由 拟墨画扇 提交于 2020-01-02 05:44:07
问题 I am building a simple ajax chat client for a school project and have thought of a way to implement this, but it seems IMO to be very cumbersome approach: 1) User A sends message which is accepted by a server-side PHP script and saved to database 2) The browser of User B periodically launches a server side PHP script to check if there are any messages in the database for User B. PHP script finds messages from User A and returns them. Is this the right approach? Can communication between these

How long will a browser remember a “a:visited” link?

问题 How long will a browser remember a "a:visited" link? Assuming the method isn't uniform across browsers - an answer for any individual browser (or as many as you know) would be helpful. Also, under which type of memory is it stored? "Web History"? Cache? 回答1: Visited links are part of your web history, and how long they're stored depends on each user's individual browser settings. I believe Firefox remembers unlimited history by default, but anyone can set a time limit on it, or have it be

To upload documents successfully having large size and slow internet connection, I've compressed the images and it solves my issue. But the user can also upload PDF files of

由 。_饼干妹妹 提交于 2020-01-02 04:16:16
问题 How do you get words to wrap inside a box in RaphaelJS? Or in browser-based SVG in general? I found this thread on it, but it doesn't make any sense. They say to use "widthToCharNum" but as far as I can tell, this thread is the only place those words have ever been used on the internet. They suggest using a "width" attribute, but this has no effect. 回答1: Text-wrapping is not built into Raphael or the SVG spec. Period. Coming from the HTML world, I found the absence of text wrapping pretty
