RESOLVED - Save the data whit Control Valid

Hi,

I see a couple of things:

ImputValid ();
IF (validationForm === true) {

• validationForm is not declared (it's declared later in your code, but isn't available for the above code)

• IF should be if

What error (or errors) are you getting?

Hello Thanks for your reply,

actually gives me the error that the variable validationForm is undefine. How can I solve the problem?

I do not know how to return the value obtained from a function, as long as it can be done

Thank you

To return the value, just add the following line to the end of the InputValid() function:

return validationForm;

Then, you can use the value like this:

if (ImputValid() === true) {

You can read more about a returning a value in a function.

Good luck,

Yisrael

I tried to change the code as per your example, but it does not work, when I add return at the end of the function it always gives me the variable and undefine.

I tried in other ways looking at the guide but I could not

At the end, thanks to the guide I solved by doing a

return true;

ritun false;

directly from the function without using the variable

Thank you

Great! You return true; and return false: is perfect.

I messed up in my answer to you regarding the declaration of validationForm.

Let me explain with a simple example:

function ImputValid() {
    let ImputValid_01 = $w("#ImptData").valid;
    if (  (ImputValid_01 === true) {
        // validationForm declared here and only available inside { }
	let validationForm = true;
    } else {
        // another different validationForm is declared here
	let validationForm = false;
    }

    // we can't "see" either of the validationForm declarations above
    return validationForm; // this does NOT work
}

This is what you need:

function ImputValid() {
    let ImputValid_01 = $w("#ImptData").valid;
    let validationForm; // declare validationForm
    if (  (ImputValid_01 === true) {
        // do NOT declare validationForm here (no let)
	validationForm = true;
    } else {
        // do NOT declare validationForm here (no let)
	validationForm = false;
    }

    // we can now "see" declaration of validationForm above
    return validationForm; // this does NOT work
}

See more on let, including a playground to try it out.

I hope this helps.

Ok but if I do like your example if it should be set like this

ImputValid ();

IF (validationForm === true) {

and not so

if (ImputValid () === true) {

Is what I'm saying correct?

Thank you

Since in my example, the ImputValid() function returns a value, it can be used like this:

if (ImputValid () === true) {

or like this:

let validValue = ImputValid();
if (validValue === true) {

Both ways are equivalent. The function ImputValid() returns a value, and can be used directly (first example), or can be assigned to a variable (second example).

Thank you so much for the explanation,

I am still testing to learn this better.

Thank you and have a good day

Good job! I think you'll get a lot out of the investement that you're making learning this material.

Remember me when you're rich and famous. 🙃

Surely I will remember you, they are all information that opens up a world that fascinates me.

Thank you so much
