如何使用JavaScript删除表情符号代码?我以为我使用下面的代码照顾它,但我仍然有像。

这样的字符
function removeInvalidChars() {
    return this.replace(/[\uE000-\uF8FF]/g, '');
}

您选择的范围是包含非标准字符的专用区。用于将表情符号编码为此范围内不同的不一致值的载体。

最近,表情符号已被赋予标准化的“统一”代码点。其中许多都在基本多语言平面之外,在块U + 1F300-U + 1F5FF中,包括你的例子U + 1F534大红圈。

您可以在支持非BMP字符的正则表达式引擎中使用[\U0001F300-\U0001F5FF]检测这些字符,但JavaScript的RegExp不是这样的野兽。不幸的是,JS字符串模型基于UTF-16代码单元,所以你必须在正则表达式中使用UTF-16代理:

return this.replace(/([\uE000-\uF8FF]|\uD83C[\uDF00-\uDFFF]|\uD83D[\uDC00-\uDDFF])/g, '')

但请注意,基本多语言平面中还有其他字符被电话用作表情符号,但很久以前就是表情符号。例如,U + 2665是传统的Heart Suit角色♥,但它在某些设备上被渲染为表情符号图形。您是否将其视为表情符号并尝试将其删除,由您决定。有关更多示例,请参阅this list

对我来说,没有一个答案完全删除了所有表情符号所以我必须自己做一些工作,这就是我得到的:

text.replace(/([\uE000-\uF8FF]|\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDFFF]|[\u2011-\u26FF]|\uD83E[\uDD10-\uDDFF])/g, '');

此外,它应该考虑到如果稍后将字符串插入数据库,替换为空字符串可能会暴露安全问题。而是替换为替换字符U + FFFD,请参阅:http://www.unicode.org/reports/tr36/#Deletion_of_Noncharacters

我发现了许多建议,但解决了我的问题的正则表达式是:

/(?:[\u2700-\u27bf]|(?:\ud83c[\udde6-\uddff]){2}|[\ud800-\udbff][\udc00-\udfff]|[\u0023-\u0039]\ufe0f?\u20e3|\u3299|\u3297|\u303d|\u3030|\u24c2|\ud83c[\udd70-\udd71]|\ud83c[\udd7e-\udd7f]|\ud83c\udd8e|\ud83c[\udd91-\udd9a]|\ud83c[\udde6-\uddff]|\ud83c[\ude01-\ude02]|\ud83c\ude1a|\ud83c\ude2f|\ud83c[\ude32-\ude3a]|\ud83c[\ude50-\ude51]|\u203c|\u2049|[\u25aa-\u25ab]|\u25b6|\u25c0|[\u25fb-\u25fe]|\u00a9|\u00ae|\u2122|\u2139|\ud83c\udc04|[\u2600-\u26FF]|\u2b05|\u2b06|\u2b07|\u2b1b|\u2b1c|\u2b50|\u2b55|\u231a|\u231b|\u2328|\u23cf|[\u23e9-\u23f3]|[\u23f8-\u23fa]|\ud83c\udccf|\u2934|\u2935|[\u2190-\u21ff])/g

一个简短的例子

function removeEmojis (string) {
  var regex = /(?:[\u2700-\u27bf]|(?:\ud83c[\udde6-\uddff]){2}|[\ud800-\udbff][\udc00-\udfff]|[\u0023-\u0039]\ufe0f?\u20e3|\u3299|\u3297|\u303d|\u3030|\u24c2|\ud83c[\udd70-\udd71]|\ud83c[\udd7e-\udd7f]|\ud83c\udd8e|\ud83c[\udd91-\udd9a]|\ud83c[\udde6-\uddff]|\ud83c[\ude01-\ude02]|\ud83c\ude1a|\ud83c\ude2f|\ud83c[\ude32-\ude3a]|\ud83c[\ude50-\ude51]|\u203c|\u2049|[\u25aa-\u25ab]|\u25b6|\u25c0|[\u25fb-\u25fe]|\u00a9|\u00ae|\u2122|\u2139|\ud83c\udc04|[\u2600-\u26FF]|\u2b05|\u2b06|\u2b07|\u2b1b|\u2b1c|\u2b50|\u2b55|\u231a|\u231b|\u2328|\u23cf|[\u23e9-\u23f3]|[\u23f8-\u23fa]|\ud83c\udccf|\u2934|\u2935|[\u2190-\u21ff])/g;
  return string.replace(regex, '');
}

@ bobince的解决方案对我不起作用。要么Emojis留在那里,要么他们被不同的表情符号交换。

这个解决方案为我做了诀窍:

var ranges = [
  '\ud83c[\udf00-\udfff]', // U+1F300 to U+1F3FF
  '\ud83d[\udc00-\ude4f]', // U+1F400 to U+1F64F
  '\ud83d[\ude80-\udeff]' // U+1F680 to U+1F6FF
];


$('#mybtn').on('click', function() {
  removeInvalidChars();
})

function removeInvalidChars() {
  var str = $('#myinput').val();

  str = str.replace(new RegExp(ranges.join('|'), 'g'), '');
  $("#myinput").val(str);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="myinput"/>
<input type="submit" id="mybtn" value="clear"/>

我通过使用带有Unicode property escapes的正则表达式解决了这个问题。我是从本文中获得的,它是针对Java的,但仍然非常有用-Remove Emojis from a Java String

'Smile?'.replace(/[^\p{L}\p{N}\p{P}\p{Z}]/gu, '');

它将删除所有符号,除了:

  • \ p {L}-任何语言的所有字母
  • \ p {N}-数字
  • \ p {P}-标点符号
  • \ p {Z}-空格分隔符

这应该更正确并且有效,但是对我来说,它在字符串中留下了一些垃圾符号:

    'Smile?'.replace(/\p{Emoji}/gu, '');

我知道这篇文章有点陈旧,但我在工作中偶然发现了这个问题,一位同事提出了一个有趣的想法。基本上不是剥离表情符号字符只允许有效字符。咨询此ASCII表:

http://www.asciitable.com/

此类功能只能保留合法字符(范围本身取决于您所追求的内容)

function (input) {
            var result = '';
            if (input.length == 0)
                return input;
            for (var indexOfInput = 0, lengthOfInput = input.length; indexOfInput < lengthOfInput; indexOfInput++) {
                var charAtSpecificIndex = input[indexOfInput].charCodeAt(0);
                if ((32 <= charAtSpecificIndex) && (charAtSpecificIndex <= 126)) {
                    result += input[indexOfInput];
                }
            }
            return result;
        };

如果您希望保留英文字母+数字+特殊字符,则应保留字母的所有数字,字母和特殊字符。希望它可以帮助某人:)

这里没有任何答案适用于我测试过的所有unicode字符(特别是mis或☯️等杂项中的字符)。

这是一个适合我的工作,(大量)灵感来自this SO PHP answer

function _removeEmojis(str) {
  return str.replace(/([#0-9]\u20E3)|[\xA9\xAE\u203C\u2047-\u2049\u2122\u2139\u3030\u303D\u3297\u3299][\uFE00-\uFEFF]?|[\u2190-\u21FF][\uFE00-\uFEFF]?|[\u2300-\u23FF][\uFE00-\uFEFF]?|[\u2460-\u24FF][\uFE00-\uFEFF]?|[\u25A0-\u25FF][\uFE00-\uFEFF]?|[\u2600-\u27BF][\uFE00-\uFEFF]?|[\u2900-\u297F][\uFE00-\uFEFF]?|[\u2B00-\u2BF0][\uFE00-\uFEFF]?|(?:\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDEFF])[\uFE00-\uFEFF]?/g, '');
}

(我的用例是在数据网格中排序,其中表情符号可以首先出现在字符串中,但用户希望按实际单词排序文本。)

答案 7 :(得分:1)

sandre89's answer很好但不完美。 我花了一些时间在这个问题上,并有一个有效的解决方案。

var ranges = [
  '[\u00A0-\u269f]',
  '[\u26A0-\u329f]',
  // The following characters could not be minified correctly
  // if specifed with the ES6 syntax \u{1F400}
  '[-]'
  //'[\u{1F004}-\u{1F9C0}]'
];


$('#mybtn').on('click', function() {
  removeInvalidChars();
});

function removeInvalidChars() {
  var str = $('#myinput').val();
  str = str.replace(new RegExp(ranges.join('|'), 'ug'), '');
  $("#myinput").val(str);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="myinput" />
<input type="submit" id="mybtn" value="clear" />

这是my CodePen

但有几点需要注意。

  1. 来自U+1F000的Unicode字符需要一个特殊符号,因此您可以使用sandre89的方式,或选择\u{1F000} ES6表示法,这可能与您的缩小器有效,也可能不兼容。我成功地直接用UTF-8编码的脚本粘贴表情符号。

  2. 不要忘记正则表达式中的u标记,否则您的Javascript引擎可能会抛出错误。

  3. 请注意,由于文件编码,字符集或缩小器,事情可能无法正常工作。在我的情况下,没有任何工作,直到我从.isml文件(Demandware)上取下脚本并将其粘贴到.js文件中。

    您可以通过引用Wikipedia Emoji pageHow many bytes does one Unicode character take?以及修改此Online Unicode converter来获得一些见解,就像我一样。

str.replace(emoji, "");

我添加此'\ uD83E [\ udd00- \ uddff]'

这些表情符号是在2018年6月更新的

如果您要在其他更新后阻止表情符号,请使用此

str.replace(/[^0-9a-zA-Zㄱ-힣+×÷=%♤♡☆♧)(*&^/~#@!-:;,?`_|<>{}¥£€$◇■□●○•°※¤《》¡¿₩\[\]\"\' \\]/g ,"");

u可以阻止所有表情符号,并且只能使用eng,num,hangle和某些字符 thx:)

这是对@hababr 的回答的迭代。
他的回答删除了许多标准字符,如 $+< 等。
这个版本保留了所有这些(除了 \ 反斜杠 - 不知道如何正确转义它)

"hey? hau? ahoy?‍☠️ !@#$%^&*()-_=+±§;:'\|`~/?[]{},.<>".replace(/[^\p{L}\p{N}\p{P}\p{Z}{^$=+±\\'|`\\~<>}]/gu, "")
// "hey hau ahoy !@#$%^&*()-_=+±§;:'|`~/?[]{},.<>"

在搜索并尝试了很多 unicode regex 之后,我建议你试试这个,它可以覆盖所有的表情符号

function removeEmoji(str) {
  let strCopy = str;
  const emojiKeycapRegex = /[\u0023-\u0039]\ufe0f?\u20e3/g;
  const emojiRegex = /\p{Extended_Pictographic}/gu;
  const emojiComponentRegex = /\p{Emoji_Component}/gu;
  if (emojiKeycapRegex.test(strCopy)) {
    strCopy = strCopy.replace(emojiKeycapRegex, '');
  }
  if (emojiRegex.test(strCopy)) {
    strCopy = strCopy.replace(emojiRegex, '');
  }
  if (emojiComponentRegex.test(strCopy)) {
    // eslint-disable-next-line no-restricted-syntax
    for (const emoji of (strCopy.match(emojiComponentRegex) || [])) {
      if (/[\d|*|#]/.test(emoji)) {
        continue;
      }
      strCopy = strCopy.replace(emoji, '');
    }
  }

  return strCopy;
