Accessing Local Files with jQuery

问题 I believe that this question has been asked in a few different forms, but I've read quite a few different responses. At first, I had a web-application written with mostly jQuery that would make use of servlets to retrieve information from various locations JavaScript could not access (ie. Feeds, images from a server, etc.). Now, however, I've been told to do away with the servlets and application configuration classes so that this project of mine contains only HTML, CSS, and JavaScript/jQuery

How to enable loading local file using ajax in IE9

阅读更多关于 How to enable loading local file using ajax in IE9

问题 I know there is the origin problem, but setting up a web server is not an option here. Firefox v14 has no problem loading a local file. Chrome has no problem after adding '--allow-file-access-from-files' Is there any way to fix also IE9? Thank you Edit: I figured out the solution. Just use ActiveXObject("MSXML2.XMLHTTP.6.0") instead of XMLHttpRequest() for IE9 to overcome the local file access deny problem. 回答1: Ajax or not. HTTP is a client-server application protocol. Without a server, that
