How to use Vue to implement password visible switching effects
How to use Vue to implement the password visible switching effect
Password visible switching is a common user experience optimization function that allows users to choose whether to visible or not when entering a password, which is convenient The user confirms whether the input is correct or not. In Vue, we can achieve password visible switching effects by using data binding and conditional rendering. This article will introduce how to use Vue to implement password visibility switching effects, and provide specific code examples.
Implementation idea:
- Use Vue's two-way data binding to bind the password entered by the user with the data attribute in the Vue instance through v-model.
- Use Vue's conditional rendering to control whether the password is visible or not through the v-show or v-if instructions.
- Switch the password between visible and invisible, trigger the method in the Vue instance or modify the value of the data attribute through the click event or the change event of the check box.
The following is a sample code that uses Vue to implement the password visible switching effect:
<template>
<div>
<input type="password" v-model="password" placeholder="请输入密码">
<input type="checkbox" v-model="visible" @change="toggleVisible">
<label>显示密码</label>
<br>
<input v-if="visible" :type="showPassword ? 'text' : 'password'" :value="password">
<input v-else type="password" :value="password">
</div>
</template>
<script>
export default {
data() {
return {
password: '',
visible: false,
showPassword: false
};
},
methods: {
toggleVisible() {
this.showPassword = !this.showPassword;
}
}
};
</script>In the above code, we first define a password input box and a check box, through The v-model directive bidirectionally binds the value of the password input box to the password attribute of the Vue instance, and bidirectionally binds the value of the check box to the visible attribute of the Vue instance.
Then, we use the v-if directive to determine whether to display the password, and decide whether to display the "Show Password" or "Hide Password" text based on the value of the visible attribute. When the user changes the value of the check box, the toggleVisible method will be triggered, which will change the value of the showPassword attribute, thereby switching the password between visible and invisible.
Finally, the input type of the password box is determined based on the value of the showPassword attribute. If showPassword is true, the input type is set to text, which is the visible state; otherwise, it is set to password, which is the invisible state.
In the above code example, the function of switching the password between visible and invisible through the check box is implemented. You can also modify the code according to actual needs, such as using buttons or other interactive methods to implement switching functions.
Summary:
Using Vue to implement password visible switching effects is a simple and effective way to enhance the user experience. Through data binding and conditional rendering, you can easily switch between visible and invisible passwords, allowing users to choose whether to visible passwords according to their needs. The above is a sample code that uses Vue to implement the password visible switching effect. I hope it will be helpful for you to understand and learn Vue.

How to use PHP to implement AI content recommendation system PHP intelligent content distribution mechanism
Jul 23, 2025 pm 06:12 PM
1. PHP mainly undertakes data collection, API communication, business rule processing, cache optimization and recommendation display in the AI content recommendation system, rather than directly performing complex model training; 2. The system collects user behavior and content data through PHP, calls back-end AI services (such as Python models) to obtain recommendation results, and uses Redis cache to improve performance; 3. Basic recommendation algorithms such as collaborative filtering or content similarity can implement lightweight logic in PHP, but large-scale computing still depends on professional AI services; 4. Optimization needs to pay attention to real-time, cold start, diversity and feedback closed loop, and challenges include high concurrency performance, model update stability, data compliance and recommendation interpretability. PHP needs to work together to build stable information, database and front-end.
How to develop AI intelligent form system with PHP PHP intelligent form design and analysis
Jul 25, 2025 pm 05:54 PM
When choosing a suitable PHP framework, you need to consider comprehensively according to project needs: Laravel is suitable for rapid development and provides EloquentORM and Blade template engines, which are convenient for database operation and dynamic form rendering; Symfony is more flexible and suitable for complex systems; CodeIgniter is lightweight and suitable for simple applications with high performance requirements. 2. To ensure the accuracy of AI models, we need to start with high-quality data training, reasonable selection of evaluation indicators (such as accuracy, recall, F1 value), regular performance evaluation and model tuning, and ensure code quality through unit testing and integration testing, while continuously monitoring the input data to prevent data drift. 3. Many measures are required to protect user privacy: encrypt and store sensitive data (such as AES
