问题 I'm trying to find a way to subscribe to double-click event in XNA, and googling gets me winforms related stuff, which isn't the case, I can't use that. Using Timespan and guessing how long the timeout for double click is on a PC is not very reliable.

阅读更多关于 Using ExitAPI in a HTML5 ad banner with parameters

问题 I have created a banner for Adwords, using HTML5 with a form element, which accepts few inputs, like your preffered color, type, etc. The whole banner is not clickable, only the submit button, which I achieved by adding "onclick="ExitApi.exit()"" to the button.
