I have to say, I love JQuery. Before 2 years ago, I was a complete and utter JavaScript noob, and quite frankly I feared it. But when I began getting to grips with this gem of a JavaScript framework, my eyes opened up to an entirely new world!
Ok, enough gushing and onto my discovery. I have a website that currently makes multiple ajax calls to retrieve a bunch of lookup lists etc. Before I can setup a grid I have on the page, which makes use of these lookup lists, I need to wait for all these calls to return before I can initialize my grid with the data. Enter JQuery’s when, then concept. This is only available from JQuery 1.5 onwards.
function getLookupListOne(){ return $.get('lookup-list-one-url.json', function(data){ for(var i = 0; i < data.length; i++){ lookupListArrayOne[i] = "Some global array data you might want to initialize..."; } }); function getLookupListTwo(){ // Content left out for brevity }); function getLookupListThree(){ // Content left out for brevity }); $(document).ready(function() { $.when( getLookupListOne(), getLookupListTwo(), getLookupListThree() ).then(function(){ alert('All AJAX Methods Have Completed!'); )}; });
