With the popularity of Windows 7, the team of IE 8 browsers has gradually grown. however, we suddenly found that many web pages have problems. Even worse, our website editor is useless, and all the buttons are useless, even other browsers.
This is written in a buddy's post. Open the editor. js file under include and there is such a code segment:If (element. yuseronclick ){Eval (element. yuseronclick + "anonymous ()");}OrIf (element. yuseronclick) eval (element. yuseronclick + "anonymous ()");OrI

Browser Detection Method
1. Object Feature Detection: a common method for determining browser capabilities. This method can be used if you are more concerned with the browser's capabilities and do not care about its actual identity. The common native Ajax write method uses this method to create XMLHttpRequest:Copy codeThe Code is as follows: IXHR: function (){If (window. ActiveXObject ){XHR = new ActiveXObject ('Microsoft. xmlhttp ');} Else if (window. XMLHttpRequest ){XHR = new XMLHttpRequest

3. Continuously track users' geographical locations
4. Interaction with Google Map or Baidu Map to present location information
Geolocation API is used to share the user's current geographic location information to a trusted site, which involves the user's privacy and security issues. Therefore, when a site needs to obtain the user's current geographic location, the browser will prompt "allow" or "deny ".
First, let's look at which browsers support the Geol
Sprint (S edition)
The S-Version full price machine (bare metal) purchased at Apple's official retail store is unlocked.
The full price machine purchased at the sprint business Radioshacktargetwalmartbestbuy still belongs to a lock machine.
Domestic users note: The sprint version uses the UICC SIM card of a special sprint operator, unlike other operators ' SIM cards!
Mobile phones and UICC SIM cards are always detected and paired, only Sprint's SIM card!

Machine learning is accelerating the pace of progress, it is time to explore this issue. Ai can really protect our systems in the future against cyber attacks.
Today, an increasing number of cyber attackers are launching cyber attacks through automated technology, while the attacking enterprise or organization is still using manpower to summarize internal security findings, and then compare them with external threat information. Intrusion detection systems deployed in this traditional way often
This article describes how to use JavaScript to obtain browser information and how to obtain browser addresses and parameters. For more information about browser information, see the navigator object in Window. we can use a series of API functions to learn browser information.
The JavaScript code is as follows:

How to obtain browser Information
Window has a navigator object to let us know all the information about the browser. We can use a series of API functions to know the information about the browser.
The JavaScript code is as follows:
The Code is as follows:

I. Check the browser nameProblem:Different browsers have different standard support for javascript. Sometimes you want the script to run well on different browsers. In this case, you need to check the browser and determine its name, write scripts for different browsers.Solution:Use the appName attribute of the navigator object.For example, to check whether the browser i

Detecting a browser is an important task in writing cross-browser js programs. From time to time, we need to write branch code for different browsers.The following is an example:Copy codeThe Code is as follows:// Add the event tool functionFunction addEvent (el, type, handle ){If (el. addEventListener) {// for standard browsesEl. addEventListener (type, handle, false );} Else if (el. attachEvent) {// for IEEl. attachEvent ("on" + event, handle );} Else {// otherEl ["on" + type] = handle;}

The original ff 3 is changed to xmlHttp. onreadystatechange = xmlHandle (); however, with parentheses added, IE does not work. Alas, FF was originally regarded as a chicken skin. Now I feel that FF is purely named as a "standard support, it is a waste of time for programmers. However, this program is really important, and there is no way to debug it again to see if there is a simpler way, as shown below:Copy codeThe Code

Bridging mode is a structural design pattern.
Design intent: Separate the abstract and implementation parts so that they can be independently changed.
When you see the design intent, you may be a little confused, we see that the inheritance and interface are not both abstract and implementation of separation. In particular, interfaces and abstract classes are such implementations. Then why is there such a bridging separation?
Let's look at an example first.
For example: The car brand built-in
