I am returning a query object from Coldfusion as a JSON string which I then parse into JSON in Javascript. It has a bit of a strange format when I finally log it though.
I am faced with two problems. First, I do not know how to access the lowest element (i.e Arthur Weasley) as I cannot use a number in my selector (response.DATA[0].0 doesn't work because the lowest field name is a number). Second, is there any way to assign the values in the columns section to the fields that are numbered 1, 2 and 3?
What I'm really asking is how do I select my lowest level of data? If that can't be done because of the numbers for field names, how do I change the names to something more fitting?
My data logged:
First entry of first entry of DATA = response.DATA[0][0]
So
name = reponse.DATA[0][0];
trainsThing = response.DATA[0][1];

I want to export chart data from a website.
Using console.log(Highcharts.charts[0].series[0].data) I can see the data I need.
I want the values stored under Highcharts.charts[0].series[0].data[n].category for n in [0, 1, ..., N_data_points-1] (These values are the time-stamps of the data points in the plot.)
When I try to use JSON.stringify(Highcharts.charts[0].series[0].data) to write the whole data attribute I get Uncaught TypeError: Converting circular structure to JSON.
How can I get that data[n].category values for all n data points?
Note that the x axis data can be obtained straightforwardly via Highcharts.charts[0].series[0].processedXData, but these are not the dates, just consecutive integers.
Also, I don't necessarily need to do this via console. If it's possible to get the data via, say, a Python script, that would do as well.
You can adapt the python/selenium script here.
Most of the stuff remains as is, except for obvious changes (change the url, etc).
You can get the category data of each data point with:
dates = []
for i in range(len(values)):
date = driver.execute_script('return Highcharts.charts[0].series[0].data[{}].category'.format(i))
dates.append(date[0])
EDIT: as pointed out in a comment, you can get the category data without a for loop using:
categories = driver.execute_script('return Highcharts.charts[0].userOptions.xAxis[0].categories')
I'm still learning Javascript and I'm trying to parse a value from a cookie in a specific key:
I'm using this current line:
const cookieObj = new URLSearchParams(document.cookie.replaceAll("; ","&","|"))
cookieObj.get("LG_AFF_TRK")
LG_AFF_TRK is the key that I'm pulling the value from. Doing so creates the output value of the following:
1|2|3|4|5|6
Each number represented would be a value that will have a random number of characters -and- could possibly be empty but each section always be separated by the "|" symbol.
How can I pull a specific value? As an example question, what do I need to do pull value 3?
I'm trying to understand this logically and my guess is I have to create an array first?
I am struggling to find anything on the internet related to this one.
You can easily name a range in excel and it's treated as an array.
An example would be the average formula. You can feed a list from a named range into the formula.
Named Range "list" contains the values:
1,2,3,4,5,6,7,8,9,10
Named Range "list2" contains the values:
2,3,4,5,6,7,8,9,10,11
Currently in excel, this is possible.
=Average(Number1,[Number2], ...)
=Average(List1,List2)
Would it be possible to do ->
Average(list[1],list[6])
I want this to make my formulas more simple.
I have a large list of people and instead of doing
B1!H4, B1!h5
I would love to do N[1], N[2], N[3]
Thank you all!

You can use INDEX():
=AVERAGE(INDEX(list,1),INDEX(list,6))
Where list is a named range.
I have the results from Google place details. I would like to parse the phone number out of it. How could I do so? I am using OpenRefine and using fetching column on the basis of another column.
Here is an example of Google Place JSON.
As you can see, "formated_phone_number" is a direct child of "result". In Open Refine, you can extract this element using the following GREL formula:
value.parseJson().result.formatted_phone_number
If there are more than one phone number, use a for loop to iterate over the array. The syntax in Open refine is:
forEach(value.parseJson().result, x, x.formatted_phone_number)
(x is a variable name, you can use it or what you want instead.)
The result will be an array. Since an Open Refine column can only display strings, numbers and dates, you must convert the array to string using the join function (and a delimiter of your choice).
forEach(value.parseJson().result, x, x.formatted_phone_number).join('::')
I have an object in Parse .com database that can receive thumbs up votes. I want to keep track of which users have provided a thumbs up to prevent the same user doing it again. I am thinking of adding a field to my object called "voters" that will hold the list of voting users.
Should this be an array of usernames or a JSON with keys as the usernames?
Why would I use an array if i could use a json map and do O(1) lookup of the names on the keys?
ie object.voters[uername] = undefined then no votes?
Use Array if you need just the name of the voter .
Use Json if you need more info than just the name .
Why is that if u need just the name just making an array with the voter names first will be easy second it will be faster t process .
but if you need something like
voter={"name":"foo","age":"25"}
as you see we can use the powerof json to save multiple info about one user and anyway each voter must be within a single array so you can iterate over them
UPDATE---
to find the index of a name in an array just use array.indexOf("the name") what this will return is the index number of the name if the name doesnt exist it will return just -1 so a simple if else can handle this
UPDATE---
And here i found a performance test to compare which is faster to lookup whitin an array or an object and seems arrays still win this.
