I have a function written in TypeScript:
// Form
summaryAreaForm = new FormGroup ({
summary: new FormControl(null)
})
// Function
update() {
document.getElementById('textDiv').innerHTML = this.summaryAreaForm('summary').value;
}
When I try to access
this.summaryAreaForm('summary').valueCannot invoke an expression whose type lacks a call signature. Type 'FormGroup' has no compatible call signatures.It is not recommended to use document.getElementById or similar methods in angular development.
A better approach to solving this problem would be:
this.summaryAreaForm.get('summary').value;I am looking to create a grid on the screen of a web browser or mobile device, with each grid item containing just one letter. It's similar to a crossword puzzle, but taking up most of the screen. I've tried using divs for this purpose, but it se ...
