PouchDB：單選按鈕值未保存到數據庫

Question

我有一個帶有單選按鈕的表單，該表單將數據保存到PouchDB實例。 文本字段將保存到PouchDB。

單選按鈕的值不會保存到PouchDB中 。 重新加載數據時，在輸入上單擊的值不會顯示。

（還添加了viewnote函數，以防它們無法正確顯示。）

的JavaScript

    PouchNotesObj.prototype.savenote = function () {
        'use strict';
        var o = {}, that = this;

        if (!this.formobject._id.value) {
            o._id = new Date().getTime() + '';
        } else {
            o._id = this.formobject._id.value;
        }

        if (this.formobject._rev.value) {
            o._rev = this.formobject._rev.value;
        }

        o.preferred      = (this.formobject.preferred.value == '') ? '' : this.formobject.preferred.value;
        o.application_access      = (this.formobject.application_access.value == '') ? '' : this.formobject.application_access.value;
        o.modified  = new Date().getTime();

        this.pdb.put(o, function (error, response) {
            if(error){
                that.showerror(error);
            }

            if(response && response.ok){

                that.viewnoteset();
                that.formobject.reset();

                that.show(that.formobject.dataset.show);
                that.hide(that.formobject.dataset.hide);

                viewnotes.dispatchEvent(new MouseEvent('click'));
            }
        });

        this.resethash();
    };

PouchNotesObj.prototype.viewnote = function (noteid) {
    'use strict';

    var that = this, noteform = this.formobject;

    this.pdb.get(noteid, {attachments:true}, function (error, response) {
        var fields = Object.keys(response), o, link, attachments, li;

        if (error) {
            this.showerror();
            return;
        } else {

            fields.map( function (f) {
                if (noteform[f] !== undefined && noteform[f].type != 'file') {
                    noteform[f].value = response[f];
                }


            // fill in form fields with response data.
            that.show('#addnote');
            that.hide('section:not(#addnote)');
            that.show('#attachments');
        }
    });

Answer 1

單選按鈕選擇的值沒有保存到數據庫中，因為JavaScript沒有得到它。

它需要指出已檢查input的值。

var selectedPref = document.querySelector('input[name="preferred"]:checked').value;
o.preferred      = (selectedPref == '') ? '' : selectedPref;
var selectedAppAccess = document.querySelector('input[name="application_access"]:checked').value;
o.application_access      = (selectedAppAccess == '') ? '' : selectedAppAccess;
