[Vuejs]-How do I use v-if statement to show static image in vuejs

If you want to use v-if specifically then you don’t need to use ternary operator. You can try this way to show default image using v-if and v-else.

<img v-if="sub_section && sub_section.imageURL" :src="sub_section.imageURL" alt="uploaded-image">
<img v-else src="@/assets/images/upload.png"  alt="default-image">

Here, in the above code, if you get something in sub_section and imageURL both then v-if block will be executed, or else default image will be shown by executing v-else block.

You need to make sure that you apply condition for both sub_section and imageURL because there’s a possibility that you might not get anything in the first variable sub_section itself, which might throw an error if you would be directly using sub_section.imageURL in the condition.
