What HTML tag is used to define the maximum length and number of lines for text content?

Seeking advice on how to set the maximum length of a line and the maximum number of lines. Should I use a specific element for this task, or would it be better to implement it in TypeScript?

Answer №1

If you want to include a text area that spans multiple lines, utilize the HTML tag and adjust the size using the cols and rows attributes.

Consider implementing a custom validator to limit the maximum number of characters per line in the text area.

<textarea siInput [(ngModel)]="myTextarea" style="resize:none;  white-space: both;" rows="20" (keyup)="onKeyAction()"(keydown)="onKeyAction()" id="textID" maxlength="{{maxTextAreaLength}}"></textarea>


myTextarea;
maxTextLineLength = 10;

onKeyAction() {
if (this.myTextarea) {
  var lines = this.myTextarea.split(/(\r\n|\n|\r)/gm);
  for (var i = 0; i < lines.length; i++) {
    if (lines[i].length >= this.maxTextLineLength) {
      lines[i] = lines[i].substring(0, this.maxTextLineLength);
    }
  }
  this.myTextarea = lines.join('');
 }
}
