输入内容过滤空格和emoji表情

1.定义一个公共的js文件 commonMethod.js

/** 替换emoji表情 */

function filterEmoji(name){

var str = name.replace(/[\uD83C|\uD83D|\uD83E][\uDC00-\uDFFF][\u200D|\uFE0F]|[\uD83C|\uD83D|\uD83E][\uDC00-\uDFFF]|[0-9|*|#]\uFE0F\u20E3|[0-9|#]\u20E3|[\u203C-\u3299]\uFE0F\u200D|[\u203C-\u3299]\uFE0F|[\u2122-\u2B55]|\u303D|[\A9|\AE]\u3030|\uA9|\uAE|\u3030/ig, “”);

return str;

}

/** 替换空格键2 */

function filterSpace(name){

var str = name..replace(/\s+/g, ”);

return str;

}

module.exports = {

filterEmoji: filterEmoji,

filterSpace:filterSpace

}

2.在所需要的文件中使用

wxml文件

js文件

var commonMethod = require(“../../utils/commonMethod.js”);  //根据自己的项目做出修改

nameInput: function (e) {

var that = this;

var str = commonMethod.filterEmoji(e.detail.value);

that.setData({

repairsDescribe: commonMethod.filterSpace(str);

})

},
简洁过滤

var userNick = e.detail.userInfo.nickName.replace(/\%uD.{3}/g, ”);

只要看正则过滤
