biggest headaches about JavaScript is that its variables do not have a specific scope. Generally, all variables, functions, arrays, or objects are global, which means other scripts on the same page can access and overwrite them. The solution is to encapsulate variables in an anonymous function. For example, the following definition generates three global variables and two global functions:

Php uses session to defend against url attacks and phpsession to defend against URLs
This article describes how php uses session to defend against url attacks. Share it with you for your reference. The specific implementation method is as follows:
Through session tracking, you can easily avoid url attacks. php uses the session anti-url attack method Code as follows:Copy codeThe Code is as follows: Session_start ();$ Clean = array ();$ Email_pattern = '/^ [^ @ s If (preg_match ($ email_pattern,

applications using this architecture is fairly straightforward. This will be a learning curve that does not often occur (for example, if you use Nancy for MVC). However, even if the composition method does not work, using OWIN also has an extraordinary advantage, that is, you can still use ASP. NET Host (MICROSOFT.OWIN.HOST.SYSTEMWEB) to host the OWIN pipeline inside IIS. Give it a try and see what your thoughts will look like.

The feasible principle is that events Support bubbling and the code is as follows:Copy codeThe Code is as follows:(Function (){Var resources = document. getElementById ('resources ');Resources. addEventListener ('click', handler, false );Function handler (e ){Var x = e.tar get; // get the link thaIf (x. nodeName. toLowerCase () = 'A '){Alert ('event delegation:

Swift the next dayA. DictionaryThe dictionary in Swift does not store arbitrary objects like OC, and the dictionary in Swift needs to define the type of stored key values in advance, can specify the type directly, or let him infer it himself.The Dictionary of Swift uses the Dictionary definition.var dic = ["FirstName": "Chris", "LastName": "Paul"]//Create dictionary directlyvar dic1:dictionarydic["Team" = "LAC"//This allows you to add a key-value pair
follows:
var name = ' Chris ';
var age = ' 34 ';
var status = ' single ';
function Createmember () {
// [...]
}
function Getmemberdetails () {
// [...]
}
After the encapsulation is as follows:
Copy Code code as follows:
var myapplication = function () {
var name = ' Chris ';
var age = ' 34 ';
var status = ' single ';
return{
Createmember:function (
);

E.preventdefault ();

(5) anonymous function
One of the biggest headaches of about JavaScript is that its variables don't have a specific scope. In general, any variable, function, array, or object is global, which means that other scripts on the same page can access and overwrite them.The workaround is to encapsulate the variable in an anonymous function. Fo
statements, you can create the same functionality as C, but the direct access is no longer automatic. You have to ask for it explicitly.
The deeper implication of not using a direct function is that you can arrange the labels arbitrarily, such as placing the default label in front of all other tags. To illustrate it, I created an example of deliberately not ending loops:
Switch (nsomething)
{
Default
Case 5:
goto default;
}
