问题
While I was trying to refresh page contents dynamically using Ajax/JQuery, I have learned about the S-O-P issue and restrictions, however I was wondering if there could be a way to solve my little problem.
To make it easier to understand I will first explain the workflow.
I do receive web pages via email, that is HTML emails. The web pages contain HTML forms in such a way, once the form is complete it is sent to the proper web server (php) to store data.
I mostly use Outlook 2007 as my email client (don't say anything here, I know!!!), but for some security restrictions, IFRAMES are disabled when "opening" the email. I have circumvented this problem using a VBA script that copies the whole page content, saves it on the filesystem as a stand-alone web page and loads into the browser (Firefox).
Once the page is loaded into the browser, the address bar shows a local/filesystem URL, such as
file:///C:/Users/Bob/Desktop/outlookpage.htm
Till here no problem, works fine; now the problem:
I wished to dynamic update page contents using Ajax, using jQuery.load, however that's where the S-O-P comes in. The PHP page being loaded to dynamically update the web page is seen as running on another domain, thus being blocked.
I was wondering how to circumvent this.
回答1:
That's not going to work because in order to bypass the same origin policy, you would need to use a proxy on the same domain, which will then communicate to the page that's handling the data on a different domain. There's no way to generate a proxy script on another user's computer (or at least, there SHOULDN'T BE A WAY). I would either just post the form normally, which will open the user's default browser, or provide a link to an online form in the email. The link should be provided anyway, in case their email client doesn't support HTML email.
