I have developed page with autoComplete feature. I'm getting an Uncaught SyntaxError: Unexpected identifier error because of symbols used in Account Names such as "诸城金盛-abc Commerce and" Co., Ltd. I'm posting my code for reference.

Visualforce page Code:

<apex:page id="pageId" standardController="Account"  lightningStylesheets="{!$User.UIThemeDisplayed == 'Theme4d'}" extensions="SFI_AccountExtension">
    <html lang="en">
        <meta charset="utf-8"/>
        <meta name="viewport" content="width=device-width, initial-scale=1"/>
        <title>jQuery UI Autocomplete - Default functionality</title>
        <link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css"/>
            .ui-autocomplete {
            max-height: 100px;
            overflow-y: auto;

            overflow-x: hidden;

            * html .ui-autocomplete {
            height: 100px;

            td.data2Col {
            text-align: center !important;

table {

td,th { 


width : 50px !important;

width : 50px !important;
    padding-bottom: 20px;

                                <apex:outputPanel >
                                    <th><apex:outputLabel value="Account" style="color: #4a4a56; font-weight: bold; font-size:91%;  text-align: left; "></apex:outputLabel></th>
                                        <div class="requiredInput"><div class="requiredBlock"></div>
                                            <apex:inputText label="Account " value="{!selectedAccount}"  id="AccountIds"    style="width : 206px;" />


        $( function() {
            var availableTags = {!accList};

                source: availableTags
        } );


Apex Code:

public class SFI_AccountExtension {
    public Account accountRecord {

    public List < String > accList {
     public String  selectedAccount{
    public SFI_AccountExtension(ApexPages.StandardController sc) {
            selectedAccount = '';
            accountRecord = (Account) sc.getRecord();

        getAccountList();//method to load list of accounts


    //Method to supply list of account with the record type name 'SAP Sold-To Customer' present in salesforce for auto complete
    public List < String > getAccountList() {
        accList = new List < String > ();
        Id RecordTypeId = [SELECT Id, Name FROM RecordType WHERE SobjectType = 'Account'
                           AND Name = 'SAP Sold-To Customer'
                           limit 1
        for (Account acc: [select name, SAP_Customer_Number__c from Account where recordTypeId =: RecordTypeId]) {
            accList.add('"' + acc.SAP_Customer_Number__c + ' - ' + acc.name + '"');
        return accList;


Can somebody please tell how to avoid this type of error.

It sounds like you'll need to encode your data:

var availableTags = JSON.parse("{!JSENCODE(accList)}");

This may still result in errors, but it should be closer to what you're looking for.

  • Hi @sfdcfox when I'm trying to use this I'm getting this error " Error: Incorrect argument type for function 'JSENCODE()'. "

  • In that case, you might need to to JSON.serialize on the server side, then use the JSON string. You can't ordinarily have JavaScript variables with odd names, it's a limitation of JavaScript.
