How to use v-if in vuejs - Stack Overflow

javascript php vue.js

I just started to connect to vuejs, and now there is a problem like this. I want to realize that the data in a table is ordinary text data when viewed. Once the edit button of each row is clicked, the data of this row is displayed in the input input box. Implementation,
My initial idea is this: add an editmode attribute to the data of this column, once the edit button is clicked, change the editmode to true, and then v-if determines the output style based on this value:

<code><table class="table table-bordered">
                    <thead>
                        <tr>
                            <th>id</th>
                            <th>name</th>
                            <th>pass</th>
                            <th>操作</th>
                        </tr>
                    </thead>
                    <tbody>
                        <template v-for="data in apidata" track-by="$index">
                            <tr>
                                <td>{{$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.name"></div>
                                    <div v-else>{{data.name}}</div>
                                </div>
                                </td>
                                <td>
                                    <button v-on:click="remove($index)" class="btn btn-danger">删除</button>
                                    <button v-on:click="edit(data)" class="btn btn-danger">编辑</button>
                                </td>
                            </tr>
                        </template>
                    </tbody>
                </table></code>

Then in the method

<code>            edit: function(data){
                //alert(data.editmode);
                data.editmode = true;
            }</code>
Copy after login
Copy after login

I can see that every time I do this, the editmode does change to true, but that row of data does not change to the input mode. I would like to ask for advice on how to implement it.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
