Data is not properly displayed in VueJS

问题

I have a small problem with my VueJS code, in the section "Output : Compressed GS1 Digital Link URI"

When there is no result, it should have nothing display like this (I have removed manually) :

I think I should put an if statement and only display the result if there is something. Here is my code :

<input id="uncompressedDigitalLinkInput" class="digitalLink" type="text" v-model="uncompressedDigitalLinkInput">
<td class="charCount">{{uncompressedDigitalLinkInput.length}}</td>

What do you think ?

Thanks for your help :)
