Question

What is the best way to solve the problem of Chrome auto-complete overlapping with labels in Vuetify?

When attempting to make a login form using outlined text fields in Vutify, there is an issue with Chrome autocomplete overlapping the labels.

<v-text-field
  v-model="email"
  label="e-mail"
  name="email"
  outlined
  prepend-icon="mdi-account"
  type="text"
  required
>
</v-text-field>

Answer №1

Here is how I resolved the issue at hand.

It appears that our primary difficulties are as follows:

The autofill feature in Chrome, upon page load, does not trigger interface reactivity, resulting in a design mismatch with your image.
Therefore, when injecting code, we must manually address this issue since Chrome does not provide an event to alert us of auto-filled login/password information.

Interestingly, any click performed by the user on the browser window automatically triggers reactivity and resolves all issues, but this does not occur through internal triggers or dispatches.

Firstly, we need to find a way to react after the autofill of login/password details. And secondly, we need to resolve the design on our own because only user actions can restore the design to its proper state.

1. Reacting after autofill on page load

Following Harkness' suggestion, we can periodically check :-webkit-autofill for a certain time interval after the code has been mounted to detect autofilling (this method worked well for Chrome/Firefox/Edge based on my testing).
Alternatively, we can utilize the animationstart event (refer to: https://github.com/material-components/material-components-web/issues/4447#issuecomment-580401216)

I opted for the first solution:

export default {
  //...
  data() {
    return {
      //...
      autofillFix: false,
    }
  },
  //...
  mounted() {
    this.autoLoginCheckingInterface()
  },
  //...
  autoLoginCheckingInterface() {
    // every 100ms, we check for the occurrence of the issue
    let intervalDetectAutofill = setInterval(() => {
      if (
        // selecting elements affected by autofill for checking
        document.querySelectorAll('input[type="password"]:-webkit-autofill')
          .length > 0
      ) {
        // signaling system about the issue if detected
        this.autofillFix = true

        // stopping further checks once issue is detected
        clearInterval(intervalDetectAutofill)
      }
    }, 100)

    // if no autofill occurs in 3s, stop checking
    setTimeout(() => {
      if (intervalDetectAutofill) {
        clearInterval(intervalDetectAutofill)
        intervalDetectAutofill = null
      }
    }, 3000)
  },
  //...
}

<!--
apply `.autofill-fix` class to handle design fix when issue arises
--> 
<v-text-field
      ...
      :class="{ 'autofill-fix': autofillFix }"
      ...
      label="Email address or username"
      ...
      dense
      outlined
      @focus="autofillFix = false"
/>
<!--
use @focus to revert to normal behavior as USER ACTION restores functionality
-->
<v-text-field
      ...
      :class="{ 'autofill-fix': autofillFix }"
      ...
      label="Password"
      type="password"
      ...
      dense
      outlined
      @focus="autofillFix = false"
/>

2. Addressing the design issues

We notice the changes in v-text-field appearance when filled. Initially, without content, it looks like this:

https://i.stack.imgur.com/b0377.png

After autofilling, it appears as shown below:

https://i.stack.imgur.com/odQuf.png

From the highlighted area, we can identify the specific CSS modifications needed to rectify the design flaw whenever the .autofill-fix class is present.

.autofill-fix.v-text-field--outlined.v-input--dense .v-label {
  left: -28px!important;
  transform: translateY(-16px) scale(.75);
}

Note: Modify the CSS selector according to your usage of outlined or dense. Pay attention to specificity of selectors . Adapt the fixes to suit your unique design needs.

Answer №2

One alternative approach is to implement a method suggested by @elazard here, which involves defining an autofill variable like so:

data () {
        return {
            login: null,
            password: null,
            autofill: false,
            intervalDetectAutofill: null
        }
    },

<v-text-field
    v-model="password"
    type="password"
    label="Password"
    :placeholder="autofill ? ` ` : null"
/>

Utilizing the solution provided by @adam-reis, the code within the mounted() lifecycle hook of the login page would appear as follows:

mounted () {
        // Check for autofill every 100ms
        this.intervalDetectAutofill = setInterval(() => {
            if (document.querySelectorAll("input[type=\"password\"]:-webkit-autofill").length > 0) {
                this.autofill = true
            }
        }, 100)

        // Clear interval after 3s if necessary
        setTimeout(() => {
            if (this.intervalDetectAutofill) {
                clearInterval(this.intervalDetectAutofill)
                this.intervalDetectAutofill = null
            }
        }, 3000)
    },

Additionally, it's essential to reset the autofill variable to false upon user input:

watch: {
        password () {
            this.autofill = false
        },
        autofill () {
            // Clear interval if autofill detected or user input occurs
            if (this.intervalDetectAutofill) {
                clearInterval(this.intervalDetectAutofill)
                this.intervalDetectAutofill = null
            }
        }
    },

Answer №3

I have managed to achieve a successful outcome with just a few lines of code that are very generic.

 mounted() {
    setTimeout(() => {
      const elements = document.querySelectorAll("input:-webkit-autofill")
      elements.forEach((element) => {
        const label = element.parentElement.querySelector("label")
        label.classList.add("v-label--active")
      })
    }, 500)
  },

If the browser autofills the v-text-field, this code will apply the "active" class to the Label. The appearance of the v-text-field will not be affected.

Answer №4

Here's a little trick I used to achieve this:

In the HTML code:

:placeholder="!autofilled ? ' ' : ''"

In the JavaScript file:

data() {
        return {
            form: {
                email: '',
                password: '',
            },
            error: null,
            autofilled: false,
        };
},
watch: {
    'form.email'() {
        this.autofilled = true;
     },
},

Explanation: By setting the placeholder to a blank space always, it causes the label to be raised. The downside is that if set statically, the label won't go back down even if you empty the input after filling it. So, I made the placeholder dynamic and only show a blank space before any change is made to the input; afterwards, the placeholder goes back to nothing. It's not perfect because on initial load before the user saves a password, the labels will be raised, but I haven't found a better solution yet.

When browsers utilize the autofill feature, they typically automatically populate the fields with values. However, in this scenario, the field label only moves out of the way once the input field is focused and remains hidden when it loses focus with a value present. Autofill does not trigger the focus event, causing the label to remain in its original position.

To correct this behavior, adjustments would need to be made within Vuetify.

Answer №6

To implement the functionality of lifting a label when the input is filled, you can assign an id to your input element and retrieve its value during component mounting. If the input is not empty, set your data value to match the input's value. It may be necessary to wait for the DOM to update before performing this check, which can be done using nextTick:

mounted()  {
  this.$nextTick(() => {
     const inputValue = document.getElementById('inputId').value;
     this.dataValue = inputValue || '';
  });
}
