Javascript Vue 3 Extract data from an array and display into a table-CodePudding

Hello everyone hope you having a great day,

I have setup a front end app on Vue Js linked with an express.js api which connects to a mysql database. I use axios for sending http requests. I am able to grab the data from my mysql database and console.log it into the front end system. However I am struggling to extract the data from the array and display it into the table.

This is the table.

            <table >
            <thead>
                <tr>
                    <th scope="col">#ID</th>
                    <th scope="col">First</th>
                    <th scope="col">Last</th>
                    <th scope="col">email</th>
                    <th scope="col">DOB</th>
                    <th scope="col">Country Of Residence</th>
                    <th scope="col">Phone Number</th>
                    <th scope="col">Contact_Via Phone</th>
                    <th scope="col">Contact Via Email</th>
                    <th scope="col">Contact Via Mail</th>
                    <th scope="col">Sign up date</th>
                </tr>
            </thead>
            <tbody>
                <tr>
                <th scope="row" v-for="name in newData" :key="newData.id"></th>
                <td>Mark</td>
                <td>Otto</td>
                <td>@mdo</td>
                </tr>
                <tr>
                <th scope="row">2</th>
                <td>Jacob</td>
                <td>Thornton</td>
                <td>@fat</td>
                </tr>
                <tr>
                <th scope="row">3</th>
                <td colspan="2">Larry the Bird</td>
                <td>@twitter</td>
                </tr>
            </tbody>
            </table>

This is where I grab the data from the database when the page is created.

    async created() {
        
        try {
            const getUserData = await axios.get('/api/getstudentdata',  {})
            .then(getUserData => getUserData.data)
            {
                this.newData = JSON.parse(JSON.stringify(getUserData))
                for( let i = 0; i < this.newData.length; i  ) {
                    console.log(this.newData[i].Name)
                }
            }
        }catch(error) {
            console.log(error)
        }
    },

Here I have added what my console logs and what the vue dev tools say. https://imgur.com/a/eIHDq6u console logs:

CodePudding user response：

First of all, in a v-for loop, keys must be unique and newData.id is not a valid key, I guess you wanted to use something like:

v-for="item in newData" :key="item.id"

Secondly ,you're using v-for in the wrong place and you are not using vue mustaches to use dynamic variables. Try this one:

<tr v-for="item in newData" :key="item.id">
  <td>{{item.ID}}</td>
  <td>{{item.Name}}</td>
  <td>{{item.Surname}}</td>
  ...
 </tr>
