData)) {
companiesSummary[company] = {
totalCount: 0,
expectedFunding: 0,
IKNSFunding: 0,
};
for (const { TotalCount, expectedFunding, fundedOnIKNS } of myData[company]) {
companiesSummary[company].totalCount += TotalCount;
companiesSummary[company].expectedFunding += expectedFunding === "Yes";
companiesSummary[company].fundedOnIKNS += fundedOnIKNS === "Yes";
}
}
I get the error,
TypeError: myData[company] is not iterable
Here's a link to the pen
I would still like the result to be in an object array, so I can create an html table later. Any help would be much appreciated. Thank you!
Your code isn't working because you're taking myData, an array, accessing myData[company], an object (company is 0, 1, ...), and you can't iterate through an object with for...of. myData is definitely not the same object in your screenshot.
Your code excerpt might work if your myData object were the object in your screenshot.
db = new Array("myserver", "myfolder\\mydb.nsf")
dir = getComponent("Dir").value;
div = getComponent("Div").value;
lu = #DbLookup(db, "ManagerAccess", dir + "PP" + div, "DTManagers");
var a = [];
a.push(lu);
var item:NotesItem = docBackEnd.replaceItemValue('FormReaders', #Unique(a));
item.setReaders(true);
That code is on the querySaveDocument ssjs. The result I get from the #DbLookup (when I put in a computed field) look like this:
Pedro Martinez,Manny Ramirez,David Ortiz,Terry Francona
I tried doing an #Explode(#Implode) thing on it, but it doesn't seem to work.
The error I get in the browser just tells me that the replaceItemValue line is broken.
To test it, I pushed several strings one at a time, and it worked correctly populating my FormReaders field with the multiple entries.
What am I doing wrong?
I see several problems here:
A. In cases as described by you #Dblookup in fact would return an array. If you push an array into a plain computedField control it will exactly look as that you wrote:
value1, value2, ..., valueN
A computedField doesn't know anything about multiple values etc, it just can display strings, or data that can be converted to strings.
If you want to test the return value you could try to return something like lu[0]; you then should receive the array's 1st element, or a runtime error, if lu is NOT an array. Or you could ask for the array's size using lu.length. That returns the number of array elements, or the number of characters if it's just a plain string.
B. your code contains these two lines:
var a = [];
a.push(lu);
By that you create an empty array, then push lu[] to the first element of a[]. The result is something like this:
a[0] = [value1, value2, ..., valueN],
i.e. a is an array where the first element contains another array. Since you don't want that, just use #Unique(lu) in your replaceItemValue-method.
C. I don't see why replaceItemValue would throw an error here, apart from what I wrote in topic B. Give it a try by writing lu directly to the item (first without #Unique). That should work.
D. for completeness: in the first line you used "new Array". A much better way to define your db parameters is
var db = ["myserver", "myfolder/mydb.nsf"];
(see Tim Tripcony's comment in your recent question, or see his blog entry at http://www.timtripcony.com/blog.nsf/d6plinks/TTRY-9AN5ZK)
I've been given two arrays, each of which has several objects within them. I'm trying to make it so that when a certain dropdown selection is made, it pushes that "flight information" into a "flight summary" div, but I'm having a hard time figuring out how to do it.
var possibleDepartureFlights=[{year:2012,month:11,day:13,hour:17,minute:37,price:137.38} and so on];
var possibleReturnFlights=[{year:2012,month:11,day:18,hour:21,minute:45,price:189.46} and so on];
Each var has 10 objects within the array, each of which has all those properties.
And as a bonus question, I've figured out how to hide a "submit" button when the return flight selected is earlier than the departure, but I can't figure out how to make the submit button come back when a different selection is made!
function displayDivs() {
var departureValue = $('#departureFlightsControl').val();
var returnValue = $('#returnFlightsControl').val();
if (departureValue != "default") {
$('.CumulativeSummary').addClass('totalAvailable');
$('.DepartureSummary').addClass('flightChosen');
}
if (returnValue != "default") {
$('.CumulativeSummary').addClass('totalAvailable');
$('.ReturnSummary').addClass('flightChosen');
}
if ($('#returnFlightsControl').val() < $('#departureFlightsControl').val()) {
$('.SubmitArea').hide();
}
Sorry if this question is vague! I'm new to jQuery and JavaScript, so I'm not really sure what I'm doing (and I'm not even really sure what to Google for to find the answer to my problem(s)). Please use small words, as if you're speaking to a child. Thanks!
Your question is really too broad, anyways... Suppose you have following
var possibleDepartureFlights=[
{year:2012,month:10,day:13,hour:10,minute:37,price:137.38},
{year:2012,month:11,day:15,hour:17,minute:47,price:150.50}
];
The possibleDepartureFlights is an array of two objects and the first element of the array is the first object and it's {year:2012,month:10,day:13,hour:10,minute:37,price:137.38} and it's index is 0 and the second element in your possibleDepartureFlights array is the second object and it's {year:2012,month:11,day:15,hour:17,minute:47,price:150.50} and it's index is 1. Now, if you want to access the month property of the first item of the array then you can write like
alert(possibleDepartureFlights[0].month); // this will alert 10
For the month of the second item/object in the array you can write
alert(possibleDepartureFlights[1].month); // this will alert 11
To loop through the array and print out the each property of every objects, you can try this
for(i=0;i<possibleDepartureFlights.length;i++)
{
console.log(possibleDepartureFlights[i].year);
console.log(possibleDepartureFlights[i].month);
console.log(possibleDepartureFlights[i].hour);
console.log(possibleDepartureFlights[i].minute);
console.log(possibleDepartureFlights[i].price);
}
An Example Here.
Remember, this is only a short example and there are more about arrays and objects in JavaScript. Also remember that you can loop an object with for in like for loop. Also this one could be helpful too.
I need help with a loop... it's probably simple but I'm having difficulty coding it up.
Basically, I need to check existing Ids for their number so I can create a unique id with a different number. They're named like this: id="poly'+i'" in sequence with my function where i is equal to the number of existing elements. Example: Array 1, Array 2, Array 3 corresponding with i=1 for the creation of Array 1, i=2 for Array 2, etc.
Right now i is based on the total number of existing elements, and my "CreateNew" function is driven off x=i+1 (so the example above, the new element will be named Array 4). The problem is that if you delete one of the middle numbers, the "Create" function will duplicate the high number. i.e. Array 1, 2, 3 delete 2, create new-> Array 1, 3, 3.
I need an if() statement to check if the array already exists then a for() loop to cycle through all i's until it validates. Not sure how to code this up.
The code I'm trying to correct is below (note I did not write this originally, I'm simply trying to correct it with my minimal JS skills):
function NewPanel() {
var i = numberOfPanels.toString();
var x = (parseInt(i)+1).toString();
$('#items').append('<div onclick="polygonNameSelected(event)" class="polygonName" id="poly'+i+'"> Array '+ x +' </div>');
$('div[id*=poly]').removeClass('selected');
$('#poly'+i).addClass('selected');
$('#poly'+i).click(function() {
selectedPolygon = i;
$('div[id*=poly]').removeClass('selected');
$(this).addClass('selected');
});
}
THANK YOU! :)
Please clarify "The problem is that if you delete one of the middle numbers, ". What do you mean by delete? Anyway, the simplest solution is to create two arrays. Both arrays will have the same created id's. Whenever an id is created in the first array, an id will be added to the second array. So when it is deleted from first array, check your second array's highest value and then create this id in first array. I hope this did not confuse you.
Well it is hard to tell why you cannot just splice the array down. It seems to me there is a lot of extra logic involved in the tracking of element numbers. In other words, aside from the index being the same, the ids become the same as well as other attributes due to the overlapping 1, 3, 3 (from the example). If this is not the case then my assumption is incorrect.
Based on that assumption, when I encounter a situation where I want to ensure that the index created will always be an appending one, I usually take the same approach as I would with a database primary key. I set up a field:
var primaryKeyAutoInc = 0;
And every time I "create" or add an element to the data store (in this case an array) I copy the current value of the key as it's index and then increment the primaryKeyAutoInc value. This allows for the guaranteed unique indexing which I am assuming you are going for. Moreover, not only will deletes not affect future data creation, the saved key index can be used as an accessor.
