I'm trying to retrieve a parameter from a success method that is called within and executeQueryAsync using Javascript ECMA scripting.
I get tried follwing the suggestion here
but I get the following error in the MicrosfotAjax.js file:
"The Collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested." in the alert(_returnParam); command, I get an undefined value when instead it should say "hello". I want to demonstrate a simple variable return before I get the success function to return listItemInfo array.
Thank you for your consideration
function Tblsrch(camlstr){
var siteUrl = '/sites/SIandT%20Project%20Intelligence';
var hello;
var clientContext = new SP.ClientContext(siteUrl);
var oWebsite = clientContext.get_web();
var oList = oWebsite.get_lists().getByTitle('ISATestdata');
var camlQuery = new SP.CamlQuery();
camlQuery.set_viewXml(camlstr);
this.collListItem = oList.getItems(camlQuery);
var _returnParam;
clientContext.executeQueryAsync(Function.createDelegate(this, function(){_returnParam = onQuerySucceeded();}), Function.createDelegate(this, this.onQueryFailed));
alert(_returnParam);
}
function onQuerySucceeded(sender, args){
var listItemInfo = new Array();
var rowInd = 0;
var hello;
var listItemEnumerator = collListItem.getEnumerator();
while (listItemEnumerator.moveNext()) {
var oListItem = listItemEnumerator.get_current();
// listItemInfo += '\nType:' + oListItem.get_item('Name2') + ' | ' + oListItem.get_item('Plan') + ' | ' + oListItem.get_item('Type1');
