我很难检测Firefox中的自动填充。这是唯一对我有用的解决方案:
演示版
HTML:
<div class="inputFields">
<div class="f_o">
<div class="field_set">
<label class="phold">User</label>
<input type="tel" class="form_field " autocomplete="off" value="" maxlength="50">
</div>
</div>
<div class="f_o">
<div class="field_set">
<label class="phold">Password</label>
<input type="password" class="form_field " autocomplete="off" value="" maxlength="50">
</div>
</div>
</div>
CSS:
/* Detect autofill for Chrome */
.inputFields input:-webkit-autofill {
animation-name: onAutoFillStart;
transition: background-color 50000s ease-in-out 0s;
}
.inputFields input:not(:-webkit-autofill) {
animation-name: onAutoFillCancel;
}
@keyframes onAutoFillStart {
}
@keyframes onAutoFillCancel {
}
.inputFields {
max-width: 414px;
}
.field_set .phold{
display: inline-block;
position: absolute;
font-size: 14px;
color: #848484;
-webkit-transform: translate3d(0,8px,0);
-ms-transform: translate3d(0,8px,0);
transform: translate3d(0,8px,0);
-webkit-transition: all 200ms ease-out;
transition: all 200ms ease-out;
background-color: transparent;
-webkit-backface-visibility: hidden;
backface-visibility: hidden;
margin-left: 8px;
z-index: 1;

pointer-events: none;
}
.field_set .phold_active {
font-size: 12px;
-webkit-transform: translate3d(0,-8px,0);
-ms-transform: translate3d(0,-8px,0);
transform: translate3d(0,-8px,0);
background-color: #FFF;
padding-left: 3px;
padding-right: 3px;
}
.field_set input[type='text'], .field_set select, .field_set input[type='tel'], .field_set input[type='password'] {
height: 36px;
}
.field_set input[type='text'], .field_set input[type='tel'], .field_set input[type='password'], .field_set select, .field_set textarea {
box-sizing: border-box;
width: 100%;
padding: 5px;
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
border: 1px solid #ababab;
border-radius: 0;
}
.field_set {
margin-bottom: 10px;
position: relative;
}
.inputFields .f_o {
width: 100%;
line-height: 1.42857143;
float: none;
}
JavaScript:
// detect auto-fill when page is loading
$(window).on('load', function() {
// for sign in forms when the user name and password are filled by browser
getAutofill('.inputFields');
});
function getAutofill(parentClass) {
if ($(parentClass + ' .form_field').length > 0) {
var formInput = $(parentClass + ' .form_field');
formInput.each(function(){
// for Chrome: $(this).css('animation-name') == 'onAutoFillStart'
// for Firefox: $(this).val() != ''
if ($(this).css('animation-name') == 'onAutoFillStart' || $(this).val() != '') {
$(this).siblings('.phold').addClass('phold_active');
} else {
$(this).siblings('.phold').removeClass('phold_active');
}
});
}
}
$(document).ready(function(){
$(document).on('click','.phold',function(){
$(this).siblings('input, textarea').focus();
});
$(document).on('focus','.form_field', function(){
$(this).siblings('.phold').addClass('phold_active');
});
// blur for Chrome and change for Firefox
$(document).on('blur change','.form_field', function(){
var $this = $(this);
if ($this.val().length == 0) {
$(this).siblings('.phold').removeClass('phold_active');
} else {
$(this).siblings('.phold').addClass('phold_active');
}
});
// case when form is reloaded due to errors
if ($('.form_field').length > 0) {
var formInput = $('.form_field');
formInput.each(function(){
if ($(this).val() != '') {
$(this).siblings('.phold').addClass('phold_active');
} else {
$(this).siblings('.phold').removeClass('phold_active');
}
});
}
});
对于Chrome,我使用: if ($(this).css('animation-name') == 'onAutoFillStart')
对于Firefox: if ($(this).val() != '')
