This is often the case. When the content displayed on the page is too long, you have to pull the scroll bar back to the top if you want to switch the navigation column. This operation is not user-friendly, can I automatically paste the navigation outside the display range to the top of the screen? The answer is yes. If you don't quite understand it, pull the scroll bar to the bottom and check my blog to see the effect.

Q: Which browsers support JavaScript?
A: JavaScript is supported in the following browsers:
Netscape Navigator (starting from 2.0)
Microsoft Internet Explorer (starting from 3.0)
Other vendors have licensed or implemented JavaScript interpreter browsers or products (such as opera).
See the version of JavaScript.

Eclipse project. This project is divided into subprojects, with one owner in each subproject. Large subprojects are divided into groups, and each group has a person in charge. Most of these management roles are currently owned by the IBM affiliate Object Technology International (OTI), which originally developed Eclipse, but as an open source project, it welcomes anyone's involvement. The responsibilities of any particular department are sought through the contribution of the Department to the

Because the browser thought it was linked to the same page, it couldn't find the defined bookmark (anchor) and stayed at the top of the page. Replace the "#" of the Empty link with "javascript:void (null)" To solve the problem.
3 The use of CSS, layers of time, in different browsers, sometimes even dislocation phenomenon, how to solve?
Dreamweaver does well in terms of compatibility with different browsers, but it does not mean that Web pages made with Dreamweaver
control the markup format.
HTML formatting can be imported and exported from Whidbey to ensure that the markup style is standardized for team development. It is easy for developers to apply HTML formatting rules to existing tags to handle the need to update existing HTML source files with new formatting rules.

If you do not have a deep understanding of javascript, it is easy to write incompatible code (like me). At this time, you have to judge the browser. For example, event listening, mouse and keyboard events, and Range events are different. The following lists several common browser detection methods to attract viewers!
Check the code of the browser and its version
The Code is as follows:
GetBrowser: function (){Var browser = {Msie: false, firefox: false, opera: false, safari: false,Chrome: false
JQuery 1.9 removed the $. browser alternative, jquery. browser.
$. Browser uses regular expressions to match userAgent to determine the browser version and type. jquery has been declared in the jquery1.3.2 document. browser and jquery. browser. we recommend that you discard the version. You can use jquery. support.JQuery removed $. browser and $. browser. version from version 1.9 and replaced it with $. support. In the latest version 2.0, IE 6/7/8 is no longer supported. Later, if you need to su
In fact, it is not difficult to implement it. First, let's look at the implementation process. First, if the navigation is within the display range, no modification is required. When the navigation is out of the display range, that is, when the distance between the navigation and the top of the screen is smaller than 0, we need to let it float on the top of the screen, and then perform a restore operation when it is greater than 0, the principle is so simple. Let's take a look at it.Copy codeThe

prompting you to grant access permissions to the user's location. Follow the browser prompts and select related authorization.
If the user has not been granted permissions, the location information is not provided to the Web application. Successful callback is not triggered when related APIs are called.
Check browser support
The geographic location API is supported in the latest mainstream browsers, but to be compatible with the old browsers, check it. If the geographic location API is unavai
the Window object to access or modify the text in the browser's status bar, modify the loaded page, or even open a new window.The Window object is a global object, so you do not need to use its name to access properties and methods. In fact, global functions and global variables, which can be accessed anywhere in the page, are created as properties of the global object.Some properties of the Window object are also objects. Common objects for all browsers include Document,
The Navigator browser object that contains the version information of the currently used navigator. Displays information about the browser currently used. When the Javascript client is running, the engine automatically creates a navigator object.For more details, refer to the description documents after msdn or navigator

In the previous section, we fully touched on the window features provided by JavaScript. Many of these features are based on special browsers, that is, they cannot work in Internet Explorer and navigator at the same time. In this section, we will explore several interesting aspects and some useful techniques.
