Attempting to make nested questions appear dynamically... C# ASP.Net Database First,

Idea for making elements visible or invisible:
So… how the loop works right now is it for each category, it loops through each question in each category.
The idea is: Each question can be answered yes or no, and then for each question answered yes, there can be up to 5 dates added.
What I want to do:
-If yes, first date appears:
-If the first date is answered, then a second question appears, and so on.
These questions are stored in a sql server like so:
I want only the inner loop to have this ability to be visible or invisible..
My thought is to do a nested loop and check check on each element.
//Psuedo code
//For each first question which has 5 sub questions that are all set to hidden:
var questioncount = (count of the first questions)
for(int i = 0; i<questioncount; i++){
// set first variable to hold the first questions object.
var element(‘#questionElement’ + i);
// set firstElement to selected answer
var isAnsweredYes = firstElement.(‘Yes’);
for int j = 0; i<subQuestionCount; j++)
if (isAnsweredYes == True){
// jQuery selector to get an element
var query = $('#element' + j);
// check if element is Visible
var isVisible = query.is(':visible');
if (isVisible === true) {
// element is Visible
// do nothing
} else {
// element is Hidden
query.show();
}
else
{
//do nothing
}
}
}
Does my logic seem forward? or can anyone advise me in a better way?

I would use a button that says "Add another date", which is displayed under the last date field as soon as at least one is visible. That way you won't have to decide on a certain number (e.g. 5) as the maximum, plus I think it's a rather intuitive way of extending a form.
On each press of the button, create new input controls; be it in javascript or server side, it makes no real difference.

How to swap two numbers using javascript function with one parameter

My Requirement is
I want to display this output when I gave a(0) the output should come 5 and when I gave a(5) the output should come 0.
a(0) = 5
a(5) = 0
like this
Hint:
Using this function
function A(num){}
like this
Please Help me how to do this I'm new in JS
Please give me different kind of solutions its more useful to my career.

function swap (input) {
if( input == 0)
return 5;
return 0;
}
i think there is no description needed

I think I see what you are getting at.
You want to input one variable into a function, and return another variable that is not defined yet. Then you want to define that variable by inputting it into the same function, and get the first input as the output. And so you should end up with 2 outputs.
Now this is technically impossible, because there are undefined variables at play. However, programming is about imagination and I think I have a solution (it's technically a hack but it will work):
var i = 1;
var output1;
var output2;
function swap(input) {
function func1(input) {
output2 = input;
i++;
}
function func2(input) {
output1 = input;
i = 1;
alert(String(output1) + "\n" + String(output2));
}
if (i === 1) {
func1(input);
}
else if (i === 2) {
func2(input);
}
}
while(true) {
swap(prompt("Enter your first input (this will be your second output):"));
swap(prompt("Enter your second input (this will be your first output):"));
}
The swap function goes back and forth between the values 1 and 2 in the variable i. That is how it keeps track of first or second inputs and their exact opposite outputs. The input, or parameter of the swap function is whatever the user types into the prompt boxes. Feel free to make it user-friendly, this is just the dirty code behind it. The reason they are outputted together is because the second input is undefined, and so the machine cannot guess what you were going to input. So first my little program collects all the data and just reverses the order when it is time to output. But to the user who knows nothing about JavaScript and what is going on underneath the hood, this would work perfectly in my opinion.
This should work for any data types inputted, I tested it myself with objects, strings, numbers, and arrays. Hope this helps!!

Shorter alternative to #mtizziani's answer:
let swap = x => !x * 5 // yes this is all
console.log(swap(0));
console.log(swap(5));
We toggle the input, so x is now 1 or 0
We multiple by 5.
Job done.

JavaScript - adding spaces after push in empty array & one checkbox is free

Here's my codepen:
https://codepen.io/CwittleZ/pen/vdzazO?editors=1010
When you click on the meat selection, it gets pushed into an array and then displayed, but there's no space between selections. How would I go about adding that space?
function meatSelected() {
var meat = [];
var meatChecked = document.querySelectorAll(
"input[name=meat_options]:checked"
);
for (var i = 0; i < meatChecked.length; i++) {
meat.push(meatChecked[i].value);
}
console.log(meat);
document.getElementById("meat").innerHTML = meat;
}
Also, I need one of the meats to be free, but anything over will be extra. I don't know how or where to add that 'if meat checked is > 1, all other meats will be an additional $1 each.' Is there somehow a way to access the function meatSelected for that purpose? I'm just starting out with JavaScript, so please no jQuery and simple terms if possible, even if it is a longer code. I just want to be able to understand why it works.
if (document.getElementById("pepperoni").checked) {
add += 1;
}
if (document.getElementById("sausage").checked) {
add += 1;
}
if (document.getElementById("canadian_bacon").checked) {
add += 1;
}
if (document.getElementById("ground_beef").checked) {
add += 1;
}
if (document.getElementById("anchovy").checked) {
add += 1;
}
if (document.getElementById("chicken").checked) {
add += 1;
}

The answer is in the line 83 in JavaScript part of your example. In line 77, you made an array of possible meats. Then, you just used this array and attached it to innerHTML as it is, so that the browser has to make it a string. Unfortunately, it doesn't care about spaces.
So, just change that line to this:
document.getElementById("meat").innerHTML = meat.join(", ");
It will use your already made array and convert it directly into string, with ", " between each of its children.
And to your second question, there are more possible solutions, I've implemented the easiest one in this codepen: https://codepen.io/anon/pen/ddqqyY?editors=1010.
Just sum up the number of already selected meats and if it's larger than zero, subtract 1 from your total.

I'd wrap each one of your selections in a "span", and add a margin after. You're using innerHTML, so you can just do it that way. It'll provide more flexibility than trying to style the plain-text.

document.getElementById("meat").innerHTML = meat.map(m => ` ${m}`);
here is your codepen that is modified https://codepen.io/jayas/pen/bLxjXo?editors=1010
edit as per suggestion
The ${m} together with the enclosing ticks `` used in the statement is called a template literal. Template literals can contain placeholders
and these are indicated by the dollar sign and curly braces ${}.
[].map(callBackFunc) used above is a method that creates a new array with each element being the result of the callback function.

If Else Statements in Javascript for LiveCycle

I am creating a form on Adobe LiveCycle that adds the numbers in different fields. I need to have the final field (Eligible Assets) add all the previous fields but exclude the sum of three of them and one in specific but only if it is greater than 60000. I've written the script as follows for the first part (to sum all the fields) this is in a field I've titled TotalAssets:
this.rawValue =Cash.rawValue+SavingsAccount.rawValue+ChildrensSavings.rawValue+CheckingAccount.rawValue+ValueHome1.rawValue+ValueHome2.rawValue+ValueVehicle1.rawValue+ValueVehicle2.rawValue+ValueVehicle3.rawValue+BusinessAccount.rawValue+BusinessAssets.rawValue+StocksBonds.rawValue+Retirement.rawValue+CDs.rawValue+OtherInvestments.rawValue+OtherAssets.rawValue;
This has worked fine, but the Retirement value if it is greater than 60000 should not be added into the calculation. This is what I've written (EligibleAssets):
if (Retirement.rawValue > 60000) {
Retirement.rawValue = 0;
} else {
Retirement.rawValue == Retirement.rawValue ;
}
this.rawValue = TotalAssets.rawValue - (ValueHome1.rawValue+ValueVehicle1.rawValue +Retirement.rawValue);
When I save the form as a PDF the first total of the fields calculates correctly but the second field comes up blank.
If you can spot what I'm missing or doing wrong I would really appreciate any feedback. Thank you!

There are two simple problems that I see here.
First problem is that you are using == when you should be using =.
== - check if the left side is equal to the right side. Example: if(x == 5) {
= - set the left side to the value of the right side. Example: x = 5
In the first example we leave x alone, but in the second example we change x to 5.
So your code should look like:
} else {
Retirement.rawValue = Retirement.rawValue;
}
However, when you think about this, this code doesn't actually do anything. Retirement.rawValue will not change.
This leads us to the second mistake in the code, at least, it looks to me like a mistake.
if(Retirement.rawValue > 60000) {
Retirement.rawValue = 0;
}
This actually changes Retirement.rawValue, which might potentially change what's inside the Retirement field of your form. Worse, its possible that the form would look the same, but act differently when some other field calculates, since you've changed its rawValue. That would be a very tough bug to catch.
The solution is to create a new variable: http://www.w3schools.com/js/js_variables.asp
So now we can create a new variable, set that variable to either the retirement amount or nothing, and then add that variable to the other rawValues at the end:
var retirementOrZero;
if(Retirement.rawValue > 60000) {
retirementOrZero = 0;
} else {
retirementOrZero = Retirement.rawValue;
}
this.rawValue = TotalAssets.rawValue - (ValueHome1.rawValue + ValueVehicle1.rawValue + retirementOrZero);
Now we have a number that we can name anything we want, and we can change it however we want, without affecting any code but our own. So we start by checking if our retirement value is greater than 60000. If it is greater, we set our variable to 0. Otherwise, we set our variable to the retirement value. Then we add that variable we made, to the home and value cost.
As a final question, is it supposed to do
if(Retirement.rawValue > 60000) {
retirementValueOrZero = 0;
}
or is it supposed to do
if(Retirement.rawValue > 60000) {
retirementValueOrZero = 60000;
}
Of course, if you are setting it to 60000 instead of setting it to zero, you probably want to name your variable cappedRetirementValue or something like that -- just make sure you rename it everywhere its used!
Hopefully that helps!
Edit: You said you're only adding retirement value if it is greater than 60k, so what you want is this:
if(RetirementValue.rawValue > 60000) {
retirementValueOrZero = RetirementValue.rawValue;
} else {
retirementValueOrZero = 0;
}

JavaScript logic - Parsing a textarea

I need to take a textbox that is full of formatted info about accounts and then sort it somehow. I would like to know if it would be ideal (I'm trying to make this as efficient as possible) to parse the info into a two dimensional array, or if I should make account objects that will hold info in fields.
The program is simply meant to format the data so that it can be printed out without having to copy/paste.
So far I have...
function generateOutputfvoc()
{
var accountLines = document.getElementById('accountLines').value;
var accountLinesTemp = accountLines.split(/[\s]/);
for(var i = 0; i < accountLinesTemp.length; i++)
{
if(accountLinesTemp[i].match(/
Edit (1-18-13): Here is an example input. It is basically text copied from a web CRM tool. Note, this example input is something I typed up randomly.
P8B000001234567 stackoverflow Thing 12522225555 444 Active 2005-02-26 CO1000123456
P8B000001234568 stackoverflow Another Thing 444 Active 2005-02-26 CO1000123456
P8B000001234569 stackoverflow Another Thing 556 Active 2005-02-26 CO1000123456
I would like my program to take the text and simply output the text like this:
P8B000001234567 stackoverflow Thing 12522225555 444 Active 2005-02-26 CO1000123456
P8B000001234568 stackoverflow Another Thing 444 Active 2005-02-26 CO1000123456
P8B000001234569 stackoverflow Another Thing 556 Active 2005-02-26 CO1000123456
Also, I would like to know if I should use jQuery variables. I asked this because I have been looking online a lot and I found examples that use code that looks like this:
$check=fcompcheck();
if($check)
{
$output=document.frm1.type.value+" / ";
$output=$output+"Something - "+document.frm1.disco.value+" / ";
Note the: $output variable. The dollar sign indicates a jQuery variable, right?
Thank you for any help you might be able to offer me.
Update (1-19-13): I've taken a shot at it, but I'm making slow progress. I'm used to programming Java and my JavaScript looks too similar, I can tell I'm makings errors.
I'm taking it one step at a time. Here is the logic I'm using now.
Person pastes text into text box and pushes the generate button
Program takes the contents of the text box and parses it into a large array, removing only whitespace
Program then searches for patterns in the text and begins passing values into variables
I am trying to get the program to simply identify the pattern "Summary section collapse Name" because these four words should always be in this sequence. Once it identifies this it will pass the next two array values into first and last name variables. Here's some of the code:
var contactNameFirst, contactNameLast;
// Parse the input box into an array
var inputArr = document.getElementById('inputBox').value.split(/[\s]/);
for(var i = 0; i < inputArr.length; i++)
{
if(inputArr[i] == "Summary" && inputArr[i - 1] == "section" && inputArr[i - 2] == "Collapse" && inputArr[i + 1] == "Name")
{
if(inputArr[i + 2] != "Details")
{
contactNameFirst = inputArr[i + 2];
}
else
{
contactNameFirst = "";
}
if(inputArr[i + 3] != "Details")
{
contactNameLast = inputArr[i + 3];
}
else
{
contactNameLast = "";
}
}
}
document.getElementById('contactNameOutput').innerHTML = contactNameFirst + " " + contactNameLast;
Also, should I create a new post for this now, or keep editing this one?

Your accountLinesTemp is an Array of String, you could use the Array.sort function to sort your array as expected, and then use Array.join to get the full String if necessary.
See https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Array/sort on MDN for more information.
