Question

我尝试将密码输入符号更改为其他符号。我成功地做到了，但要清理这个领域。我应该在网站上使用我的清除按钮，而不是删除键盘上的键。我想修复它，以便通过单击键盘上的删除来删除我的隐藏输入值。不清楚按钮。这是我在codepen上的代码：http://codepen.io/abomostafacobra/pen/QKWgJE

<h1>Changing Password Security Symbol</h1>
<input type="text"/>
<input type="hidden"/>
<button class="post">Post</button>
<button class="clear">Clear</button>
<span>Whin you write a wrong password Clear it by clicking Clear botton here not by delete key in your keyboard</span>
<div></div>

jquery

$('input').on('keyup',function(){
var string =
    $('input[type=text]').val();

$('input[type=hidden]')
    .val(
    $('input[type=hidden]').val() + 
    string.charAt(string.length - 1)
);
$('input[type=text]')
    .val(
        $('input[type=text]')
            .val().replace(/[^]/g,'@')
        );
})
$('.post').click(function(){
$('div').append('<b>' + $('input[type=hidden]').val() + '</b>')
})
$('.clear').click(function(){
$('div').empty();
$('input[type=text]').val('');
$('input[type=hidden]').val('');
})

Answer 1

在jquery中添加此代码

$('html').keyup(function(e){
    if(e.keyCode == 46) {
        //alert('Delete Key Pressed');
        $('div').empty();
    $('input[type=text]').val('');
    $('input[type=hidden]').val('');
    }
});
