each stationmaster more or less will make some code modification to the file, when patching the time if directly overwrites the patch file, then the code that has been modified before has no. So we need to do a code comparison and then synthesize a special patch package that retains both our previous modification code
Key points
Why not use the String.CompareTo method to compare the client version number?
For example, the client version number is: 9.9.9, and the server-side latest client version number is: 10.0.1, although 10.0.1 is significantly higher than 9.9.9, but according to the CompareTo method, this 9.9.9 is greater than 10.0.1, causing the client version number to compare incorrectly.
Java
In the JS front-end interview process, often encounter such a written question: JS in how to compare two JSON objects are equal to the instance code, the following small make up some time for everyone to clean up, together to see.
1. Prepare three tool methods to determine whether it is an object type or an array, get the length of the object
function Isobj (object) {return
object typeof (object)
1. beyond compareIntelligent comparison
Beyond compare is focused.
Beyond compare allows you to quickly and easily compare your files and folders.
By using simple, powerful commands you can focus on the differences you're interested in and ignore those you're not. Y
Ou can then merge the changes, synchronize your files, and generate reports for your records.

Avascript compares two dates and returns a negative value, indicating that the latter is greater than the former.The function passes the test under Ie,firefox.Java code
/**
Compare two days with different dates, can be negative
**/
function DateDiff (sDate1, SDate2)
{ //sdate1 and sDate2 are 2002-12-18 formats
var adate, oDate1, ODate2, idays;
Adate = Sdate1.split ("-");

We often encounter different versions of the same file that need to be compared, especially the code files. If the manual to compare the view, it will be time-consuming strength and error, so we need to use some code comparison tools to automate these tasks. Here are 3 of the more popular and powerful tools.1. Beyond Compare
This article mainly introduces how to compare the code changes in two folders in Python. The example analyzes the skills related to reading files and string operations in a folder in Python, which has some reference value, for more information about how to compare code changes in two folders in Python, see the example
A detailed description of the Similar_text and similarity Levenshtein functions for calculating string similarity in PHP
$first = "ABCDEFG";
$second = "AEG";
Echo Similar_text ($first, $second); result output 3. If you want to display as a percentage, you can use its third parameter, as follows:
$first = "ABCDEFG";
$second = "AEG";
Similar_text ($first, $second, $percent);
Echo $percent;

Look at the following two ways to implement: JS checkbox method One:Copy CodeThe code is as follows: function Checkall () {var code_values = document.all[' Code_value '); if (code_values.length) {for (Var i=0;iif (code_values.length) {for (Var i=0;icode_values[i].checked = false; }}else{code_values.checked = false;}} function Multipledelete () {var num = 0; var code_values = document.all[' Code_value ']; if (code_values.length) {for (Var i=0;iDocument
If the value does not duplicate the case, you can use Array_flip () to Exchange keys and values, and then Krsort (), and finally Array_flip () Exchange back, you can compare size. If you want to intercept an array, you can use Array_slice ().
If there is a duplication of values, some sort algorithms are used, but PHP has a powerful function uasort () that uses a custom comparison function to sort the values in the array and keep the index associated,
actual operation, will specify the dead version of the format bar. such as 1.2.3 and 1.0.0. In addition, I see the actual code, as long as the discovery of two versions of the string is not the same, remind users to update the version--.3 Code Public intcompareversion (String version1, String version2) {if(Version1.equals (version2))return0; intFversion1, Fversion2;//The leftmost string represents the
