Error TS2339 - Property 'rows' does not exist on type HTMLElement when looping through table in Angular 7

Encountering error when trying to loop through HTML table in Angular 7

Currently working with Angular 7 and facing an error while looping through a table in the HTML code

ERROR in src/app/Pages/part-compare/part-compare.component.ts(25,38):

error TS2339: Property 'rows' does not exist on type 'HTMLElement'.

src/app/Pages/part-compare/part-compare.component.ts(27,26): error TS2339:

Property 'rows' does not exist on type 'HTMLElement'.

Need help solving this error. Any suggestions?

Things I have attempted:

var table = document.getElementById("CompareParts");
    for (var i = 1, row; row = table.rows[i]; i++) {
      for (var j = 0, col; col = row.cells[j]; j++) {
        var Cell = table.rows[i].cells
        this.ACells.push(Cell);
      }
    }
    this.length=this.ACells.length
    for (var x = 0; x < this.ACells.length; x++) {
      this.ARows.push(this.ACells[x]);

Answer №1

If you use document.getElementById in TypeScript, the specific type of the element is not known, so the function defaults to returning the generic type HTMLElement. To specify the type as HTMLTableElement, you should cast it accordingly.

You can try code like this:

var table = document.getElementById("CompareParts") as HTMLTableElement;
