vue wants to enter numbers in the input box, and DOM loops out the number of input numbers
simple layout code
<input type="number" v-model="desc" value="desc">
<h1 v-for="(item,index) of desc" :key="index">
{{ msg }}
</h1>data data. 5
is passed by default. msg: "Wel",
desc: 5 page shows 5 normal dom
desc.length
so I would like to ask the boss if you need to change it or not, if the description is not clear enough, you can comment and leave a message. Thank you!
of = > in
<h1 v-for="(item,index) in +desc">
{{ msg }}
</h1>
to put it this way, the value obtained by input does not seem to be correct. It is of the type of string. Just convert it in the loop.
