阅读更多关于 Keeping track of number of button clicks

问题 Let us assume that I have a page with a CAPTCHA image. I want to let the user try to enter the code for three times, otherwise he is not allowed to do it anymore.

阅读更多关于 Stop jquery TABS from jumping / scrolling up when clicked on?

问题 The engine I use calls the jquery tabs.js script to handle the tab functions. Problem is that anytime the tabs are at the top of the page and you click on a link, they quickly scroll back down towards the bottom of the page.

问题 As the title says I want to know the exact position of the item when I click on a view that is inside the item.

Tracking visitor IP/Clicks in PHP

阅读更多关于 Tracking visitor IP/Clicks in PHP

问题 I am trying to write a script or more like come up with a simple logic to track clicks or visits. I don't need to track each page, just as long as they land on the homepage is where I want to store it as 1 click. First of all, is it safe to say that tracking by IP is far from accurate because many users can be under the same IP?
