Oracle Application Express (APEX 4.2) for ajax calls, apexajax
Oracle Application Express 4.2 (APEX 4.2) is a quick web Application development tool. Ajax requests are sometimes used during web page development.
How to create an ajax request:
1. Create background processing:
Step 1
Step 2
Step 3
In this way, the background processing is completed.
2. Compile js on the frontend:
Function ajaxTest () {apex. server. process ('test', // name of the background processing, case sensitive {}, //

3 In addition to the lowest position of the bit1, the rest of the total Qing 0.
n = N (ñ-N)
Analyze:
Suppose n (2) = X ... X10 ... 0. Each x represents the bit value is not all the same, the number of 0 ≥0, #175; X indicates that the bit is reversed.
X #175; X = 0, 1 0 = 0
Then ~n (2) = #175; x... #175; X01 ... 1.
~n + 1 = #175; x... #175; X10 ... 0.

ask users to classify the synthesized images and real images.Display 50 images randomly selected by each user and 50 images in random order, showing the user a continuous display of 20 pictures at a time. Overall analysis, 10 users can choose 517 times (p=0.148) from 1000 (50+50) X10 attempts, which is slightly better than chance. Table 1 is a confusing matrix.Instead, show 10 real images and 10 synthetic images per user, 200 times (10+10)
compare two struct Foo objects.Gives an example of a string comparison to determine if the first four characters in string str are 0x80100001 because 0x00 is a terminator for a string, if you use strncmp strncmp (str, "/x80/x10/x00/x01", 4) , the actual effect is only to determine whether the 0x8010 is included, which means that once the first two characters in Str are 0x8010, the return of 0 indicates the same, which is obviously incorrect.

Samsung's shortcut keys are simple and provide the most common features, but the new X-Series and the FN shortcuts for P-series machines vary widely, such as X10 and P25. Now introduce the FN shortcut keys to the X10 of the main, add the explanation P25.
fn+ up/down ARROW keys: increase/decrease brightness,
Fn+ left ARROW key/Right direction key: Increase/Decrease Volume (P25: Fn+page up/page down).

The red Rice Note2 is a new product that was released just last week from the product side, although the machine does not have fingerprint recognition function, but it is an absolute high distribution mobile phone, the machine using MediaTek new Helio X10 series eight core 64-bit processor, i
The sequential algorithm (sequential algorithms) is a very simple clustering algorithm, most of which use all eigenvectors at least once or several times, and the final result depends on the order of the vectors participating in the algorithm. This clustering algorithm generally does not know the number of clusters of k, but it is possible to give a clustering number of the upper bound Q. In this paper, we will mainly introduce the basic order algorithm (sequential algorithmic Scheme,bsas) and s

PHP and other programming languages, any function that accepts parameters must declare these parameters in the first part of the letter. Although these parameters (value parameters) accept values outside the function, they are no lon
Step One:
First to create a canvas, the canvas size can be arbitrarily adjusted, but not less than 10x10 px, because we do not have the size of the pattern can be less than ten X10 px, the article uses the X-px, which can be "magnified", "narrowing."
Step Two:
Zoom to Maximum
Step 3:
Start drawing with the Pencil tool
Step 4:
