How do I check the value of field a if the value matches then field b will select the same value.


(function () {
“use strict”;
kintone.events.on(‘app.record.detail.show’, function (event) {

var textField = kintone.app.getFieldElements(‘textfield’);
var dropdown = document.getElementsByName(“getdr”).value;

for (var i in dropdown) {
if (textField .value.match(‘12’)) {




Do you want to determine if A and B are the same?

Here is a sample with that assumption, but I don’t think the if statement is the problem here, so this would not be what you are trying to do in the first place.

If you want to make sure that field A and field B matches, you can do so by

event object and compare them using an if statement.

kintone.events.on("app.record.detail.show", function(e) {

if(e.record.text.value === e.record.dropdown.value){

//The process if it matches



In the current process, it seems like you are trying to get the values using kintone.app.getFieldElements.

However, if you want to use field values in an event, it is better to use an event object.

Event objects:


Hopefully, this helps.


Hi Sean Tachibana,

I want the value of the dropdown to automatically select according to the value of the text property, if the element is the same.


Text A  : input: value 12 or 12K

DropDown B: value : 12K, 13G,14R ,15P

Result: Dropdown selected(auto when run app): 12K

Hi Sean Tachibana,

Maybe you do not understand, so sorry,

please see this picture.

text field: keyboard input ( ex: 07)

dropdown value: 01,02,03,04,05,06,07,08,09,10,11,12

Thanks you!


I just made a sample code of what you want to do.

Please use it as your reference.

(function() {
'use strict';
var events=['app.record.detail.show','app.record.create.show','app.record.create.change.Text'];
           // 'app.record.edit.change.Text', 'app.record.create.submit.success'];

kintone.events.on(events, function(event) {
    var record = event.record;
    var check = record['Text']['value'];

    if (check.indexOf("Text") !== "") {
     record['Drop_down']['value'] = check;
   return event;

Hi Yuzo Arai,
