Question

i m just learn vue.js and i want to display a table data.my opinion is when display mode the table just show. and when i click edit button of the line of the table, i want this line convert to model.

this is my code: ```

<table class="table table-bordered">
    <thead>
        <tr>
            <th>id</th>
            <th>name</th>
            <th>pass</th>
            <th>action</th>
        </tr>
    </thead>
    <tbody>
        <template v-for="data in apidata" track-by="$index">
            <tr>
                <td>{{$index + 1}}</td>
                <td>
                    <div v-show="data.editmode"><input v-model="data.name"></div>
                    <div v-else>{{data.name}}</div>
                </td>
                <td>
                    <div v-if=data.editmode><input v-model="data.name"></div>
                    <div v-else>{{data.name}}</div>
                </div>
                </td>
                <td>
                    <button v-on:click="remove($index)" class="btn btn-danger">remove</button>
                    <button v-on:click="edit(data)" class="btn btn-danger">edit</button>
                </td>
            </tr>
        </template>
    </tbody>
</table>

```
my data is like this

    [{name:'test', pass:'1'}, {name:'test2', pass:'2'}]

i bind a edit()function to listen the click event.
    edit: function(data){
                alert(data.editmode);
                data.editmode = true;
            }

i think when i click .becuase the data.editmode will change to true. this line will convert to input mode . but its useless. i have tried v-if=data.editmode , v-if="data.editmode" ,v-show="data.editmode" , still got nothing i dnt know why?

Solution

You just need to include editmode in your data declaration so that it is a reactive data item.

new Vue({
  el: 'body',
  data: {
    apidata: [{
      name: 'test',
      pass: '1',
      editmode: false
    }, {
      name: 'test2',
      pass: '2',
      editmode: false
    }]
  },
  methods: {
    edit: function(data) {
      data.editmode = !data.editmode;
    }
  }
});

    <tr>
      <th>id</th>
      <th>name</th>
      <th>pass</th>
      <th>action</th>
    </tr>
  </thead>
  <tbody>
    <tr v-for="data in apidata">
      <td>{{$index + 1}}</td>
      <td>
        <div v-if="data.editmode">
          <input v-model="data.name">
        </div>
        <div v-else>{{data.name}}</div>
      </td>
      <td>
        <div v-if=data.editmode>
          <input v-model="data.pass">
        </div>
        <div v-else>{{data.pass}}</div>
      </td>
      <td>
        <button v-on:click="remove($index)" class="btn btn-danger">remove</button>
        <button v-on:click="edit(data)" class="btn btn-danger">edit</button>
      </td>
    </tr>
  </tbody>
