如何使用 JavaScript 隐藏 Android 键盘？

Question

我想在 JavaScript 中隐藏 Android 虚拟键盘。有人建议这样做：

$('#input').focus(function() {
  this.blur();
});

但如果键盘已经可见，这将不起作用。 这是可以做到的吗？

Answer 1

我找到了一个更简单的解决方案，既不需要添加元素也不需要特殊类。 在那里找到它： http : //www.sencha.com/forum/archive/index.php/t-141560.html

并将代码转换为 jquery ：

function hideKeyboard(element) {
    element.attr('readonly', 'readonly'); // Force keyboard to hide on input field.
    element.attr('disabled', 'true'); // Force keyboard to hide on textarea field.
    setTimeout(function() {
        element.blur();  //actually close the keyboard
        // Remove readonly attribute after keyboard is hidden.
        element.removeAttr('readonly');
        element.removeAttr('disabled');
    }, 100);
}

您可以通过将打开键盘的输入传递给函数来调用该函数，或者仅传递 $('input') 也应该起作用。

Answer 2

您需要做的是创建一个新的输入字段，将其附加到正文，将其聚焦并使用display:none隐藏它。 不幸的是，您需要将这些包含在一些 setTimeouts 中才能完成这项工作。

var field = document.createElement('input');
field.setAttribute('type', 'text');
document.body.appendChild(field);

setTimeout(function() {
    field.focus();
    setTimeout(function() {
        field.setAttribute('style', 'display:none;');
    }, 50);
}, 50);

Answer 3

这是适用于 Android 2.3.x 和 4.x 的防弹方法

您可以使用此链接测试此代码： http : //jsbin.com/pebomuda/14

function hideKeyboard() {
  //this set timeout needed for case when hideKeyborad
  //is called inside of 'onfocus' event handler
  setTimeout(function() {

    //creating temp field
    var field = document.createElement('input');
    field.setAttribute('type', 'text');
    //hiding temp field from peoples eyes
    //-webkit-user-modify is nessesary for Android 4.x
    field.setAttribute('style', 'position:absolute; top: 0px; opacity: 0; -webkit-user-modify: read-write-plaintext-only; left:0px;');
    document.body.appendChild(field);

    //adding onfocus event handler for out temp field
    field.onfocus = function(){
      //this timeout of 200ms is nessasary for Android 2.3.x
      setTimeout(function() {

        field.setAttribute('style', 'display:none;');
        setTimeout(function() {
          document.body.removeChild(field);
          document.body.focus();
        }, 14);

      }, 200);
    };
    //focusing it
    field.focus();

  }, 50);
}

Answer 4

您现在可以在最新的浏览器上使用 inputmode="none"。 看：

https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/inputmode

Answer 5

对于使用带有cordova 的vuejs 或jquery 的任何人，请使用 document.activeElement.blur() ；

hideKeyboard() {
    document.activeElement.blur();
}

..从我的文本框中，我只是调用该函数：

对于VueJS ： v-on:keyup.enter="hideKeyboard"按回车按钮关闭 android 键盘。

对于 jQuery：

$('element').keypress(function(e) {
  if(e.keyCode===13) document.activeElement.blur();
}

Answer 6

只需模糊活动的聚焦输入字段：

$(document.activeElement).filter(':input:focus').blur();

Answer 7

我从 QuickFix 的答案中制作了一个 jquery 插件

(function ($) {
  $.fn.hideKeyboard = function() {
    var inputs = this.filter("input").attr('readonly', 'readonly'); // Force keyboard to hide on input field.
    var textareas = this.filter("textarea").attr('disabled', 'true'); // Force keyboard to hide on textarea field.
    setTimeout(function() {
      inputs.blur().removeAttr('readonly');  //actually close the keyboard and remove attributes
      textareas.blur().removeAttr('disabled');
    }, 100);
    return this;
  };
}( jQuery ));

用法示例：

$('#myInput').hideKeyboard(); 
$('#myForm input,#myForm textarea').hideKeyboard(); 

Answer 8

如果您找不到一个简单的解决方案来执行此操作，您始终可以只从 javascript 调用 java 代码。 教程和示例在这里。 在这里隐藏软键盘。

...
WebView webView = (WebView) findViewById(R.id.webview);
webView.addJavascriptInterface(new JavaScriptInterface(this), "Android");
....

public class JavaScriptInterface {
    Context mContext;

    /** Instantiate the interface and set the context */
    JavaScriptInterface(Context c) {
        mContext = c;
    }

    /** Show a toast from the web page */
    public void hideKeyboard() {
        InputMethodManager imm = (InputMethodManager)mContext.getSystemService(Context.INPUT_METHOD_SERVICE);
        ...
    }
}

javascript

<script type="text/javascript">
function hideAndroidKeyboard() {
    Android.hideKeyboard();
}
</script>

需要注意的事项：

Javascript to Native Java 不适用于模拟器版本 2.3+。 http://code.google.com/p/android/issues/detail?id=12987 。

我不确定，但是当调用 hideKeyboard 时，您可能不在主线程上。

这当然是如果您找不到简单的解决方案。

Answer 9

我已经解决了这个问题，用这个“$(input).prop('readonly',true);” 在之前显示

前任：

$('input.datepicker').datepicker(
                        {   
                            changeMonth: false,
                            changeYear: false,
                            beforeShow: function(input, instance) { 
                                $(input).datepicker('setDate', new Date());
                                $(input).prop('readonly',true);
                            }
                        }                         
                     ); 

Answer 10

View view = this.getCurrentFocus();
if (view != null) {  
    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

Answer 11

VueJS一个班轮：

<input type="text" ref="searchBox" @keyup.enter="$refs.searchBox.blur()" />

或者你可以用this.$refs.searchBox.blur();将它隐藏在 JS 中this.$refs.searchBox.blur();

Answer 12

rdougan 的帖子对我不起作用，但它是我解决方案的一个很好的起点。

function androidSoftKeyHideFix(selectorName){
    $(selectorName).on('focus', function (event) {
        $(selectorName).off('focus')
        $('body').on('touchend', function (event) {
            $('body').off('touchend')
            $('.blurBox').focus();
            setTimeout(function() {
                $('.blurBox').blur();
                $('.blurBox').focus();
                $('.blurBox').blur();
                androidSoftKeyHideFix(selectorName); 
            },1)
        });
    });
}    

您需要在正文顶部有一个输入元素，我将其归类为“blurBox”。 它不能是 display:none。 所以给它不透明度：0 和位置：绝对。 我试着把它放在身体的底部，但没有用。

我发现有必要在 blurBox 上重复 .focus() .blur() 序列。 我没有试过，它不起作用。

这适用于我的 2.3 Android。 我想自定义键盘应用程序可能仍然存在问题。

在到达此之前，我遇到了许多问题。 随后的焦点重新触发模糊/焦点有一个奇怪的问题，这似乎是一个 android 错误。 我使用 touchend 侦听器而不是模糊侦听器来绕过在非初始打开后立即关闭键盘的功能。 我也遇到了键盘打字使滚动条四处跳跃的问题……这与父级上使用的 3d 变换有关。 这是为了解决模糊重燃问题的尝试而产生的，我最后没有取消模糊盒的模糊。 所以这是一个微妙的解决方案。

Answer 13

给软键盘一些时间来关闭我的作品。

$('#ButtonCancel').click(function () {
    document.body.focus();

    setTimeout(function () {
        //close the dialog, switch to another screen, etc.
    }, 300);
});

Answer 14

只需禁用表单字段：

document.getElementById('input').disabled

Answer 15

防止键盘显示输入的简单 jQuery插件：

(function ($) {
    $.fn.preventKeyboard = function () {
        return this
            .filter('input')
            .on('focus', function () {
                $(this)
                    .attr('readonly', 'readonly')
                    .blur()
                    .removeAttr('readonly');
            });
    };
}(jQuery));

用法

这对于附加了一些日期选择器的日期字段很有用。

$('#my_datepicker_field').preventKeyboard();

在您的智能手机上试试下面的代码片段！

（或在https://jsfiddle.net/dtyzLjhw/上查看）

 (function($) { // Create plugin that prevents showing the keyboard $.fn.preventKeyboard = function() { return this .filter('input') .on('focus', function() { $(this) .attr('readonly', 'readonly') .blur() .removeAttr('readonly'); }); }; $(document).ready(function($) { // Date field has datepicker attached. $('input[name=date]').datepicker(); // Prevent showing keyboard for the date field. $('input[name=date]').preventKeyboard(); }); }(jQuery));

Answer 16

在尝试了此页面上的所有答案后，这对我有用：

function HideVirtualKeyboard(element_id) {
   // Set the input field to read-only and then back to normal.
   $("#" + element_id).attr("readonly", "readonly");
   setTimeout(function() { $("#" + element_id).removeAttr("readonly"); }, 1);
}

调用它：

HideVirtualKeyboard("input");

当我尝试模糊输入字段时，它隐藏了键盘，但由于我总是需要将焦点放在输入字段中，所以一旦我再次聚焦，键盘就会立即恢复。 通过将其设置为只读然后恢复正常，它隐藏了键盘但永远不会失去焦点。

Answer 17

我来晚了一点，但我想分享一个适用于我的解决方案，适用于 Android 2.5.x+ 和 iOS 7。

我的大问题是在方向改变时关闭键盘。 这会在任何浏览器方向更改后产生可恢复的（意味着大部分是优雅的）状态。

这是咖啡脚本：

@windowRepair: (mobileOS) ->
  activeElement = document.activeElement.tagName
  if activeElement == "TEXTAREA" or activeElement == "INPUT"
    $(document.activeElement).blur()
    #alert "Active Element " + activeElement + " detected"
  else
    $('body').focus()
    #alert "Fallback Focus Initiated"
  if mobileOS == "iOS"
    window.scrollTo(0,0)
  $('body').css("width", window.innerWidth)
  $('body').css("height", window.innerHeight)

我希望这对某人有帮助。 我知道我花了很多时间弄明白。

Answer 18

HTML

<input type="text" id="txtFocus" style="display:none;">

脚本

$('#txtFocus').show().focus().hide();
$.msg({ content : 'Alert using jquery msg' });

Answer 19

我设法让它与以下一起工作

document.body.addEventListener( 'touchend', function(){
    if( document.getElementById('yourInputFiled') )
        document.getElementById('yourInputFiled').blur();    
});

和 preventDefault() 和 stopPropagation() 在您的输入字段的侦听器中

Answer 20

您无法使用 js 正确隐藏键盘，因为它是操作系统问题，因此您可以轻松“隐藏”键盘的一件事是，您可以使用输入元素来制作任何“非输入 html 元素”只需添加 [tabindex] 属性，即可轻松监听 keydown 和 keyup 事件并将“$event.target.value”存储在变量中以获取输入。

Answer 21

检查这个，它的保证和容易！

• 每当您不希望键盘显示时，将“只读”属性添加到输入字段

 $("#inputField").attr("readonly","readonly");

• 单击它时重置

     $("#inputField").click(function () {
              $(this).removeAttr("readonly");
              $(this).focus();  
      });

Answer 22

这是我所做的（来自https://github.com/danielnixon/oaf-side-effects ）：

/**
 * Hide the on-screen keyboard on touch devices like iOS and Android.
 *
 * It's useful to do this after a form submission that doesn't navigate away from the
 * current page but does update some part of the current page (e.g. dynamically updated
 * search results). If you weren't to do this the user might not be shown any feedback
 * in response to their action (form submission), because it is obscured by the keyboard.
 *
 * To hide the keyboard we temporarily set the active input or textarea to readonly and
 * disabled. To avoid a flash of readonly/disabled styles (often a gray background) you
 * can hook into the [data-oaf-keyboard-hack] html attribute. For example:
 *
 * ```
 *  // Readonly/disabled styles shouldn't be applied when this attribute is present.
 *  [data-oaf-keyboard-hack] {
 *    background-color: $input-bg !important;
 *  }
 * ```
 *
 * Note that lots of people simply `blur()` the focused input to achieve this result
 * but doing that is hostile to keyboard users and users of other AT.
 *
 * Do you need to use this?
 *
 * 1. If your form submission triggers a full page reload, you don't need this.
 * 2. If your form submission explicitly moves focus to some other element, you
 * don't need this. For example you might move focus to some new content that
 * was loaded as a result of the form submission or to a loading message.
 * 3. If your form submission leaves focus where it is, you probably want this.

角度版本：

export component FooComponent {
  @ViewChild('bsDatePicker') calendarInput: ElementRef;

  focus(): void {
    const nativeElement = this.calendarInput.nativeElement;

    setTimeout(() => {
      nativeElement.blur();
    }, 100);
  }
}

和模板：

<input
   #bsDatePicker
   bsDatepicker
   type="text"
   (focus)="focus()"/>

Answer 24

不幸的是，这可能不是最直接的解决方案，但似乎正在开发一种名为Virtual Keyboard API的新工具，旨在为开发人员在移动设备上的本机键盘提供更大的灵活性。

这个新功能的W3C 工作草案看起来就像是在去年 9 月才发布的，所以请注意，目前浏览器对这个功能的支持将是最低限度的。

使用这个新的 API，可以使用以下代码显示和隐藏虚拟键盘：

navigator.virtualKeyboard.show();
navigator.virtualKeyboard.hide();

使用这些方法时必须满足一些特殊条件。 最值得注意的是，元素的virtualKeyboardPolicy （ 它是虚拟键盘 API 中也引入的一个新属性）必须设置为manual 。

这意味着当给定元素获得焦点时，键盘不会自动打开。 您必须完全自己处理虚拟键盘的显示/隐藏。

要检查当前浏览器是否支持虚拟键盘 API， 请使用以下代码：

if ('virtualKeyboard' in navigator)

事实上，对我来说，上述表达式在 Chrome 上的计算结果为true ，但在 FireFox 中（还没有）。

然而，这是意料之中的，因为根据 Chrome 平台状态，该功能是在 2021 年 9 月 21 日刚刚发布的 Chrome v94 中提供的，因此其他浏览器需要一段时间才能实现它（也就是说，如果他们曾经这样做过）：

Answer 25

您可以使用@keyup功能在Vue.js中轻松实现此功能...

<input @keyup.enter="closeMobileKeyboard($event)"/>

function closeMobileKeyboard(event) {
  event.target.blur();
}

Answer 26

我想在JavaScript中隐藏Android虚拟键盘。 有人建议做此：

$('#input').focus(function() {
  this.blur();
});

但是，如果键盘已经可见，这将不起作用。 这是可以做到的吗？
