Web developers talk about new features of IE8 browsers

Microsoft last year was a relatively large year, the latest version of the IE8 browser launched last March, and at the end of the year released a new operating system of Windows 7, since the new product's market share has been a small increase in the upsurge. "Microsoft's IE8 face is not only ordinary browser users, from the IE8 browser with the" Developer tools "we can see that it is a web developer facing the platform. "Although Microsoft has already proposed that the lower version of IE users upgrade browsers to the latest generation of browsers IE8, but there are many users are hesitant to upgrade the browser to IE8, this time we will be from the perspective of Web developers to upgrade the problem of IE browser."

In January this year, IE8 's Global browser market share surpassed IE6 to become the most widely used browser in the world, according to the latest data from research firm Netapps. IE8 market share reached 22.31%, higher than last December's 20.86%. IE8 was officially released from March last year, meaning IE8 only 9 months into the league of browsers.

Microsoft has already advised users to abandon the use of the old version of the IE6 browser, some time ago due to IE6 in the vulnerability caused by Google and other 33 companies suffered extensive network attacks, Microsoft released an emergency patch to repair IE6 loopholes. Even so, however, Google announced it was about to give up its support for IE6. In addition, prominent websites such as Facebook, Digg and YouTube have all announced the end of support for IE6.

However, the status of IE6 in mainland China has almost never changed, from January 2009 to January 2010, IE6 's share from 58.26% to 59.67%, not only did not reduce the increase, it can be seen that IE6 's position in the country is difficult to waver.

So as a developer, how do you look at this problem, should you upgrade to IE8, then let's start with some new features of IE8:

1. Active Content Service

Active content services, which means that users can quickly access services from Web services, users typically copy and paste the contents of a Web page, where the content is sent to a Web application, for example, when a user sees a restaurant address on the page, and he can send the address he sees to the map service. In other cases, such as when a user sees an interesting article, he can also use the feature to send some text to a blog. For the content of the active service, the user can install or manage it.

2. Web Subscriptions

WebSlices is a new feature, when users access the network can not open the site to view subscriptions, WebSlices seems to be similar to feeds, Microsoft's demo for subscribing to the weather forecast.

3. Favorites Bar

Previously IE7 favorites have been expanded into a complete favorites bar, which can add favorite sites and include addresses for Word, Excel, and PowerPoint files.

4. Automatic failure recovery

Users of IE series browsers are often able to run into IE-browser crashes. After you open IE again, the Web page you just browsed is not saved, and you don't even know where to find them. The ACR automatic fault recovery feature is an important improvement in IE 8 browsers. When IE browser crashes, ACR automatically saves user-browsed pages and restores them.

5. Improved Anti-Phishing filter

The network anti-Phishing Filter provided in IE7 is promoted in the new IE8, which pops up and warns users of possible threats when they encounter a possible phishing website. And a new "secure filtering" feature is added, which, in addition to continuing to block known phishing sites, can also check known malware to reduce the theft of personal information from users.

So what are the new development tools that IE8 for developers?

· HTML element, now using the IE8 development tool, we can arbitrarily select an HTML element, on the page immediately display the outline of the element, and can see the elements of the element to where, more conveniently we can directly see this element in the browser parsing the Run-time style display, What's even more incredible is that we can change the enabled or disabled part of the style at run time and see that browsers without this part of the style display.

• We do web development know that the most important part of client debugging is debugging JavaScript. Especially the Web2.0,javascript and the river crab as the bully. IE8 javascript Debugging tools, can be compared with VS2008 client debugging capabilities, with IE8 we can easily debug any page of JavaScript in a notebook

Selecting a script on the left tab of the debugging tool will see the script in the page. And we can see all the script files referenced in the page, and randomly choose to set breakpoints, in its upper right corner, there is a search script function, very convenient, but also to show all breakpoints, local variables, monitoring and so on. It can be said that using IE8 Web script debugging is no longer a problem.

In addition, the IE8 development tool can also clear the client cache for a site separately, and you can clear cookies for a site separately.

• When you want to view the layout style of a Web page, you can open the development tool, select "Contour", select the frame elements you need to display, such as table tables, tables, Div, and so on, you can also choose whether to display the class name (classes) or ID name.

• You can use the ruler inside the tool to measure the spacing of the page content, you can use the color picker to wash away the color of any area of the page, and copy to the Clipboard.
Overall, although there are some deficiencies in the IE8, such as the memory used to open multiple pages is a bit high, but IE8 can be more convenient for ordinary browser users and web designers, and, in terms of security IE8 also has a great increase, which is also a IE8 browser's biggest bright spot. The use of IE6 browsers will become increasingly inconvenient as more and more people call on those who are still using IE6 to abandon IE6, and as more and more global websites cancel their support for IE6. If you're still hesitating about whether you should give up using IE6, then upgrading to IE8 will be a very good decision. Before the IE9 official edition is available, we want more users to understand and use IE8.
