Using selectors and events for the jquery start-up tutorialjquery offers two ways to choose the elements of HTML:
The first is to combine CSS and XPath selectors to form a string to be transferred to the jquery constructor (for example: $ ("DIV > Ul a"));
The second is to use several methods (methods) of the JQuery object. Both of these methods can also be combined to use together.
To test these selectors, let's try to select and modify the first ordered list in our starterkit.

English Original: Using HTML5 Input Types to Enhance the Mobile browsing Experience
Browsing the web on mobile devices have become incredbily popular over the past few years. However the browsing experience on these devices can sometimes leave a lot to be desired.This is especially true if it comes to filling in forms. Luckily the HTML5 specification introduces a number of new input types that make it easier for users to fill in your Web F Orms on mobile devices.In a rather awesome
your program execution encounters the await keyword, we want to happen two things:• To make your code asynchronous, the thread that is currently executing your code should be freed. This means that, in a normal, synchronized perspective, your method should return.• When the task you await is completed, your method should continue from its previous position, as if it had not been returned earlier.In order to do this, your method must be paused when it encounters an await, and then resume executi
gap in the internal working mechanism: vectors use an entire array (to store elements) and need to reallocate the entire space when there is an occasional need to expand capacity. While the elements of deque are stored in a variety of different storage spaces, the container maintains the necessary information internally so that any element can be accessed directly through a uniform continuous interface (iterator), and the time required for access is constant. As a result, the internal mechanism

Extract the inside of the code, placed in your Web server (translator Note: The download method as shown, the original author's picture is git before the revision, does not apply to the present, so I ventured to replace it)
After the download is unpacked, you will find that this is already a complete codeigniter framework. This allows you to u
