Moving a List Item attachment from one list to another

Hi,
What are the best way of coping / moving the List Item attachment using
jQuery / JavaScript in SharePoint 2013 from one list to another.
Thanks

Impossible is nth but good coding :-)

Answer 1

For your needs better try to code your own solution. See
SharePoint JavaScript Class Library for details. You can have two possible architectures:
Make all work from JavaScript. And the first your step will be
addItem method of SP.List.
Make processing of selection on client in JavaScript and call your custom server-side component (may be an application page) for items copying (creating copies in new list of already existed items from initial list.). See
this for example.
Also be careful with context.load. It's recommended to write all next code in context.executeQueryAsync. Use Firebug in FF and developer tools in Chrome for debugging your code and to find what is wrong.

<script type="text/javascript">
ExecuteOrDelayUntilScriptLoaded(retrieveListItems, "sp.js");
var siteUrl = 'Site Url';
function retrieveListItems() {
var clientContext = new SP.ClientContext(siteUrl);
var oList = clientContext.get_web().get_lists().getByTitle('List1');
var camlQuery = new SP.CamlQuery();
camlQuery.set_viewXml('<View><Query><Where><Geq><FieldRef Name=\'ID\'/>' +
'<Value Type=\'Number\'>1</Value></Geq></Where></Query><RowLimit>10</RowLimit></View>');
this.collListItem = oList.getItems(camlQuery);
clientContext.load(collListItem);
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
function onQuerySucceeded(sender, args) {
var listItemInfo = '';
var listItemEnumerator = collListItem.getEnumerator();
while (listItemEnumerator.moveNext()) {
var objListItem = listItemEnumerator.get_current();
var clientContext = new SP.ClientContext(siteUrl);
var oList = clientContext.get_web().get_lists().getByTitle('List2');
var itemCreateInfo = new SP.ListItemCreationInformation();
this.oListItem = oList.addItem(itemCreateInfo);
oListItem.set_item('Title', objListItem.get_item('Title'));
oListItem.update();
clientContext.load(oListItem);
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceededFinal), Function.createDelegate(this, this.onQueryFailed));
function onQueryFailed(sender, args) {
alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
function onQuerySucceededFinal(sender, args) {
//Do next set of operation if needed
</script><input name="btnVarIQReject" onclick="retrieveListItems()" type="button" value="Submit"/>
Please use my above POC code to start. This will copy all the title field value from list1 to list2
