Hello Everyone,
I simply want a drop downs selection to enable or disable an input field. There are only two selections and one has the value of 1 and the other has the value of 0. Here is my code below, I know I am close but it is not working yet. Any help would be greatly appreciated.
export function dropdown3_change(){ if ($w("#dropdown3").value === 1){ $w("#input1").enable(); } else { $w("#input1").disable(); } }
Thank you!
It will not work, because you compare apple with bannana. 😁
You compare STRING with NUMBER, this is not possible.
There are 2 solutions for this.
1) you make it the lazy way, like i did ----> replace ---> === with ---> ==
2) transform STRING into NUMBER, or NUMBER into STRING
How do i know this?
console.log(typeof $w('#dropdown3').value) console.log(typeof 1)
Add this to your CODE.
Press F-12 in your google-web-browser and go to CONSOLE.
Look at the results, what do you see? ? ? (do not forget to publish site first !)
Or do it in your Wix-Editor-Console, look at the results at the bottom of your screen in the console-terminal.
How to fix it?
1) Convert NUMBER into STRING:
let newValue = 1 console.log(typeof newValue) let newValue = (1).toString() console.log(typeof newValue)
2) Convert STRING into NUMBER:
let newValue = "1" console.log(typeof newValue) let newValue = Number("1") console.log(typeof newValue)
The LAZY-SOLUTION 😁
export function dropdown3_change(){ if ($w("#dropdown3").value == 1){ $w("#input1").enable(); } else {$w("#input1").disable();} }
This is the code I tried, but not sure why it isn't working
export function dropdown3_change(event) { ($w('#dropdown3').value) if ($w('#dropdown3').value===1) { $w('#input1').enable()} else {$w('#input1').disable()} }
Thank you for sending the link, but still can't figure it out.
