I Have a Apex class:

global with sharing class AccountRemoter {

    public String accountName { get; set; }

    public static Account account { get; set; }

    public AccountRemoter() { } // empty constructor


    global static list<Account> getAccount(String accountName) {

        list<account> account1 = [SELECT Id, Name, Phone, Type, NumberOfEmployees

                   FROM Account WHERE Name = :accountName];

        return account1;



Visual Force Page:

<apex:page controller="AccountRemoter">

    <script type="text/javascript">

    function getRemoteAccount() {

        var accountName = document.getElementById('acctSearch').value;




            function(result, event){

                if (event.status) {

                    // Get DOM IDs for HTML and Visualforce elements like this

                    document.getElementById('remoteAcctId').innerHTML = result.Id



                        ).innerHTML = result.NumberOfEmployees;

                } else if (event.type === 'exception') {

                    document.getElementById("responseErrors").innerHTML =

                        event.message + "<br/>\n<pre>" + event.where + "</pre>";

                } else {

                    document.getElementById("responseErrors").innerHTML = event.message;



            {escape: true}



    <input id="acctSearch" type="text"/>

    <button onclick="getRemoteAccount()">Get Account</button>

    <div id="responseErrors"></div>

    <apex:pageBlock id="block">

        <apex:pageBlockSection id="blockSection" columns="2">

            <apex:pageBlockSectionItem id="firstItem">

                <span id="remoteAcctId"/>


            <apex:pageBlockSectionItem id="secondItem">

Your Apex code return a list of Account objects not a single Account object so you need to handle the result value accordingly:

if (event.status) {
    for (var i = 0; i < result.length; i++) {
        var account = result[i];
        var id = account.Id;
        var n = result.NumberOfEmployees;
        // You will need to create e.g. a table here
        console.log('id=' + id + ' n=' + n);

You get undefined when you try to access a field of a JavaScript object that does not exist.

Note that the debug tools in browser's are excellent and a small investment in time learning about them will quickly pay back.

Have you considered not using JavaScript here? You can write a Visualforce page that has no JavaScript that does the same thing with much less code.
