Hey guys, I am new to Ionic 4, after I created my first project, I followed the steps of the tutorial. And He deleted the project structure by building up a new HTML file and Javascript file to show it is still runnable. However, when I created exactly the same .js file as what he simply did at 1:37:00 in the video.
`
const usrnmInput = document.querySelector(’#input-usrnm’);
const pswrdInput = document.querySelector(’#input-pswrd’);
const signupBtn = document.querySelector(’#btn-signup’);
const loginBtn = document.querySelector(’#btn-login’);
loginBtn.addEventListener(‘click’, () => {
const enteredUsrnm = usrnmInput.value;
const enteredPswrd = pswrdInput.value;
if(
enteredUsrnm.trim().length <= 0 ||
enteredPswrd.trim().length <= 0
){
return;
}
console.log(enteredUsrnm, enteredPswrd);
});` Then when I try to run in the chrome inspect tool, I couldn’t get the log message that wrote in this js file. and it pops me the error message that Uncaught ReferenceError: the document is not defined.
Do you guys know how could I fix this? I guess I shouldn’t create a Js file and should write it inside home.page.ts but I don’t know what it is and can’t start on it, and the tutorial didn’t cover much about it. Can someone please help me with this? Thank you so much!
