javascript - 启用/禁用虚拟键盘

Question

我正在使用 virtual keyboard .我有一个复选框来控制是否显示虚拟键盘。问题是我不明白如何禁用它。我尝试解除绑定(bind)但它不起作用...

我还尝试使用命名空间，然后取消绑定(bind)所有命名空间，但在单击文本框后仍然可以访问键盘。

<input class="virtualKeyboardField ui-keyboard-input ui-widget-content ui-corner-all" data-val="true" data-val-required="The User name field is required." id="loginUserName" name="UserName" type="text" value="" aria-haspopup="true" role="textbox">
<script type="text/javascript">
  $(function () {
    //show login
    $("#showLogin").on({
      click: function () {
        $("#loginFormDiv").toggle("slow");
      }
    });
    $("#cb_showVKey").on('click', CheckIsToShowKey);
  });
  function CheckIsToShowKey(event) {
    //var isCheck = $("#cb_showVKey").is(':checked');
    //alert("ischecked? " + isCheck);
    if ($("#cb_showVKey").is(':checked')) {
      //if checked
      BindKeyboards();
    } else {
      //not checked
      UnBindKeyboards();
    }
  }
  function bindVirtualKeyboards() {
    $("#loginForm").delegate(".virtualKeyboardField", "click.xpto", BindKeyboards);
  }
  function UnBindKeyboards() {
    $("#loginForm").undelegate(".virtualKeyboardField", "click.xpto", BindKeyboards);
  }
  function BindKeyboards() {
    // alert(event.currentTarget.id);
    //alert("xpto");
    if ($("#cb_showVKey").is(':checked')) {
      $("#loginUserName").keyboard({
        layout: 'qwerty',
        lockInput: true,
        preventPaste: true
      });
      $("#loginUserPassword").keyboard({
        layout: 'qwerty',
        lockInput: true,
        preventPaste: true
      });
    }
  }
  $(document).ready(function () {
    $("#loginForm").validate();
    BindKeyboards();
  });
</script>

有什么帮助吗？

Answer 1

这就是你所需要的

var keys;
var key_init=function() {keys=$('#keyboard').keyboard().getkeyboard();};

key_init();
$('#switch_kbd').change(
  function() {
    if ($(this).attr('checked')==='checked') { key_init(); return;}
    keys.destroy();
  }
);

sample

我更新了它的 wiki，还注意到它指向 layout demo它使用相同的解决方案。

来自他们的 docs :

keyboard is the keyboard data object which you can also access using $('#keyboard').getkeyboard()

Use keyboard.destroy()

• This function completely removes the keyboard and events from the input.
• This function is needed if you plan to change the keyboard layout when using the same input. See the layout demo.
