QUESTION
I am trying to get the value of the input number field but it returns me the said error.
HTML:
Enter the First number :
JavaScript:
var num1 = document.getElementById("fornum1").value;
The whole point of the website is to create a basic calculator that uses buttons to display outputs on a input field.
...ANSWER
Answered 2022-Mar-19 at 08:37First of all, as @mplungjan suggested in the comments, move the script:src to after the tag. Next, you declare num1 and num2 in the start of the script, meaning if the input's values will change the program will still have num1 and num2 set to 0. So all you need to do is when the button is clicked, check the input's values again for a change. Lastly, the checking the input's values returns a string, not a number as you would want in a calculator. So all you need to do is convert the string into a number, using ParseInt.
QUESTION
I have a dataframe column that has a string, which may include several spaces. I want to use separate from tidyr (or something similar) on the space after the first time a keyword (i.e., fruit_key in the sample data) appears, so that I separate the one column into two columns.
Sample Data
...ANSWER
Answered 2022-Mar-16 at 16:07If we need to use separate with sep, then create a regex lookaround - "(?<=) " i.e. split at the space that succeeds the fruit_key word and as is not vectorized, collapse into a single string with | (str_c)

QUESTION
I have column A with items such as Apples, Bananas, Grapes, Plums, Cherries,
B1[column:row] contains a drop drop of column A. I want to be able to build a drop down for C1 then D1, etc... based on the values in B1 - meaning if I select Plums in B1, the drop down in C1 should now have just Apples, Bananas, Grapes, Cherries, then if I choose Apples for C1, D1 should have only Bananas, Grapes, Cherries
Is this possible, if so any help wold be greatly appreciated

Answered 2022-Mar-07 at 00:45So you have column A with items such as Apples, Bananas, Grapes, Plums, Cherries as shown in the screenshot below,
Please follow the steps to accomplish the task,

QUESTION
My code uses conditional formatting to look at the row values in Column A "Order ID", compares them, and then formats the cell if the row values are different. Instead of formatting the cell, how do I format the entire row based off of consecutive row values in Column A "Order ID" being different?
Said differently - if the value in Column A "Order ID" is different from the previous value in Column A "Order ID", I want to format the entire row that is different. My data is variable everyday so I need to use VBA!
Here is the output of my current code:

QUESTION
I have an array, and I want to print them in div tags, and also when I make changes on the array, I want the change also to occur on divs (for example when I delete an item, div print of item also be deleted; or change the value of an item, expect thing happen to the div of the item). I made a little research and I found something I didn't know before that called Proxy object. I wrote the following code:
...ANSWER
Answered 2022-Feb-17 at 12:33Another possible solution could be based on an hand-knitted model and controller logic.
One would entirely separate the pure controller tasks, letting them only work directly with the DOM and with a modeled abstraction of the initially provided list items/values.
The model itself could be e.g. a Map based registry which implements the logic of always being in control of the correct list state.
Thus, in addition to the most obvious register/deregister methods, there will be sanitizing and check tasks that prevent e.g. double registering of (potentially) equal items/values. Such a registry model could also provide getters for special list representations of its registered items like e.g. providing the current array of just each item's text content or an array of each item's model.
As for the latter, such a model in addition to e.g. its id and text value would also feature its own view, e.g. an elm reference of the to be rendered/removed element node.
In order to keep each item specific DOM node and/or each item's model free of controller logic, the main controller task uses event delegation [1],[2] by listening to / handling the double-click event at the list's root-node exclusively.
The next provided example code demonstrates how the main controller task operates both the DOM and the item list abstraction ...
QUESTION
I have a table with x num of rows, I have a second table with the same number of rows but different columns and metadata, they have different table models. but each row represents the same object (a song).
I want to synchronize row sorting between the two tables so for example if I sort on column 2 of table 1 then rows of the table will be sorted in the same order. But currently, I just have sorted by matching sort keys so sort on the same column (but because different data get different results)

QUESTION
My two hash/maps are as below. I want to get the value corresponding to the key from the first map and second map and then add them to table
Map 1 [ { "key": "1", "value":"Potato" }, { "key": "2", "value":"Chilly" } ]
Map 2 [ { "key": "1", "value":"Apple" }, { "key": "2", "value":"Plum" } ]
I want the data in the fashion so that I can fetch data for the same key from both the map at the same time
...ANSWER
Answered 2022-Feb-09 at 07:18You need to parenthesize the map concatenation in order to be able to use the built-in ?keys, so (map1 + map2)?keys. Also, you might want to check for empty values if the maps are not equal by suffixing your expression with !"default value", or simply ! if you want to have no default:
