It seems like a simple task, but I am looking for a solution without using jQuery.
I have the Id of a specific radio button control that I need to set. I tried the following code:
let radiobutton = document.getElementById("Standard");
radiobutton.checked = true;
Although I found similar examples online, when using Typescript/Javascript, I encounter the error message: "Property 'checked' does not exist on type 'HTMLElement'"
Do you have any suggestions?
I appreciate your assistance.
Try utilizing @ViewChild and template variables instead of using document.getElementById. Below is an illustration:
HTML:
<input #checkbox1 type="checkbox" [checked]="true" (change)="onChange(1, checkbox1)"/>{{name1}}
<br>
<input #checkbox2 type="checkbox" (change)="onChange(2, checkbox2)"/>{{name2}}
Typescript:
name1 = 'Angular 2';
name2 = 'Angular 4';
@ViewChild("input1") input1;
@ViewChild("input2") input2;
ngOnInit(){
this.input1.checked = true;
console.log("Checkbox1 is checked - ", this.input1.checked);
console.log("Checkbox2 is checked - ", this.input2.checked);
}
onChange(checkbox, item){
console.log("Checkbox%d was checked", checkbox);
console.log("Checkbox%d is checked - ",checkbox, item.checked);
}
