[Beginner] an in-depth study of the tag library in JSP-general Linux technology-Linux programming and kernel information. The following is a detailed description. Taglib
Tags are defined and distributed in a structure called the tag library. A tag library is a set of metadata and classes:
1. Tag Processor: Java class that implements the custom tag function.
2. Tag additional information (TEI): provides edge information to JSP containers to confirm tag attributes and create variable classes.
3.
If the HTML Script is like this: formactionP. aspxinputtypecheckboxnamevvaluev1/inputtypecheckboxnamevvaluev2/form when Post, the Action can be like this: publicUser {publicstring [] v {get; set;} [HttpPo
If the HTML Script is like this:
During Post, the Action can be like this:Public User
{
Public string [] v {get; set ;}
}
[HttpPost]Public ActionResult P (User user)
{
...
}
In fact, in form post, the data in POST is v = v1 v = v2.
When Ajax Post is used, because the Post data is Json data, t
Copy Code code as follows:
#include #include #include /* The following is a structure defined to construct a linear list.
typedef struct chaink{
char c;
struct Chaink * NEXT;
}ck;
CK * Chain (CK *,int);
int print (CK *,int);
/* The following is the main function * *
int main (void) {

specified tag library
2 Find specific classes to implement these custom behaviors
The first requirement-find a custom behavior that belongs to that tag library-is done by the prefix of the label directive (Taglib directive ' s Prefix), so elements that use the same prefix on the same page belong to this tag library. Each tag library defines a default prefix that is used in a document in a tag library or in a page to insert a custom label. So, you can use prefixes other than those such as JSP,JS
:**************************************** **************************************** *****1. To enable the JSP Container to use the custom behavior in the tag library, the following two conditions must be met:1. Identify the tag representing this custom row from a specified tag Library2. Find the specific class to implement the custom Behavior
The first required condition-Identify the tag library that a custom behavior belongs to-is completed by the taglib directive's prefix attribute of the tag c
the methods that the Simpletagsupport class has implemented, and if the method implementations of the Simpletagsupport class do not meet the business requirements, then the corresponding method can be rewritten according to the specific business situation.5.2. Tag body type setting details in TLD fileOnce we have developed a simple tag, we need to add a description of the tag to the TLD file, for example:1

the above association rule mining process, the first step is often the bottleneck of overall performance. The Apriori algorithm uses connection steps and pruning steps to find all the frequent itemsets.
1) Connection Step
To find LK (the set of all frequent k sets), a set of candidate K sets is generated by connecting Lk-1 (all the sets of frequent k-1 sets) to itself. The candidate set is recorded as CK. Set L1 and L2 are members of the Lk-1. Li[j]
How is naive Bayesian algorithm understood?Naive Bayesian algorithm is an algorithm of generative formulaOur goal is to classify the current instance of X as that category, but the resulting formula is the P (ck/x)In practical problems we usually know that P (Ck) is called a priori probability. We will also know the number of P (x/ck), the probability of this con
The development of a tag library in a JSP requires only the following steps1. Development of custom Label processing classes2, create a *.tld file, each *.tld file corresponding to a tag library, each tag library can contain multiple tags3. Using a custom label in a JSP fileDeveloping Custom Label ClassesWhen a simple tag is used on a JSP page, the underlying is actually supported by the label processing cl
directives in the tag file
Tag file and JSP are very similar, there are different, the main difference in directives. JSP's directive has include,taglib and page, but tag has include and taglib, no page, and also provides Tag,tag replaces page in JSP, and provides
The Tag directive has the following properties, which are optional: pageencoding : The meaning in the same page that defines the encoding of the tag output. iselignored : The same meaning on the page requires that the EL expressi
KDE4 injected with chicken blood was incredibly exciting. Fast! Fast! Fast! So what is BFS?
To know what BFS is, you 'd better first understand its author, the legendary Australian warrior CK.
CK, Con Kolivas, male, Australian middle-aged man, Senior kernel hacker. As we all know, Linux Kernel is a gathering of talented and arrogant geeks, and CK seems to be the
people, the latest Linux patch supports 4096 CPU computers! Only 1024 supported!
B: Why is the full-screen Flash video card not stuck?
A: card. But who is watching the video?
The message about BFS was first seen on the Linux Magazine. Shortly afterwards, gg1 Android mobile ROM was changed to CM and began to use BFS as the schednel of kernel in his beta version CyanogenMod, after the trial, we found that the speed of the mobile phone system was significantly faster.

Magazine. shortly afterwards, GG1 Android mobile ROM was changed to CM and began to use BFS as the schednel of kernel in his beta version CyanogenMod, after the trial, we found that the speed of the mobile phone system was significantly faster. Sliding the screen on the left and right by hand is as smooth as rolling pages under Opera, resulting in a lot of fingerprint printing on the screen. It has been a long time ago. it coincides with the official release of the new Linux kernel 2.6.31 versi
Determine if there is a selected code instance in the check box:Check boxes are generally multiple, and sometimes we need to decide if they have a selected item, here is an example of how to achieve this effect.The code is as follows:DOCTYPE HTML>HTML>Head>MetaCharSet= "Utf-8"/>Metaname= "Author"content= "http://www.softwhy.com/" />title>Optional number of limit check boxes-Ant tribetitle>Head> Scripttype= "Text/javascript"> functionnum () {varChecboxs=Document.getelementsbyname ("
