Recently the head confused like a group of paste, has been wrong.The HTML code, for example, now wants to implement a feature that is based on an AJAX request and gets a specific button to update its style. Because the button is more, each button is set ID, there is no meaning, want to through jquery's Traversal + descendants implementationCore code:$ ("#contentDiv"). Children (). each (function() {Console.log ($ ( This). Children (). Last (). text (). Match (/\d+/) + "); Console.log ($ ( This).

Reading Notes Objective c ++ Item 44 extracts code irrelevant to template parameters and implements tiveitem1. using a template may result in code Expansion Using templates is a good way to save time and avoid code reuse. You do not need to manually enter 20 identical class names. Each class has 15 member functions. Instead, you only need to enter a class template, then let the compiler instantiate 20 specific classes and 300 functions you need for yo

The recent work in the code to write in a string of all the numbers to be extracted out of such a small function, the study of the discovery method is quite many, it is worth recording, so how to use PHP to extract the number of strings in the function of a small summary, summed up three ways are as follows:The first method uses a regular expression:functionFindNum ($str= ' '){ $str=Trim($str); if(Empty($str)){return‘‘;} $reg= '/(\d{3} (\.\d+)?) /is ';//regular expressions that match numbers

(NAIVEBAYESIANMODEL,NBC). Naive Bayesian model originates from classical mathematics theory, has a solid mathematical foundation, and stable classification efficiency. At the same time, the NBC model has few parameters to estimate, less sensitive to missing data, and simpler algorithm. In theory, the NBC model has the smallest error rate compared to other classification methods. But this is not always the case, because the NBC model assumes that the properties are independent of each other, and

Array_slice () Definition and usage The array_slice () function extracts a value from the Array Based on the Conditions and returns it.Note: If the array has a string key, the returned array retains the key name.

There are a wide range of inefficient office practices, such as a yearly self-rating. A breakdown of the scores for the Word document, one item per line, each item to fill in the score items and scores, the team leader after the audit into Excel submitted. The main concern is that a list of scores in a Word document is going to be translated into an Excel line, and if a person copies it, pastes it into Excel, copies it, and then transpose it. A lot of people, looks very troublesome. Then wrote a

, the header named file is BP, A1, test, etc.If you want to extract the "BP" and "P" values for rows that contain "ADD" and the corresponding columns of that row, you need to use the following commandawk '/add/{print $1,$7} ' file > File_bp_p/add/means searching for rows with "ADD", which means extracting the first column, $7 means extracting the seventh column, file referring to the filename of the search, ">" for the output, file_bp_p representing the file name saved after the outputLinux

JSON is a bit more complex than the general format, like arrays, there are multiple layers of nesting, studied, the record code is as follows:stringJsontext ="{' name ': ' Test ', ' phone ': ' 18888888888 ', ' image ': [{' Name ': ' Img1 ', ' data ': ' data1 '},{' name ': ' Img2 ', ' data ': ' Data2 ' },{' name ': ' Img3 ', ' data ': ' Data3 '}]}"; Jobject Jo=(Jobject) jsonconvert.deserializeobject (Jsontext); stringZone = jo["name"].　　ToString (); stringZone_en = jo["Phone"].　　ToString (); Jarr

The first method:You can use the Javadoc tool. It can be extracted from the program source code such as classes, methods, member variables and other documents to form an API supporting documentation. However, when writing code, it is necessary to comment on certain specifications. The development documentation for the code can be generated at the same time through the Javadoc implementation tool. The Javadoc tool is located under the C:\Program files\java\jdk1.6.0_10\bin path.Where/**...*/this a
