What is the difference between Local Events and Global Events in jQuery?
Ajax requests produce a number of different events that you can subscribe to. There are two types of events:
Local Events
These are callbacks that you can subscribe to within the Ajax request object.
$.ajax({
beforeSend: function(){
// Handle the beforeSend event
},
complete: function(){
// Handle the complete event
}
// ......
});Global Events
These events are broadcast to all elements in the DOM, triggering any handlers which may be listening. You can listen for these events like so:
$("#loading").bind("ajaxSend", function(){
$(this).show();
}).bind("ajaxComplete", function(){
$(this).hide();
});Global events can be disabled, for a particular Ajax request, by passing in the global option, like so:
$.ajax({
url: "test.html",
global: false,
// ...
});
