Hi Wix Code community,
I’m trying to add an a conditional to check if in the input field the user wrote an a lowercase letter and show a message at the user with the mistake to can change it.
This is the code that i have till the moment but i want add a “Else if” with the new condition.

$w.onReady( function () {
$w(“#input1”).onCustomValidation( (value, reject) => {
if ((value.length > 1) & (value.length < 12) ) {
reject(“BMX is invalid”);
$w(‘#text8’).show();
} else if (value === “BMXDOI007985”) {
reject(“BMX is invalid”);
$w(‘#text9’).show();
}

else {
$w(‘#text8’).hide();
$w(‘#text9’).hide();
}
});
});

Any advice is GREATLY appreciated!

Does the following work for you:

else if (/[a-z]/.test(value)) {
     reject("Lowercase letters are not allowed in BMX.");
     $w('#text9').show(); 
}

?

Thank you very much! It works perfect.
Have a excellent day!

You as well.

BTW, I recommend that you replace generic names like #input1 , #text8 , and #text9 with meaningful/mnemonic names; it makes your code easier to maintain (read/understand/debug).

Hi @abergquist
Can you help me again? I’m trying to use this condition into my .onCustomValidation

if( !value.endsWith(“@wix1.com” || “@wix2.com”))

And also i already tried with

if( !value.endsWith(“@wix1.com”) || !value.endsWith (“@wix2.com”))

But it does’n work, any advice is GREATLY appreciated!

Hi, Fernando.

I believe the following is what you want:

if ( !(value.endsWith("@wix1.com") || value.endsWith ("@wix2.com") )

To understand the above, read it from the inside out (as in "First determine if the value ends with “@wix1.com” or “@wix2.com”; then negate that logical/boolean condition and use that negated condition as the expression for the if statement).
