This article mainly introduces JavaScript code used to identify the uc browser. For more information, see.
If (navigator. userAgent. indexOf ('ucbrowser ')>-1) {alert ("uc Browser");} else {// operations not performed by uc browser}
If you want to test the features of a browser, you can obtain them using the following methods:
JS to get browser InformationBrowser code name: navigator. appCodeNameBrowser
Browser compatibility is the first problem to be solved by the browser development framework in front-end development. To solve the compatibility problem, you must first determine the browser type and version accurately, the browser version can only be known by analyzing the browser's userAgent. today, we will summarize various judgment methods and hope to help you obtain browser information through JS.

window.
Next, we need to hide or display the Window Based on the menu status. To do this, I first try to remove the menu. I used status variables to track the window of the last release menu. It is possible that the menu cannot be removed. I will handle this error. Of course, I have not performed any operations in the processor. I also used a status variable tracking menu for visibility. This process of removing the menu partially resets the state variable.
Public Function togglemenu (): void
Sometimes you need to write styles based on the browser. so you need to judge the browser type. Baidu only knows that JQuery has a method to directly judge and attaches the native js judgment method, share it with you. For more information, see.

IOS Sprite Kit Tutorial Programming and Xcode Introduction Xcode interface IntroductionA Xcode project consists of a number of files, such as code files, resource files, and so on. Xcode helps developers manage these files. Therefore, Xcode's interface is also more complex, as shown in 1.40.Figure 1.40 Xcode's interfaceIn Figure 1.40, you can see that the Xcode interface can be roughly divided into 4 parts.
The part with Q number 1 is the navigation window.
The part of Q number 2 is

The initiator page uses iframe. contentWindow. opener = {a: function (params ){...}, b: function (params ){...}...} to define the method that can be called by the receiver.C. The receiver page calls the method defined by the initiator through window. opener. a/window. opener. B.D. The recipient page uses parent. opener = {c: function (params ){...}, d: function (params ){...}...} to define the method that can be called by the initiator.E. The initiator page uses op

The user agent string userAgent can implement four identification functions: String useragent

User proxy string: navigator. userAgent
The HTTP specification clearly stipulates that the browser should send a brief user proxy string, specifying the browser name and version number. But in reality it is not that simple.

This tutorial is based on the project you built in the previous lesson. After completing this tutorial, you will use the view, view controller, actions, navigation content you learned earlier, create some key user interfaces for your app, and add behaviors to your sceneHere's what this lesson is about:1. Use storyboard to define app content and processes2. Managing multiple View Controllers3. Add an action to the element on the user interfaceAfter completing this tutorial, your app should look l
The Bodenseekreis plane crash may be an isolated event, but there is widespread universality.The cause of the accident was due to two co-operative navigators, one being Candide, the other always skipping classes on the toilet or stocks. An honest man has to do two men's work alone.Finally one day, he made a mistake. And this error, can avoid the reason, but also the telephone line is not enough, there are all the way bad, and no one to repair.The result is that more people do things, more mistak
created by the utility application template.
This is the first time that we use Utility application. So here we will give a brief introduction. Utility application will automatically create two views for us. The first view is called main view, the second view is flipside view. There is an information button on the main view. Clicking this information button will switch to flipside view. There is a done button on the navigator bar of the flipside view
Javascript scripting is an object-oriented
Programming Language It also supports some simple object models supported by predefined objects.
Javascript objects are composed of two basic elements: attributes and methods.
Navigator object The navigator object manages the basic information of the browser, such as the version number and operating system.Appname display browser nameAppversion browser version

In fact, it is not difficult to achieve, we first the implementation process to think about, first of all, if the navigation in the scope of the display, you do not have to make changes. When the navigation is out of range, that is, the distance from the top of the screen is less than 0, we have to float it on the top of the screen, and then more than 0, to do a recovery operation, the principle is so simple, roughly look at the effect of the picture
