While handling an asynchronous request, the value of responseText always has the current content received from the server, even if it's incomplete because the data has not been completely received yet. Pass multiple JSON objects to MVC3 action method. This will create a key-value pair with file as a key and the content of the passed file as a value. While handling an asynchronous request, the value of responseText always has the current content received from the server, even if it's incomplete because the data has not been completely received yet. The XMLHttpRequest object is a developer's dream, because you can: Update a web page without reloading the page; Request data from a server - after the page has loaded ; Receive data from a server - after the page has loaded This could prove difficult to manipulate and analyze.
