Topic: mdbCharCounter and length doesn't work into contenteditable Table

ariful free asked 2 years ago

Hi! I would like to add mdbCharCounter and length into contenteditable Table. But it's don't work. Also I want to change the editable column style like input/textarea field.

 <td class="green lighten-5 w-80">
                            <span type="text" length="36" mdbCharCounter contenteditable="true"
                                (keyup)="changeValue(id, 'swiftValue',  $event)"
                                (blur)="updateList(id, 'swiftValue',  $event)"
                                [textContent]="el.swiftValue"></span>
                        </td>

It's showing this error below: ERROR TypeError: Cannot read properties of undefined (reading 'length') at CharCounterDirective.onKeyUp (ng-uikit-pro-standard.js:15964) at CharCounterDirective.show (ng-uikit-pro-standard.js:15976) at CharCounterDirective_focus_HostBindingHandler (ng-uikit-pro-standard.js:15982) at executeListenerWithErrorHandling (core.js:15213) at wrapListenerIn_markDirtyAndPreventDefault (core.js:15248) at HTMLSpanElement.

Please insert min. 20 characters.

@ariful This directive will not work with a span element because under the hood it tries to read properties that are not available on this element.

Edit, added a simple custom solution:

<span
  #span
  (keyup)="span.textContent.length = $event.target.value.length"
  contenteditable="true"
  style="width: 100px; height: 20px; background-color: gray"
>test</span>

<span>{{ span.textContent.length }} / 36</span>

@Arkadiusz Idzikowski Thanks for your replay. I must have to do this on my application, What's the alternative solution? Please help me.

@ariful We currently don't plan to adjust this directive for other HTML elements, you would need to use a custom solution. I added a simple example to my answer, you can adjust it to your needs and store the elements length in variables, then update the variables on keyup event change.
