Adding two "Input" values

Discussion Ask a question
,

I have created two input cells on a page called “square2V” and “teamA”. Both are set to be numerical values.
When I multiply the two cells using the code below, it successfully multiplies the values and labels a button called “teamAScore” with this value.

$w("#teamAScore").label = ($w("#square2V").value * $w("#teamA").value).toString();

However, when I try to add the two cells by changing the * to a +, it adds them as text.
eg. 30 + 40 = 3040

Is it possible to add the two values as numbers.
Thanks

hey
you have to make the script think of them as numbers not strings.

+num1 + +num2;

adding the unary + before is a quick solution.

Hey,
You can also use the function parseInt before adding them.

Good luck,
Tal.

Thanks both! The +num1 + +num2 method worked!

Hi guys.
I have a quoteDate field in the collection.
I want to add a number of days to that date to show ad deadlineDate.

How do I add numbers to a date value in the data.js file?

Here it what I use:

$w.onReady( function () {

$w(‘#Calculate1’).onClick( function () {

console.log(“button has been pressed”)

$w(‘#totalmonths1’).value = $w(‘#convertyrs1’).value + $w(‘#Month1’).value

console.log(“calculation finished”)

})

})

it works but only combines the values instead of add the values. example: input1 = 12 input2 = 1
the above code returns the value 121 instead of 13 (12+1)

above vaguely referenced:

+num1 + +num2;
adding the unary + before is a quick solution.

or

use the function parseInt before adding them.

But it is not enough information to understand what changes need to be made.

I believe I need a code that will recognize the values as a number instead of a string but i am not certain .

Change this

$w(’ #totalmonths1 ‘).value = $w(’ #convertyrs1 ‘).value + $w(’ #Month1 ').value

To this

Let first = $w(’ #convertyrs1 ‘).value;
Let second = $w(’ #Month1 ‘).value;
$w(’ #totalmonths1 ').value = first+second

i am getting a “parsing” error for the words first and second. Not sure why or how to fix it.

Lowercase, Change Let to let

Thanks for helping me get through this Mike!

i used:

$w(‘#totalmonths1’).value = “” + (Number($w(‘#Years1’).value) *12 + Number($w(‘#Month1’).value));

and it works so far! it has added the two user input values successfully

@shaneicewilliams @mikemoynihan99 Hello, thank you so much for the calculation code! I was able to get my calculations to work properly thanks to both of you, but now how do you get the calculated value inserted into the database? I have tried to connect the element input to the database, and have tried to add a submit button, but the collection field is still empty. The calculations shows up on the page inside the correct element input box “fbTotal” , but even though its linked to the collection, it doesn’t export or show up. I need that number in there so I can display that total on a different page on my website. Please help and thank you!

Here’s my code:

$w.onReady( function () {

$w(‘#Calculate1’).onClick( function () {
console.log(“button has been pressed”)
$w(‘# fbTotal ‘).value = “” + (Number($w(’#dropdown1’).value) + Number($w(‘#dropdown2’).value) + Number($w(‘#dropdown3’).value) + Number($w(‘#dropdown4’).value) + Number($w(‘#dropdown5’).value) + Number($w(‘#dropdown6’).value) + Number($w(‘#dropdown7’).value));

console.log(“calculation finished”)
})
})
