Make Input Type=“Password” Use Number Pad on Mobil

问题:

On my site designed for mobile devices I have an input field that is used for PIN numbers. I want the text to be hidden as it is entered and I want the number pad to pop up when the user on the mobile device wants to enter the PIN. The number pad pops up when Type="Number" but not when Type="Password" and I can't (Or don't know how to) set Type="Number and Password".

Any Ideas?

Thanks in advance!

回答1:

Some browsers (iOS) recognize the specific pattern attribute value of [0-9]* as triggering numeric keypad.

The HTML 5.1 draft contains the inputmode attribute, which has been designed to address the specific issue of input mode (like key pad) selection, but it has not been implemented yet.

You could use it for the future, though – even though the current HTML 5.1 does not allow it for type=password, for some odd reason.

<input type="password" pattern="[0-9]*" inputmode="numeric">

Finally, I found an answer here:

input[type=number] {
    -webkit-text-security: disc;
}

(only works in WebKit based browsers)

The straightforward ways like using "pattern" and "inputmode" not working in Android nor IOS, so I emplemented the below workaround using CSS, and JavaScript.

HTML

 <div>
  <input type="password" class="form-control ng-valid-minlength ng-valid-pattern ng-dirty ng-valid ng-valid-required" id="pass" name="pass" data-ng-minlength="4" maxlength="4"  tabindex="-1">
  <input type="tel" class="form-control ng-valid-minlength ng-dirty ng-valid ng-valid-required" id="passReal" name="passReal" required="" data-ng-minlength="4" maxlength="4" data-display-error-onblur="" data-number-mask="telephone"
         tabindex="5">
</div>

JavaScript

$().ready(function(){
var xTriggered = 0;
$( "#passReal" ).keyup(function( event ) {
  $('#pass').val($('#passReal').val());
  console.log( event );
});
$( "#pass" ).focus(function() {
  $('#passReal').focus();
});

  });

Style:

input#passReal{
  width:1px;
  height:10px;
}
input#pass {
    position: absolute;
left:0px;
}

or you could create your own keyboard with javascript and CSS, and when the user type a number, bisplay * and store the value in a javascript variable. Just lik I did and it makes user login very smooth and easy... Mobile first
