宜人贷项目里-----正则匹配input输入月份规则

在标签上可以直接进行校验如下,如果只调数字键盘type=number不好用可以用type=tel

<input name="creditDate" oninput="value = value.replace(/[^\d{2}\/{1}\d{2}$]/ig,'')"   @keyup="changeVal"   v-model="getDate" type="text" placeholder="月/年">

changeVal(e){
    let $val = e.currentTarget.value;
    e.currentTarget.value = $val.replace(/[^\d{2}\/{1}\d{2}$]/ig,'')
    let inputVal = e.currentTarget.value
    this.all = true;
    if(/^[2-9]/ig.test(inputVal)){
        e.currentTarget.value = '0'+inputVal
        this.all1 = true;
    }
    if(/^[1]/ig.test(inputVal)){
        e.currentTarget.value = e.currentTarget.value.replace(/^1[^0-2|/]/ig,'1')
        this.all1 = true;
    }
    if(/^[0]/ig.test(inputVal)){
        e.currentTarget.value = e.currentTarget.value.replace(/^0[^1-9|/]/ig,'0')
        this.all1 = true;
    }
    if(e.currentTarget.value.length == 2 && e.keyCode !=8 && !/^1\//ig.test(e.currentTarget.value)){
        e.currentTarget.value = e.currentTarget.value + '/'
        this.all2 = true;
    }
    if(e.currentTarget.value.length >= 5){
        e.currentTarget.value = e.currentTarget.value.substr(0,5)
        this.all3 = true;
    }
    e.currentTarget.value = e.currentTarget.value.replace(/[^\d{2}\/{1}\d{2}$]/ig,'')
    this.getDate = e.currentTarget.value
    if(this.all && this.all1 && this.all2 && this.all3){
        this.submitBtnFrag();
    }
}
