Can't get ClientContext.executeQuery() to work in javascript
javascript, sharepoint-2010
Solution
I have been trying something similar in using ExecuteQuery instead of the Async version. And from what I have found the non Async version is not supported in the JSOM. So you have to use the Async version.
Looking at his number 6. http://blogs.msdn.com/b/sharepointdev/archive/2011/07/19/working-with-the-ecmascript-client-object-model-jsom-in-sharepoint-2010-part-3-nikhil-sachdeva.aspx
Problem
I am getting information from a sharepoint list and then I want to use that data. The problem is that I need the data to be updated from the Sharepoint server before I use it, but I can't get executeQuery() to work. I can get executeQueryAsync() to work though. Here is my code: ``` // Global variables; var context; var web; var list; var howManyItem = 0; var allItems; var randNums = []; // Initializes the variables; Sets listname; Gets all items; function init(){ context = new SP.ClientContext.get_current(); web = context.get_web(); // Enter the list name; this.list = web.get_lists().getByTitle('LetsTalkAdded'); // Get item count in the query/list; var query = SP.CamlQuery.createAllItemsQuery(); allItems = list.getItems(query); context.load(allItems, 'Include(Title)'); context.executeQueryAsync(Function.createDelegate(this, this.success), Function.createDelegate(this, this.failed)); } ``` This works fine, but when I change the last line to: ``` context.executeQuery(Function.createDelegate(this, this.success), Function.createDelegate(this, this.failed)); ``` It no longer works, but I can't run them asyncronously. If I do, the parts of my code that depend on that information don't work. Why doesn't the executeQuery() funcion work?
