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:

1. 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.
2. Use Vue's conditional rendering to control whether the password is visible or not through the v-show or v-if instructions.
3. 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.
