禁止输入框输入特殊符号或emoji表情
// 判断是否含有特殊符号
let reg1 = /[`~!@#$%^&*()_\-+=<>?:"{}|,.\/;'\\[\]·~!@#¥%……&*()——\-+={}|《》?:“”【】、;‘’,。、]/im
// 判断是否含有emoji表情
let reg2 = /[\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
// 如果为true,字符串含有emoji表情,false不含
console.log(reg2.test(info.personName))
// 如果为true,字符串含有特殊符号,false不含
console.log(reg1.test(info.personName))
使用:
onInput() {
var reg = /[\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
this.input = this.input.replace(reg, '')
},
全局设置:
let findEle = (parent, type) => {
return parent.tagName.toLowerCase() === type ? parent : parent.querySelector(type)
}
const trigger = (el, type) => {
const e = document.createEvent('HTMLEvents')
e.initEvent(type, true, true)
el.dispatchEvent(e)
}
const emoji = {
bind: function (el, binding, vnode) {
// 正则规则可根据需求自定义
var regRule = /[\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
let $inp = findEle(el, 'input')
el.$inp = $inp
$inp.handle = function () {
let val = $inp.value
$inp.value = val.replace(regRule, '')
trigger($inp, 'input')
}
$inp.addEventListener('keyup', $inp.handle)
},
unbind: function (el) {
el.$inp.removeEventListener('keyup', el.$inp.handle)
},
}
export default emoji
使用:将需要校验的输入框加上 v-emoji
即可
