1. var clientContext = SP.ClientContext.get_current();
2. list = clientContext.get_web().get_lists().getByTitle('ListName');
3. var skillcamlQuery = new SP.CamlQuery();
4. //skillcamlQuery.set_viewXml(""+VariableName+""+VariableName+"");
6. skillcamlQuery.set_viewXml(""+VariableName+"");
7. this.skillcollListItem = list.getItems(skillcamlQuery);
8. //clientContext.load(list);
9. clientContext.load(skillcollListItem);
11. var callback = clientContext.executeQueryAsync(Function.createDelegate(this, function(){ _returnParam= onValidateClientSucceeded();}),Function.createDelegate(this, function(){ _returnParam = onValidateClientFailed();}));
19. function onValidateClientSucceeded(sender, args)
20. {
22. var flg = 0;
25. if(skillcollListItem.get_count() >= 1)
26. {
27. flg = 1;
28. }
29. else
30. {
33. }
36. }
38. function onValidateClientFailed(sender, args)
39. {
40. alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
41. return false;
