vue 密码显示星号

组件代码

 watch: {
        safepwd: {
            handler(newv) {
                let a = newv.replace(/[*]/g, "");
                let b = newv.replace(/[^*]/g, "");
                this.safepassword = this.safepassword.substring(0, b.length);
                this.safepassword += a;
                this.safepwd = this.safepassword.replace(/./g, "*");
                console.log(this.safepassword)
            },
            immediate: true,
        }
    },

这个暂时不支持文本中间修改插入密码，只能从后面新增删除，不过还是很简单的，够用了
