Sorry for a simple question. I'm totally new to Salesforce.

I want to pass JavaScript array to Apex to save its data in the Salesforce custom object. I want to know the best approach to do it without JavaScript remoting. Following is the JavaScript code.

$("#saveCalendar").click(function () {
        getDatesBackup = document.getElementById('selectedDates').options;
        for(var k=0; k<getDatesBackup.length; k++){
            console.log("Dates Backup : "+getDatesBackup[k].text);

  • @ShaileshPatil In that question the value is coming from the VF. In my case this is only between JS and Apex. What should be the Apex to retrieve that array from JS? – Superman Jan 13 '15 at 8:52
  • You have to define an Apex variable and set the Javascript value to it. How to do that is written in the topic mentioned by @ShaileshPatil – Sergej Utko Jan 13 '15 at 8:59

You can use ActionFunction for this. Here is sample for your reference.


public class ActionFunctionCLS {

    public void IWantToDebug() {
        list<String> ls = ( List<String> )JSON.deserialize( Apexpages.currentPage().getParameters().get('node'), List<string>.class ) ;        
        System.debug('======================= ' + ls[0] );
        System.debug('======================= ' + ls[1]);
        System.debug('======================= ' + ls[2]);                

VF Page:

    <apex:page controller="ActionFunctionCLS"  >

<script type="text/javascript">
    function doSave(node){
        var arr = ["foo", "bar", "baz"];

<apex:form >
    <apex:actionFunction name="paraFunction" action="{!IWantToDebug}" rerender="view">      
         <apex:param id="anode" name="node" value="" />

 <input type="button" onclick="doSave();" value="test" />

Note that we are calling IWantToDebug Action from JS using paraFunction Action Function.

    while useful, it doesn't address OP's requirement of passing a JS array to VF controller – cropredy Nov 26 '15 at 0:07

    updated the answer with better example. hope that brings more clarity. – AtulRajguru9 Nov 26 '15 at 7:03

    Excellent! The JSON.stringify is the key point here as Javascript objects and Apex objects need some common interchange format – cropredy Nov 26 '15 at 16:16
  • This was very helpful. I had to pass a two dimensional string from Javascript and I just had to change List<String>.class to List<List<String>>.class and it worked fine. Thanks! – javanoob Aug 21 '16 at 4:29
