As front-end development is becoming increasingly intensive and Ajax and JSON are used more and more frequently, you must use a large number of tags in front-end development. If it is simpleCodeThe combination may be better, but if the page uses a large number of similar structures, unless it is always the sameProgramP

converted to a specific time, this will return the GMT format "Wed Dec 23:59:30 GMT +0800 (Chinese Time)" (reminder: Each call to the SetTime () method of a Date object changes the value of the object itself.

amounts of data, because each time a page is requested, the cookie is sent to the server, which makes the cookie slow and inefficient. So the size of the cookie is limited to about 4k (different browsers may be different, sub-host), as follows: Firefox and Safari allow up to 4,097 bytes of cookies, including the name (name), value, and equal sign. Opera allows up to 4,096 bytes of cookies, including: Name, value, and equal sign. Internet Explorer allows up to 4,095 bytes of coo

Implementation results:Implementation principle: Give the Close button a fixed point click event and click to trigger the animation effect later. With the animate method of jquery, the box height of the display weather is changed to 0, then the width of the box containing the weather and events is changed to 0, and the Close button disappears by setting the Display property value to none.

Add the number of Li,ul to OL-1, and light the first button.4. Mouse on the ol ' li to switch pictures5. Adding timers6.

In a single-page application, the front end usually requires a set of routing mechanisms so that when the URL changes, it can do some processing so that the page displays different content. Backbone and angular have a set of built-in routing implementations, but sometimes you may not want to use the entire framework, only the part of the routing process, then look at how to implement the

Recently, I took over a project and used aspx.net for web development. However, it is really awkward to do so because there are many functions that can be processed at the front-end, however, due to the use of a lot of webcontrol, continuous PostBack occurs. It may be better if Ajax is used for processing. Currently, you can only bind front-
