Uncaught TypeError: document.getElementsByID is not a function

methods: {
        getid() {
        this.frm.id= document.getElementsByID("id");
        console.log(this.frm.id);
      },
      getpwd() {
        this.frm.pwd= document.getElementsByID("pwd");
        console.log(this.frm.pwd);
      },
     

修改后的代码

methods: {
        getid() {
        this.frm.id= document.getElementById("id");
        console.log(this.frm.id);
      },
      getpwd() {
        this.frm.pwd= document.getElementById("pwd");
        console.log(this.frm.pwd);
      },
