I'm trying to build a Search page that will search across dozens of lists (all lists use a standard naming based on country). I'm using jQuery Deferred so JS will wait for the functions to end before executing the rest of the code. It's working but only when I have an Alert popping up in my GetResults function. I would like to get rid of the Alert and still get the same results. Once the results from each list are found, they are displayed in a new window in a table.
Below is a short sample of how I'm handling the deferred calls to get the lists based on country and then once that is done, I get the results for each list (full code further below). The problem is inside getResults. Without the "Alert" to display which list that I'm querying, it appears to not wait on the results of the query. When the Alert displays, as long as I don't click it too quickly, it works.
How do I force it to wait until the SharePoint CAML query is complete before moving on to the next list in the array?
//not real code, just a sample of the main code - see full code below
$.when (
getAllLists()).done (function() {
for each list, call getResults { getResults(thisList).done (function() { }); } Display New Window with htmlTable value }
